If they haven't already, weeds will soon be sprouting throughout the yard and garden. Taking some time to learn to identify these intruders will make control easier.

Learn to differentiate weed seedlings from desirable plants when they are small so they can be quickly eliminated from the garden. This website from University of Arizona Cooperative Extension U of A Photo Library has photos of common weeds at different stages of growth.

Clever Gardening Technique

Water Deeply to Prevent Salt Burn
Our water quality influences how we irrigate landscape plants. Some water sources, including well water, can contain high salt concentrations. These salts are deposited wherever water stops penetrating through the soil. Frequent shallow irrigations allow salt to accumulate in the plant's root zone. Roots absorb salt and the plant develops "salt burn." If shallow irrigation continues, the plant may die. Follow the 1-2-3 Rule to ensure water soaks down through the root zone with each watering. Water should soak 1 foot deep for shallow-rooted plants (annuals, perennials, cacti, succulents, ground covers), 2 feet deep for shrubs and 3 feet deep for trees.
