Care of Hydrangea macrophilla: Calendar of Works

For a start, it should be noted that care for Hydrangea macrophilla differs significantly from the farming Hydrangea arborescens. If these species feel great in our Northern gardens, where they successfully winter without any shelter, the capricious beauties of macrophiles need a special approach. The biological features of Hydrangea macrophilla are that they are flowering buds in the mass (on the repair varieties later) lay on the shoots of last year, which forces us to prepare them especially carefully for the winter, with its severe frosts and prolonged thaws.

What unites the various hydrangeas is that they all belong to plants — acidophiles, lovers of acidic soils. In addition, they are quite “voracious”, need abundant and regular food, and are sensitive to the lack of sunlight. Now consider what are the requirements macrofile to the gardener that you need in order to provide stable hydrangeas bloom.


Winter Hydrangea macrophilla under the binding cover. Leave them for the winter without insulation can only be in the South. But there are sometimes short-term frosts. In these cases, the bushes should throw nonwoven fabric to protect the flower buds from the threat of freezing. If this happens, flowering in the current season will not.


With the onset of stable heat (calendar dates do not matter, spring may be early or late, should be guided only by the weather) begin to release hydrangeas from shelter, removing it gradually. But!

So do not rush to open the bushes fully: at hand must be covering material that is easy again to throw on plants. After all, even a light short-term cooling to sub-zero temperatures is enough to destroy the flower buds.

After the Bush is finally opened, its branches should be straightened, as they are pretty deformed during the winter in a bent state. To do this, fix the branches in a vertical position, tying them to pegs. This is followed by spring pruning.


It should be emphasized that it is fundamentally different from pruning tree and paniculate varieties. If the latter are usually subjected to a fairly radical pruning, which causes them to branch and provides a lush flowering, then the macrophiles only slightly cut off the dry frozen tops, lighten the center of the Bush, remove the broken branches, trying to give the plant a harmonious spherical shape. And in any case do not make a low trim, as thus removed flower buds.

In irrigation water to add humates or diluted in the ratio 1:10 green fertilizer (a solution of fermented stinging nettle, dandelions, mowed lawn grass). Very well all hydrangeas respond to watering acidified water (1 tablespoon of citric acid in a bucket of water). In addition, you can use a special liquid acidifying agents (e.g., vitacimin) which are commercially available, using them strictly according to instructions.

In the planting pit should add superphosphate or bone meal as a source of phosphorus, potassium fertilizer (a handful). I draw your attention that it is absolutely impossible to use wood ash and fertilizers containing chlorine when planting hydrangeas of any kind.
