Your wife might have always been jealous of Aunt Mable’s petunias, but with the EasyBloom plant sensor [$39.95], green thumbs are no longer a requirement for good gardening. It differs from other in-ground sensors in that it interfaces with an Internet database. Simply plug it into your computer to sync it, stick in the ground, and wait 24 hours. Depending on what you choose, the EasyBloom will either tell you why a plant is doing poorly or suggest plants that will grow well in your environment. If you’ve recently moved to a new area or are just getting started in gardening, the Easy Bloom is essential to have around.
