Rain Gauges

Rain gauges are useful tools for weather watching, and they can contribute to healthier plants, too. Irrigating the garden is only necessary when rainfall isn't adequate. So it's always a good idea to keep track of how much rain your landscape is getting.

Keep in mind that the water needs of plants can vary, depending on the season and the landscape. But many plants need at least some water every week during the warm months.

For an accurate measurement, place your rain gauge somewhere in the landscape away from trees, the house, and irrigation systems. Be sure to empty the rain gauge after it rains so that you can get an accurate reading each time. For the high-tech gardener, get an automatic rain gauge that registers inside and empties itself.
