Early Spring Fertiliser Applications
In September, trees are starting to awaken from their winter slumber. Make sure the trees are provided with everything they need to produce a strong flowering and good fruit set. The best strategy to accomplish this, involves putting the appropriate fertilisers on at the right time.
In early September, ground spread a complete compound fertiliser with a nutrient ratio of (14-5-15) or (10-11-10). This will provide the major nutrients (N-P-K) in an appropriate ratio and secondary (Mg-S-Ca) and micro-nutrients (Zn-B-Mn). This fertiliser will take 2-3 weeks to break down and enter the soil solution depending on rain and irrigation. This is a time when the tree is leafing out and forming flowers at a rapid rate.
Finally, consideration to the micro-nutrients Zinc and Boron which both are required in adequate amounts before and during flowering. These two micro-nutrients can be applied either foliar, prior to flowering, fertigated or mixed in with herbicide.
