One very common question among citrus tree growers is “How much and how often should I fertilize my citrus tree.” John Panzarella, citrus tree expert, answered these questions and more at a seminar at the Kingwood Garden Center.
A timed release fertilizer is recommended for citrus trees such as Osmocote. There are different options available, including some which are organic. Using a three gallon pot as an example, John recommends, “peppering” the ground with a handful of the fertilizer granules.
To give the trees a jump start in the spring, supplement the time release fertilizer with one that is quick release and optimized for citrus trees in February
Q: Some say to add a pound of fertilizer for every year of the tree.
A: No. Simply spread an adequate amount around the base of the tree
- Don’t fertilize a tree after the primary growing season has ended. In the Houston area, do not fertilizer after September/October.
- Begin fertilizing for the new growing season in late February.
- If you can’t find a fertilizer formulated specifically for citrus, use an azalea fertilizer instead.
- The more water soluble a fertilizer is, the better.
