Q: Would you please tell me when you advise starting to fertilize citrus this year and what product you recommend.ย We live just south of Sunrise Drive โ not sure what the elevation isโabout 2,800 feet I think.
A:ย The first date for fertilizing citrus is in the January/February time frame. How much you use is dependent on the size of the tree.
To determine the appropriate amount it would be wise to check the publication โCitrus Fertilization Chart for Arizonaโ (az1671) that can be accessed through your favorite search engine on the internet at tucne.ws/h3r.
There are some products labeled as citrus fertilizer so you could look for them where you shop.
