Fertilizer for aspen trees
We planted many 1 to 2 inch caliper aspen trees in Grand Lake last spring. These are field gathered trees that came wrapped in burlap. In the new holes we used one-half native soil and one-half planting mix. We did not fertilize last year. Is it okay to fertilize this spring, how often and what should we use? Thanks.

The fertilizer requirements for woody plant are low during reestablishment and high amount of nitrogen can be harmful to root establishment. I have included a link to a master gardener note that that explains the science behind planting trees and give some recommendation for watering and fertilizing trees when planting. If you have any other question feel free to give me a call at my Kremmling Office 970-724-3436.
Thank you. Brian
