The strength and timing of ornamental shrubs pruning depends on their flowering time. The hydrangea is cut a little differently.

Pruning flowering hydrangeas from previous year’s buds

Garden hydrangea, hydrangea serrata and oak-leaved hydrangea bloom on last year’s shoots, which means that at the beginning of the year they already have buds with inflorescences.

At the end of winter or early spring, only cut out their dry inflorescences, just above the first pair of buds. You should perform translucent cutting every 4 years. These hydrangeas belong to the group of plants that do not require annual maintenance pruning.

Pruning of flowering hydrangeas on current year’s shoots

The situation is different for such species as bouquet hydrangea and shrub hydrangea, which attract a large group of gardeners. No wonder they are extremely easy to grow, and if you take good care of them, they will repay you with lush flowers.

These plants bloom on current year’s shoots. In spring, when the shrubs have not developed leaves yet, trim the plants low. Cut the shrub hydrangea to a height of 15-20 cm. The bouquet hydrangea to 2/3 of its length, above the 3 or 4 buds, and cut the weaker shoots in half. Cut out all thin shoots.

Hydrangeas pruned in this way will produce strong shoots with lush flowers from the buds left behind.

After cutting the hydrangea, you can cover the soil around the plant a layer of compost, gently mixed with soil.

It is also worth spreading the shredded manure under the plants, mulching the shrub within the root collar. Then, during the growth, feed the hydrangeas with compound fertilizers for ornamental shrubs.
