The Garden Bug: Grow your own Christmas tree
By Brenda Weaver
A “Christmas tree” seedling should be planted outdoors in a moderately cool season such as early fall or late spring. Dig a hole the same size as the seedling's container; gently loosen the roots if the soil is impacted, then place the seedling and soil in the hole. Gently fill in and pat down where needed.
Water it weekly in its first year; after that, only water the tree during dry months or during a drought.
After the first two to three years you can start to prune and shear it. Harvest time will depend on what tree you've decided to grow, but it's best to cut it down in late fall when it is full of moisture.
This ensures your tree stays as green as possible during the holidays.
