All plants are susceptible to withering and damage during a heat wave. New plants, however, are more likely to suffer irreparable damage because they are not established in the garden yet. They have not developed much-needed deep taproots, which stay moist longer than shallower roots and help search for water when water is scarce.
Well, here we are again. Smack dab in the midst of the “dog days of summer”. And Lord have mercy, heat indexes in the hundreds of the weekend. GEEZ!!!! Yes, those sweltering, hot, humid conditions are back. You know the “dog daze of summer” officially started on July 3rd and run until the 11th of August.
