Maintenance Haphazard maintenance results in wasting many gallons of water per year and defeats the purpose of establishing a water-efficient landscape. Other maintenance activities include weeding, fertilizing, mowing and pruning. Weeds grow well in the irrigated landscape areas and take water from desirable plantings. Eliminate or control weeds by hoeing, hand pulling or using a herbicide. After weeding, apply a mulch to these problem areas to control future weed growth.
Spring is the best time to fertilize turf.
Use a high-potassium fertilizer and follow the instructions on the package for the amount to apply. Excessive fertilization will cause unnecessary growth that will use more water. Taking a soil test every two to three years will identify soil deficiencies and determine fertilizer needs. Flexibility Gardeners in desert climates have a challenging assignment. Harsh weather, poor or salty soils, mixed irrigation methods, drought and poor drainage are factors the successful landscaper must master.
