These thrive most in a peat or bog soil, but where this cannot be obtained a good fertile loam, with a dressing of fresh cow manure once in two years, may be used; or leaf-mould and soil from the surface of pasture land, in the proportions of three parts of the former to one of the latter. The soil should be chopped up and used in a rough condition. Sickly plants with yellowish foliage may be restored by applying liquid manure once a week during the month of July. A light top-dressing of cow manure applied annually, and keeping the roots free from stagnant water, will preserve the plants in good health.
