March and April are a good time to start thinking about adding some trees to your garden.

Trees are an investment that, if grown well, will add value and beauty to you landscape for decades to come. Trees provide shade, shelter for birds, sometimes spectacular spring blooms, fruit and good fall color.

There are several factors to consider when selecting a tree. Scale is probably the most important factor. Pay close attention to mature size when selecting trees. Large trees can exceed 50 feet, while small trees may reach maturity at 20 feet. Like Goldilocks you need to find the size that is “just right” for your garden.

Growth rate is a factor to consider. While fast-growing trees may seem like a good idea, they typically are more brittle, making storm damage a bigger problem.

If you are considering a flowering tree, think about fruit. Flowering trees that produce fruit can make a major mess in your landscape; are you willing to do the cleanup every year? Some varieties produce no visible fruit; others have fruit that politely stays on the tree through winter (persistent fruit), providing a food source for birds and requiring little cleanup. There is no right or wrong; just know what you are getting.

For larger spaces:

• Hackberry (Celcis occidentalis), native tree up to 50 feet in height, crown diameter of up to 30 feet; good shade tree, requires pruning in the early years, fast growing, good habitat for birds.
