* 25% of the total N-P-K rate should be applied about 2-3 weeks after fruit-set. If at this time trees are showing deficiency symptoms, application can be made earlier.
** Applications should be made during the season until about 2 months prior to harvesting.
To induce flowering in citrus under tropical climate, where no temperature differences are noticeable during the day / night cycle, ceasing irrigation is recommended.
To prevent fruit drop and extend picking season it is recommended to spray 18 ppm 2-4-D combined with 1% – 2% Multi-K, with an appropriate surfactant.
