Foliar Spray Phase:
After the tree produces 2–3 flushes of new growth, stop watering and do not apply additional phosphorus fertilizers (as it was already applied during the shoot formation phase). Only apply foliar sprays. Dosage may be adjusted depending on the tree’s vigor.
-
First spray: After the leaf matures (silky stage), mix 2–3 kg of Haifa MKP + 0.5 kg of 10-60-10 in 200 liters of water and spray evenly over the canopy.
-
Second spray: 5 days later, mix 2–3 kg of Haifa MKP + 0.5 kg of 6-30-30 in 200 liters of water and spray evenly over the canopy.
-
Third spray: 5 days later, mix 2–3 kg of Haifa MKP + 0.5 kg of 15-30-15 in 200 liters of water and spray evenly over the canopy.
-
Spray rounds 4 & 5: Continue spraying at intervals until leaves become brittle, thick, and flower buds begin to form.
For oranges and limes: Add 0.5 kg of Paclobutrazol 15WP (JUMBO F150) to 200 liters of water to further stimulate flower formation.
For pomelo: When leaves become thick and brittle, prune and defoliate old branches to promote targeted flowering.
Defoliation Phase:
Mix 1 pack of citrus flower stimulant + 1 kg of Multi-KZn (KNO₃ + 2% Zn) into 200 liters of water and spray evenly on the canopy. This will cause approximately 20–30% leaf drop.
Flower Bud Forcing Phase:
5 days later, mix 0.5 kg of 30-10-10 + 1 bottle of Growth Booster A+ into 200 liters of water and spray evenly on the canopy. Water the root zone thoroughly afterward.
Once 50% of flowers have bloomed, spray with 250 ml of BO 90 + 1 pack of BM chelated micronutrients.
After full bloom, spray with 250 ml of Seaweed CaBo + 1 pack of BM chelated micronutrients + 1 pack of Polyfeed 16-8-34 in 200 liters of water over the canopy.
Note: Combine foliar sprays with preventive treatments for anthracnose disease and thrips, which commonly damage flowers and young fruits.
