How to Fertilize a Citrus Tree
Use a fertilizer specifically for citrus plants, fruit or nut producing plants. These fertilizers have elements required for fruit production. It is also recommended to use foliar applied micronutrient nutritionals that citrus trees crave—they provide additional "vitamins" your trees will love. In addition to Citrus tree micronutrients the use of Calcium and Boron can be used at bloom stage to encourage the tree to hold fruit and not drop their fruit otherwise known as Post Blossom Fruit Drop. GrowScripts has great nutritionals based on what has been proven in the citrus industry by growers research and universities.
Newly Transferred and Mature Citrus Trees
For the first three years of newly planted trees it is recommended to fertilize from late February thru the first of October about every 6 weeks to establish a larger, fuller canopy on your citrus tree. (Note: Slow release fertilizers like our Trivium 18-5-10 Slow Release will be less often. Just make sure to follow label directions.) Spread fertilizers evenly under canopy getting some out by the drip edge of the canopy, but also some in and around 4-6 inches from the tree trunk. Granular fertilizers can burn tree roots and cause issues if used to heavily due a lot of times to the salt content. It is recommended to use a slow release fertilizer high in nitrogen and potassium as that is what newly transplanted and established trees look for most. Citrus trees are heavy feeders and can benefit from 3-4 slow release feedings throughout the suggested fertilizing months above. Along with fertilizing with a product such as an 18-5-10 Slow Release additional applications of Essential Micronutrient Nutritionals are important to get the Citrus tree what it needs in the form of elemntal feeding. Citrus trees are able to take up nutrients by the leaves and GrowScripts has brought to market the right foliar nutritionals that are chelated with higher grade materials and gluchoheptonate, which is a much better chelation process for the plnts as they are better able to take up nutrients in this form versus EDTA and HEDTA.
