When should I prune my hydrangeas? is one of the most often asked gardening topics. We all have a tendency to want to hurry outside with the clippers and start hacking away when those billowy large flowers change from cheerful blues, purples, pinks, reds, and whites to uninteresting browns.
When to Cut Back Hydrangeas
The timing will vary according on the variety of hydrangea you have. First of all, be aware that hydrangeas do not require pruning unless the shrub has become unruly or too big for its location and requires some shaping up. Otherwise, simply deadhead wasted blooms and remove any dead branches from the plant.
How to Prune Hydrangeas02:07
But if you do decide to prune one, bear in mind to time it so that it blooms on old wood or new wood depending on the species of hydrangea you have.
If you wait too long, you can chop off the buds that are developing on old wood (stems from the year before the current summer), which would prevent flowers from blooming the following spring. Therefore, as soon as the flowers on these bushes have faded, they should be clipped.
The shrub should be clipped in the early spring before that new growth appears, but, if the shrub flowers on fresh wood (stems generated during the current season), which means that its buds are set inside the season.
Should I remove the hydrangea’s dead flowers?
Your hydrangea shrubs’ blossoms appear to be withering or turning brown. No need to worry—this is merely a signal that it’s time to deadhead—remove the blossoms from the plant.
Deadheading hydrangeas doesn’t cause any damage to the plants at all. Flowering shrubs stop producing seeds when the spent blooms are removed, and instead focus their efforts on developing their roots and leaves. You will be doing your hydrangeas a favor by deadheading because this strengthens and makes plants healthier.
When may I remove the hydrangea’s dead blooms?
These are your macrophylla hydrangeas, also known as mophead and lacecap, which come in purple, pink, and blue. They also include hydrangeas with oak-shaped leaves. While reblooming kinds flower twice, some cultivars only bloom once per season on stems from the previous year (old wood).
The initial set of hydrangea blossoms should be deadheaded as soon as they start to turn brown and dry. Cut the stem immediately above the first set of leaves and below the flower head. When this second set starts to fade, you can deadhead once again for reblooming varieties, but only until about mid-August. Your hydrangeas will then produce buds for the flowers of the next year; you don’t want to unintentionally cut these off. After the summer has ended, dried flower heads can remain on the shrubs to add visual interest over the winter.
Can dried hydrangea blooms be cut?
Hydrangeas dry best when left on the bush after their prime and are trimmed when they start to naturally dry out at the end of the season. According to Marzec, if you remove your stems too soon, they may shrivel up. He advises waiting until late summer or even early October for late-blooming kinds. Pay particular attention to the petals, which will start to fold under as the colors fade, and the leaves, which start to feel papery and less fresh, she advises. According to Chris Link, co-owner of Nebraska-based online nursery Plant Addicts, the color of the bloom is another important consideration. Most hydrangea blooms begin as one hue, such as green or white, and change to another, such as pink or red, according to him. Simply clip the blossom when it is the desired shade of color, but before it becomes brown.
Cut flowers with stems that are between 12 and 18 inches in length for the greatest displays, and make sure to remove any leaves before drying. Link advises against trimming stems too short on some hydrangeas that bloom on old wood because doing so could affect the flowers of the following year. This would only be concerning if you removed the blooms extremely late in the year because the flowers would probably already be brown by then.
Do I need to remove the dead stems from my hydrangea?
Remove stems that are crossing or dead. Cut these stems just above the soil line. Keep in mind that old wood is where buds for blooms are generated, thus the more old wood you remove, the less blossoms will appear in the spring and summer. Remove up to one-third of the older living stems from the hydrangea each summer, cutting them all the way to the ground.
What occurs if hydrangeas are not deadheaded?
Deadheading too-tall hydrangeas can occasionally be challenging. Your other option is to keep them on if you don’t have the skills to reach spent flowers or all of the spent blooms. And you can do that without suffering too much harm.
Simply omit deadheading hydrangeas, and your plant won’t suffer. At least nothing major enough to need worrying about.
Your hydrangea might not produce as many or as large of blooms as it would have if the spent blooms had been removed. It will nevertheless continue to bloom.
Having said that, you can think about pruning hydrangeas that have gotten too tall in order to make them smaller and easier to handle.
This will make it simpler for you to maintain the tidy appearance of your hydrangeas. Additionally, it will make it simpler to remove spent blooms from plants and promote future blooms with greater vigor.
Should I remove the spring blooms of my brown hydrangea?
Pruning is not typically thought of as one of the many gardening activities that may be done in the fall, despite the fact that there are several. It can be difficult to cultivate hydrangeas successfully in New Hampshire, and if you want your plants to blossom, there is frequently very little room for error in pruning.
Wait until Spring to prune hydrangeas
In New Hampshire, hydrangeas come in a variety of kinds, and each one has quite distinct growth patterns and pruning needs. Some plants only produce flowers on fresh growth, while others mostly produce flower buds on older wood. In any case, it is better to postpone all hydrangea pruning until spring. Hydrangeas, as with all other trees and shrubs, go dormant in the fall. Not much new growth is produced by them until the next spring. As new growth is more vulnerable to harsh cold at the location of wounds, plants that have been trimmed now run a higher risk of winter damage. Additionally, fall pruning may lessen the quantity of June blooms.
Considerations for pruning hydrangea species commonly grown in New Hampshire gardens
The gigantic blue mopheads or lacecaps known as bigleaf hydrangeas (Hydrangea macrophylla), which are familiar to most gardeners, form their flower heads at the tips of stems on old wood from the previous year. Although lower buds along the stem have the capacity to grow blooms as well, the hydrangea’s blossoming potential is decreased if those buds are died or damaged throughout the winter. Wait until new growth sprouts in the spring before pruning your bigleaf hydrangeas. Approximately 1/4 inch above the first group of live buds, prune the plant. A hint: the interior of living stems will be green, whereas the interior of dead stems will be brown. Cut completely dead stems flush with the base.
The three other hydrangea species that are frequently planted in Fresh Hampshire—oakleaf (H. quercifolia), panicle (H. paniculata), and smooth—all bloom on new growth. Before the emergence of the leaves in the late winter and early spring, remove wasted flowers and prune the plant to improve its general structure and habit.
In conclusion, there are a ton of other activities you can engage in to stay occupied in the garden during fall. Save the spring for hydrangea pruning.
How may dried hydrangeas be prevented from disintegrating?
Yes, I am aware that using water to dry hydrangeas seems a little backwards, but I assure you that it is the simplest method. Thus, this is what you do:
- Cut:
- Cut the quantity of hydrangeas you intend to dry or incorporate into your current cut flower design.
- Make them 12 to 18 long. Once I get all the stems together, I normally make the initial cut longer than that and depending on where it would preserve the shrub in good condition.
- De-Leaf:
- Simply move your hand down the stem, pulling off the leaves as you go, by grasping it at the top just below the bloom. I suppose you could go up, but if you do, you run the risk of picking up too much speed and damaging the bloom as well.
- I frequently conduct my de-leafing in the garden, leaving the leaves to act as natural compost in my beds. If you do it inside, though, stripping your stems directly over a garbage can will make cleanup much simpler.
- Fill a vase with:
- Simply arrange your hydrangeas like you would any other flower arrangement, which will require some trial and error in placement if you want to enjoy them before they dry—I don’t know why you wouldn’t.
- I typically hold each stalk in one hand while moving the others such that the flowers with the straightest upward faces are in the center and the smaller and/or droopier ones are on the sides. I then make my final selection, keeping them all at the same level, after gauging their height in relation to the vase.
- The bottoms of your stems should then be pounded with a hammer to aid in their water absorption, however I’ve never tried it; feel free to.
- Just before placing flowers in the vase, I twist tie or rubber band the stems to secure them in place.
- Adjust the arrangement of the blossoms after placing them in a tall vase strong enough to hold the length of the stems.
- Insert Water:
- I’d advise adding the water before the flowers if your faucet doesn’t extend with a hose. Do it either way if you have one of those posh faucets.
- Usually, I would fill the vase about half and three quarters full, making sure that all of the stems were submerged completely.
- Dry:
- You might have to keep adding water until the flowers are completely dry, depending on how the blooms were when you started the drying process. If not, I’ve seen that they wilt and then dry wilted, which isn’t very attractive.
- Therefore, maintain watering if the flowers are still quite supple. You can stop watering them once they have dried out and feel and look like paper.
- You can enjoy your lovely dried flower arrangement for many years once a few weeks have passed. On our mantel, we really have a pair that has been there for about 9 years.
- Spray:
- When your hydrangeas are completely dry, mist them with hairspray aerosol (sorry, aerosol spray just works better than the pump spray kind…it just does).
- I used to believe that this was done to coat the blooms in order to keep their color for a little while longer. But now I believe it’s only to keep the florets together, making it less likely that they will fall off when you brush up against them and make a big mess.
How are dried hydrangea blooms kept fresh?
Place the vase away from direct sunlight in a cool location. The water in the vase will aid in slowing the drying process, which will improve the preservation of the bloom. They will be fully dried and endure forever once the water has been removed.
Prepare the Flowers
Although it may seem contradictory to use water to dry flowers, hydrangeas benefit from a gentle desiccation process that keeps their color and shape (even the stems end up sturdier when dried this way).
Using a pair of pruning shears, cut each blossom on the angled side, leaving a stem length of between 12 and 18 inches. Take off every leaf from the stalk.
Place the Cut Flowers in Water
After that, arrange your freshly cut flowers in a vase, fill it about halfway with water, and set it aside in a cool location away from the sun. Keep in mind that hydrangea dry best when given room to “breathe,” so take care not to overcrowd your vase with stems.
Allow the vase’s water to totally dry out. After this procedure, which typically lasts two to three weeks, your hydrangeas should feel dry to the touch and the stems should simply snap off. They are now prepared for use.
Use Your Dried Hydrangeas
Your dried hydrangeas can be displayed in a variety of artistic ways. Although they look lovely on their own in a vase, you can also incorporate them into seasonal wreaths or use them in window boxes with other dried flowers. Getting hitched in the autumn? Even your bridal floral arrangements can incorporate them.
In the summer, do you deadhead hydrangeas?
You ought to be deadheading the spent flowers all through the flowering season. Just above the first pair of leaves that are opposite one another, follow the stem down. You should cut this off to promote new growth.
Your hydrangeas will look better overall and be ready for the next year if you deadhead them. Early April is when the hydrangea growing season begins. The shrub’s longer branches can be clipped by gardeners to display the hydrangea blossoms in vases. Early summer is the ideal time to deadhead to encourage growth.
Your hydrangea is most likely developing new buds for the following year after August. It’s a strong, positive plant! Before cutting, run your fingertips down the stem to feel for any bulging new flower buds. Make sure to avoid any bumps you feel or see by cutting safely over them.
