Biennials live for 2 years, whereas perennials live for longer. As a general rule, biennial and perennial seeds should be sown in spring, but some can be sown in autumn as well. Many varieties will self-seed after flowering, giving you even more plants!

"Rootgrow can be used with all seeds, bulbs and shrubs & roses - with the exception of Brassicas (cabbage, sprouts, cauliflower, broccoli), Rhododendron, Azalea, heather, cranberries and blueberries. It is easy to use, just sprinkle the required amount in the planting hole to help your plants establish an improved natural vigour, a stronger root system and better drought tolerance." Add rootgrow™ to your order.
