Hydrangeas are plants with very long blooms, they have few rivals in our gardens, and they are also very popular on the terrace. They vegetate late, but when they begin to bloom, they punctuate the space with magnificent colors. There are four secrets that few know for having lush hydrangeas and giant flowers on the terrace. Let’s find out today with the Bag Projection Garden Experts.

Beware of active limestone

Acid soil, abundant and not hard water, reasoned pruning, partial sun exposure are the right moves to ensure wonderful hydrangeas.

The soil must be acidic, because these are acidophilic plants that fear active limestone. Otherwise a strong chlorosis is triggered, that is to say a discoloration of the leaves that saddens us. This is associated with an arrest of development and a progressive wasting.

The water must be abundant and not calcareous: they are always thirsty plants, but too much active limestone damages them. Those who live in the plains must provide to acidulate the water by adding a spoonful of vinegar every 10 liters. Better to let it rest before watering, because the calcium salts that harden the water must precipitate.

It is precisely the acidity that regulates the spectacular manifestation of the blue color in hydrangeas. If the water is too limestone, it will only take a few months to find it pink again.

Pruning must be reasoned. They had to be done in late winter, preferably in February, preferably above the buds and facing the outside of the plant. In this way the new shoot can generate new branches outside the canopy.

In this period you have to work a lot on exposure, avoiding full sun in the hottest hours. And this is because hydrangea leaves curl up easily and the flowers wither early.

The maxi red hydrangeas

If you like maxi hydrangeas, you should prefer the macrophylla ripple, a recently born hybrid variety, which has large two-colored inflorescences and reaches a height of 120 cm.

It begins to bloom in this month and reaches its peak in July. The shape of the inflorescence is globular and the color of the flowers is only marginally affected by the pH of the soil, because blue is absent. The flower is white, with an evident pink border. The color turns to an intense red.
