Pruning Hydrangeas

Pruning hydrangeas after they have finished flowering is crucial for maintaining their health and encouraging abundant blooms in the following season. The best time to prune hydrangeas is in autumn or early winter, after the flowers have faded. This timing allows the plant to focus on root and stem development during the dormant period.

When pruning, it’s important not to cut back any stems that did not flower in the current year. These non-flowering stems are the ones that will produce blooms in the upcoming season. By preserving them, you ensure that your hydrangeas will have a robust and vibrant display of flowers next year.

Begin by removing any dead, diseased, or damaged growth. Dead stems can be identified by their brittle texture and lack of green tissue inside. Diseased stems might show signs of discoloration, spots, or unusual growth patterns, while damaged stems could be broken or split.

Additionally, thinning out some of the older, thicker stems at the base can improve air circulation and light penetration, promoting healthier growth. By following these pruning guidelines, you will help your hydrangeas thrive and continue to be a stunning feature in your garden.

Pruning Salvias

Pruning salvias is essential for maintaining their health, encouraging prolific blooming, and keeping the plants looking tidy. The best time to prune salvias depends on the variety, but generally, there are two main pruning periods: after the first flush of flowers in mid-summer and again in late autumn or early winter.

Late Autumn or early winter pruning

In late autumn or early winter, after the salvia has finished blooming for the year, a substantial pruning is necessary.

Cut back the entire plant to about 1/3 of its original height. This hard pruning removes any dead or diseased stems and helps to shape the plant for the coming year. It also prevents the plant from becoming too woody and encourages fresh, vigorous growth in the spring.

For perennial salvias, avoid cutting back into the old, woody growth too aggressively, as this can damage the plant.
