Geranium White

Geranium macrorrhizum 'White Ness' a variety of Cranesbill Geranium, is a hardy perennial plant with lovely white flowers.

To ensure the health and beauty of this plant throughout the year, it's important to provide seasonal care tailored to its specific needs. This guide explains how to care for Geranium macrorrhizum 'White Ness' throughout the seasons.

Spring

Pruning and Maintenance

In early spring, inspect your Geranium for any dead or damaged foliage from the previous year and gently prune this away using clean, sharp secateurs to promote new growth.

Feed

Encourage new growth by applying a balanced, slow-release fertilizer. Follow the manufacturer's instructions for the correct dosage.

Dividing (if necessary)

Spring is an appropriate time for division if the plant has become overcrowded or the centre has died out. Lift the plant, divide the root clumps, and replant them in well-prepared soil.

Watering

Gradually increase watering as the weather warms up. Geranium prefers consistently moist soil but not waterlogged.

Summer

Pruning and Maintenance (if needed)

Remove spent flower heads to encourage continuous blooming and maintain a tidy appearance.

Mulching

Apply a 2 to 3-inch layer of organic mulch around the base of the plant to retain soil moisture, regulate temperature and suppress weeds. This is especially important in hot and dry summer conditions.

Watering

In the warmer months, Geranium benefits from regular watering. Keep the soil consistently moist, but be cautious not to overwater, as it prefers well-draining conditions. Deep, infrequent watering is preferable to frequent shallow watering.

Autumn

Pruning and Maintenance

As the growing season comes to an end, trim away any remaining spent flower heads and dead foliage to tidy up the plant. This helps prepare the plant for winter.

Protection from frost

While Geranium is frost-hardy, providing some protection, such as mulch, can help during severe frosts, especially for potted plants or those in exposed locations.

Winter

Pest and disease prevention

Pests and diseases are less active in winter, but it's essential to monitor your Geranium for any signs of issues and address them promptly
