Make a shade map of your garden
Handy Hint....A shade map is one of the most useful things you can do in your garden. Most of us don't really know when any particular spot is sunny or shady. This is what you do. Make an outline sketch of areas of your garden. You'll need copies for all 4 seasons. Go out into your garden at 9 am., noon time and 3 PM. I like using colored pencils but different pencil shadings can do the same thing. At 9 a.m. shade in the areas that have full shade or full sun....or anything in between. Do the same thing at noon and at 3 p.m. Using different colored pencils makes it easy. You will then have an accurate idea of which areas are full sun or just partial. Do the same thing in each of the four seasons and keep those records where you can find them.
