Essential Propagation Methods To Grow Everything (2024)

Once you know these five basic plant propagation methods, you can grow everything you want from seeds or existing plants. It’s a great way to clone your existing plants or grow more of what you love at a low cost.

Getting Started With Plant Propagation

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 fromseedorvegetative matter(using parts of existing plants).

Growing from seedis 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.

Besidesrooting 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 terminologyto 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.

5 Plant Propagation Methods

1Start from Seed

Seed startingis 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 Outsidehas 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,and open-pollinated. This explains more on the basic types of seeds.

You’ll also notice a lot of seed companies label everything “non-GMO.” This is because GMO (genetically-modified or genetically-engineered) seeds are not sold for home garden use. The one exception (as of Spring 2024) is The Purple Tomato sold by Norfolk Healthy Produce in the United States only.

Seeds go from dormant to germinatingwith changes in moisture, temperature, oxygen, and, in some cases, light. It’s different for each type, which is why it’s bestto 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.

2Division

Division is suited to herbaceous plants that grow inclumps.

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 befibrous,fleshy, orwoody.

Here’s some division examples:

• Fibrous Roots| Asters, Speedwells
• Suckers| Shrub Dogwoods, Lilacs
• Rhizomes |Bearded Iris, Elephant’s EarsAlocasia spp.
• Tubers| Caladiums (Caladium spp.), Dahlias, Shamrocks (Oxalis spp.)
• Offsets| Air Plants (Tillandsia spp.), Strawberries
• BulbsandCorms| Crocuses, Daffodils, Tulips
  Methods:Scoring,sectioning,scooping,coring |Amaryllis, Snowdrops, andscaling| 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 isafter flowering.
  • Spring and summer bloomersare divided infall.
  • Fall bloomersare divided inspring.

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

3Cuttings

When we propagate by vegetativecuttings(cloning), we remove a section of the plant and root it to grow on as a new plant. There aremanyplants that can be propagated this way and it’s much faster than growing from seed.

Cuttings areclonesof 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– SeeHow 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.

4Layering

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
• Stoolingormound 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 propagationwill illustrate all these methods with step-by-step instructions.

5Grafting

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 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.

Specialized Methods:

• Whipandtongue grafting
• Apical wedge, saddle grafting, side-wedge, approach grafting, four-flap, side-veneer, T-budding, chip budding
• Cactusgrafting

If you’re new to gardening,seed startingis 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 withcuttingsas 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.

Layeringtakes place right in the garden. It’s a set-it-and-forget-it method, requiring little effort.

Graftingcan get nerdy (in a good way), has neat possibilities for creating new fruit trees, and suits gardeners who misses science class.

Happy growing,
