Question: We have frequent water curtailments in the summer. Which grasses are most tolerant of drought?

Answer: Buffalograss and bermudagrass. Fact is, both will survive almost any summer drought, although both will go brown and dormant during the dry period. Of the two, bermuda is the more aggressive. If you intend to water at all during the summer to keep your lawn at least modestly green, and if there is bermudagrass in your area, it is likely to take over buffalograss in spite of any and all efforts you might make to keep it out.. Given even that minimal level of care, bermuda will invade the buffalograss and take over the area within just a year or two. To avoid disappointment and frustration, bermudagrass is always the safe option.
