Where to plant and grow
Any good rich soil is suitable. Plant the perennials in the autumn or spring, choosing a sunny position where the plants can climb over a trellis, wall or other support. These plants need a lot of water in the growing season and they should be fed during the summer with liquid manure or a balanced 2 fertilizer. In the autumn cut down the stems and top-dress with manure in the spring. The perennial species are propagated by seeds or by division of the roots in the spring.
