Rinse small plants at the kitchen sink in a spray of tepid water. Cover the soil with foil or plastic film to keep it from washing out of the pot.

Ask for "Judy's Wild Oats" at Flowers & Plants Etc., 1378 Chain Bridge Rd., McLean, or at your garden center.

Start an avocado tree. Wash the seed and remove the papery brown cover. With pointed end up, insert three toothpicks in the seed so that it will rest on the rim of a glass or jar.Suspend the seed, broad end down, in the jar of water with the bottom sitting in about 1/2 inch of water. Set the jar in a warm place out of direct sunlight. Remember to replenish water lost through evaporation. In a few weeks, roots will appear at the bottom and a leaf sprout at the top.
