Nutrition
Apply extra fertilizer, such as 2 kg of K2O and 200 g of borax or palm per plant, in addition to the usual dosage. You can also try root feeding with a coconut tonic, such as 40 ml in 160 ml of water per palm every six months.
Soil pH
If the soil pH is less than 5.5, it's too acidic and you can add lime to correct it. If the pH is higher than 8.0, it's too alkaline and you can add gypsum. You can also try applying 1.3 kg of urea, 2 kg of single super phosphate, and 2 kg of potash mixed with 50 kg of farm yard manure per palm.
Irrigation
Ensure the soil is moist but not soggy, and water once or twice a week in the summer. You can also try mulching with green fronds to reduce evaporation and conserve soil moisture.
