Trees are a huge investment to make, so considering the right one for your region is a very important decision. You need to take into consideration the soil and especially the climate before just planting any tree. Be aware that oftentimes, many nurseries will provide tree options that might not even be suitable for your region. You’ll need to do your research before deciding on what tree to buy and plant for the Denver area. Colorado’s climate varies from North to South, East to West, so not every species is suitable for various parts of the state.
Before Buying Your Tree
There are many things to consider before purchasing a tree to plant. Trees can often outlive the homeowner, so keep in mind that the tree needs to be suitable for the future homeowner’s needs. Your decision can greatly influence generations to come!
A couple of things to consider are the size of your property and if there’s enough space for your tree to grow to its full height. Keep in mind that this doesn’t just mean the space above, but also the space below. The root systems can often grow two – three times the height of the tree. Determine the growth rate of the tree and also the form of the tree. Will your tree’s branches look more like a column, will they spread or will they have a more pyramid shape? This will help you determine the right space for your tree.
You’ll also need to pay attention to how much sunlight your tree will need to get. Make sure that there’s no overcrowding with trees that are already in place in your yard or neighborhood. You don’t want your trees fighting for sunlight, nutrients, or water.
