If you don't have much of a green thumb, there's help. The City of Moscow Tree Commission is hosting workshops to help you take care of your trees. It's not as simple as you might think. These guys make taking care of your trees look like an art.
Wednesday is the pruning workshop. Yes, a seminar just to learn how to properly cut your trees, when to prune and how to prune, and there's even "small tree training". Interesting. It's September 7th.
The following Wednesday is for planting.
