Can I fertilize now? And what do we do for chlorosis?
We have a yard with 2- to 3-year-old trees and shrubs of about the same age. They haven't been fertilized since being planted except for a large tablet of some kind that was put in when they first went in and was supposed to last for a year or so (so we were told). Would you advise me whether I can still fertilize, or is it too late? Thank you very much.
Two of the trees look chlorotic to me -- light green leaves with the veins in dark green. One of them is a maple, the other we were told is a "Golden" something. Before we moved here, living in Fort Collins, we had a maple and aspens that were chlorotic and never could get them healthy despite all our efforts. Is there something in this area (Greenhorn Valley in Colorado at 6100 feet) we can do for these two trees? And thank you for your thoughts on either of these two situations.
