Trees are terrific! Can anyone argue with that? Well, I guess I should add a caveat to my statement, “MOST trees are terrific!” There are invasive tree species out there that are the bane of many people’s existence, including mine, like Tree of Heaven (Ailanthus altissima), Norway maple (Acer platanoides), Mimosa (Albizia julibrissin) and Callery pear (Pyrus calleryana), to name just a few. And some trees are more terrific than others. Trees native to your specific area are generally better than non-natives, although if you live in an urban area you may need some non-invasive, non-native trees to withstand road salt, the urban heat island effect and the other tough growing conditions found in urban areas. Trees like Goldenraintree (Koelreuteria paniculata), Japanese tree lilac (Syringa reticulate) and Japanese Zelkova (Zelkova serrate) will grow well under tough conditions, yet not grow uncontrollably like an invasive.
Spring is a great time to plant trees, but you need to make sure you’re planting them in the proper site, with the proper techniques. Check out the TreeVitalize program website to learn all about proper tree selection, siting, installation and maintenance – http://www.treevitalize.net. Plus, if you live in certain parts of Pennsylvania you can download a coupon to save $15 off the purchase of a tree at participating nurseries. Municipalities and non-profits can even apply for grants to help defray costs on bulk tree plantings.

I live in a city center, surrounded by a lot of pavement. In such situations adding tree canopy cover is essential. Trees provide us with cleaner air and cleaner water, shade to lower heating bills and make sitting outside on a hot day more enjoyable, and aesthetic beauty. There was already a Japanese maple in my backyard when I purchased my home, but I added a native Eastern redbud tree too. It has grown a lot over the last three years, even given the poor quality city “soil” and is just plain beautiful in the spring with its pinkish-purple flowers. The flowering dogwood in front of my house provides food for the squirrels (they love to eat the fruits, sometimes to my chagrin) and blocks some prying eyes from being able to look into my living room window. Trees do so much for us!
