Your guide to Flowering Pelargoniums

A few simple practices will encourage plants to remain healthy, vigorous and full of flowers.

Sunlight: The Key to Abundant Flowering ☀️

Pelargoniums thrive in warmth and sunshine. A bright position, ideally with several hours of direct sun each day, will encourage steady growth and abundant buds. Patios, terraces and south or west-facing windowsills are particularly well suited to them.

Plants grown in good light tend to remain compact and floriferous, producing far more blooms than those grown in shade.

Feeding for Continuous Blooms 🍴

During the growing season pelargoniums benefit from regular feeding. A liquid fertiliser high in potash, applied every week or ten days, will support both healthy foliage and the steady production of flowers.

This small amount of attention makes a remarkable difference to how freely the plants flower through the summer months.

Deadheading: A Simple but Important Habit 🪴

Removing faded flower heads encourages the plant to produce fresh buds rather than diverting its energy into seed production. Regular deadheading also keeps the plants looking neat and encourages a steady succession of blooms.

A few seconds spent removing old flowers when watering is often all that is required.

Watering with Care 💦

Although pelargoniums appreciate regular watering during warm weather, they prefer compost that drains freely. Allowing the surface of the compost to dry slightly between waterings helps maintain strong roots and healthy growth.

Overly wet compost, particularly in cooler conditions, can slow flowering and weaken the plant.

Planting Early for a Longer Season 🕰️

One of the simplest ways to enjoy a longer display of flowers is to start your plants early in the season. Pelargoniums grow steadily when given warmth and good light, so planting them early in spring allows them time to establish and develop strong growth before the main flowering period begins.

Many gardeners grow their plants in a greenhouse, conservatory or bright windowsill early in the year before moving them outdoors once the weather becomes reliably warm. By the time summer arrives, the plants are already well developed and ready to flower freely.

Starting early often means plants will come into bloom sooner and continue producing flowers for much longer.

With good light, regular feeding and a little care, pelargoniums will reward you with a succession of flowers for many months..
