A hydrangea’s roots shoot can be cut off from the mother plant and planted somewhere to produce a new (and free) hydrangea.
Q: In front of my house, there is a really enormous hydrangea. It receives morning sun and is flourishing. I want to split it in half and move a piece of it to another area of my yard. Can you divide hydrangeas? If so, when would be the ideal time to do it? Do they thrive in the shade?
A: Hydrangeas are an exception to the rule that not many shrubs may be divided like perennial flowers, and they are probably one of the simplest to “create kids” this way. Comparable to splitting a perennial flower, the procedure.
The greatest option is to search for shoots that are poking through the plant’s outermost layer. These shoots typically have their own healthy underground root system at their base a year or two after they first appear.
Sever the stalk with a spade to check for a piece with roots. If you succeed, you will have a young plant that is prepared for replanting.
This type of viable perimeter shoot is common on mature hydrangeas, and it can be dug up and divided. It’s the major method by which hydrangeas increase their range.
Whole hydrangea plants can be pulled up and divided into two or more parts if you don’t notice any shoots or are obtaining portions with no roots.
Look for naturally occurring divisions in the root ball, such as intersections where the main stems are protruding. A wishbone from a turkey can sometimes be separated by simply pulling apart the parts. To divide the plant, you could occasionally require a fork or a shovel.
In either case, you now have two plants to replant once you have two sections with roots connected to each.
Early spring is the ideal time to divide bigleaf hydrangeas, when the stems’ fresh green buds are just beginning to swell and unfold. A few while ago, that was. Mid to late October is an excellent period as well.
Treat divisions like a fresh plant by keeping them continually wet. These divisions’ smaller, weaker roots can’t draw as much moisture from the soil as a mature hydrangea’s large, well-established root system.
Your hydrangea’s placement in the early-morning sun is ideal. The majority of hydrangea varieties thrive in rich, moist soil with good drainage that receives early and afternoon shade.
Although they will live in heavy shade, they might not bloom at all or only slightly. Choose the native smooth hydrangeas, botanically known as Hydrangea arborescens, for heavy shade.
By the way, another question I’ve been getting lately is how hydrangeas will fair after many of their new leaves were destroyed by the almost record-breaking cold weather we experienced the third week of April.
Only the young leaves sustained the harm that I saw. In June, I predict that fresh leaves will emerge and the flower buds will unfold gracefully.
The flower buds weren’t developed enough, in my opinion, for the late cold blast to cause them significant harm.

Can you replace a portion of hydrangea that has been cut off?
Early in the day, before the heat and sun of the day begin, is when plants are most refreshed and hydrated. These shrubs require moisture to survive. Cuttings of hydrangea collected in the early morning have a significant advantage over cuttings from hot, dried-out stems.
Pick a fresh stem from the growth of the current year. Compared to older stems, it will have a lighter hue. Select a stem with many of leaves that is non-flowering for the greatest results. You can take several cuttings from different stems or use one stem for many.
Using a knife or pruning shears, cut the stem into 4- to 6-inch sections. Each piece should be cut just above the node where the stem and leaves meet. New roots will grow from these nodes. Every leaf but the one put at the top of each cutting should be removed. Then, keep the cuttings moist as you work by submerging them in shallow, warm water.
How soon may I divide my hydrangea?
Depending on how well established it is, a hydrangea will require different tools to split. More hardware is required the more developed it becomes!
Most Hydrangeas in pots may probably be divided by hand, with nothing more than a good pair of gardening gloves. We would advise including the following tools for one that is rooted in the ground:
To remove the roots out of the ground, more mature Hydrangeas may need a more powerful tool, like a pick or an axe.
The most important step in getting ready to divide your hydrangea, which isn’t even a tool, should be mentioned last:
the right moment. When they are dormant, in the spring or the fall, hydrangeas should be divided. Their root systems are more susceptible to damage in the summer since they are actively producing new growth.
How can hydrangeas be cut without the plants dying?
If you enjoy hydrangeas as much as I do, you may recall the post I wrote in the spring on how to make hydrangeas pink or blue. I had to figure out a way to prevent my cut hydrangeas from withering once I got this sorted out. Without the proper care, the blossoms might occasionally begin to wilt after being cut.
How to Cut Hydrangeas So They Will Not Wilt
I’ve had luck with pruning hydrangeas in a way that prevents them from wilting thereafter by using these gardening advice.
- Hydrangeas should be pruned in the morning.
- Hydrangea leaves occur in pairs, and you should trim the blossoms where two stems meet so they can continue to bloom.
- Cut hydrangea stems with leaves that are about 8 inches long. Later, you can trim to vase size.
- DO NOT cut the stems with clippers or scissors; instead, use a very sharp knife with a smooth blade (not a serrated blade).
- Don’t cut the stem horizontally. The stem becomes pinched when you cut it with scissors or across the grain, which prevents water from entering.
- Use the knife to make a 2- to 3-inch-long diagonal cut down the length of the stem. This makes it possible for a lot of water to enter and ascend the stem.
- As soon as the stems are chopped, submerge them in water.
This method of cutting the stems will result in large, luxuriant blossoms that won’t wilt.
Free Hydrangea Vase Idea: I used a sizable pickle jar that you get when you buy in bulk at stores like Costco because I didn’t have a vase big enough to contain the long-stemmed hydrangea blooms I cut from my yard. works flawlessly.
Emergency Method to Stop Hydrangeas from Wilting
You can attempt to revive hydrangea blooms that are beginning to wilt by completely immersing them in water for around 40 minutes. Recut the stems’ bottoms next, submerge them briefly in boiling water, and then put them back in a vase with fresh water. They should recover in a few hours and continue to be healthy for a few more days.
Hydrangea Tips that May Help You Get Bigger and More Blooms Every Year
Growing Hydrangeas: Contrary to popular belief, fertilizer actually supports the development of more leaves on hydrangea plants rather than more flowers. One application of a well-balanced slow-release fertilizer in the spring should be plenty if you decide to use fertilizer.
Cutting Hydrangeas: You shouldn’t prune your hydrangea very much if it blooms on old wood (i.e., stems from the previous year). If you wish to dead head the plants as soon as they blossom, you can trim the ends of the branches up to the first set of two leaves. However, if you remove any more than that, you risk eliminating part of the flowers that will blossom the next year. This goes for cutting flowers for your dining room table arrangement as well.
