An acidic soil or growing medium is another reason for dryness Ubdustrial. Liming the soil is one way to raise the Ph but I prefer freshly ground rock, preferably glacial gravel eg. granite and gneiss. The finely ground rock dust helps retain moisture and also provides minerals to the plants, which in turn pass them on to the consumer. I recommend the books: The Secrets of the Soil, Bread From Stones and Remineralize the Earth.

Acid rains have leached many essential minerals and rare earths from our soils and the best way for us to replenish these in our gardens (or containers) is by grinding them from rock ourselves rather than waiting for the next ice age.

Put some golf ball sized rounded stones in a metal can and place them in a campfire or wood stove until they get cherry red. Quench them in a bucket of water to help them fracture. Then smash them with a large hammer. You'd be amazed how easily they can be pulverized into a fine powder. Obviously, great caution must be exercised throughout this procedure like wearing safety glasses, gloves and using common sense. Never put flat rocks or shale into a fire. These contain moisture and the rocks will pop. Glacial gravel is mostly "parent rock", rocks from which all other rocks were formed. Parent rock like granite contains minerals in a homogeneous mix.

An easier way to remineralize your soil would be if you could get some of the slurry from settling ponds at your local quarry or from stone cutters i.e. tombstone companies, counter-top manufacturers. I like doing it myself because I can pick and choose the prettiest smooth stones.

The best soil I have ever experienced growing produce with is 1 part soil, 1 part yard waste compost and 1 part rock dust. I call it the Trinity Blend. A lighter mix is recommended for container gardening and should have at least 1 part peat moss (or shredded cardboard, newspaper, etc.)

FWIW - In my travels I saw a company that specializes in worm poop. I think it was in Guelph and it might be worth looking into. Worm poop is nature's best fertilizer and we can gauge the health and fertility of our garden soil by the quantity and quality of the worms therein.
