Where to plant pelargoniums
Pelargoniums can be grown in garden soil of any types but will benefit from a neutral or alkaline soil. Grow in a position of full sun in containers, hanging baskets or flower beds.
If growing under glass, protect them from direct sunlight in high summer.

How to plant pelargoniums
When growing in containers choose a multi-purpose compost with added slow-release fertiliser. Pelargoniums look spectacular when planted with other summer bedding plants. If planted in a good compost and kept well-watered they’ll withstand being planted tightly with other tender plants.

How to propagate pelargoniums
Take pelargonium cuttings from the new growth of overwintered plants in spring. Cuttings can be taken in late summer if preferred.
To remove cutting material, cut above the third joint below the growing tip. Pinch out any flowering buds that are forming. With a clean knife remove all but the top two leaves. Recut the base of the cutting just below lowest joint.
Fill a plastic garden pot with cutting compost and firm the compost down. Water and insert the cuttings into the compost by about 1cm. Position pots in a warm but not hot place that is light. Don’t forget to label the pot if you’ve taken cuttings from lots of different varieties.

Pelargoniums: problem solving
Zonal pelargoniums only are susceptible to pelargonium rust. This is a fungal disease that is often worse in wet summers or when plants have been grown in a poorly ventilated space. Rust is easily spotted as the underside of leaves displays brown spots.
Destroy plants that are covered in the brown spots or head to the garden centre to by a suitable fungicide.

Looking after pelargoniums
Water plants well in summer and deadhead to encourage a second flush of flowers.
Pelargoniums are often grown as annuals and are composted at the end of summer. If you have room in a frost-free place, then it’s worth trying to keep them overwinter.
To overwinter, lift plants that are in garden soil or large pots and pot them into a smaller pot. This should be done before the first frost. Removed any damaged leaves and faded flowers. Cut plants back by about a third and position in a frost-free but bright place. The plants don’t go into complete dormancy so water lightly through the winter. In spring feed and step up the watering. Plant out only once the danger of frost has passed.
If growing pelargoniums as houseplants, you can let the plant carry on flowering, which they may do all year round. Keep indoor pelargoniums away from radiators or open fires.
Pelargoniums for scent
For scent grow the scented-leaved pelargoniums. Choose from apple, orange, lemon, spice or lavender. They’re often sold as herbs as the leaves are edible.

Should I water overwintering pelargoniums?
Transcript
Yes, you should water pelargoniums over winter, but sparingly. It’s easy to get these plants through the winter as long as they’re kept frost-free, well-ventilated and not quite touching each other. They have succulent stems and only need watering when they show visible signs of wilting. Do so in the morning on a mild day and make sure the water is able to drain freely from the pot.
