Your peach trees require fertilizer. This is about fertilizer for your peach trees. I'm Richard Skinner, owner of Hawkins Corner Nursery in Plant City, Florida. Peach trees are a very delicate piece of fruit, consequently, the fertilizing must be done properly. Existing peach trees require about one pound of fertilizer per year of age of tree, up to six or seven pounds, depending on your area of the country. Also, it needs to be applied about three to four times a year, again, depending on your climate zone. The fertilizer is number one, is nitrogen, the second number is phospherus, and the third number is pot ash. Along with that, which is very, very important, is your trace minerals, the different things that make the fruit taste good, make the tree grow good, not just fertilizer alone will do that. So when you fertilize, you want to make sure that you have the proper fertilizer for your peach tree. If you have a local fertilizer manufacture, they would be the best source to find the proper fertilizer, and your extension service office will tell you the proper time. Here in the South East, peach trees, the first fertilizing for peach trees is generally some where between February the fifteenth and March the fifteenth. Farther South you are, the earlier, the farther North you are, later. But in that four week window is when you do your first fertilizing for your back yard tree. This is Richard Skinner coming to you from Hawkins Corner Nursery about fertilizing your fruit tree.
