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 a hydrangea be split?
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.
Sanitize Your Pruners
By scrubbing the handle and blades of your pruners with rubbing alcohol after dipping a cotton ball in it, you can disinfect them. By taking this precaution, you can protect your new plant from fungal diseases.
Take Cuttings
Cut a green, healthy branch that has not yet developed flower buds on a mature hydrangea plant about 2 inches below a leaf node. Skip the older, woodier stems. Overall, the cutting should be 6 to 8 inches long.
Trim the Leaves
With your pruners, remove all except the top two to four leaves from the cutting, being careful not to harm the stem. Leave a space between the cut and the main stem while chopping the leaves. As a result, the main stem’s integrity is protected.
Dip Stem Into Rooting Powder
Put some rooting hormone powder on the cut end of the stem. Although adding rooting hormone is optional, most growers feel that success rates are increased by doing so.
Prepare a Pot
The quantity of hydrangea cuttings you are starting should be taken into consideration when selecting a pot. A few cuttings should fit in an 8–10 inch terra cotta pot.
A seed-starting potting mix should be added to your pot, and it should be fully moistened. Vermiculite or coarse sand are two more sterile growth mediums that can be used.
Plant the Cuttings
Insert each cutting all the way up to the base of the remaining leaves in the growing medium. Wrap the stems in the mixture, moistening it well.
The potted cuttings should be placed in a clear plastic bag that is just loosely fastened, and they should be placed in an area that receives bright indirect light but not direct sunshine, which might bake the cuttings and make them rot.
When the potting mix feels dry to the touch, add moisture by keeping an eye on it. The soil used for planting needs to be regularly moist but not saturated.
Repot as Needed
Your hydrangea cuttings will grow new roots in a month. You can carefully transplant individual cuttings into their own pots filled with regular potting soil once they do and new green growth starts so they can continue to develop into larger plants. Alternatively, now is the time to put fully established cuttings into the garden.
The young specimens can now start receiving weekly waterings and being treated like mature plants.
Transplant into the Garden
Follow recommended spacing recommendations when adding fresh hydrangeas to the garden by leaving a 4- to 6-foot space between each plant. The new hydrangeas will develop into flowering bushes the next growing season if they are planted in the fall.
Tip
Big leaf hydrangeas (Hydrangea macrophylla) can have their blossom color carefully controlled by altering the pH of the soil with the addition of various soil amendments. Pink blossoms typically grow on alkaline soils, while blue flowers typically grow on acidic soils.
When ought hydrangeas to be moved?
The majority of people are aware that “transplanting” refers to the act of digging a plant up and planting it in another spot.
The BEST TIME to transplant hydrangeas, according to experts, is when they are dormant, or after the majority of their leaves have dropped. Hydrangeas were transplanted when I lived in South Carolina in late November or early December, but if your ground isn’t frozen, January or February work just as well.
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.
