Environment Canada has issued several heat warnings for parts of Vancouver Island and inland sections of coastal B.C. We get the latest from CBC's science and climate specialist Darius Mahdavi, and Dr. David McVea, public health physician with the B.C. Centre for Disease Control, and discuss how residents can prepare for the hot weather. And then, our gardening columnist Brian Minter is back to answer your questions and share his advice for caring for your garden as the weather gets warmer.
