Indoor Cultivation

While all Geraniums can be grown as indoor pot plants, they are ideally suited for summer bedding, hanging baskets or outdoor containers. When grown indoors they need to be shaded from the hottest sun as this will help to prevent the flowers and foliage from fading. A free draining compost is ideal. Water freely in summer and sparingly in winter. Feed every two weeks in the summer with any good fertilizer.

Outdoor Cultivation

If growing outside, choose a sunny frost-free site with well drained fertile soil. You will reap the benefits from adding a fish, blood and bone fertilizer to the soil as you plant, but take care that this is well worked into the soil and does not come into direct contact with the roots. During the flowering season, regular deadheading will ensure a long flowering season and although not essential, a high potash feed mid-season will pay dividends.

Geraniums grown outdoors need to be lifted before the first of the sharp frosts, and they can then be trimmed down by at least one third, potted up and kept in a frost-free situation.
