An often asked question is whether one can cut hydrangeas - the answer is:
'of course' !
But in this case the usual section advice collides with the reality. Hydrangeas tend always to produce longer and longer drives if you stick to the classic rules to cut them. The result is a huge bush with long tentacles that quite like to break sometimes. For example in winter under snow load, at stormy times, or when a fat bird sits on a branch.
But how does the classic cut of hydrangeas look like? The general instruction is to cut down the the dried flowers in the spring until the the
most well-developed pair of buds. These are according to the principle of the liquid balance almost always the outermost or uppermost buds. Consequently, these branches are getting longer from year to year, because of course the woody base also grows. To avoid that effect there are two solutions:
Either you cut the hydrangea every 3 to 4 years back radically, eg until about the third or fourth pair of eyes (counted from the ground). Then there is indeed a compact growth habit, but this year the hydrangea but will probably not produce any blooms. In fact you can very often see hydrangeas in many gardens that seem to need such a radical cut.
Assuming that the growth form of the hydrangea is still ok (or again, in the following year after a radical section), the second variant is a bit gentler. Rather than to cut the hydrangeas above the most developed pair of buds you can choose the second or third best. So the hydrangea remains permanently in shape, but flourishes perhaps a little later.
Already dry hydrangea flowers can be cut at any time. Already in the autumn, for example, to avoid that they break under the weight of the snow. But a cut in the spring is best for the plant and gardener. On the one hand because the plants have already redeveloped their defenses against deseases and on the other hand, because it can be best seen where to cut. The new drives can be easily recognized and the dead or frozen wood can of course only be removed until after the coldness of winter.
Garden Tip : You don't have to throw away old and faded hydrangea. If you colour them by spray they create a beautiful dry bouquet.
