Characteristics of the tree group that produces fruit at the tip of the branch Lychee belongs to the group of year-round green leafy trees, multi-use trees, both for fruit, shade and landscape. The trees in this group often have the phenomenon of fruiting every year, which means the year of fruiting, the year of no fruit, the year of little fruit, the year of many fruits. Longan and litchi are all fruit-bearing trees, …. That is, the branch from the fall of the previous year is the mother branch bearing fruit next year. If the branch is healthy and the cake is dull next spring, flowers will bloom on the top of the branch. If winter has budded spring leaves do not flower. Therefore, in order for the tree to produce many flowers next spring, it is necessary to prepare many branches from the previous autumn, the branches are old and strong. That depends first of all on the post-harvest care. Longan and litchi trees grow fruit after a year, after harvesting, the branches and leaves fall off, which is the period when the tree is most physically exhausted. From the research results of agricultural experts, after harvesting, the roots are the part that loses the most force, followed by leaves and branches. In order to produce normal fruit next year, folk care experience along with cutting branches, pruning the canopy must be “compensated” or “compensated” in the post-harvest period. The selection of fertilizers and fertilization techniques are very important in order to restore the health of the tree, ensure the recovery, growth and development after 5-6 months of fruiting to continue to produce fruit next season. After harvest, longan and litchi trees need to be cared for and “compensated” so that the next crop can still be productive. Photo: TL. Van Dien fertilizer – The perfect choice for longan and lychee Among the current fertilizers, in addition to organic fertilizers, only Van Dien fused phosphate fertilizer and Van Dien NPK multi-element fertilizer products can meet the above demand for longan and litchi. Easily digestible nutrients in Van Dien fused phosphate fertilizers include: P2O5 15-19%, MgO 15-18%, SiO2 24-32%, CaO 28-34%, and many other micronutrients such as Fe, Mn, Cu, Zn, Bo, Mo…. Multi-factor fertilizer NPK Van Dien 5.10.3 has the content of nutrients such as: N=5%; P2O5=10%; K2O=3%; S=2%; MgO=9%; CaO=15%; SiO2=14%. In addition, there are trace elements such as B, Mn, Zn, Cu, Co… that other fertilizers do not have. Recently, the multi-factor fertilizer products NPK Van Dien 6:12:3 or multi-factor fertilizers NPK Van Dien 10:7:3 are very good fertilizers for fruit trees, especially in the post-harvest stage. . Using Van Dien fused phosphorus products and Van Dien NPK multi-factor fertilizers helps to provide a balanced, complete, multi-, medium-, and micro-nutrients for longan, litchi to restore roots and branches and leaves.

Instructions for fertilizing longan and litchi in the post-harvest period This year’s lychee fruit season is very good, so it is necessary to increase efforts to take care of litchi early, while the longan trees bear fruit unevenly, even many trees do not bear fruit, so the care of this year’s longan must be specific to each tree. Non-flowering longan and litchi trees: The longan and litchi trees this year do not flower if this year is not well taken care of, next year will certainly be poor in harvest. To prepare for the fruiting season in 2022, with the trees that do not bear fruit this year, around June and July, corresponding to the annual fruit collection time, still cutting, pruning and weeding as every year. At the same time, apply deep fertilizer with 3-4 kg of composted organic fertilizer and 3-5kg of Van Dien fused phosphate fertilizer, in order to provide phosphorus and secondary and micronutrients, part to prepare and accumulate nutrients. for the next crop, the nutritional compensation for the recent overgrowth of leaves is too strong. The litchi trees, longan trees are bearing fruit: Immediately after collecting the fruit, it is necessary to immediately start weeding for the trees: Prune toothpicks, pests, overhanging branches, branches under the canopy … at the same time, fertilize the trees, hoe around the canopy and then fertilize. The amount of fertilizer for each root is about 5-10kg of composted organic fertilizer, 5-7kg of Van Dien fused phosphate fertilizer and 3-5kg of Van Dien NPK multi-element fertilizer (5:10:3, 10:7:3. ..). Mix well with the soil, spread it in the canal and fill 2/3 of the trenches, grass cabinets, and garbage to keep the stumps warm. If the soil is too dry, it needs to be watered to keep the roots moist. Based on the time of harvest and the health of the tree, it is necessary to affect the summer or autumn buds. The early fruit trees in June, July, after weeding and fertilizing will give summer buds. Fertilizing for the autumn fortune: Locusts are formed on the leaf axils of summer buds (for early-harvesting plants) or grow from the leaf axils of fruit branches with late-autumn plants. This is the fruit branch of the next year’s longan and litchi crop, so it is necessary to pay special attention to adjusting fertilizer so that the harvest ends before November every year. Apply fertilizer to promote autumn buds in September and October after the summer buds have matured (into the leaves), apply 2-3kg of multi-element fertilizer NPK Van Dien 10:7:3 in combination with felling, pruning and removing branches. pass) in the canopy. Apply fertilizer to promote the collection of 2-3kg of multi-element fertilizer NPK Van Dien 10:7:3 in combination with felling and pruning. Photo: Vadfco. Note, only fertilize the autumn buds for trees under 15 years old, showing signs of lack of fertilizer, poor growth (showing yellow-green leaves) or late fruit trees in August, September. The growth pattern of the tree and the yield of the harvested fruit with more or less fertilizer application. If the weather is dry, it must be combined with watering to help the plants recover quickly and develop early autumn buds. When the buds are collected evenly, it is necessary to spray insecticides to ensure that the buds come out evenly and abundantly, the young buds grow well and are strong enough to make fruiting branches next year. Usually on an old fruit branch, there are many new shoots. When the young branches have enough leaves, it is advisable to trim away the weak, weak branches, leaving only the strong, fat huts to keep as the mother branch for the next crop. In the winter months, do not water, fertilize, create all conditions for the tree to “barren”, inhibit the formation and development of winter buds. By applying Van Dien fused phosphate fertilizer and Van Dien NPK multi-factor fertilizer right after fruit collection to create many vigorous autumn branches, combined with inhibiting winter buds, spring when the weather is warm and humid, longan trees , the fabric begins to spring up. Only apply fertilizer to catch flowers for longan and litchi when flower sprouts appear in the axillary leaves of the branches, the amount of application is about 3-5kg of multi-factor fertilizer NPK Van Dien 10:7:3 or 10:10:3, buried. Seal the manure, then water it to stimulate the buds and flowers. Fused phosphate fertilizers and specialized multi-factor NPK fertilizer products for Van Dien at the same time provide a full and balanced supply of essential nutrients for longan and litchi trees, helping them to grow strong and resistant to external conditions. Under unfavorable circumstances, especially during the winter break, litchi trees balance growth with development, creating bountiful fruit seasons.

In any season of the year, the rose garden on Ms. Hien’s terrace blooms brilliantly. Can’t believe I can grow a beautiful flower garden In the afternoon, the sun went out, Dinh Thi Dieu Hien (living in District 11, Ho Chi Minh City) went up to the terrace again, immersed in the blooming rose garden, emitting a sweet scent. She said, up to now, she does not believe that she can grow such a beautiful rose garden. Because, the rose is a species suitable for temperate climate while HCMC is hot all year round. Hien said, she grows flowers because she loves and wants to beautify her house. So, when she saw that the balconies of many houses abroad were covered with roses, she dreamed of being able to grow this flower on her balcony. The flower garden has many different types of domestic and imported roses. That passion burned even more when she noticed that there was a movement to grow infrared flowers in Vietnam. Unable to wait any longer, she ordered a pot of roses from Phu Tho province to plant on the balcony of the house. “Red is very red. Must understand to take care of flowers. At first, I only planted persimmons in the balconies. However, here the tree does not have enough sunlight, so it is very weak, giving small, few flowers. So I put the flowers on the terrace for the plants to have enough sun and then brought the plants back to the old location, “said Hien. To plant such a beautiful flower garden on the terrace, Hien spent 3 years tinkering and experimenting. Moving the trees constantly made her tired and came up with the idea to turn the empty terrace into a flower garden to grow roses. However, when moving the tree to the terrace, she had to face the reality of hot weather, burning hot sun. In order for the plant to grow well, for beautiful flowers, she tinkered and found her own flower care formula. She said: “In the balcony with little sun, every day I just spray the leaves thoroughly in the morning. If it’s too hot, in the afternoon I just mist the leaves and spray before 5pm. The fertilizing regime also reduces high-protein fertilizers because less sunlight and more protein are easy to cause diseases. In the early years, she fell under stress because the flower growing failed continuously. “When planted on the terrace, the tree will get more sun and wind. Therefore, I watered twice a day, sprayed the leaves thoroughly in the morning and afternoon. In addition, I also pay attention to shading the pot with straw, pine bark … or growing vegetables and short-rooted flowers that both provide oxygen and cool the pink roots,” she added. Insomnia, awake because of flowers She said, in order to accumulate that experience, she spent sleepless nights just thinking and trying to make the garden live and bloom beautifully. In the first year of planting flowers, Hien almost always fell into a state of stress, stress by investing effort and money, but the tree did not sprout, give buds, bloom. Up to now, she has found her own secret to being able to grow all kinds of roses on the terrace of her house. Not giving up, she joined and learned from rose-growing associations and groups. She applies that technique to her flower garden and then spends time researching and gaining more experience from the fact that she takes care of flowers every day in the garden. Finally, after 3 years, she understood and grasped the characteristics of roses. Even, she has accumulated experience and techniques for growing roses on the terrace in the year-round hot weather of Ho Chi Minh City. After 3 years, she has covered her empty terrace with many kinds of roses for bright, fragrant flowers. She shared: “Hong loves the sun, in addition to the need for 3 hours of sunshine or more, it also needs the following factors: first soil, second pot, three varieties. Fertilizer is just the last addition. My soil composition consists of: 25% finely ground alluvial soil, 45% vermicompost, treated coir, smoked rice husks, bat manure and perlite. She also noted that the mixing of the soil must ensure that the soil is loose and well-drained. Because persimmons must be planted in pots, placed on the terrace, the pots also have certain criteria. Ms. Hien’s experience is that it is necessary to choose a good drainage pot, even after buying it, she also drills more drainage holes. To maintain the flower garden, Ms. Hien spends a lot of effort and time taking care of it with her own techniques. In addition, Ms. Hien also listed techniques for fertilizing plants. She always spends a weekend to fertilize and spray her flower garden. Up to now, Ms. Hien has in hand the technique of fertilizing roses according to a specific formula and experience. One of the factors for the tree to flower wrongly and continuously is the pruning technique. These techniques include: choosing a fertilizer that provides adequate nutrition for each stage of the plant, when fertilizing, it must be applied 2-5cm from the wall of the pot, 3 days before the flowers die, apply fertilizer to provide a lot of phosphorus to stimulate the roots. For the next sprout, after cutting the flowers, fertilizing provides a lot of nitrogen, applying oil cake in combination with watering the roots with seaweed… Especially, she grows flowers without using drugs and chemical fertilizers, but only using natural products. In particular, Ms. Hien grows completely organic roses and does not use any drugs or chemical fertilizers. When it comes to dealing with pests, she only uses neem oil, orange essential oil, etc. Therefore, her flower garden is extremely safe for family members. Even now, even though she is pregnant and nearing her due date, she still goes to the terrace, goes to the rose garden to see flowers, and takes care of the plants every day. So the flower garden is not only beautiful but also very safe. Hien’s family members are very fond of flower gardens. Currently, the flower garden on the terrace of Ms. Hien has many varieties of Vietnamese roses such as: Sapa ancient roses, Hai Phong ancient roses. There are also many beautiful and attractive infrared flowers such as: Soeur Emmanuelle, Juliet, Mac Spice, Angela, Masora, Mon Coeur, Friendship of Strangers, Purple Ice Cream, Corail Gelee, Katherine Blue, Amandine Chanel , Pope John Paul II, Double Delight… Even though she is pregnant, Hien can still go to the flower garden to look at the flowers and inhale the sweet fragrance of the roses. Ms. Hien further shared that, in order for roses to have beautiful and regular flowers, tree pruning occupies an extremely important position in the care process. For each type of persimmon, she has a specific way of pruning branches. In addition to roses, Hien is currently growing some fresh vegetables and fruits to add to her menu every day. She shared: “When the persimmon lines are cut, keep watching from the flower to 5-6 axillary leaves, choose the axillary with the most beautiful sprout eye to cut. The bush line should be cut 2-3 axillary leaves, inflorescence line, cut below 4-5 leaf axils. “Cut off all the bad branches, the tree is easy to give root sprouts with long bunches of flowers. If you want the tree to bloom at the same time, when you cut the dead flowers, you should cut them only once, if the flowers bloom before they fade, just leave them on the tree and wait for them to bloom. After finishing, cut it,” added Hien. Posts: Nguyen Son Image: Characters provided

Bitter bamboo is the earliest of all types of bamboo shoots. In the high mountains all year round, there is white mist where bitter bamboo shoots grow. Thick fogs are dense early in the morning, thin late afternoon fog always keeps the forest cool and grows shoots of bamboo shoots. It is known that the bamboo shoot season is due to the acacia tree along the stream. When seen under the leaf armpits, the tips of the twigs sprouted young, purple, shiny buds, they called each other to look for bamboo shoots. The young tree buds signal that the bamboo shoots in the forest have sprouted. Every year the buds on the tree grow more, that year the rain will be favorable and the bamboo shoots will be more delicious. The tree grows only along streams, bitter bamboo shoots like to live in high mountains. Who found that predestined relationship? I do not know. Hearing the old people say, grandparents in the old days took a lot of work, sometimes even their lives could find the tubers, the fruit that could be eaten, the leaves, the plants that could be treated. The forest is immense, there are many mysteries. Every time you go to the forest, do not just rely on the available experience, you must know to find for yourself valuable experiences, to tell your neighbors, to tell your children, to your children. If you want to get bamboo shoots deep underground, you must find by experience. Digging out the dry leaves around the bamboo base, seeing where the soil was pushed up, the meniscus was stretched and ached, and there was a rough crack like the roots of a tree, there was bamboo shoots. The first shoot must be enjoyed immediately. At this time, bamboo shoots have not yet grown from the ground, so it is very sweet. Peel off the pale purple skin, white bamboo shoots. Get the packet of grilled chili salt available from home and place it down on the dry leaves for dipping. Perhaps only bitter bamboo shoots can be eaten raw, because they do not taste as bitter and spicy as other types of bamboo shoots. There are times when people find bamboo shoots according to the traces of the pineapple. Bamboo shoot is the most favorite dish of the mountain. Just sniffing is to know where there are sleeping bamboo shoots. But the bamboo shoots in the depths and the piles are small. It gurgled from night to morning but still had not seen the bamboo shoot. In the morning people also go to the forest to look for bamboo shoots. You just need to find the holes and dig a few holes, dig a few more spades to have bamboo shoots in your boss. Anyone who knows how to think will leave it for a piece of bamboo, whoever greedily will take it. Poor uncle so hungry, sitting in the cave looking regretfully, waiting for someone to go to run out to gnaw some remaining bamboo shoots. When the new rain brought the thunder of the beginning of the season, thundering running along the roofs, running across the rice fields, the bitter bamboo shoots in the forest reaching out to sprout the soil. The sound of thunder calls bamboo shoots up. The sound of thunder transmits soul, personality, and bitterness. Jagged shoots to grow. The earrings are like ears pushed up and listen to thunder and rain. Then, the sweet taste of bamboo shoots will gradually turn bitter. At first it was messy, then bitter, crispy and bitter. Bitter taste makes us feel hungry when a certain season of bamboo shoots away from the mountains and home. There are also people who do not like the bitter taste, they already have young acacia leaves. The acacia leaf is a type of acrid leaf, perhaps the most acrid among the acrid leaves. Pick up the bunch of leaves, roll them around the bamboo shoots, dot in the bowl diagonally, bring them to your mouth to chew. Seeing that the bitter taste is only as thin as the afternoon dew, the crispy sweet taste like bamboo shoots mixed with the pulp of the acrid leaves, the bitter taste of the wild chili, the numbness of the tongue of the cocoon fruit, the salty taste of salt. . Eating bamboo shoots in a warm dinner and seeing all the sweetness, bitterness. This morning, passing the stream Waiting for Cage, I suddenly stood in awe in front of the acacia tree. Each bunch of young, shiny, purple leaves have turned blue ever since. Bewildered at the top of the branch, shy under the leaf armpits, like bunches of bright yellow buds like drops of honey flies drinking from the sun. Hidden in the canopy of leaves and leaves, there have been a few hours of early summer calls. Just a few more days, the drops of honey will bloom into hundreds of brilliant yellow flowers. At that time, the bitter bamboo shoot season also passed …

One of the steps to graft the branches to renovate citrus varieties. Photo: H.Tien. Steps taken before transplanting – On the garden of sour grapefruit varieties or low quality indigenous grapefruit varieties (real grapefruit): Choose plants that are 3-7 years old, grow well, be free of pests and diseases, especially have no stem borers, no germs. leaf rot yellow leaf disease, greening leaf yellowing (Greening) and Tristera’s disease. Then, cut down the entire canopy to the stem or branch with a diameter of ≥ 2cm, leaving only the ends for eye grafting in the position of the stem with the color of the cake, the same size as the top of the chopsticks. The number of branches left for grafting should be arranged evenly 0.5 m on the tree canopy as a mesh. Grafting season can be carried out all year round. It is best to graft in 2-3 months and 9-10 months. Note, stop watering and fertilizing on real plants 15-17 days before grafting; do not extract and graft trees into the rain. – On the mother Ruby grapefruit tree, choose a tree that grows balanced and free from pests and diseases as above. It is advisable to choose mother plants grown in a net house to prevent insects, to avoid completely dangerous diseases such as Greening and Tristera. Then, select branches under 1 year old, have rounded stems and are tilted from horizontal canopy upwards, then remove all leaves, leaf stalks attached and remove the tip at the position of the stem color of the cake. Continue to cut the branches to divide the seedling into branches containing 4-5 leaf axils, 7-10 cm long and have a flat color. Technique of grafting the branches (also called grafting, grafting wedge) – At the base of the seedling segment, use a specialized knife to cut 2 opposite beveled slices, 2-2.5 cm long to remove 2 stem parts at the base of the seedling and open a wedge-shaped composite end. At the predetermined graft head on the phylogenetic tree, split a line 2.5 cm deep at 1/3 of the tip diameter to open a grafting mouth, insert the wedge-shaped graft head into the grafted mouth that just opened above. Ruby grapefruit has been successfully grown in our country. Photo: TL. Then, stretching and twisting the nylon strip, twisting the rope, then wrap 5-6 rounds tightly around the graft. Finally, pull the grafted plastic strip flat, completely covering the seedlings and grafting spots, so that rain cannot penetrate the grafting marks and keep the seedlings from dehydrating. After about 10-15 days (depending on the season), the grafted eye will sprout. Must eradicate in time the sour grapefruit sprouts growing outside the grafted eye. Note choosing self-destructing polypropylene tape. – In addition to improving the seed by grafting wedge into the branches mentioned above, it is also possible to graft wedge into the cross section of the branches of much larger size, or graft windows, small wooden eyes along the trunks. tree, trunk. However, these grafting methods have certain limitations, compared to the method we introduced in the previous section, such as, small eye grafting with wood, only taking the seed eyes open, the tree will grow long. , time for exploiting business results is slower … Take care of real plants after grafting Spraying to draw amulets when the eyes are like sprouting is 0.5-1.0 cm long. Except for red spiders, soft aphids, leaf hoppers and plant diseases, during the period when eyes are like spreading branches and canopy. Fertilizer for 1 root: 0.2-0.3 kg NPK 13-13-13 + TE, fertilize periodically once a month. Foliar fertilizer sprayed evenly 7 days / times. Decomposed chicken manure 20-30 kg + 2-3 kg of microbiological organic fertilizer, fertilizing when the grafted eye has reached about 15 cm long branches. After 1-2 years grafting and improving, Ruby grapefruit trees have been exploited for business. From this stage on, the steps to take care and control pests and diseases are similar to other current pomelo seedlings. Ruby grapefruit is one of the elite citrus varieties of Thailand, which has been imported into our country. The variety has the advantages of strong growth and development, beautiful fruit shape, good resistance to pests and diseases, red fruit, thick and thick pods, fragrant sweetness, no seeds … Grapefruit is equivalent to or slightly better than that of our country’s green skin grapefruit. , depending on farming techniques and ecological conditions. Ruby grapefruit tree is easy to distinguish from other grapefruit varieties thanks to the small leaves and branches, smooth hair.

Having a passion for planting trees and seeing that on the hot terrace, she decided to cover the green for shade. She went to the online tree planting associations to learn from experiences. “I chose to grow melons because my family likes to eat and this plant gives fruit fast,” she said. A corner of the garden on the terrace of Ms. Ngoc Anh. At first, Ngoc Anh bought seeds at the supermarket and planted about 20 foam boxes, watering them manually. But when she gave the fruit, she found that the melon was very light and could only be used for drinking water. Besides, the manual watering took her a lot of time. “In the morning, I struggled on the terrace to water, pollinate flowers… In the afternoon, I ran home from work to pollinate and was scolded by my family for being too“ mortal ”, she said. After that, Ms. Ngoc Anh decided to find different varieties of melons (Vietnam, Japan, and Korea) to sow seeds. At the same time, she also designed the rig to save area and labor effort. “I consulted on the internet, then measured and bought materials and asked my husband to help with the assembly. Because it is self-made, the cost is quite cheap and in just about a week, the staging for planting trees has been completed ”. “If you plant plants in a foam bin, the water that flows out will seep into the terrace floor. A few seasons later, thanks to the suspension system, we overcame this situation while saving area and time for watering and fertilizing. The garden is always clean, the tall truss system looks more beautiful, ”she added. Currently, her terrace garden has more than 100 pots of melons of all kinds such as melon, green melon, watermelon … Each type she planted 2, 3 rows to eat not to get bored. In addition, she also took care of dozens of pots of roses, purple corn, bitter melon and fruit trees, grapes, apples … In addition to fruit trees, she also planted a lot of roses. “I usually spend 2 hours in the morning taking care of the garden. When it comes to the stage of pollination and fruit hanging, I have to get up earlier because I am afraid I will not have time to go to work at the company “, she said. “The garden does not have many bees and butterflies and many different fruits, so I am afraid of bees, butterflies pollinate all the time, so I self-pollinate. After that, I wrapped it to avoid the golden flies, then left hanging … “. In the first few cases, Ms. Anh shared, regarding fertilizers, she used chemical fertilizers. After that, she learned how to grow organic. Currently, she composts fish manure by herself, banana manure (for sweet fruits), custard-apple fertilizer … After that, she runs it on the watering system so that the plants can be absorbed regularly and save time on fertilizing the garden. “I think the matter of nutrition and the way of care will determine the outcome. Nutrition for plants in each stage will also be different, ”she said. In order to have large, well-rounded melons, Ngoc Anh has a secret that is to focus on collecting pollen for melons when the tree has grown from 10 to 12 leaf axils, usually keeping only one fruit on the tree. This season is the main season so she planted more than 100 melons, normally she sows about 40, 50 trees. “Every half a month, I grow new varieties of melons to have melons to eat all year round. Depending on the variety, about 60 to 90 days can be harvested, ”she said. Vegetables and fruits harvested from the garden were too much, the family could not eat them all, Ms. Ngoc Anh brought to her friends, colleagues, relatives … At weekends, she spends all of her time in the garden weeding and cleaning. Her husband supported his wife to plant trees, but when he saw that she was too passionate about the garden, he joked: “Wife cares more about trees than husband.” “You want me to plant less to have time to relax and rest,” she added. See more pictures of Ms. Ngoc Anh’s garden: The garden has all kinds of melons. The results obtained after each melon crop. Ms. Ngoc Anh also planted dozens of persimmons Purple corn and suffering.
