Nectar of the gods, this big hairy weed makes the best plant food for your veggies. Super cold-hardy, grows anywhere, dainty little blue, pink, or cream bell flowers - but the leaves are the real draw, as any keen gardener knows. Add them to compost heaps; shred for a green mulch; and make comfrey tea : it smells terrible, but to a plant it's a protein power shake.
DESCRIPTION: Vigorous perennial with large soft leaves and tiny pink, blue or cream tubular flowers in spring-summer. Long grown for its herbal and medicinal applications. PLANTING: Sow seeds in Autumn-Winter outside in cold climates; or in frost-free regions place seed in a bag of compost in the fridge for 4-6 weeks. Plant out at 20C. Keep moist until seedlings emerge. USE IN: Green mulch, compost heaps, comfrey tea. CARE: Prepare soil prior to planting with well composted manure, mulch plants to retain moisture in the soil. Water regularly. Harvest leaves from the second year on as the flowers start to emerge; wear gloves as the leaves can irritate sensitive skin. half fill a bucket or water butt with leaves, weigh down with a brick, add water to cover. Put a lid on and leave for 3-6 weeks. Dilute at least half-and-half, up to 90:10 before use. Makes a good feed ad as a foliar spray can combat powdery mildew in roses.
