Keep a potato around until some eyes start growing on it. Slice a piece of the potato off where the eye is, and put it in a cup with water covering the potato, but not the eye. Soon, you'll have a potato plant sprouting up and you can plant it in the garden, or just watch it grow in the cup (no potatoes will grow in the cup, but the plant will grow and look good.)
Epson Salt & Lawn Care. For every 100 square feet of lawn, the Dirty Doctor recommends applying half a pound of Epsom salts over the lawn using the spreader. Alternately, combine 1 ounce of Epsom salts with a gallon of water, blend thoroughly, and use a mister to treat the lawn with the mixture. Awesome natural fertilizer!
