Regarding this, are hydrangea trees easy to grow?

Of all the small, flowering trees, hydrangea trees are the most dramatic when in full bloom.

Should I deadhead my hydrangea tree?

Removing Spent Blooms on Hydrangea

How do you keep a hydrangea tree small?


Pinch out the growing tips of new wood hydrangeas when they are a few inches tall in early spring. The plant develops additional side shoots, which will be shorter with more, but smaller blooms. You can repeat the process through midspring as the plant grows, depending on how much smaller you want the plant to be.

Can you split a hydrangea?

If you don't see any shoots or are getting pieces without roots, entire hydrangea plants can be dug and split into two or more pieces. The best time to divide bigleaf hydrangeas is very early spring, just as new green buds are starting to swell and open along the stems.

What happens if you don't prune hydrangeas?

Hydrangeas that bloom on old wood do not need pruning and are better off for it. If you leave them alone, they'll bloom more profusely the next season. But go ahead and gently thin or deadhead. Just remember new growth may come, but that new growth will be without blooms next season.

Do hydrangeas come back every year?


Since they bloom on previous years' growth AND the new season's growth, you can leave them all winter long to achieve double the blooms next spring. Do NOT prune the hydrangea back in fall. Mound the mulch or leaves around your plants at least 12” high to protect the flower buds that will bloom early next year.

Are coffee grounds good for hydrangea?

If you're growing hydrangeas, use coffee grounds to affect their color. Coffee grounds add extra acidity to the soil around hydrangeas. On a chemical level, this increased acidity makes it easier for the plant to absorb naturally occurring aluminum in the dirt. The effect is pretty blue clusters of flowers.

What can you plant next to hydrangeas?

It is also effective to pick plants with very different foliage for companions for hydrangea, such as lacy, delicate ferns. Or consider the delicate evergreen 'Soft Caress' mahonia for hydrangea companion plants. The feathery texture of the foliage contrasts nicely with the wide hydrangea leaves.

Can you grow hydrangeas in pots?

  4. Prune stems back in early spring, just before new growth emerges.

Do hydrangeas lose their leaves in winter?
