3. For larger jars, drill holes into a length of 2-1/4-inch-diameter PVC pipe at 4-inch intervals. Before planting, insert the pipe in the jar's center, down through the soil to the bottom pocket. This allows water to seep down, soaking lower plants. Finish with several plants at the top, spacing them tightly for a full, flowing look. Water well.
4. Keep moist. Container gardens dry out quickly, so water often, with plant food added. Moist soil and vitamins will keep your garden thriving. No extra maintenance is required except an occasional manicure. Pinch off dead leaves and overripe fruit to keep plants fresh-looking. Rotate the jar one-quarter turn every few days (try a plant caddy) to give plants and berries enough sunlight.
