5 Basic Types of Plant PropagationNEW! Click play to listen:
For those of us who start gardening as adults with little or no experience, it’s pretty common to buy established plants and perhaps start some veggies from seeds.
Once you fall in love with plants and want more of them, learning some basic plant propagation methods will serve you well. While you won’t have the instant gratification of buying plants, you will save heaps of money and—better still—discover the intriguing world of how plants grow.
We can grow new plants from seed or vegetative matter (using parts of existing plants).
Growing from seed is the most basic way, but not always the most efficient. Seed sowing is excellent for things like quick-growing veggies, but unrealistic for mortals with limited time on earth who want more of their favorite flowering dogwoods.
Besides rooting plant cuttings, there are numerous other propagation methods as well, depending on the plant and season.
Have a look at the basics (below) and get ready to grow your own garden. I’ve included lots of propagation terminology
to scare you off (kidding), to get you comfortable with it. You’ve probably heard many of them and now you can start trying them. Once you see how simple it is, you’ll wish you had started much sooner.
Plant Patents: Some plants are patented and asexual reproduction is not permitted without permission from the patent holder. Patents and trademarks are listed on plant tags.
These are some of my favorite books on plant propagation. They have photo tutorials for growing plants from a variety of methods. Once you know the basics, it’s super fun and addictive.
Grow Your Own Garden by Carol Klein was the first one I bought and still the one I refer to most.
1Start from Seed
Seed starting is the most popular propagation method for home gardeners, and a great choice for many plants like quick-growing veggies. I’ve been growing plants from seed for many years and it still seems magical every time.
My eBook, Seed Starting for Beginners: Sow Inside Grow Outside has everything you need to know to start a variety of plant seeds including annual and perennial flowers, vegetables, and herbs, if you would like a good beginner level guide.
As you get into this, you’ll notice these terms for the basic seed types and characteristics: heirloom, hybrid, open-pollinated, and genetically-modified.
Seeds go from dormant to germinating with changes in moisture, temperature, oxygen, and, in some cases, light. It’s different for each type, which is why it’s best to follow the instructions on your seed packets.
Here’s some more things that come up in seed starting, depending on which type of seeds you are sowing:
- Water – Moisture, humidity, pre-soaking (to soften the outer seed casing).
- Scarification – Scratching the seed coat to allow water to penetrate it.
- Stratification – Pre-chilling seeds before sowing.
- Light or dark – Some seeds need light to germinate, most do not.
- Temperature– In addition to moisture, seeds need certain temperature ranges to germinate.

Division is suited to herbaceous plants that grow in clumps.
Division is required when a plant is overtaking its space or exhausting resources. I divide plants to both maintain their heath and get new plants.
You may either dig up the entire plant and divide the root mass above ground, or dig into the soil, and remove individual clumps for transplanting.
Root systems can be fibrous, fleshy, or woody.
Here’s some division examples:
- Fibrous Roots | Asters, Speedwells
- Suckers | Shrub Dogwoods, Lilacs
- Rhizomes | Bearded Iris, Elephant’s Ears Alocasia spp.
- Tubers | Caladiums (Caladium spp.), Dahlias, Shamrocks (Oxalis spp.)
- Offsets | Air Plants (Tillandsia spp.), Strawberries
- Bulbs and Corms | Crocuses, Daffodils, Tulips
Methods: Scoring, sectioning, scooping, coring | Amaryllis, Snowdrops, and scaling | Lilies
While some plants are very forgiving, it is best to learn the basic anatomy of the plant’s roots before division, so you do minimal harm and get healthy divisions.
When to Divide Plants
This very basic guideline will serve you well. It also applies to pruning.
- The best time to divide plants is after flowering.
- Spring and summer bloomers are divided in fall.
- Fall bloomers are divided in spring.
I’m sure there are exceptions, but, overall, if you keep this in mind, you’ll have successful plant divisions without forsaking a season of blooms.
Here’s a few examples:
Divide in Spring
- Asters – divide fibrous roots
- Blanket Flower (Gaillardia x grandflora)- – divide fibrous roots
- Bleeding Hearts (Dicentra spp.) – divide crowns
- Lilacs (Syringa spp.) – divide suckers
- Sea Thrifts (Armeria spp.)- – divide fibrous roots
- Shrub Dogwoods (Cornus spp.) – divide suckers
- Speedwells (Veronica spp.)- – divide fibrous roots
Divide in Spring or Fall
- Bee Balm (Monarda) – – divide fibrous roots
- Bellflowers (Campanula spp.) – – divide fibrous roots
- Black-eyed Susans (Rudbeckia spp.) – – divide fibrous roots
- Goatsbeards (Aruncus spp.) – divide crowns
- Purple Coneflowers (Echinacea spp.) – – divide fibrous roots
- Yarrow (Achillea spp.) – divide fibrous roots
3CuttingsNEW! Click play to listen:
When we propagate by vegetative cuttings (cloning), we remove a section of the plant and root it to grow on as a new plant. There are many plants that can be propagated this way and it’s much faster than growing from seed.
Cuttings are clones of the parent plants with identical genetic code, whereas seeds may not be. If you want to grow the same lilac your mom has, take cuttings to propagate more.
This video shows hardwood cuttings in fall. The method is almost identical for taking softwood cuttings in spring and summer.

Types of Plant Cuttings and Examples
- Stem cuttings
- Greenwood – early to midsummer
- Softwood – early summer to midsummer | Step-by-Step Instructions
- Semiripe – late spring to midsummer
- Hardwood – late autumn or early winter, after the plant is dormant
- Conifer (Cedars, Spruces, Pines, Hemlocks) – late autumn or early winter – taken from side shoot in lower part of tree
- Cane – for tropical plants – Dracena, Chinese Evergreens
- Leaf petiole – See How to Grow African Violets from Leaf Cuttings
Holiday Cactus Care and Blooming Tips | Includes tips on propagating leaf cuttings
- Leaf vein – spring or summer – You’ve probably seen this done with Begonias
- Upright leaf cuttings – spring and summer– Begonias, Jade Plant (Crassula arentea)
- Monocot leaf cuttings – spring and summer – Snake Plant (Sansevieria trifasciata)
- Root cuttings – late autumn, early winter – Bleeding Hearts (Dicentra spp.), Oriental Poppies (Papaver spp.)
Greenhouses use mist systems (to maintain humidity), automatic watering systems, and bottom heat, to speed up root growth. While not as accurate or prolific, we can mimic these conditions with supplies at home.
Have you ever seen a raspberry plant with the canes bent over, touching the ground? Sometimes this triggers root growth at the point of contact. That’s layering, and it’s a method we can employ intentionally with cultivated, woody plants.
Layering takes time: it can be a year or more for the roots to adequately form. Eventually, we severe the new plant from the parent, leaving it in place until it has recovered and is ready for transplanting.
Here’s some layering methods and plant examples:
- Tip layering – mid to late summer – Forsythias, Blackberries, Raspberries
- Simple, Serpentine layering, – Spring – Serviceberries, Hollies, Magnolias
- Air layering – spring – Bougainvilleas, Camellias, Hibiscuses
- Stooling or mound layering – mid spring – Hazels, quince, blackberries, raspberries
- French – early autumn and spring (both) – Smoke Tree, Walnuts, Pears, Viburnum
- Dropping – mid summer or mid autumn- Cranberry, Scotch Heather, Blueberries
Again, a good book on plant propagation will illustrate all these methods with step-by-step instructions.
Ever see a grafted fruit tree? Grafted trees are created by taking a stem or bud (scion) from one or more trees and fusing them to a related rootstock. You can read more about getting started with grafting here.
I have a grafted apple tree where the base is one tree type, and the upper branches originate from different apple trees. This means the different cultivars can pollinate each other in spring and I get a variety of apples in the fall—all from one plant.
If this method interests you, I would suggest getting a good reference book or find a site or group of enthusiasts to explore this with.
Possibilities include apples, pears, roses, peaches, plums, apricots. almonds, cherry, grape, and more.
- Whip and tongue grafting
- Apical wedge, saddle grafting, side-wedge, approach grafting, four-flap, side-veneer, T-budding, chip budding
- Cactus grafting
If you’re new to gardening, seed starting is a natural place to start. I’d definitely go for that, growing things you want to eat or favourite ornamental plants, particularly ones that are hard to find at plant nurseries.
I’d also encourage jumping into propagation with cuttings as soon as you can. Even if you don’t have your own plants to take cuttings from, a friend may have some available.
Once you see how it’s done, it’s incredibly simple, takes just a few minutes, and eventually yields lots of free, new plants.
Layering takes place right in the garden. It’s a set-it-and-forget-it method, requiring little effort.
Grafting can get nerdy (in a good way), has neat possibilities for creating new fruit trees, and suits gardeners who misses science class.
