At this stage of the season, we are completing the flowering and fruit set, a process in which the tree spends a lot of energy (sugars, starch, water, nutrients, etc.). Now is the time to recover all resources used by the tree. Your avocado trees now need:
Fertilizer: Adjust nutrient amounts based on fruit load and the stimulation of new growth (next year’s floral shoots). Aim to make healthy leaves, fruiting wood, and strong roots.
Irrigation: Water is the basis of the photosynthesis process (energy for the tree). Increase the amount of water and/ or irrigation frequency.
Pruning: Control the height of tall trees, regulate alternate bearing, control regrowth, and remove “dead” wood. It is important to keep a good balance between reproductive and vegetative growth. Reduce sunburn by painting the branches with a mix of white paint and water. Remember to disinfect pruning tools between each tree.
Pest control: Monitor pest populations, such as persea mite, to evaluate need for control.
Mulching: Add mulch to improve conditions for better root growth.
