What happens if I add too much fertilizer?
Excess fertilizer alters the soil by creating too high of a salt concentration, and this can hurt beneficial soil microorganisms. Over- fertilization can lead to sudden plant growth with an insufficient root system to supply adequate water and nutrients to the plant.
When should you not fertilize citrus trees?
Fertilization should begin in March and occur about once every 6 weeks through September. Allow the tree to produce and mature the fruit from October through February and refrain from applying fertilizer during those months.
What is the best fertilizer for citrus trees?
Most citrus growers in our area will use 13-13-13 fertilizer the first 3 years. The first 3 years the tree is to develop the root system. If fruit develops it is necessary to pick it off to allow for the root development. Trees 4 years and older can use 13-13-13 but 15-5-10 is the preferred fertilizer.
Can you over fertilize a lemon tree?
You can actually kill a tree if you apply too much fertilizer. Applying high levels of quick- release nitrogen can burn the roots when applied to the soil and can burn the foliage when applied as a foliar spray or drench.
How do I fix over fertilizing?
The best way to solve the problem of over-fertilization is to leach excess nutrients from the soil by using watering to slowly flush out the pot. (Your pot will need drainage holes for this.) To leach the soil, put your plant in a sink, tub, or outside where it can drain and give it a nice, long watering.
Can plants recover from over fertilizing?
Don’t worry, most over fertilized plants can be saved by a few simple steps. Remove visible fertilizer from the plant and soil, and leach away the fertilizer by allowing water to run through the roots. Then, remove damaged foliage and wait about a month before feeding your plant again.
How often should citrus trees be watered?

New growth also needs time to “harden off” before winter. Tender new growth is at risk of cold injury if it is forced late in the season, when plants and trees should be shutting down for winter.
Why is it not advisable to apply too much fertilizer on plants?
Too much fertilizer (applied too often or too much) can burn or desiccate roots, ultimately killing the plant. Too much fertilizer can also be harmful to the environment. But, fertilizers do a lot of good by providing macro and micronutrients that enhance the health and performance of plants.
