Containers are the most versatile way to show your gardening creativity. Containers can be those classic terracotta urns, but they can also be ‘found objects’ from your home. Betty Sanders will do more than just talk about container gardening at the next Wednesday Night at Elm Bank lecture on Wednesday, May 25 beginning at 7 pm: she’ll put together five distinctive container gardens, explaining both the basics and the tricks experts use. You’ll leave both with a lot of new knowledge and with the confidence to try it on your own.
