Hot & Dry
from Focus on Flowers Hosted by Indiana Public Media
I don’t have a watering system, so I get tired of watering when there are long periods of hot, dry summer weather. Here in the Midwest when it is over 90F, potted plants need watering twice a day and beds on slopes do too. It is a chore that makes me wish I had more drought tolerant plantings. A drought tolerant landscape does not mean zero watering, but it requires plants that can tolerate low amounts of water, even in extreme heat. Xeriscape plantings (“Xero” is the Greek root meaning dry) still need some watering during extended dry periods, but less than other plantings. While plants are getting established, they need deep watering to ensure good root growth. This is essential if you have sloping beds, as I do, and hillside plantings where water runs off. Sedums, lavenders, euphorbias, yuccas, yarrows, alliums, lilyturfs, salvias, oenotheras, santolinas, lobelias, gauras, coneflowers, and coreopsis are not big drinkers. Remember, too, that small plants need less water than tall plants, so grow lower varieties or keep plants pruned back when it is hot. Afternoon shade is also helpful.
