Late Winter Pruning Technique

When pruning in late winter, bear in mind to cut in a slant, directing towards the cluster's exterior. This helps with proper water drainage. The annual pruning to boost flowering involves cutting just above the first pair of buds, typically one or two centimeters. The shoots that are birthed after pruning will bear flowers the following year.

For older plants: If the hydrangea plant has aged significantly and needs rejuvenation, a radical pruning technique can be applied. This involves cutting everything to a maximum height of 20 cm from the ground. Although this will result in no flowers in the current year, the plant will begin anew in the following year, flourishing beautifully. This severe pruning technique can be repeated every 4 to 6 years.
