Geranium pratense Plenum Album

The perennial Geranium pratense Plenum Album should be planted in spring or autumn. This variety, like all other perennial geraniums, is undemanding in terms of location and soil quality. It can be placed in any fertile soil that is not waterlogged, preferably moist and richer than the typical species that prefers dry soil. It tolerates limestone. Geranium Pratense thrives in the sun, which promotes flowering, or in partial shade.

To plant your young plant,  prepare the soil to a depth of 20 cubic cm, crumbling the soil well.  Add a fertiliser to the base of the hole such as bonemeal.  Position your plant, removed from its pot, by covering the top of the root ball with 3 cm (1in) of soil. Fill in the hole and water generously to eliminate any air pockets. In dry weather, it will be necessary to water regularly for a few weeks to help the plant to establish.  However, water sparingly in winter. Apply liquid fertilizer twice a month. From July to September, remove faded flowers and leaves to encourage new growth. If the foliage has not been affected by cold weather, trim the large clumps every spring to keep them compact and promote new vegetation. You can also trim after flowering and water well to encourage the plant to produce a neat clump. Divide the geranium regularly.
