I just ordered something that may just prove its worth several times over. I ordered a Sunlight Calculator. It's been advertised in many places, but I ordered it through the Garden Gate magazine's store online.
Garden Gate has been my favorite magazine for years! There are no distracting advertisements or ads unrelated to gardening. Each issue is devoted to a couple of different subjects (just look it up!) with many tips and hints by the editors as well as fellow gardeners.
The sun calculator is used to determine, exactly, the amount of light portions of your garden get. After placing the calculator in the bed, it measures the amount of light over a 12-hour period. The intention is that it will help me choose plants that will best thrive in particular locations.
I'm excited to use this tool. While I won't get the right indication of light in my gardens until the trees are fully leafed, I'll be able to experiment until I need to use it. ;-)
I already anticipate the need to move a few plants... hopefully this will help me determine "where."
This IS a shady subject! ;-) And I just thought you'd like to know about it.
