For sweet peas, peas, beans, leeks and tap rotted plants. These bottomless tubes encourage strong root growth and the whole tube is planted out. Grow Pots - Made from paper and textile fibres, these pots are planted directly into the soil and biodegrade as plants grow. Grow Pots keep roots warm and moist for vigorous growth. They also protect roots from transplant damage as you plant the complete pot. Once old enough, the roots will break through the pots and continue to grow as normal, whilst the pot slowly biodegrades. Pack of 16. Grow Tubes - Made from natural, biodegradable materials, Grow Tubes will protect the roots of cuttings and seedlings that require planting out. Great for sweet peas, peas, beans, leeks and tap rotted plants. Sow one seed per tube. Keep tubes upright by tying with string. Plants are ready for planting out when roots begin to grow through the sides - simply transfer straight into the ground and water thoroughly. The rim of the tube will also act as a deterrent for pests. Made from paper and textile fibres, these pots are planted directly into the soil and biodegrade as plants grow. Pack of 20. 6cm.
