When temperatures reach the levels we’re going to and have had over the last week or so most watering schedules are not sufficient. Please check your plants daily for sufficient moisture. It will be normal for plants to wilt in the middle of the day, so we’d suggest checking in the early morning hours. If the plants are already in wilt they will be in big trouble by the middle of the day. Concentrate on watering deeply, hours not minutes, when it comes to drip systems and don’t be afraid to override your schedule for a few days and turn the timer on manually if need be. A hint is to have an “indicator” plant in your landscape. What we mean by that is a plant that might show signs of needing water first. In the case of the nursery, we look at the cape honeysuckle and or duranta. They will tend to show a slight wilt when they need watering before any of the other plants do. A little wilt will not damage your plants if you water sufficiently and in a timely manner after it shows up. If your indicator plants show a little wilt you know the rest of the landscape probably will need watering soon anyway! So get out while it is cool and check your plants even though you have an “automatic” timer on your system. Your timer can’t see or sense the change in the weather, unless you have one of the new “smart” timers. Gardening is a touch and feel thing and without the gardener there is no garden, your timer doesn’t care!
