Garter snakes- a gardener's best friend

Garter snakes are only mildly venomous, and even if they bite you they don't produce enough to harm a human. But they are very effective predators, eating slugs, insects, worms, frogs, minnows, and even rodents if the snake is large enough, all of which (except the worms, minnows and frogs) are generally bad for your garden. They have very distinctive markings- three yellow stripes run their length on a dark or black background. Garter snakes give birth to live young, unlike most reptiles. Adults can range in size from 45cm (18") to over a meter (over 45") at the very top end (but that would be a rare one, and probably wouldn't find enough food to stay in your back garden).

Starting a new garden bed

A garden is nothing without a good foundation, and that foundation is the soil. Soil has its own complicated ecosystem from worms and beetles on down to tiny, nearly-microscopic filaments of fungi and bacteria. As with anywhere on earth, a healthy ecosystem is essential for optimal growth and health.

In my backyard the soil is a heavy clay over a base of sand. It barely grows grass in some places. But, if you build it they will come... The raised bed that I put in last summer is nearly overflowing with worms, and centipedes are fairly common, too, much to my husband's chagrin. It started off life as a lasagna garden, with a base layer of cardboard boxes recycled after the move, a couple bags of dirt from the grocery store garden center, and some trench-compost piles. Now there's enough good dirt to grow short-ish carrots, and my herbs are taking off. The bed isn't very large because it takes a fair input of cash to start that way, with the boards and hardware to attach the corners. I used two un-treated cedar deck planks and cut them down to a rectangle.
