Made from durable, weather-resistant polypropylene, the set includes 30 connector pieces that combine to form rings from about 20 cm (7.87\") up to 150 cm (59\") across — a flexible solution for yards, vegetable patches, container gardens and landscaping projects.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these rings help my plants stay hydrated?\u003c\/h3\u003e\n\u003cp\u003eThe rings form a shallow basin that holds irrigation and rainfall at the root zone rather than letting it flow away.
