December is the beginning of the favorable season for durian trees for people in the Central Highlands and Eastern regions. Recently we have received a lot of questions related to the process of making durian flowers. The issue that people often worry about is whether their durian tree is strong enough to make cotton?
To answer this question for people, this article will guide people on how to identify durian trees that are qualified and can be made into cotton.
Tree age
Trees capable of making cotton must be 3-4 years old or older. Farmers should make cotton for trees that are 4 years old or older so that the tree has enough strength and avoids tree failure.
The tree has enough leaves
If a durian tree wants to make flowers, it must grow 2 or more buds before the tree has enough strength. Enough leaves and enough nutrients to make cotton. When the durian leaves have completely opened and the leaves have the color of banana buds (or banh te leaves), then proceed to ball the roots with Phosphorus. To ensure that the plant has the ability to bloom abundantly and bear good fruit, the leaves must have the following characteristics:
– Quantity: Must have at least 2 leaf buds (the tree has produced 2 buds and the leaves are completely old).
– Quality: Leaves are not diseased, attacked by pests or leafhoppers, leaves are healthy, thick and shiny.
– Healthy leaves. If the leaves are a bit weak, flowering will be easier, but you need to nourish the leaves carefully.
The tree is ready
Prune away toothpick branches and branches swimming in the trunk. Then spray and water the roots with fungicides (especially anthracnose) on the whole tree and around the roots, such as with some active chemicals such as Azoystrobin, Ascorbic acid, Citric acid, Hexaconazole, Difenoconazole,…
Note: Spray thoroughly and evenly wet the underside of the leaves, which is also where the pathogens of anthracnose and crab eye fungus remain.
People also need to treat moss, disinfect, and sterilize it properly before making cotton. After pruning branches, people use copper-based chemical products, cup 85 or Nano Cu or microbial products such as Forge SP containing actinomycetes streptomyces. People should spray the garden at noon, in sunny weather when the moss is dry, which is most effective. People spray the entire trunk, top and bottom of the branches.
Soil pH
The issue of soil pH is very important for plants, especially during the flowering stage. Therefore, if you want healthy plants and good flowering and fruiting, you need to check the pH regularly and maintain a stable pH level>=6. Lime can be used to balance the pH.
Pest management
Farmers need to check for harmful diseases such as stem borers, anthracnose, leafhoppers, aphids, sucking insects, etc. on the trees. Then spray for prevention with disease treatment products. Make sure the tree is free from diseases and healthy enough to make cotton.
Cotton making time
In the Central Highlands: Cotton making time usually falls in January and February of the solar calendar.
In the East: Cotton making time usually falls in November and December of the solar calendar.
At that time, it was dry, with little rain and favorable wind conditions for cotton production. There are two cotton making periods in a month (the beginning of the month and the end of the month). At that time, the plant flowers easily, flowers evenly, is strong and healthy.
Note: The above time for making cotton will not be accurate for all areas. You should consult gardeners in your area about the time and flowering time for more accuracy.
That’s an overview of how to identify durian trees that are qualified to produce flowers. Thank you for your interest. Wishing you a good harvest and a winning season.
