The spring season is generally considered the best time to plant, especially if planting is to be done on heavy loam or clay soils.

What is a tree plug?
Plugs in horticulture are small-sized seedlings grown in seed trays filled with potting soil. This type of plug is used for commercially raising vegetables and bedding plants. Plug plants are young plants raised in small, individual cells, ready to be transplanted into containers or a garden.
