Q.Mango tree
I have a mango tree not giving fruit for many years. What should i do and how
I suspect water deficit and/or nutrient deficiency.
Soil fertility and water management are vital for plant health, flowering and fruit development.
Irrigate during the dry season. Water a wide area not just near the tree trunk, water the entire area of the absorbing root zone which spreads as far as the foliar canopy and more.
Water deeply to wet the soil a minimum of six inches (15 cm), preferably to 10 - 12 inches (25-30 cm). Check this the next day, by digging down in a couple of spots to see how far the water infiltrated.
Fertilize at the beginning of rainy season, or according to local agricultural advise, with a complete organic fertilizer, composted/aged cow or chicken manure, or a chemical fertilizer like 15-15-15.
Mulch the soil surface to help retain soil moisture during the dry season.
