"Stress-free watering"
I started with a couple of these and was so impressed I have enough to go in all my summer hanging baskets. Once the foliage has grown up you can't see the ball. I also have them in plants in the conservatory and they work extremely well. I recently lent 6 to a friend who was going on holiday and all her plants survived 6 weeks while she was away. Can you sell them all year please?
