Hydrangeas are not all created equal. Some plants can develop large, bushy blossoms without ever tossing over, but others need stakes to stand upright. Amy Enfield, a horticulture at ScottsMiracle-Gro, advises that the easiest way to determine whether your hydrangea needs staking is to examine it following a significant downpour. “Floppy hydrangeas might result from large blossoms and persistent rain. Therefore, it is a good idea to anchor your plants if the flowers cause the stems to bow to the ground under the weight of the rain.”
According to Enfield, your plant won’t often suffer if you don’t stake it. She does, however, caution against the possibility that fragile flowering stems may sustain injury if they are dragged down by the weight of many blossoms. If you want to cut flowers to enjoy indoors, it might also make them dirty, which is not ideal, she continues. Unsure whether or not to stake your hydrangeas? Here is the advise that Enfield and Venelin Dimitrov, a product manager at Burpee, had to offer.
How long should a hydrangea tree be staked?
To stake or not to stake is the question, with all due respect to Shakespeare and Hamlet. Too many gardeners opt for the former solution when staking trees. A young tree occasionally appreciates some mechanical assistance, but not as frequently as many gardeners think. Furthermore, staking usually only benefits a newly planted tree for a brief time, even when it does.
It can be more detrimental to stake a tree than beneficial. The trunk is strengthened by movement because it thickens and acquires a tapered shape from bottom to top. Root growth is also promoted by trunk movement. Therefore, despite the fact that staked trees may reach their full height more quickly than their un staked counterparts, they have weaker trunks and less established root systems.
Staking improperly exacerbates the issues with a young tree. A tree may girdle if it is attached to a stake too tightly, which could weaken or even kill the tree if the issue is not fixed right away. When a tree moves over a point where it is connected too closely to a stake, just like an unstaked trunk moves, the trunk above the tie thickens. The smooth movement of water and nutrients up and down the developing trunk is disrupted by this disparity in thickness. A plant can be tied down so tightly below the tie by a stiff stake and a tie that a strong wind can actually blow the tree’s top off. Another difficulty is when a tree is tied to a stake too loosely. The bark is continually rubbed, leaving scars that might never completely mend.
Should this tree be staked? Given the tree’s height, the root ball is small and will not be able to support the tree adequately. The author emphasizes how tall the tree needs to be to support a root ball this huge. So you should definitely bet this one.
Crowbar Hole
A trunk’s top must flex, but if the bottom flexes excessively, it may create a “crowbar hole,” where water and moisture may pool and possibly lead to rot. A stake can stop this motion.
Stakes allow a root ball to become a root system
A figure-eight-looped bicycle tire inner tube is fastened to the tree. It offers stable but adaptable support.
But sometimes staking a tree is beneficial. A young tree with an abundant leaf canopy and an abnormally small root ball will almost certainly need a stake. A tree can be staked in this manner to keep its root ball immobile in the ground. The roots can expand into the surrounding soil while the tree is temporarily stabilized artificially, anchoring the tree and providing it with more long-term, natural stability.
In addition to causing a root ball to sway back and forth instead of being stationary, strong winds flowing through a dense crown of leaves can also cause problems. This excessive motion could cause a “crowbar hole, a space that forms around a tree’s base where water gathers and may lead to root rot. I grab the trunk of a recently planted tree and rock it back and forth, looking for shifting soil at the base of the tree, to see whether the roots are moving. I can use staking to solve a problem if I notice movement. A stake will aid in maintaining the trunk’s position long enough for it to acquire the necessary thickness and taper to obstruct such movement. I regularly check the ground where the trunk emerges in the weeks and months after any tree is planted to see if a crowbar hole is forming.
Additionally, staking a tree might provide safety. A few well-placed stakes can stop a lawnmower from repeatedly striking a tree trunk and abrading its bark. Of course, you won’t need to mow close to the tree if you have mulched the area around it with wood chips or another form of mulch. A ring of mulch or pegs serves as a signal if you have planted a tree that is susceptible to soil compaction, such as a sugar maple or white oak “Stay off this area. A trunk needs at least three stakes encircling it to be protected.
A well-staked tree should be able to move in place
Any young tree support should allow for some trunk movement as well as unrestricted top movement without producing abrasion where the tie makes contact. The top of the tree won’t be able to move enough if a tie is positioned too high (more than two-thirds of the way up the trunk). Use just one tie per stake to allow the lowest part of the trunk to move as it should.
The optimum material for a tie is elastic because it permits movement at and below the point of attachment while maintaining a firm enough hold on the trunk to prevent abrasion. An example of this would be the inner tube of a bicycle tire. Nylon stockings and elastic webbing are additional suitable tying materials. It is recommended to tie any of these materials in a figure-eight loop between the trunk and the stake to prevent the trunk from rubbing against it. Because it can’t grab the trunk securely without eventually girdling it, the conventional method of tying involves utilizing wire that has been cushioned with a length of garden hose.
Wooden posts, metal pipes, and lengths of metal rebar make excellent stake materials. I’ve also used fiberglass posts that are offered for use with electric fence to stake down small trees. These posts have the extra benefit of being flexible itself. Stakes should be sturdy enough to offer whatever support is required, but they shouldn’t be too big or positioned so that the trunk of a tree is overly shadowed. In the absence of this, the trunk will inevitably sag away from the stake.
For a little tree with a trunk smaller than a couple of inches in diameter, one stake may be sufficient. Use two or three stakes and tie each one to the trunk independently for a larger tree with a diameter of up to 4 inches.
Stakes should be temporary, the more so the better
Even when staking is required, it is best to remove the stakes as soon as possible so that the plant may grow a sturdy trunk and root system. I usually take the pegs out of small trees after a year, but larger trees may need them left in place for two years. By moving the tree’s trunk and looking to see if the root ball moves, you can determine if a stake can be removed. The stake is no longer necessary if there is no movement. But there are some: For instance, some dwarf apple trees need to be staked periodically throughout their lives. However, for the majority of trees, forgetting about it, allowing ties perhaps encircle a trunk, or simply keeping the stakes in place for too long might impede the growth of a solid trunk.

How frequently do hydrangeas need to be watered?
Although the hydrangea’s leaves and flowers seem delicate, little careful care is actually needed for them. Everything you need to know about caring for hydrangeas is provided in these recommendations.
- Over the course of the growing season, water at a rate of 1 inch per week. To promote root growth, deeply water three times each week. All varieties of hydrangeas benefit from constant moisture, but bigleaf and smooth hydrangeas need more water. To water thoroughly while keeping moisture off the flowers and leaves, use a soaker hose. Hydrangeas won’t wilt as much if they are watered early in the day on hot days.
- To keep the soil around your hydrangeas cool and moist, add mulch. Over time, an organic mulch decomposes, supplying nutrients and enhancing soil texture.
- Apply fertilizer according to the type of hydrangeas you have. Every variety has varied requirements and will profit from applying fertilizer at various times. A soil test is the most effective tool for determining your fertility requirements.
- In March, May, and June, bigleaf hydrangeas require numerous mild fertilizer applications.
- Two applications in April and June work best for oakleaf and panicle hydrangeas.
- The only time smooth hydrangea plants require fertilizing is in the late winter.
- By selecting cultivars with resistant characteristics, you can avoid pests and diseases. Hydrangeas can have leaf spots, bight, wilt, and powdery mildew. Although they are uncommon on hydrangeas, pests might arise when the plants are under stress. Aphids, leaf tiers, and red spider mites are examples of potential pests. Your best line of defense is to properly care for hydrangeas.
Why wilt hydrangeas so quickly?
Because of their thick, woody branches and sticky sap production, hydrangeas are sometimes among the first flowers in an arrangement to begin to appear dejected. This is because it might be difficult for hydrangeas to absorb enough moisture in a vase to cover the entire flower. But since hydrangeas are one of the few plants that can absorb moisture through their florets, completely soaking wilting blooms in water and letting them sit for a few hours to rehydrate will revive them.
If you have a few stems of cut hydrangeas that you’re not quite ready to throw away yet, it might be worth a try to revive them. The efficacy of this hack, according to Seattle-based floral designer Rizanio Reyes, “depends on when the flowers were cut and how long they’ve been in a box in cold storage post-harvest,” among other things. Freshly cut, somewhat wilted hydrangeas will probably be easier to revive than ones that have been in storage for a while (though it’s still worth a shot!). According to Reyes, “I’ve done this with some degree of success, but it’s never 100%,”
Avoid the temptation to use this method to save other popular cut flowers from withering, such as roses, peonies, or tulips. Soaking them will just hasten their decay and wilting because they lack hydrangeas’ capacity to absorb moisture through the blossoms.
Why are my hydrangea’s leaves curling?
The extravagant, vivid blossoms of hydrangea shrubs stand out against the background of lush, green foliage. Therefore, when something is off with the leaves, it is more than a little noticeable.
Curling leaves might be foreboding, but why such a drastic change in their outward appearance?
Hydrangea leaves can curl for a variety of reasons, including over- or under-watering, dry soil conditions, harsh weather, nutrient deficiencies, insect and fungal damage, and dry soil conditions. Each of them results in weakening plant tissue and cell death, which causes curled, twisted leaves.
Leaf curl can affect the entire leaf or just a small portion of it, and it frequently comes with accompanying symptoms like discoloration and texture changes.
We’ve provided a list of the typical causes, solutions, and prevention advice to assist you in troubleshooting them.
How can you keep hydrangeas safe from torrential rain?
- Choose a hydrangea cultivar that thrives in your growing environment.
- Keep potted hydrangeas out of bad weather, such as torrential downpours or windstorms.
- To support outdoor hydrangeas, use fences, trellises, tomato cages, or stakes.
- Regularly cut down older, weaker growth and remove dead blooms and branches.
- Make sure to fertilize and completely mulch newly planted hydrangeas.
