How to Take Care of Avocado Trees When Flowering To Set More Fruits

How to care for avocado trees when flowering It’s always been a topic of great interest. Compared with other fruit trees, avocado is easy to grow, has wide adaptability, and is quite resistant to environmental stresses such as drought, wind, and poor soil. In addition to nutritional problems, avocado is also a fairly safe fruit, due to its thick skin, it is limited to worms or insects that sting, and pesticides are rarely used for avocado trees. How to make avocado trees when flowering receive the best nutrition and produce more fruit. The content of this article will help you understand this topic.

Fertilize during flowering, flowering and fruiting stages

  1. Flowering stage

After harvesting and having cleaned the garden, pruning the branches, applying 4-6 kg of SA and 0.5-1 kg of superphosphate, then watering to help feed the flowers.

Before the avocado tree flowers, it is necessary to add fertilizer to fertilize the avocado flower sprouts and help the tree recover quickly

Before flowering (padding stage): from 20 days to 1 month, apply fertilizer for the second time to restore and differentiate avocado flower sprouts with the following fertilizer content: 0.2 – 0.3 kg of Urea fertilizer + 0.5kg of phosphorus and 0.2kg of Potassium Chloride, in which, phosphorus we fertilize separately to avoid the interaction between phosphorus and Urea, we can mix Urea and Potassium chloride to apply 1 time. When flowers bloom evenly, we can spray Potassium Nitrate to help flowers bloom evenly.

For avocados that must shed leaves to flower, we must spray nutrient-regulating foliar fertilizers including Urea and KNO3 fertilizers at the rate of 3 – 4/1000.

During the flowering, pollination, and young leaf development, we begin to observe the plant, if the plant is sufficiently nutritious, just water it, if the plant lacks nutrients, spray foliar fertilizer.

When the plant sprouts flowers: do not fertilize the base.

  1. When the tree has fruited

After the fruits are peas evenly, as big as a chopstick, we apply the first fruit, including: 0.3 -0.5kg of Urea + 0.2 kg of Super Phosphate and 0.3kg of Potassium.

Fruiting trees need to be fertilized so that the tree has enough nutrients to avoid dropping young fruit

Single fertilizer, we should add lime and micronutrients with a content of 0.5 – 1kg of lime/year/plant, usually at the beginning of the rainy season and before the flowering period. Combined with the first fertilizer application when preparing to sprout and the third time after fruit set, we apply a combination of: 4 5kg Zinc Sulfate + 5-6kg Magnesium Sulfate and 6-7 kg phorate. These three types of fertilizers are very important for the plant: limiting deformed leaves that affect fruit set. In the 9th and 10th years, the yield increases, we fertilize from 20 to 30% of the amount of fertilizer just recommended above.

Currently, farmers prefer to use specialized NPK fertilizers rather than single fertilizers, then we need to note the following:

After harvesting: after cleaning the tree, the stump, we fertilize NPK with the ratio: 18:12:8 or 20:20:10, then water and keep the tree moist.

The upper part of the stem: use foliar fertilizers rich in organic and microelements, apply 1-2 times, each time 7-10 days apart.

When the flowers bloom evenly, reach, prepare to bloom: apply NPK to finish the flower + increase fruit set with the formula: 7:17:12 TE, then water evenly.

When the flowers have set, the fruit has adhered: apply specialized NPK with higher potassium content, recommended to use in the ratio: 14:10: 17 TE (Highland) in combination with foliar fertilization.

During the new fruiting period, do not overuse chemical drugs

The use of chemical drugs during the flowering period is not recommended because avocado trees are pollinated by insects. When we see that avocado has a phenomenon of rapid growth, cracking of fruit, we spray foliar fertilizer rich in calcium, calcium chloride to help fruit evenly, firm bark, higher quality and quality of fruit.

Making cotton to make avocado trees productive

Notes of engineer Ngo Van Huy – Bayer Vietnam Company – nutritional solutions for avocado trees when making cotton for high and sustainable avocado production.

There are 2 things to keep in mind

  1. Irrigation water

Avocado trees need low humidity but not too low, moderate, combine watering many times, maybe 10-15 days/time, for avocado trees in the business stage, it needs water from 150-200 liters/ root/time, watering 3-4 times/year.

During the flowering stage, the plant is very sensitive, needs just enough moisture, not much, if it is too much, it will cause flower drop and fruit failure.

  1. Nutrition

Balance the amount of NPK fertilizer, not too high, the buds will droop and the flowers will not come out, so the ratio: 2:1:1 or 1:1:1

Plants in the business stage should fertilize 3-4 times/year, 1 time in the dry season, 3 times in the rainy season, when fertilizing, we can create a basin or make a trench with a depth of 10-15 cm, then Then backfill with soil and water to help the roots absorb the fertilizer better.

Avocado trees in the business stage need to fertilize 3-4 times in 1 year

It is necessary to monitor regularly to detect and promptly handle diseases on avocado trees that cause low yield such as root rot, bark scab.
