Plants and High temperatures
Well as everyone knows there has been a huge HEAT WAVE. Here in southeast PA we had rain on June 28th so drought is not the problem...it is the 100 degree temp. Leaves are starting to curl up & turn brown & wilt.
Does this mean the plant is just going 'dormant', adapting to the heat, hunkering down... or is the plant going to die? How do I tell the difference? (I know when a plant is completely dead of course.) I have perennials and shrubs. If the tops curl up & turn brown, will the roots survive and will they come back next year? I only started gardening in april of 2011. There is a lot I don't know yet. If I see the plant starting to fade, should I give up & save the water for a plant that has a chance?
