It's May in South Central Texas. The weather is gorgeous and we're looking forward to poolside days and cool lemonade. While things are warming up, we may still see enough cool days (especially in the mornings) to enjoy the yard.
As temperatures rise, you'll be concerned with watering. Water so that you apply an inch of water each time you water and then don't water again for a week. If it rains, don't water unless it was one of those whimpy rains that did nothing but wet the top of the soil. The soil should be moist and cool an inch down. Remember to observe watering restrictions.

We see some warm days in May, and just a little rain. And, as you may know, in San Antonio, we can't count on consistency in our weather patterns! Even in a dry year, we'll still get a little rain. The average home uses more than 50% of its water on landscaping! Investing in a rain barrel will help your plants, and save money!
Watering is the single most important activity in the garden this month! Water established plants deeper and less often. Newly seeded areas may need daily attention. Water as needed and turn off your automatic sprinkler system if we've seen some good rainfall. The best time to water is in the morning: daytime watering wastes too much precious water to evaporation.
