Spring is the ideal time to prune hydrangeas. Kate Bradbury explains how to make the right cuts, and which feeds to use after you’ve pruned.
Remove the dead flowerheads of hydrangeas in March, cutting above a pair of fat buds on the stem. Spring is also a good time to thin out tall, bushy plants, by taking out a third of the older stems, close to the base. Apply a slow-release fertiliser after pruning, then mulch with organic matter, such as well-rotted manure or garden compost.
