Also remember to add quite a bit of Epsom Salt to all your soil. This is NOT a sodium, but a magnesium supplement. This is only one of the elements that has been used and not replaced in our soil. All plants seem to love it, and my DH, a nurseryman, bought it in 50 pound bags to use on everything on the place. He brought it home and used it on all our plants, and the lemon tree out back loves it. Makes the skin thinner, fruit larger, juice sweeter. DH would take handfuls of it and hurl it around to make it look like a brief snowfall. Then water it in.
