This durable, portable, once piece cloche creates a mini greenhouse that helps warm the soil and protect plants. It can extend the growing season by weeks. Adjustable vents at each end help prevent overheating. Lift the cloche using the attached handle on the top for easy access to plants. It's particularly useful for early transplants of tomatoes, peppers, melons, and other heat loving plants that may struggle against cool weather in spring. Try using the Row Garden Cloche to keep frost off winter harvest herbs like parsley and chives or salad greens like mustard and lettuce. The unit ships flat, but once assembled measures 100cm (39¼") long, 44.5cm (17½") wide, and 35.5cm (14") tall.
