The best time to plant fruit trees in the north is in spring.* In the south the best time is in fall.* Here in the Mid-Atlantic we fall in the middle.* Since it's already getting cold at night, with frost expected the next few nights, I'd say to wait until spring unless you are an experienced gardener.* Mid-September to the first two weeks in October is a good time to plant fruit trees in our area.

When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
