Treated Lumber and Alternatives in the Garden

Gardening in raised beds can be just the answer for would-be gardeners, who would love to grow their own vegetables and flowers, but lack the space or physical ability for a traditional garden.

Landscape plants should be pruned to maintain or reduce their size, to remove undesirable growth, to remove dead or damaged branches, and to rejuvenate older plants to produce more vigorous foliage, flowers and fruits.
