However, note that the first two should be trimmed only superficially, only removing the old inflorescences. Why? Because flower buds in these species already develop in the previous year, so shrubs subjected to strong pruning would have nothing to bloom on.Shrubs not cut or cut irregularly lose their vitality and require radical rejuvenating treatment.
The hairy hydrangea requires a different treatment. It is a species that reaches a height of approx. 2 m and does not require regular pruning.Moreover, hairy hydrangea does not tolerate rejuvenating pruning at all. It is pruned almost sporadically to remove single, old, dry shoots. This shrub rejuvenates itself through stolons.
- The Bush Hydrangea Hydrangea arborescens also blooms without regular pruning. However, flowering is longer and more abundant after pruning. Shorten the faded flower shoots by half, cut the dead ones above the ground;
- Regularly prune the Hydrangea macrophylla garden hydrangea, because only then the bush blooms profusely.In spring we remove all faded inflorescences.Old, diseased and damaged shoots are cut just above the ground;
- Bouquet hydrangea Hydrangea paniculata has a highly branched base, from which many new flower panicles grow every year.Shoots of this species are cut to woody parts, trying to leave as many plugs with buds as possible. Remove dead shoots. We cut bushes that have not been pruned for years in order to rejuvenate them.
