- Geraniums love sunlight, so find a spot that gets 5–6 hours of direct sun a day, preferably sheltered from afternoon sun.
- Their soil needs to be well drained. Clay soils are okay, but dig in plenty of compost, and mound the soil before planting to improve drainage. Geraniums also grow well in pots filled with premium potting mix.
- They like to be watered regularly, but let the soil dry out between drinks. Too much water can cause their roots to rot.
- Feed them with a flower and fruit fertiliser every two months or so when they are in active growth. Slow-release forms are best for plants in containers. Liquid fertilisers are also effective, but need to be applied every fortnight or so.
- Remove spent flowers and old leaves regularly to keep plants looking healthy and tidy. Cut them back by about a half in March or April to keep plants compact and encourage lots of fresh new growth.
Have you discovered scented geraniums? These are a special group with an array of fragrances that mimic the perfume of other plants. Crush their leaves and you’ll release a scent of rose, lemon, cinnamon or peppermint. We profile scented geraniums in the January issue, and show you how to use them to perfume everything from chocolate cake to car interiors.
