Bigleaf hydrangeas grow just fine without any pruning, and making your cuts at the wrong time can actually remove the flower buds you are hoping to get. The flower buds are on the growth rings of the wood, which is why bigleaf hydrangeas bloom on old wood. If you cut too early, you may not get the flowers you’re looking for.
The best time to prune your bigleaf is in the fall, when the buds will be ready to bloom. This is also the time when they are most susceptible to frost damage, so it’s a good idea to keep them in a cool, dry place until then.

What month should I prune my hydrangea?
Trimming should be done immediately after flowering stops in summer, but no later than August 1. If you want to cut off new buds, do not do it during the fall, winter, or spring.
When leaves emerge in the spring, tip-pruning the branches can encourage multiple, smaller flower heads. If your plants look like they’re ready to be trimmed, they are. If they don’t look ready, you may need to wait until the next growing season.
Do bigleaf hydrangeas bloom on old wood?
Most gardeners are familiar with the bigleaf hydrangeas. Also called mopheads or lacecaps, bigleaf hydrangeas are characterized by shiny, dark green foliage and large colorful blooms. They generally bloom on old wood and can be difficult to find in the garden.
The flowers of this plant are very fragrant and are often used in perfumes. The flowers are also used as a food source for many animals, including rabbits, squirrels, raccoons, birds, and other small mammals.
Do you deadhead bigleaf hydrangea?
“Bigleaf hydrangeas, such as Endless Summer, should be deadheaded when the first set of flowers sprouts from last year’s growth in the spring, as it eliminates the faded flowers before they have a chance to bloom,” .
Should I cut off Brown hydrangea blooms?
The blooms on your shrubs are turning brown. No need to worry – this is simply a sign that it’s time to remove the flowers, a process called deadheading. When you deadhead hydrangeas, you’re not harming the plants, but you’re removing the pollen and nectar that the plant needs to survive.
When should I cut back my mophead?
The mophead and lacecap hydrangeas can be trimmed right after flowering to make room for new growth. Hybridization is a process in which two or more plants are crossed to produce a new plant that is genetically identical to one of the parent plants.
Hybridization occurs when a plant is crossed with another plant in the same family, such as a cross between a daffodil and a tulip, or a hybrid between two species of dandelion. Hybrids can also be produced by crossing two plants that are genetically different from one another.
For example, if one plant has a yellow flower and the other a red flower, the yellow plant could be cross-pollinated with the red plant, resulting in an orange flower.
How do you prepare bigleaf hydrangeas for winter?
The simplest method is to mound shredded leaves or bark mulch around the base of the plant to about 12 inches or so. If you want to uncover plants in the spring, you need to put the mulch mound in place late in the fall. If you don’t have the time or space to do this, you can plant the plants directly in the soil.
This is a good option if you have a lot of space in your garden, but it’s not as easy as it sounds. You’ll need to dig a hole about 6 to 8 inches deep and fill it with a layer of soil that’s about 1/2 inch deep. Then you’ll dig another hole, this time about 3 to 4 feet deep, that will be about the same depth as the first hole.
Fill the second hole with soil about an inch deeper than the one you just dug. Finally, fill the third and fourth holes with about 2 to 3 inches of water-soluble soil, such as peat moss, perlite, or vermiculite. The soil should be moist but not soggy.
What does a bigleaf hydrangea look like?
The leaves of the bigleaf hydrangeas are about 6” long and 3” wide. The leaves are thick, shiny and heart-shaped with short stems. Reduced flowering can be caused by bigleaf hydrangeas preferring shade but not too much. July, they prefer moist and well-drained soil. Hybridization is a common practice in the nursery industry. Hybrids are created by cross-pollinating two or more species of the same genus.
This is done to increase the variety of plants that can be grown in a given area. Hybridization can also be used to create new species that are not native to North America. In this case, the hybrid plant is grown from seeds that have been crossed with a native species.
Do bigleaf hydrangeas rebloom?
Bigleaf hydrangeas that bloom on old and new wood are known as reblooming, or remontant, hydrangeas, since they bloom first on their old wood, then after a brief rest for some vegetative growth, create flower buds on that new growth.
In the spring, when the trees are ready to bloom, they are cut back to their original size, and the buds are removed, leaving the tree in a dormant state until the next spring. This is the time of year when most of the re-blooming takes place.
In the fall, after the leaves have turned brown and fallen off, the old growth is cut down and replaced with new, healthy wood.
