WATER-WISE GARDENING…When planning your water-wise garden, remember these seven basic principles:

1. Plant less lawn. Grass is the biggest water user in your garden. To be most water efficient, lawn should be planted only where it is functional, such as play areas. When possible, replace lawn areas with ground covers, low-water plants, and mulches.

2. Choose water efficient plants from this list. Your nursery has many familiar trees, shrubs, perennials, and groundcovers that you may not have realized were water efficient. Take this list with you to the nursery as a guide. Remember: theplants will need extra water for the first year or two until they are established.

3. Improve your soil. For healthy plants, use organic material such as bark or wood chips with aged manure or compost and work into soil before planting. Plants will respond by putting roots deep into the soil that stays cool and moist all summer.

4. Water Wisely. Grass benefits most from sprinklers. Trees, shrubs, garden flowers, and ground covers are watered mostefficiently with low-volume drip, spray, or bubbler systems. Remember to regularly check your watering system and adjust forseasonal changes. Less frequent, deeper watering promotes root growth and drought tolerance.

5. Group similar plants together in their preferred site conditions. Divide your garden into low, medium and highwater zones. A medium water zone may include a shady north exposure that takes less water to stay moist. Sloping southernexposures are best planted to tolerate low water conditions caused by rapid run-off, sun, and wind.

6. Mulch planting beds. Mulch covers and cools soils, reduces weed growth, and slows erosion. Mulches include shred-ded bark, wood shavings, crushed nut shells, and rock or gravel. Avoid using plastic in planting areas.

7. Maintain your garden. Weeding, efficient watering, and pest control will keep your plants healthy and conserve water.Fertilizers promote growth but increase water consumption. Apply the minimum amount of fertilizer needed.
