Propagating plants is fun and rewarding! Once you get the hand of it, you’ll be able to expand your collection of indoor or outdoor varieties, for FREE! In this post, you’ll learn all about plant propagation, and find out how to get started.
There is a great way to increase your plant collection beyond a trip to the garden center: propagation! Propagating plants allows you to take your existing collection, and grow lots of new little babies.
Plants reproduce and multiply by propagation, so technically you could do it with any that you have in your collection. You are just enhancing what they do naturally.
I propagate a lot of my plants, both houseplants and garden varieties. Not only is it super fun, it saves a ton of money too!
I’ve created entire garden areas using starts that I grew myself, and I’ve expanded my houseplant collection a ton over the years – all for free!
Some plants are easier to propagate than others. In fact, there are ones that can only be done by the pros in labs with lots of expensive equipment. But there are plenty that you can grow at home yourself.
Here’s what you’ll learn in this detailed guide:
What Is Plant Propagation
Propagation is a big word, but the definition is simple (well… at least my definition is simple!).
You might even already have a basic understanding of what the word means. But what does it mean when it comes to gardening? Here’s my definition:
Propagation is the process of creating new plants from existing ones.
That’s how I define it, because I like to keep things super simple! But let’s dig a little deeper, shall we?
By propagating plants you already own, you have unlimited potential to expand your collection, and fill your home and gardens with as much green as you want.
Here are a few other benefits of learning how to reproduce plants:
- Free plants – Have a new garden area or containers you want to fill on a tight budget? You can do it for free by multiplying the plants you already have.
- Trade for new varieties – Get new varieties by swapping cuttings, seeds, or starts with neighbors and friends.
- Overwinter cuttings only – Keep your favorite tropicals and annuals by overwintering the cuttings or small divisions, rather than bringing the whole container into the house.
- Gift giving – Give indoor or garden plants away as presents (they make great housewarming gifts)! Your friends will love the thoughtful gift, and they’ll never know it was free for you.
Common Plant Propagation Methods
There are a few different methods for propagating plants. Heck, you’ve probably already got some experience without even knowing it!
Many species can be multiplied using more than one method, and it’s fun to experiment to see what works the best for each type you have. Here are a few of the most common methods to try…
Sexual Plant Propagation
The primary reproduction method for most plants is sexual – through the pollination of flowers! As long as they aren’t sterile, most will form seeds after the flowers have been pollinated.
By harvesting the seeds that are naturally produced, you can grow more plants without spending money at the garden center. This is a great choice for prolific annuals and vegetables. Start here if you want to learn how… Growing Seeds.
Asexual Propagation In Plants
Asexual propagation uses already growing parts to create a separate “cloned” baby. Plants have different parts, like stems, leaves, offshoots, or bulbs, that are easy to grow for a fresh, new start.
- Propagating cuttings – Taking precise cuttings from the leaves, stems, or stolons (aka offsets, or runners), you can get them to grow their own roots, and eventually mature into a full-sized specimen.
- Propagating by division – Some plants form bulbs, corms, tubers, rhizomes, or suckers (aka babies or pups). You can divide these up to multiply them.
- By layering – In some cases, you can root stems without severing them. This way the new start still receives nutrients while it forms roots.
Best Time To Propagate Plants
The best time to propagate plants is in the spring or summer. If it’s humid where you live, you’ll find it much easier to be successful.
Avoid the hottest days of summer, especially in dry climates (unless you plan to do it indoors). Also, don’t try to do it in the fall. That’s when most plants begin to go dormant, and it makes reproducing them much harder.
Easiest Plants To Propagate
While some plants are extremely easy to propagate, others are a bit more challenging. If you’re a beginner, then it’s best to start with something easy.
If you want to try it for the first time, or just want to experiment with new methods, then I recommend choosing something from the list below.
- Burrow’s tail
- African violet
- Jade plant
- Holiday cactus (Christmas or Thanksgiving)
- Spider Plant
- Wandering jew
Basic Plant Propagation Equipment & Supplies
Before you can propagate plants, you will need a few supplies. Don’t worry, you won’t need a bunch of expensive equipment to get started.
Heck, you probably already have some of this stuff at home. You can see a more detailed list here… Plant Propagation Supplies. But I’ll give you a quick list of the basic things you’ll need…
- Propagation soil – I make my own using a mix of perlite, vermiculite, and potting soil – but a nice seed starting mix will work too.
- A container – This can be a fancy propagation chamber, a pot with a clear plastic bag, or you could try to make your own DIY propagation box.
- Rooting hormone – To make it faster and easier to root slips and pieces, I highly recommend using rooting hormone. It’s inexpensive to buy, and totally worth it to increase your success rate.
- A cutting tool – For taking cuttings you’ll need to use a sharp, sterile pair of clippers, micro snips, bonsai shears, or a knife
- Bottom heat (optional) – Using a heat mat can help the cuttings root faster.
How To Propagate Plants Step By Step
Before getting started, make a list of plants that you’re interested in propagating. I recommend choosing from the list above if you’re a beginner.
Keep in mind that it takes much longer to get a mature specimen from leaves or seeds than it does from division or stem cuttings.
So if you want to have mature plants faster, then your best bets are to propagate them from either stem pieces, or by dividing them.
Propagating Plants By Division
Many plants make it easy for you to multiply them from the new growth (known as babies or pups) they regularly produce from their roots. All it takes to divide them is a delicate touch and some patience.
- Step 1: Carefully slide the entire rootball out of the pot.
- Step 2: Brush the soil away from the base of the pup that you want to remove to make sure it has roots of its own.
- Step 3: Gently tease them apart, slowly untangling the roots of the pup from those of the mother plant. Take care not to break any of the baby’s roots.
- Step 4: Use a sharp pair of clippers to sever the connection, and remove the pup from the mother.
- Step 5: Pot up the baby at the same depth it was growing in the original container.
Rooting Plant Cuttings
Rooting plant cuttings is where propagation becomes really comprehensive. There are a lot of varieties that you can grow from stems or leaves without having to wait for seeds and sprouting.
- Step 1: Dip the base of the stem or leaf in rooting hormone before sticking it into the medium.
- Step 2: Keep the rooting medium moist but not soggy, and never allow it to dry out completely.
- Step 3: Place the cuttings in a spot where they’ll be out of direct sunlight. An area near a sunny window inside the house is perfect. Outside, put them in the shade.
- Step 4: Cuttings will root faster in higher humidity. You can mist them regularly, or put a humidifier in the room to raise the moisture level.
- Step 5: Use bottom heat to facilitate the rooting process. In the winter, you can place your cuttings on a heat mat or near a vent (be careful, because the air from the heat vent will cause the soil to dry out faster).
- Step 6: New growth is usually the first sign that a cutting has rooted. Once that happens, gently brush the medium away from the base to check for roots.
- Step 7: Pot up the rooted slip into its own container. Place it at the same depth it was growing in the propagation tray.
Troubleshooting Common Propagation Problems
There’s nothing more frustrating than spending all the time to propagate plants, only to have problems. So in this section, I’ll list a few of the most common problems you may run into, and give you tips for how to fix them…
- Leaf drop – Cuttings will go into shock when you root them, so leaf drop is fairly common. But sometimes it can mean the piece died or rotted, so check the stem if leaves start to drop.
- Cuttings rotting – If your cuttings rot, that means they are getting too much moisture. Try allowing the soil to dry out more, and venting the plastic.
- Mold growth – When mold starts growing either on the soil or on the cutting, it’s another sign that there’s too much moisture. Vent the plastic, and let the soil dry out a bit between waterings.
- Bugs – If you find bugs on your leaf or stem slips, or see gnats flying around the propagation box, then it’s best to start over. They will only spread to other cuttings, or contaminate your sterile medium. Dump out everything, thoroughly clean the container, then start over with fresh, bug-free cuttings.
- Cuttings shriveling – It’s common for cuttings to droop for a day or two, but if they start to shrivel, it means they aren’t getting enough moisture. Increase the humidity around them.
In this section, I’ll answer some of the most frequently asked plant propagation questions. If you can’t find what you’re looking for here, then ask your question in the comments below.
Can you propagate any plant?
Yes, any type of plant can be propagated… but some are much, much more difficult than others.
What is a plant propagator?
A plant propagator is a box or chamber that is used to root cuttings. At minimum, it will have a tray and a plastic domed lid. Fancier propagators can come with heat mats, lights, and ventilation built into them.
How long do plant cuttings take to root?
It depends on the type of plant, and also the environment. The warmer and more humid it is, the faster the cuttings will root.
Do cuttings root in water?
Yes, many types of cuttings can root in water. It doesn’t work for all of them though. Also, cuttings rooted in water have a harder time becoming established in soil once they are potted up. So the survival rate can be much lower when rooting in water vs soil.
Whether you want to increase your own collection, or give the personalized gift of one of your babies, propagating plants can be fun and rewarding. Set yourself up for success by starting with one of the easy varieties above, and grow lots of new plants for free!
