- Cut two to four cuttings from the green stem tips of the unflowered stems using clean, sharp pruners.
- The lower portion of the cutting should be leaf-free.
- Rooting hormone should be applied to the cutting’s tip.
- Put the cuttings in sterile, wet potting soil.
How are oakleaf hydrangeas rooted in water?
Large oakleaf hydrangeas (Hydrangea quercifolia) are endemic to the southern US and grow on damp, acidic soil in partial shade. In contrast to the mophead flowers found on the majority of ornamental hydrangeas, the oakleaf hydrangea bears long panicles of flowers. Oakleaf hydrangeas have the unusual characteristic that additional plants, or suckers, sprout from the plant’s surrounding roots. These suckers can be cut off from the mother plant and moved to a pot or another area of the garden. Taking a cutting and rerooting it in sterile potting soil or another planting medium is another method for growing more oakleaf hydrangea plants.
Early in the spring, take a 6-inch clipping from a non-blooming stem that has a swelling bud on the end and two tiny leaves coming from the node beneath the new bud. Place right away in a water-filled container. No longer than a few seconds should the cut end of the cutting be exposed to air.

Clean planting material should be prepared. Use fresh potting soil, sand, or a sterile potting combination created especially for the purpose of helping plants take root. Fertilizers shouldn’t be present in the potting mixture. Because it includes pathogens that will attack the new roots that grow on the oakleaf hydrangea cutting, avoid using garden soil or old potting soil. Fill the flower pot with potting soil, then wet the soil with water. Drain; leave.
With a sharp cutting instrument, trim the oakleaf hydrangea stem just below the leaf node that is beneath the node that is home to the two little leaves. Your cutting will be roughly 3–4 inches long as a result. At the leaf node that you cut underneath, pull off the buds or leaves in a downward motion. As a result, the rooting hormone will adhere to the place where new roots will eventually grow by slightly damaging the stem.

Dip the cut end of the stem in water, then cover it with powdered rooting hormone, covering the damaged leaf nodes where the leaves or buds had been removed.
With your finger, poke a hole in the planting media. The soil should be half way between the cut end of the oakleaf hydrangea stem cutting and the two little leaves you left on it. Insert the cutting into the hole. There should only be the top bud, two little leaves, and leaves above the soil line. Make sure the damaged nodes are covered by soil or located directly above the incision. Gently tuck the cut end inside the planting medium. Place the container in a warm (75–85°F) location and maintain a steady moisture level in the soil for 6–8 weeks or until the cutting begins to actively grow.

Is it possible to grow oakleaf hydrangeas in water?
Hydrangeas can be propagated by taking cuttings from the plants and allowing them to root in water, but this is difficult.
The main issue with cuttings from your oakleaf hydrangea plant and re-rooting them in water is that hydrangea roots do not thrive when submerged in water.
When planted immediately into the ground after rooting in water, hydrangea cuttings will quickly perish. Instead, they do best in moist soil with good drainage.
Can oakleaf hydrangea be divided?
In USDA hardiness zones 5 to 9, oakleaf hydrangeas (Hydrangea quercifolia) are deciduous plants that survive the winter. They start to bloom in late spring and reach a mature height and width of 6 to 8 feet. Initially white, the blossoms progressively turn pink throughout the course of the summer until turning orange-red in the fall. Divide well-established shrubs while they are dormant in late winter or early spring in warm Mediterranean regions. The divisions could be distributed to friends and neighbors or planted elsewhere in the yard.
Before you divide the shrub, decide where you want to plant it so that you may immediately transplant the divisions. The shrub should be placed where it will get morning or evening sun with afternoon shade. Check the soil’s pH to make sure it is above 7 and alkaline.
With a dirt shovel, create a planting hole that is 2 feet in diameter and 1 feet deep for the hydrangea division. The soil from the hole should be broken up until it is loose and crumbly. If the pH is below 7, mix lime into the backfill soil to raise it.
Divide an 8- to 12-inch piece of stems and roots from the main bush using a sharp garden spade. To cleanly cut the roots, dig the spade into the root mass. Just outside the split clump’s root mass, insert a shovel into the ground. With the shovel, lift the split clump and set it on a sheet of plastic. To protect the soil and roots, pull the plastic sheeting up around the mass of roots. If the clump cannot be promptly replanted, pot it up in a container and keep it wet.
In the freshly prepared planting hole, place the clump with the plastic covering the root mass. Make sure it will rest at the same depth from which it grew previously. If additional soil is required to make the hole shallower, remove the clump from the hole and add it. At the bottom of the hole, tamp the soil down. Slide the plastic sheeting out from underneath the new hydrangea and insert it into the hole.
Around the roots of the hydrangea, uniformly press the backfill earth into the hole. When the bottom third of the hole is filled, gently tamp the earth down over the roots. Fill the hole up more. While backfilling, lightly tamp the ground. After the hole has been filled, water the new hydrangea to help the soil surrounding the roots stabilize.
At the edge of the transplant hole, create a 2- to 3-inch-high ring of earth around the new hydrangea. While keeping it 1 to 2 inches away from the stems, spread 3 inches of mulch over the earth around the hydrangea. For the first two years after planting, give it a weekly watering of once or twice.
When should hydrangea cuttings be taken?
When new stems initially begin to harden, in late spring or early summer is the ideal time to propagate softwoods. This occurs in the majority of locations between May and mid-July. At this point, cuttings are prone to strong growth and new hydrangea stems bend yet snap off readily.
Can oakleaf hydrangea cuttings be rooted?
I constantly receive praises on my oak leaf hydrangeas because they are so stunning. Is it possible to develop new plants from seeds or cuttings?
When in bloom, oak leaf hydrangeas are stunning and can be produced from cuttings. Take two to four cuttings, ideally from stems without flowers, from the tops of the stalks. Make that the stem has a node, which is the knobby line that runs through it and indicates the location of new growth. The cutting should be trimmed in half, dipped in a rooting hormone, and planted in a wet, sterile potting mix because the top half of the leaves are too big for the rootless plant to support.
Keep your cuttings out of direct sunlight by placing them in a plastic bag. Make sure the soil is still damp but not drenched by checking it. It may take these cuttings up to 12 weeks to root.
They can also be grown from any seed capsules that may still be on the parent plant, however starting from seed does not ensure that the new plant will look like the parent. You want the new plants to be identical replicas of your plant because it is getting excellent reviews.
Sandspurs are a nuisance in my yard. To kill them, I used atrazine, but it doesn’t seem to be working very well. Bahia is my lawn. What will sandspurs die from?
Atrazine belongs to the class of herbicides known as pre-emergents. These substances are quite effective at preventing seeds from sprouting into plants, but they are not very effective at killing existing plants.
A Bahia lawn can suffer significant harm from the herbicide atrazine. You’ll discover that benefin-containing products, such BASF Basagran, will be far more efficient against the bothersome sandspurs.
Make sure to read the label and follow the instructions when applying. Compared to replacing a herbicide-damaged grass, it is significantly simpler.
The TV ads for products that promise to keep flower beds weed-free intrigue me. Can they do that?
Trifluralin is present in the products you are referring to. Pre-emergent indicates that this herbicide stops seeds from growing.
You might be delighted utilizing this solution if your objective is to lessen the troubles caused by weeds that emerge as seeds. Additionally, it will stop plants like hollyhocks and impatiens from reseeding.
On weeds that spread via runners below the soil’s surface, such as dollarweed, oxalis, or rattlesnake weed, it won’t be as effective. You must apply a postemergent herbicide to certain weeds.
After applying Trifluralin, it needs to be soaked in pretty quickly. Observe the label’s instructions.
There is a spot in my yard where grass just won’t grow. I’ve checked the irrigation system, and it’s sunny. After three resoddings, I’m at a loss for what to do next. Any recommendations?
It will be wise to first determine the pH of your soil. The majority of us end up with a mixture of soils in our yards since backfill soil is used during building. If you bring a two-cup sample of your soil to the Extension Service at 1010 N. McDuff Ave., they can determine whether your soil has the ideal acid/alkaline balance for turf.
Dig a few places deeper as you are removing the sample. Homeowners may discover that the root growth is inhibited by abandoned concrete under the surface.
When the soil is removed and replaced with sterile soil, up to a depth of about 6 to 8 inches, I have had some success.
Can hydrangea cuttings be rooted in water?
Rooting hydrangeas is not too difficult. While some people have succeeded in rooting them in water, many others (like myself) have never been able to do so.
The image to the right, which Susan Park Cole forwarded to us, shows how hydrangeas can be rooted in water. On sometimes, roots appear when an arrangement is left in water for a prolonged period of time. But in my experience, this approach more frequently fails than succeeds.
