Most importantly, use a citrus fertilizer specifically designed for citrus, fruit, or nut-producing plants. These fertilizers have elements that fruit trees require. Also, citrus trees benefit from foliar-applied micronutrient Nutritionals that they crave. Some incorporate control-release fertilizer in their trees soil when planting or transplanting. Others do a top dress. No matter how fertilizing gets done, it is one of the three most critical steps in citrus tree success. The three crucial steps are food, vitamins, and water.
Fertilizing Citrus – Newly Transferred and Mature Trees
- First, fertilizing citrus can be done late February thru the first of October. At about six week intervals. Doing this will establish a full canopy on your citrus tree. Note: control-release fertilizers will be less often.
- Second, spread citrus fertilizer evenly under the tree. Go to the canopy edge, to assure all the tree roots are able to get the food the tree needs.
- Third, a slow-release citrus fertilizer high in nitrogen and potassium is what fruit trees look for most. Citrus trees are heavy nitrogen feeders. Potassium helps with fruit size and yield.
- Lastly, one little secret is that citrus trees benefit from 3-4 control-release feedings per year. The environment for citrus trees growing indoors is beneficial because they can feed year-round.
- Above all, consider applications of essential elements (a.k.a. vitamins). Consistent use of micronutrients will provide optimal conditions for trees to grow and thrive.
