The best time to plant herbs into your garden is on a cloudy day. But if you absolutely have to put them in on a sunny day, you can create shade for the plants. One easy way to do this is to stick a cedar shake/shingle in the ground on the south side of the plant. Tilt the shingle slightly to cast the most shade on your plant. Press it in firmly so it doesn’t fall over. You can get a bundle of cedar shingles at a building supply store. The shingles are smoother and thinner than the shakes. Both are of various widths. The wider ones can be split into more narrow ones. At the very least you will amuse your friends and neighbors with your ‘shingle garden’.
