Tilling Dirt at a Walnut Farm

Question

I have bought a small walnut garden/house in New Mexico. Do I have to till dirt? When? Which fertilizer do I have to use?

Answer 1

You don't have to till the soil, but it couldn't hurt if you have a large area. This article will help: https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/how-to-till-a-garden-tilling-your-soil.htm

Most trees do not need supplemental fertilizer but in general, if you are going to fertilize a tree, a fertilizer with a high N, a low or no P and a moderate K is best for non-fruiting trees (such as 30-0-10 or 32-3-10). If you are looking to get nuts from the tree, then you would use a fertilizer that has a moderate P (such as 30-10-10).
