Late summer and fall is the ideal time to take cuttings of many plants! Many of our favorite tender plants (such as coleus and geraniums) may not survive winter. It鈥檚 fun and quite satisfying to multiply your favorite plants鈥攆or free! Learn how.
One of my favorite aspects of gardening is plant propagation. Whether it鈥檚 from seed or from a cutting, I love seeing a new plant emerge and grow. Taking stem cuttings is an easy way to propagate your favorite garden plants in order to enjoy again next year, fill in empty garden space, or share them with friends.
Even with a greenhouse, we don鈥檛 have enough room for all the plants we want to save and it鈥檚 even more difficult if you are trying to fit them all on a sunny windowsill. Instead of lugging in large containers and digging up entire plants, you can easily take herbaceous, softwood, or semi-hardwood cuttings of your favorites and start new plants.
Almost any garden plant that produces stems can be be propagated via stem cuttings. Perennial flowers, vines, shrubs, and even trees are all great candidates!
Tender Plants
Around September, as temperatures cool, it鈥檚 time to take care of your tender container plants such as coleus and geraniums. They are at their peak in mid-summer, but when the weather turns colder, they will be lost unless you bring them inside. One way to ensure that they last through winter is to take a few cuttings and keep them indoors until spring.
Iresine is a great candidate for propagation.
You can truly take stem cuttings from any houseplant or herbaceous plant (those with non-woody stems) any time during the growing season (spring to late fall). Many root so easily that they will even root in a glass of water. (If you try this, keep the water clean and put the glass out of direct sunlight. Once roots form, transfer to soil.)
As well as coleus and geranium, tender plants include African violet, some ivies, iresine, mints, and impatiens.
Coleus are extremely easy to propagate, rooting readily from their stems.
Semi-hardwood Cuttings
With semi-hardwood plants (those with woody bases but soft growth at top), cuttings can also be taken in late summer to early fall. In autumn, hormone levels are high, so plants should root and grow well.
Semi-hardwood cuttings can be taken from woody evergeens include arborvitae, boxwood, holly, rhododendron, and yew, as well as other woody shrubs, like rose, lilac, hydrangea, and forsythia.
Many varieties of fuchsia, saliva, and penstemon won鈥檛 take severe weather so taking cuttings is a good precaution.
The new growth on this lilac shows the ripening wood at the base and soft wood at the top. Perfect for taking a semi-hardwood cutting from!

Hardwood Stem Cuttings
After a good frost, you can start taking hardwood cuttings. These cuttings are taken only when the plant is fully dormant (through early spring). Hardwood cuttings are taken from mature growth produced in the last season or the season before. These cuttings are slower to grow roots, but can still be grown successfully with a bit of patience!
Hardwood cuttings can be taken from most deciduous shrubs such as forsythia, rose, viburnum, deutzia, Rose of Sharon, and weigela.
Rosemary can be propagated via softwood cuttings (new growth), hardwood cuttings (old growth), or semi-hardwood cuttings (a mix of old and new growth).
Softwood Cuttings
Then back in the spring, plants begin to grow again. Softwood stem cuttings are taken in the spring and early summer鈥攂etween April and July鈥攆rom the tender new growth. These cuttings tend to grow new roots the fastest.
Before you start taking cuttings, take time to gather all the materials you鈥檒l need. If you are organized, you鈥檒l be able to prepare a lot of cuttings in a short time. You鈥檒l need:
clean plastic pots or boxes
a bag of sterile potting soil and perlite or vermiculite
powdered rooting hormone (optional, but recommended)
a sharp knife, clippers, or razor blade
rubbing alcohol to sterilize your cutting tool
As a rooting medium, you can use a mix of potting soil (soilless mixes are best) and perlite or vermiculite to make it drain faster. I have had success using straight vermiculite as well.
How to Take Cuttings: Guidelines
Taking cuttings is easy, but the methods used for propagating softwood, semi-hardwood, and hardwood cuttings differ slightly. The techniques are listed below, but first, here are a few general tips to keep in mind:
Cuttings taken from the base of a plant will typically root faster than those taken from the top.
Thin cuttings root better than thick ones.
Plants grown in shade root more quickly than those grown in full sun.
How to Take Herbaceous and Softwood Cuttings (Spring to Early Summer)
Herbaceous cuttings can be taken throughout the growing season (spring to late fall), while softwood cuttings should be taken in spring or early summer. Cuttings can be taken as long as the parent plant is healthy and in active growth. This method can be used on tender and hardy perennials such as verbena, mint, and petunias, as well as shrubs such as hydrangeas and fuchsia.
Fill your containers with a potting mix and water so that the mix is moistened.
Look for new, vigorous side shoots or tip growth and prune off a 3- to 4-inch piece just below a leaf node.
Remove the lower leaves and any flowers or buds, moisten the stem in water and dip it into a little pile of rooting hormone (not directly into the jar because you could contaminate the whole container).
Make a hole in the soil with a pencil, stick your cutting into the hole, firm the soil around it, and gently water it.
Take more cuttings. Twelve plants fit nicely in a rectangular box. Always take more cuttings than you need because some are likely to fail.
Be sure to include a label with any pertinent info on it!
How to Take Semi-Hardwood Cuttings (Mid-Summer to Early Fall)
Take semi-hardwood cuttings from mid-summer to early fall. A healthy semi-hardwood cutting includes a bit of both old and new growth. This technique works well on broadleaf evergreens such as holly, boxwood, and rhododendrons; deciduous shrubs such as lilac; woody herbs such as lavender, rosemary, and thyme; and even some conifers.
Fill your containers with a potting mix and water so that the mix is moistened.
Take a cutting that is 4 to 6 inches in length.
Remove the bottom-most leaves and the growing tip. If the remaining leaves are large, cut them in half horizontally to reduce the amount of moisture loss.
Dip the base of the cutting into a rooting hormone and stick it into a container of potting mix.
Place the container in a plastic bag and blow in some air to puff it up before tying it shut. Put the pot in a bright spot out of direct sunlight so you don鈥檛 cook the cuttings. Open the bag weekly to add fresh air and to check the plants for mold or new growth.
It can take 4-5 weeks or up to 6 months for roots to form, so don鈥檛 get discouraged. The firmer the wood, the longer it takes to root.
Another type of semi-hardwood cutting is called a 鈥渉eel cutting.鈥 Heel cuttings are pulled off the plant rather than cut (see photo, below). They will have a piece of old bark from the original stem still attached, which often aids in rooting.
How to Take Hardwood Cuttings (Late Fall to Winter)
Take hardwood cuttings in late fall or winter, when plants are dormant. These cuttings can also be taken in early spring before new growth appears. Generally, this method works great for deciduous shrubs such as forsythia, dogwood, viburnum, willow, mock orange, yew, and privet.
Fill your containers with a potting mix and water so that the mix is moistened.
Find a healthy-looking hardwood stem or branch that you can take a 6- to 8-inch cutting from.
Make the cut just below a bud (aka, a leaf node).
Trim off any softwood growth from the top of the cutting, making an angled cut right above a bud. Having an angled cut at the top of a cutting helps to prevent rot and also allows you to identify which end should be facing up!
Dip the base in rooting hormone. Stick the cutting in a container of potting soil, leaving only the top 2 to 4 inches exposed.
If you are making a lot of cuttings, stick them 4 to 6 inches apart in a nursery bed outside and cover with floating row cover.
If using pots, put them in a protected but unheated place (like a cold frame or shed) where they get some light.
Keep the soil on the dry side during the winter and start to water more as the temperatures warm up. Move the pot outside to a shady spot after the last frost of spring. You should see some new growth by mid-spring.
Where to Keep Cuttings
Many people use a sunny windowsill as their temporary nursery, but if you wish to create lots of pots with cuttings, here鈥檚 any easy way to create a mini-greenhouse 鈥
Place the box or pot of cuttings in a large plastic bag, blow in it to inflate it, and seal the end. Big zip-lock bags work great.
Place this in a warm spot out of direct sun: 65 to 75掳F is optimum. Bottom heat helps cuttings root faster, but is not necessary.
Open the bag every few days to check for mold or wilted cuttings and to add fresh air. This helps to prevent mildew from forming in this humid atmosphere.
After a week or two, if the plants look lively, you can peel back the bag and move them into indirect light. Check for rooting by giving them a gentle tug. If they resist being pulled out, roots have begun to form.
Soon you鈥檒l be able to move your new plants into their own pots filled with fresh potting soil. After a few weeks you can fertilize them and move them to their new indoor locations!
Cuttings in their new home. Hopefully they will root!
When spring comes around and the threat of frost has passed, plant your rooted cuttings outdoors as you would a young plant. Keep an eye on them for a few weeks, watching that they get enough water and don鈥檛 get burnt up by the sun or bitten by frost.

Coneflowers cannot be propagated through stem cuttings, unfortunately. However, they can be propagated through 鈥渞oot cuttings,鈥 which just involves taking part of a root clump from an existing coneflower plant. This is also called 鈥渄ivision鈥 and should be done every 3鈥5 years anyway, as it improves the health of plant and cuts down on overcrowding. These root cuttings can be planted directly in soil. Learn more about coneflowers.
I try and grow anything and I have a problem my green thumb is black I have a problem obviously don't know what to do I have read books I have done exactly what things have said and still my plants die I'm trying so hard to grow something just keep sending me instructions and hopefully I can grow something anything that would be easy to grow I would appreciate I have made Roots with water and then plant them instructions and hopefully I can grow something anything that would be easy to grow I would appreciate I have made roots with water and then plant them and they die I don't know what it is that I'm doing wrong. Please help
It might be your water? Indoor plants I use distilled water. Can buy it at grocery or major shopping stores. If adding fertilizer, use only a drop or two. Too much will burn/kill a plant. Hope this helps.
I personally believe that there is something in my skin that destroys plants. I can keep them alive as long as I don't actually touch them with my hands. Try using gloves. Its a simple inexpensive way to give it another shot. Good luck!
