I have recently purchased several acres of
land (!!) that's mostly going to be for growing things. It has a cell tower near the north edge of the property. I'd like to plant
trees that will help obscure the tower as well as possible. Since we're talking about the north side, shade isn't going to be a big issue. My criteria are (1) fast growing, tall final height (so fruit trees are mostly out), but not overly short-lived, (2) ideally productive of food or other useful products, and (3) not going to negatively affect the growth of other plants nearby. I'm in Iowa, where we have hot summers and cold, snowy winters. Below are some of my ideas -- I'm very curious about other suggestions people might have.
1. Cottonwood. These trees are very fast growing and I like their appearance. They don't produce usable crops that I'm aware of. I think they may draw so much
water that things nearby might be affected.
2. Silver maple, especially the high sugar varieties. Fast growing but not as fast as cottonwood. I also like their appearance.
Should produce sap that could be used for maple syrup. I'm not aware of issues affecting nearby plants.
3. Walnut. Relatively fast growing, nice looking, produce a usable crop, but juglone is going to be an issue.
4. Stone pine (Korean or Siberian). I don't know so much about these trees yet but like the cropping potential.
5. Oak (various varieties). These are some of the natural trees for this ecosystem. Not the fastest growing. May be possible to plant varieties with usable acorns.
6. Shagbark hickory. Another
native for this ecosystem. Not sure about its growth speed. Possible usable crop.
7. Sycamore. Native to Iowa but not to this specific land. Fast growing. Nice looking. No known usable crops. No known negative impacts on other plants.
