Two questions most often ask buyers: why large hydrangeas do not bloom, and if they bloom, then why not in blue flowers?
To get guaranteed blossom, you need to try - after the first frosts, we will break the leaves, leave two tops. Remove the old branches - it stimulates the formation of powerful root shoots, cut down the weak shoots, they are unproductive and in winter are more often dying. In no case do not cut off the top kidneys - of which the largest inflorescences develop, and some varieties bloom exclusively on the tops. The remaining shoots neatly naughty to the ground, the lower, the better, do not isolate with the ground (this is a general error), the upper part of the bush should lie on the ground. The tops cover on top of Lutracil (spunbond, agricultural) and all the plant pumped off peat or ordinary earth (I take a bed, and in the spring it is referred to). Above the plant should be at least 10-15 cm of the Earth, and if you are not sure of the frost resistance of the variety, it can be covered with Loutrasil-60 from above. In fact, the process is not complicated, and the result exceeds expectations.

In the spring, the hindsya is found late, sometimes in the first days of June, because Flower kidneys are afraid of return freezers. But, if you live in the country, you can venture - dig, and in the threat of fooling, wind the bush Loutrasil in 2 layers. When removing the shelter, carefully leakes Lutrasil along with the Earth so as not to damage the buds, which by this time is usually already extended. Raise the shoots and at first we will pronounce Loutrasil, remove it in a rainy or cloudy day.

Large hydrangeas bloom very early, their inflorescences are scored already in early July, when the blizzard only gather with forces.

Why did blue grade hydrangea suddenly become pink? The fact is that hydrangees for the formation of blue inflorescences are needed by aluminum salts, for example, a means for painting hydrangea "Rainbow". It is necessary to make it in liquid form, but if it is rainy weather, you can burn around the bush on a teaspoon in several places, it will slowly dissolve and absorbed the plant. But aluminum works only on a very acidic land, so during the season it is necessary to make the soil acidification several times - 50 g of citric acid to dissolve in 10 liters of water and shed the land under the plant in a few approaches so that the solution has achieved even deep roots. So that the water does not spread - make a roller from the ground around the plants. These events should be carried out at the end of August-September, that is, at the time of the investment of floral kidney for the next year, but if you have been made at another time - it will not be worse, and then the blue inflorescences will appear in your hydrangea.
