How to Fertilize a Guava Tree

Guava trees can add both aesthetics and function to a landscaped area. Twenty feet tall at full maturity, guava trees can give a dramatic look to your front or back lawn while providing an abundance of delicious fruit as well. As with all fruit-bearing trees, guavas need to be fertilized in order to remain healthy in the long-term and continue to bear fruit. A good fertilization schedule and technique for your guavas can be designed in a few basic steps.

Monitor the age of the guava tree when it is first planted. Guava trees should not be fertilized at all when newly planted until new growth begins on the established tree; doing so may actually harm the tree. Therefore, delay any fertilization until the tree has sprouted new growth.

Apply fertilizer monthly when new growth begins. Fertilize monthly at a rate of 8 ounces per tree each month. Note, however, that if the manufacturer's printed directions recommend a different rate, you should follow the manufacturer's directions, since they are customized to deliver the exact nutritional needs of the tree you are fertilizing. Repeat this fertilization rate throughout the first year of growth.

Fertilize every other month during the second year of growth. Over the second growth year, gradually increase the fertilization rate to 24 ounces. After the second year, fertilize only as needed in response to nutritional deficiencies in the soil.
