Hydrangea Blue Diamond plant care

Hydrangea Blue Diamond care is simply about getting a few easy things right so the plant thrives. they prefer a sheltered spot in either full sun or part shade. Only in very hot climates should full sun positions be avoided. A well-drained, fertile soil is crucial. Adding organic matter like compost into the soil during planting will help with soil fertility. They prefer a moist soil so consistent watering is essential, especially during dry periods but be careful to avoid overwatering as this can lead to root rot. Applying shrub fertiliser in spring will keep the Hydrangea Blue Diamond plants well-fed for the year. Prune in late winter or early spring and continue to remove spent flowers to encourage further blooming. Applying mulch around the base of the plant helps retain moisture, regulate soil temperature, and suppress weeds. Monitor for pests like aphids and diseases like powdery mildew and treat as needed with appropriate measures.

How to the prune the Hydrangea Blue Diamond variety

The Hydrangea Blue Diamond variety is pruned each winter to contain growth and encourage fresh, new growth that will bear flowers. The Plant Company recommends they are pruned back to a low crown which has short stems (about 10 cm long) with at least two buds on each stem remaining. Any dead stems should also be removed at this time, along with stems that are criss-crossing or show disease. Young plants will generally be left with five stems whereas older plants can have 10-20 stems remaining. These can be thinned back to 15 if desired which will help produce bigger flower heads. Longer stems can be left on younger plants while they are establishing. In general, the harder the plant is pruned back, the more contained it will grow the next season. Flowering can be affected with hard pruning but that is more likely to cause delayed flowering only. A mistake often made with pruning the Hydrangea Blue Diamond variety is to not prune the plants hard enough. This error results in a woodier plant and a much larger plant that can be difficult to contain.

Can the Hydrangea Blue Diamond be grown as a hedge?

The Blue Diamond Hydrangea is often grown as an informal hedge. That is, a hedge this is minimally trimmed, if at all, such that their natural, rounded shape is preserved to a degree. To create an informal hedge, space the Hydrangea plants 70-90 cm apart. The Blue Diamond hedge can be trimmed as little or as much as you want given it is the informality you are wanting. The Plant Company recommends that informal hedges are trimmed with a little and often approach so they become bushy yet still contained.
