Tis time to put the Gardens to bed for the winter. Now is the time to get the soil test kits and make the necessary adjustments to your soil for next years growing season.
Some leaves, a little lime, some fertilizer (either natural or commercial) and micro elements is what is normally needed to be tilled under now for a bountiful crop next year.
I usually till a little Epsom Salts under for the required Magnesium some plants need.
