It usually is best to allow the soil in your garden to partially dry out between watering your plants. If you can see your footprints in your lawn or if it lacks overall shine then it's time to water your lawn. Annuals and vegetables should be watered at the first sign of droop. Tougher plants that live several years only need watering when you see they stay droopy after it cools off in the evening.
It is important to reach down to the roots when you water, so water long enough and deeply to help moisten the whole root zone. When plants are watered deeply they build healthier, stronger root systems. To determine if you are watering deep enough to moisten the whole root zone, just dig in with a trowel after watering to check the depth of the moisture.
Of course, sometimes this can be costly or there may be drought condition. There are ways to lower water bills and maintain more moisture to your plants which include the following. Build your soil with mulch and/or compost, to hold water and prevent evaporation. Choose low water use plants which, once established, can often thrive just on rainfall. Using soaker hoses or drip irrigation on beds can save 50% or more of water usage compared to sprinklers. To water just the right amount use a timer that screws right onto the hose end. Water your lawn separately from other plantings or your vegetable garden. They each absorb water at different rates. Ever found out you are watering the pavement instead of the lawn? Make sure sprinklers are set up efficiently. When soil is dry or compacted it won't absorb water quickly. If water puddles, stop watering for a while and then restart, so the water has time to soak into the ground. Water in the early morning or evening. If you water during mid-day half the water evaporates quickly with the heat of the sun. Practicing these simple, easy steps can make every drop count.
A way of making watering easier is to get a garden hose reel. Hoses, especially the longer ones, tend to get tangled or even knotted. This is frustrating and time is wasted trying to get the kinks out in order for the water to flow through the hose. A watering reel eliminates these problems and stores the hose in a compact area ready to use whenever you need it.
There are pros and cons to automatic watering systems. They can either waste lots of water or be a fairly efficient way of watering. It is recommended that every year you should have a professional test, repair and adjust your system. And you should inspect the system while operating it once a month. Look for any leaks, or heads that are plugged or misdirected. This maintenance is important for the system to run efficiently. Install a rain shutoff device. No sense in watering when it is raining. Also, adjusting the watering schedule according to the season helps. In July and August your garden and lawn need much more water than they do in May or September.
