Do hydrangeas need a lot of water?
Hydrangea Plant Care: Water Requirements Hydrangeas absorb water quickly. Keep the soil of hydrangea plants evenly moist and well drained, though this can take watering your plants possibly more than once per day. Hydrangeas grown outdoors as shrubs and garden plants do not need as much attention to watering.
Do Hydrangeas like sun or shade?
Most hydrangeas thrive in rich, porous, somewhat moist soils. Add compost to enrich poor soil. They prefer full sun in the morning, with some afternoon shade; however, many will grow and bloom in partial shade.
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.
Should I cut off dead hydrangea blooms?
While removing the faded blossoms is not necessary, if you want to clean up the plant you can snip the stems just below the dying flowers, above the developing buds on the stem. Do not prune after August 1; the shrub needs time to develop new flower buds on the old wood.
Do hydrangeas attract bees?
Unfortunately, the very common and showy Mophead hydrangeas, or Hydrangea macrophylla hortensis (some seen above) do not feed the bees or other pollinators because their flowers are sterile. But there are other hydrangeas that feed the bees and pollinators while also being great plants for the garden.
How do you keep hydrangeas from spreading?
Edge the area you want to keep intact. Use a sharp spade to cut through the rhizomes (underground root-like stems) to disconnect the hydrangeas you want to keep from those you want to remove. Continually prune the unwanted stems to ground level whenever they appear. Over time these stems should weaken and die.
How often should I water hydrangeas outside?
The hydrangea should be watered thoroughly at least 3 times a week. Always water the plant all the way around the container, not just in one place. Water should come out the bottom of the pot. Never let it sit in water which will cause the roots to rot away.
Should I prune my hydrangea tree?
Pruning in late fall or early spring before new growth begins will bring new blooms all summer. Big Leaf and Oakleaf hydrangeas should be pruned no later than early fall, otherwise you may cut off buds preventing any blooms come summer. For these types of hydrangeas, it’s best to prune immediately after flowering.
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.

What can you plant next to hydrangeas?

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.
Do hydrangeas lose their leaves in winter?
