Caring for fruit trees during the rainy season

Mangosteen garden of Gia An farm, Dong Gia Nghia ward has a sturdy main branch support system.

Gia An mangosteen farm in Dong Gia Nghia ward meets GlobalGAP global good agricultural production standards. From July to September, the peak of the rainy season is the busiest time at Gia An farm. Because this is the time when regular tasks such as weeding, fertilizing, pruning branches and harvesting fruit are performed. This year, the garden of more than 10 hectares has a good harvest, with many fruits of good quality, bringing much joy to the garden owner.

According to Mr. Tran Quang Dong - owner of Gia An mangosteen farm, his family has developed mangosteen orchards for over 20 years. His experience in protecting fruit trees during the rainy season is to take care of and protect the trees before, during and after the rainy season. In addition to planning plots and planting areas to avoid wind directions, he is also interested in the system of windbreaks around the garden and fields.

When the tree started to enter the business stage, he used a system of small, sturdy iron pillars to support the main branches of the tree. The family pruned the branches and created a canopy in a cone shape to limit the wind. The rainy season is also the time when Mr. Pham Vinh San, Dak Sak commune, is very worried because his family's 4-hectare avocado garden is prone to fruit loss, especially for booth avocados.

Mr. San said that he limited the fruit falling due to heavy rain by applying balanced fertilizer. The next step is to take care of the soil and nutrition. He increased the porosity of the avocado soil by applying organic fertilizer combined with chemical fertilizer in the right dosage. On days of heavy and continuous rain, he often visited the garden to dig drainage ditches for the trees in low-lying areas.

Thanks to proper care, especially during the rainy season, around October - November, his avocado garden is ready for harvest and produces consistent, good quality fruit, which can be sold at competitive prices.

According to the provincial agriculture and environment department, during the rainy season, farmers should prune fruit trees to keep them airy, cut off ineffective branches such as overhanging branches, branches growing in the canopy, branches close to the ground, branches with pests and diseases; cut off the top to limit the height of the main trunk to minimize the creation of large resistance when encountering strong winds, making the tree susceptible to breakage. Farmers tie the tree trunk and large branches in 3 directions to limit falling, especially for trees with many fruits, large fruit weight such as durian, avocado...

For fruit-bearing trees, if it is time to harvest, you need to proactively harvest early. If it is not yet time to harvest, anchor large fruits, tie branches, and prune some of the fruit on the bunch to avoid collisions that cause damage or fruit drop.

In particular, the agriculture and environment sector noted some remedial measures after being affected by storms and tropical depressions. Specifically, farmers dug trenches and focused on pumping water out of the garden quickly.

Saw off broken branches or leaning trees, and clean up the fields and gardens. At the saw site, use lime water or copper-based fungicide solution to brush into the saw cuts to limit the harmful effects of fungi penetrating into the branches.

To restore the health of crops, farmers need to increase the use of organic fertilizers and foliar fertilizers and limit the use of chemical fertilizers.

Orchards with young fruit or fruit in the development stage should spray foliar fertilizer containing Ca, Cu, B, Zn to avoid cracking. If the tree is loose at the base, the soil needs to be compacted, then you can water with fungicides such as: Metalaxyl + Mancozeb, Fosetyl aluminum or Trichoderma preparations to fight harmful fungi, water the base 2-3 times, 20-25 days apart to prevent and treat root rot...
