Perennial upright geraniums (which are correctly called pelargoniums) are easy to grow and offer bright, colourful blooms over a long period.

How
Look out for the Selecta range of zonal geraniums: we love ‘Emotion’ for its rich cerise colour and large flower heads. Geraniums love the sun, and are
best grown in pots to ensure they good drainage they require. As they grow, tip prune regularly to keep the plants bushy, and water in dry times. Regular
feeding with a fertiliser high in potassium, such as Phostrogen, will ensure great flowers. Zonal geraniums are easily grown from cuttings, using a
hormone gel or powder. Autumn is the best time for cuttings, but they will strike all year.
Pests
Caterpillars that eat holes in leaves and flower buds, and fungal diseases causing spotty leaves, can affect your geraniums, especially in humid coastal
areas. A spray such as Yates Rose Gun will treat both problems.
