How To Divide An Overgrown Hydrangea

Hydrangeas may typically be divided successfully. They are often divided and spread out because of how quickly they will develop and how much area they will need.

It’s vital to remember that in order to divide hydrangeas, the plant must have at least two stems emerging from the ground. As hydrangeas mature, they have one main stem and numerous smaller (and occasionally larger) offshoots from the base. These can be divided easily.

Step 1

Fall is the ideal season to divide hydrangeas because the leaves have already dropped and the shrub is getting ready to hibernate. The alternate time period is the start of Spring, just before any new vegetation starts to emerge. So, the only two occasions when you should begin dividing your hydrangea are at these two points.

Step 3

Use rope or twine to tie the limbs together so that they may be readily split into portions. For two reasons, you want to do this. The stem should be exposed for two reasons: first, to make it simpler for you to carry your shrub and keep everything contained, and second, to give you much easier access when you’re ready to dig.

Step 4

Dig a circle around your bush, about 2 feet from the main stem, and remove the root ball. Make deep, precise cuts with your shovel, then, if possible, release the roots from the earth without ever severing them. Be careful when removing the root ball; given the size of your hydrangea, it may be very heavy and a two-man task. For this reason, after it’s well-established, you could need an axe or pick to get rid of it. If your hydrangea is a much-older plant, you’ll be able to tell, and you should bring heavier tools to unearth it.

Step 5

Split your root ball in half. You can tell how healthy your hydrangea is by looking at the depth and diameter of the roots, no matter how large they may be. The root ball should be divided into whichever many portions you require using a shovel and probably your pitchfork. To separate equal-sized root balls from the main root ball, insert the shovel’s blade into the center of the root ball and then apply even pressure. It is advised to divide the center into two equal sections and then further divide from there if you are making four or more. It’s preferable to divide most hydrangea bushes into two or four portions, although it’s not always necessary to do so.

Step 6

Plant your hydrangeas in their new locations once you’ve made significant divisions. In order to prevent them from burning, it is better to plant on a day when the sky is gloomy. So that the roots can spread out and immediately penetrate, partially fill the hole with water and soften the dirt around them. Once you’ve planted it, add topsoil, manure, or compost to properly give it the nutrients it needs to grow. The hole must be excavated to the same depth as the one you first dug for the root ball. Ensure that the soil line corresponds to the soil mark on the stem of your plant. Don’t bury it any further than that.

Step 7

The newly divided hydrangeas should have mulch applied around them before being thoroughly watered over the course of the following several hours, preferably using a slow drip method. Your hydrangea will probably droop after the first day or so, but towards the end of the week, it will start to bloom once more. A newly transplanted or divided hydrangea will need more water to get its roots deep into the earth and absorb all those nutrients, so be sure to water it frequently throughout the summer.

Once you’ve finished, all you need to do is keep an eye on your plants all summer long. This technique is highly effective, and you will have lovely hydrangeas that begin to bloom in just a few weeks.

Can a huge hydrangea be split?

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.

When can hydrangeas be divided?

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 do I deal with an overgrown hydrangea?

Myers believes excessive trimming can be harmful, even though deadheading your hydrangeas can be beneficial for fresh growth. The energy held in the roots of “Annabelle” cultivars will all be used to produce above-ground growth, which is frequently insufficient to support the blooms, according to the author. The older stems can help sustain the new growth while a late winter 15 to 18 inch cutback will promote new development from the roots up.

If chopped, will a hydrangea grow back?

If you have hydrangeas like panicle and smooth hydrangeas, which set bloom buds on current season wood, you can be more liberal about pruning. Winter or fall are the optimum times to prune them. Even if you trim canes to the ground when the bushes are dormant, they will grow back and flower in the spring. However, cutting stems all the way to the ground over time weakens them, so you might need to stake the plants to keep them standing. This severe trimming could eventually make the plant grow back weaker.

Are hydrangeas’ roots deep?

It’s simple to presume that a Hydrangea’s aggressive stem growth must be matched by an equally strong root system underground. However, the roots of hydrangeas are surprisingly shallow. They don’t develop a central taproot like shrubs and rhododendrons do. Instead, they develop in a slack, extending mass of fibers known as a “root ball.”

A hydrangea’s roots will spend the most of their time in the top six inches or so of soil. They do, however, have a tendency to expand widely in a horizontal direction. Many gardeners learned this the hard way when wayward Hydrangea stems started sprouting up far from the main body of the plant or invading their walkways.

As a general rule, you can assume that the roots of your hydrangeas extend at least a few inches past the dripline, which is the horizontal circumference of the leaves of the plant.

Can I move a big hydrangea?

A: I want to relocate a sizable hydrangea plant to a different area of my garden. What time of year is ideal for this?

A huge hydrangea plant can be moved, but it will be very heavy so plan to seek assistance. Make sure to remove the largest portion of the hydrangea root ball.

Hydrangea shrubs can be planted in spring or fall, but the majority of the publications I read advise waiting for cooler weather and moving the bushes in late fall or early spring, when the plants are dormant but the soil is still usable.

The plant’s mature, unpruned size should fit in the new planting location. Pick a location with soil that drains effectively. Rich organic matter in the soil will help it retain moisture. Keep in mind that soil that is damp can nonetheless be effectively drained. A spot where water pools or takes a long time to drain should be avoided after a strong downpour.

An excellent location will not be completely shaded in the afternoon. To blossom, hydrangeas require sunlight—not intense sunlight, but also not complete shadow. Each kind of hydrangea has a different tolerance for sun exposure.

After relocating, give the transplanted hydrangea one good soak in water. After relocating, avoid overwatering, but give the plant additional watering over the course of the following two summers as it gets acclimated.

A: I have two healthy fig trees (same cutting), but for the second year in a row, neither of them has produced any figs. Advice?

A fig tree is something I’ve never grown. I’ve looked at a few sources and can suggest the following. I am aware that the cuttings are from the same tree and of the same age, but I am unaware of the reader’s growth practices.

Starting with the potential causes of a fig tree not producing fruit:

It isn’t old enough: A fig tree usually starts bearing fruit between the ages of two and six. It makes sense that two trees that were grown from the same cutting will develop similarly and reach maturity around the same time.

An issue with gardening is having too much nitrogen. A plant with too much nitrogen will have healthy leaves but no fruit. The majority of the sources I looked at advised making only one sparing spring fertilizer application.

Fig trees don’t like to be too wet or too dry, which causes water stress. Make sure the soil has good drainage, and keep it evenly moist but not soggy or humid.

Does this resolve the issue? I’m not sure, but I think the first step would be to look at the circumstances that each plant is facing. Do you drink more or less water? Does one plant receive run-off fertilizer from an adjacent lawn if it is planted in the ground? Does the soil differ in any way? What has changed?

If you’ve grown figs and have any tips for this reader, send them to me and I’ll share them with them.

Even though it’s only September, you should get your amaryllis bulbs from the previous winter ready to bloom once more as there are only roughly 15 weeks before Christmas. If you followed my instructions, you would have cut the flower stems back after they bloomed and preserved the greens through the winter. You will then plant them this spring and let them to thrive throughout summer. The containers are filled with lush, deep green leaves.

Move the pots inside and stop watering them right away. The bulbs need to become dormant.

They should be kept in a dark, cool (not cold) place. Once the leaf has dried up and become shriveled, remove it. Before they begin to grow once more, the bulbs will rest for eight to twelve weeks.

Water the bulbs and relocate them to a location with bright but indirect light as soon as you see fresh growth. After emerging from dormancy, the bulbs should flower four to six weeks later. After 12 weeks, if they still don’t sprout, try watering them and moving them into light.

Until the first frost, I normally leave my amaryllis outside. Because of this, I had lovely flowers in February, when I really value them. For my Christmas display, I usually buy fresh bulbs, however after a while, I have a lot of bulbs. Can there ever be too many amaryllis flowers, though?

I have finally recovered from Lyme disease symptoms after taking medications and avoiding sunshine for more than two months. Every time you walk outside, take precautions against ticks to spare yourself a lot of pain. Although that is a story for another day, the garden is a jungle.

This orchard is nearby, accessible, and reasonable—only it’s 15 minutes from my house. James Hamilton founded it in 1974, and his twin sons Ron and Rick now oversee it. The family website states that the orchard started providing pick your own in 2015. On a Saturday afternoon, my friend Betty Cauler and I went and came home with a lot of gorgeous nectarines and peaches (Flaming Fury) (Fantasia).

There are now also apples accessible. Find a local producer and enjoy the delight of freshly picked, locally grown fruit if you are unable to do so yourself.
