Containers can come from anywhere, not just your local garden center. Head out and get inspired with the selections in your local thrift stores and garage sales, and use your extra cash for more plants instead.
I love thrift stores for containers.. You can usually purchase the for a few dollars, but are also unique. Baskets and trays are great. I also like upside down light fixtures, but so far have kept my attempts to ones with holes. Any ideas to keep roots dry?
