According to what plant scientists at the Missouri Botanical Garden (USA), the tiny purple-white flower that has just bloomed in their greenhouse has never been seen, at least by experts like them. In early May, Justin Lee, a gardener, was inspecting a group of Karomia gigas seedlings when he discovered a strange flower. This plant is related to mint and is native to Africa and is one of the endangered plants. Strange flower varieties Giống This flower less than 3cm long has pale purple ring-shaped petals, which slope down to form an arch connected to four white petals, with outstretched pistils. Mr. Lee said: “It doesn’t look like a mint flower. It looks like it’s upside down.” The mint family, Lamiaceae, usually has funnel-shaped flowers. Caregivers think the flowers may attract bees, butterflies and moths, but they may also be self-pollinating. Over the next few weeks, they expect more Karomia gigas flowers to bloom in the greenhouse, and instead of attracting insects, they will attract human hands trying to keep the species from extinction. When more flowers bloom, plants can cross-pollinate and have an extra chance of survival. Currently, only about 20 individuals of Karomia gigas are known in the wild in Tanzania. Roy Gereau, Tanzania project leader at the Missouri Botanical Garden, said it’s not uncommon for anyone to have seen flowers grow from this tree. Karomia gigas is a tall, straight-stemmed tree that can reach a height of 25 m, the branches grow about 13-14 m above the ground, making the flowers difficult to see. Karomia gigas is quite tall and is located deep in the forest. The tree is so rare that it does not have a common name in English, Swahili (the main language of Tazania) or the dialect of the area around the reserve where the tree was found. Of the more than 60,000 known tree species on Earth, Karomia gigas is among the most threatened and endangered in Africa. “As far as we know, there is no scientific record of the flower of this plant,” said Gereau. And now, when the trees bloom, conservationists believe they can keep them from disappearing. “In terms of extinction, this is a really, really good sign. We can make sure this plant doesn’t go away,” said Andrew Wyatt, vice president of horticulture at the Missouri Botanical Garden. There is still hope Growing this tree is a challenge. In the wild, Karomia gigas is highly susceptible to a fungal infection spread by insects. In September 2018, thousands of seeds were collected in Tanzania and brought to St. Louis, but only 100 seeds can be used for germination. The nursery also had to adjust soil texture, water availability and sunlight to mimic the East African environment in which the plants grew. Gardeners are finally able to grow the plants by letting the seeds germinate on wet paper towels (reducing the risk of infection), and then planting them in the potting soil. Currently, they have about 30 seedlings from seeds and one from cuttings. Creating a growing environment for this species is very difficult. “We’re debating whether they can bloom in a caring environment,” Mr Wyatt said. When there are only a few trees of this species left in the world, trying to save them and seeing them grow successfully is very emotional. “You will cherish every stage. They are like your children. You are like the housekeeper of these plants. You not only have a scientific connection, but also a love for them” – he Wyatt shared. Mr. Lee agrees: “They are like my children.” The flower helped scientists understand more about the plant, verifying it was classified correctly, and the shape suggested it was most likely pollinated by an insect. To date, they have not been able to tell if this flower structure is common to the species, or just a genetic mutation in the still young plant. “This single flower … may not be the usual flower form of the tree. This is the first flowering tree of fortune telling” – Mr. Gereau commented. The first flower was recorded. Most importantly, this helps ensure the survival of the tree. Botanists can take cuttings to propagate, but they will share the same DNA. Having genetic diversity will help ensure that plants can withstand harmful elements such as pests. “If crops don’t bloom, we have to depend on wild plants for seeds, and their survival is very low,” Wyatt said. While some species are able to self-pollinate, it is not clear whether Karomia gigas does. Mr. Lee tried pollinating before the flowers died, but said adding flowers from other plants would help create a new generation of plants that are genetically more tolerant. “I’ve chalked the flowers. But so far the self-pollination is still a big question mark. And this time we didn’t succeed. However, we have many seedlings left, if they bloom and pollinate. Cross-pollination is better for genetic diversity.” “Having a tree in bloom is a great start in a species recovery effort,” says endangered tree expert Emily Beech. Although not involved in the tree planting process in St. Louis, in 2016, Ms. Beech and Mr. Gereau and rangers searched for this tree in Tanzania. “When we got there, we didn’t see any sprouts in the forest, but the blossoming tree shows that there is still hope for this tree in the future,” she added. One step closer to reinvention Karomia gigas was discovered in 1977 in Kenya. When the last two trees here were cut down, scientists thought the species was extinct. Then, in 1993, several trees were discovered in Tanzania. From 2011 to present, Mr. Gereau and Tanzanian botanists have found more individuals in the wild. According to Mr. Fandey Mashimba, head of the seed department of the Tanzania Forest Service, about two dozen Karomia gigas trees still exist in the wild, in two forest reserves Mitundumbea and Litipo. These two reserves have the Miombo forest ecosystem – common in Central and South Africa. This is the habitat of wild animals such as gorillas, wild boar, wild buffalo and a small antelope called Dik-dik. While individuals studied in the native environment and one growing in St. Louis, their flowers are still a mystery. “We have a person in the nearest village to the reserve, he keeps an eye on them and will notify us when he notices the plants are about to flower,” said Mr. Gereau. However, when someone drove the long way through the forest and reached the tree, no flowers were found. “They’re in a reserve protected by the government, but a lot of people go there to get wood,” Mashimba said. The wood of Karomia gigas is compared to teak – a precious wood, so they have a high value. “We have trees that are still alive. We can make sure they don’t go extinct. Successful conservation of this species is possible. They are protected in Tanzania. We have a bunch of trees in the botanical garden. When we have enough seeds, we can store them in case.” Seedlings are cared for at the Missouri Botanical Garden, USA. Gereau said he does not want to transfer the plants yet, fearing they are too fragile to make it through the trip between the two continents, but his team will actively share knowledge with the Tanzanian government and botanists at the University of California, San Francisco. University of Dar es Salaam, which is conducting research on this plant. For now, a flower is a hopeful sign of what’s to come. The staff at the botanical garden at St. Louis was surprised when it quickly fell from the tree in less than 24 hours. “It withered and fell. I picked it up and used it as fertilizer,” said Mr. Wyatt.

Her family’s terrace covers an area of ​​100 square meters. In addition to planting 30 tomato plants for fruit continuously, Ms. Loan also grows cucumbers, melons, melon, bitter melon, vegetables and some fruit trees. Tools to plant Ms. Loan’s trees are old water tanks, foam barrels, old pots bought from the bottle yard. To keep the terrace clean and not heavy, Ms. Loan uses 20% of the cultivated land and 80% of the substrate (coir, ash, rice husks, manure, and waste) to grow trees. Ms. Loan started planting 30 tomato plants since September 2020. Trees are always fruitful. Sometimes, Ms. Loan harvested 40-50kg of tomatoes. She had to bring it to her friends and relatives if she could not eat it all. “After I harvested the ripe fruit, I applied fertilizer to the stump, 10 days after the fruit was ripe, I continued to harvest,” Ms. Loan said. She also planted strawberry trees on the terrace. Currently, the tree is ripe fruit. According to Ms. Loan, to have a green garden with high productivity requires gardeners to be experienced, diligent to explore and have a love for trees. In addition, growers must visit the tree every day to see if the plant is sick, has root rot or stem rot. “Caring for trees is like taking care of children. One day I did not visit, the tree was sick, ”said the woman from Vinh Long. Loan’s son is helping his mother to harvest ripe tomatoes. Melon trees and melon fruit. Loan said that to grow these fruit trees, it takes a lot of care and requires growers to have the techniques and characteristics of the tree. Her secret to growing a lush, fruit-bearing garden on her terrace is to use organic fertilizers and insecticides made by herself. As for insect repellent, Ms. Loan is made from waterpipe tobacco soaked with alcohol, incubated for 5-7 days and then watered for the plants. As for fertilizers, she uses soybean residue, spoiled bananas, eggshell, and kitchen waste to make compost. Using these types of waste as compost not only helps to provide enough nutrients for the plant, but also helps the tree produce more fruit, beautiful color, succulent, sweet. The next step in this woman’s rooftop gardening is to treat the soil before planting. “Treating the soil to get rid of germs is already 50% successful in gardening,” she said. Her soil treatment process is to mix soil, coir, ash, rice husks, manure … with powdered lime, eggshell, chicken manure, and dried soil, then plant trees. The grower must also provide the plant with sufficient water at all times. In addition, the gardener must apply fertilizer at the right stage of plant development, otherwise it will harm the plant.

1. How to plant roses with branches

1. Seasonality

Planting flowers by branches is actually the method of cuttings, and almost any time can be done. But the best time for cuttings falls between February and April and from August to October.

Illustration.

When cuttings in the rainy season are quite good, this will help less watering. As for cuttings in the dry season, water should be monitored regularly, always keep the soil moist, so that the new branches can take root and grow well. At the same time, when cuttings in the dry season, cuttings must be in a place with shade or must be made as a cover above.

1. Soil for cuttings

To cut rose branches, you should cut them in smoked rice husks, mixed with a little organic fertilizer such as decomposed cow manure or vermi-compost.

When dipping, it is necessary to cultivate the soil to relax and add more water to keep it moist. At cuttings, branches should be about 2 cm deep upright, not inclined.

1. Choose a variety of roses for cuttings

For the highest success rate, choose persistent persimmons such as wild persimmon, wild persimmon, but these varieties have not very beautiful flowers. The other types of persimmon, though not high in vitality, can still be cut.

In addition, there are persimmons that cannot be cut because the stem contains only a little starch, so the tree cannot afford to create new roots, so if cuttings will die.

1. Technique to choose cuttings

One of the important steps of growing roses with branches is choosing cuttings.

Choosing good cuttings is also an indispensable factor determining the success level of rose breeding. Ideally, you should choose the middle segments of the branches, roots or tops that are okay, choose those that are in the flowering stage, must be the twigs, not too old and not too young.

Branches used for propagation are straight branches, fresh and new within 1 year.

1. Cuttings techniques

After you have selected a healthy branch, about 20 cm long, use a knife or very sharp scissors to not crush the base of the branch, cut diagonally at an angle of 45 degrees. Cut away the dead flower buds, all the leaves and thorns from the lower part, and the upper part can be trimmed or left evenly.

Right after cutting, branches should be soaked in rooting stimulating solution and planted immediately to avoid bacteria penetration, killing rose branches.

1. Detail how to plant roses with branches

As mentioned above, planting roses by branches is the cuttings, which is a method of using a piece of the stem from the mother tree to be plugged into the ground, after a period of care, this stem will grow new roots and develop into a tree. new.

To cut the branches, dig a sufficient hole in the pot, loosen the soil and water it to keep it moist. Plug the rose branch to a depth of 1.5 – 2 cm, upright. Then, heap up the soil, squeeze the base so that the branches don’t wobble.

1.7 Fertilizer

After dipping, taking care of rose branches is not too difficult, just provide enough water, don’t let the soil get too wet to make the branches waterlogged.

When the branches start to produce leaves, some stimulants can be used to stimulate the plant to grow fast and bloom to large such as IAA or NAA, or some more popular substances such as Antonik or N3M, Super Roo.

2. Take care of roses

Location: Rose is a suitable plant to live in well-ventilated and sunny conditions. If there is enough sunlight for 8 hours a day, the tree will grow well and less harmful to pests, diseases, flowers and flower colors. also bright, beautiful, brilliant.

Watering: If you are planting in the garden ground you need to water 1 time a day, plant in a pot, water 2 times a day in the early morning and in the afternoon. Rose plants need enough water for the leaves to photosynthesize, if the plant is dry, it will appear red spiders harm the plant, yellow leaves and deciduous. You should limit watering at night because water will stay on the leaves, making the leaves more susceptible to fungal diseases.

Nutrition:

Nutrition: It is very important to decide whether or not your rose will produce lots of flowers, whether the flowers are large and vibrant or not, especially when you plant roses in pots. You observe the new branch if it has a dark purple color and a plump branch means that the tree is provided with enough nutrition, if the branch is thin and tall, it is necessary to add nutrients to the plant.

Land for planting: You should change your planted land once a year.

Fertilizer: Combine foliar fertilizer and root fertilizer alternately, once a month.

When the tree is at the top, the young leaves are supplemented with Dynamic seeds, bat manure around the base of the tree and watered to help the plant absorb nutrients well, mix NPK or agricultural DAP to water the leaves and stems.

When new plants sprout, flower buds add pink potassium, the flowers will have a strong characteristic color. But note that when the plants flower, do not fertilize because it will damage the flowers.
