Clear grass around shrubs?
This may sound like a very basic question, but you have to learn somewhere. It seems like I've read it is advisable to clear grass away from the base of shrubs, small trees etc.
Despite having good mulch around some crepe myrtles, boxwoods and a couple of little trees, the bermuda was getting pretty thick. I've cleared about a foot around these, a feel it has greatly helped with deep watering.
Anything else I should know about this practice? Any need to do it around more mature trees?
How often should I water in this extreme heat? More than 1 deep watering a week?
