5 Water conserving Tips for Summer Gardening

12/14/2018 (Permalink)

To keep your grass or your garden alive during the summer heat wave without driving your water bill to new heights, follow these tips.

1. A standard garden hose and nozzle is the least efficient means of applying water to plants because so much water is lost as mist, runoff and evaporation. Use a soaker hose or a sprinkler wand.

2. For most Americans, a good rule of thumb is that a lawn needs 1 inch of water a week and perennial plants and shrubs will need from 1 inch to 2 inches a week. There's no neat rule for watering annuals, so your best guide is always the plant tag (the small spear-shaped plastic tag that came with the plant when you bought it). It will tell you the sun, soil, pH and water requirements.

3. When in doubt, keep the plant's soil lightly moist and see how it responds. If conditions are especially hot and windy where you are, keep a careful eye out for wilting. If you see the signs, add water to the soil, but don't overcompensate by drowning the plant. Over-watering is just as bad as under-watering; it leads to root rot and soil compaction that robs the roots of air.

4. Don't soak the plant's foliage; it does little good. And don't apply water outside a shrub's or a perennial's root zone. A shrub's root zone is roughly 1 to 3 times the diameter of its canopy, and keeping the water inside this radius will allow it to soak down to where the plant's roots can reach it. If you see water puddling or running off, stop; let the water soak in before resuming. Likewise, water that runs off your lawn or off the top of a flower bed onto paved surfaces does no good. The same applies to running lawn sprinklers: Water your lawn, not the side of your house or the driveway.

5. Mulch is great for holding in moisture and keeping the base of plants cool. However, a thick layer of mulch can also form a crust that prevents water from soaking in. Break up crusted mulch with a rake to allow water in.

You can buy a tool to gauge your soil's moisture level at a nursery or through a horticultural supply catalog. But if you don't have one, a large straight blade screwdriver is a good standby. Poke it into the soil; the drier the soil, the more resistance you'll meet.
