The earth just yields beauties. We planted the cabbage in a row and the watermelons grew all over this summer. In this plot, we water pretty seldom, just let it grow and see what happens. Not bad for low maintenance!
These actually seem to work pretty well. We bought some for a very large fern that we bring in during the winter months. We are going to be on vacation for over a week and wanted to make sure the fern got watered, without the need to have someone come into the house and water it.
We tested it before we left. We bought a 3 pack and put them in 3 different containers around the fern. We found that they were about the same as watering our plant 1/2 of the water it needed. We then bought another 3 pack. Perfect amount of water!
Our fern is HUGE though and really takes a ton of water. It is about 3 1/2 feet tall and about 4 feet wide. Without the spikes, we had to water it every other day and about 32 ounces of water each time. These spikes really do the job!
