Plant Nanny Stakes. Water less often, while you recycle your plastic bottles! Just insert a terra cotta stake near the plant's center, fill a bottle with water, attach the bottle to the adapter and set it in the stake. It's easy to see when more water is needed. Ideal for houseplants and container gardens. Great when on vacation. Sturdy enough for 2-liter bottles.This includes 4 stakes per set.(5 ½" h).
Make a self-watering planter: Cut bottom off empty plastic bottle. Poke a hole in the bottle cap using wooden skewer. Fill with water, making sure you get a slow drip of water through the hole with skewer in it. Put in your flower or vegetable planter, making sure skewer is in the dirt to hold the bottle. Great for hanging planters to keep them watered! Refill with rain water or hose as needed.
