Clever Gardening Technique

Mini Greenhouse
Get seedlings off to a good start by protecting them with a mini greenhouse made from recycled soda bottles. Use a knife or scissors to cut the bottom off of a clear plastic soda or water bottle. Remove the cap to allow for ventilation. At planting time, cover seedlings with the prepared bottles by pushing the cut end into the soil at least one inch. The bottle will collect heat, preserve moisture, and prevent insect pests and birds from eating your seedlings until they become established. Once the plant is growing well, remove the bottle.
