If you want more of those vibrant, drought-tolerant blooms in your garden, learning how to propagate ice plants is the perfect skill. This easy step-by-step guide will show you several simple methods to get new plants for free.
Ice plants (Delosperma, Lampranthus, and others) are succulents known for their dazzling flowers and hardiness. They’re incredibly easy to multiply, making them ideal for filling in ground cover or sharing with friends. Whether you have an existing plant or know someone who does, you can create many new ones with just a little effort.
How to Propagate Ice Plants
There are three primary ways to propagate ice plants: stem cuttings, division, and from seed. Stem cuttings is the fastest and most reliable method, while division is great for mature, overgrown clumps. Growing from seed takes patience but can be rewarding if you want a specific variety.
You’ll have the best success if you propagate during the plant’s active growing season. For most climates, this is late spring through early fall. The warm temperatures and longer days help cuttings and new divisions establish roots quickly.
What You’ll Need to Get Started
Gathering your supplies before you begin makes the process smooth. You likely have many of these items already in your gardening toolkit.
- Sharp, clean scissors or pruning shears.
- A well-draining potting mix (cactus/succulent mix is ideal).
- Small pots or seedling trays with drainage holes.
- A small trowel or garden knife for division.
- Rooting hormone (optional but helpful for cuttings).
- A watering can with a gentle rose attachment.
- Gloves (the sap can sometimes be a mild irritant).
Method 1: Propagating from Stem Cuttings (The Easiest Way)
This is the method I recommend for beginners. Ice plant stems root readily, and you can see results in just a few weeks.
Step 1: Take Your Cuttings
Look for a healthy, non-flowering stem on your ice plant. Using your clean shears, cut a piece that’s 3 to 6 inches long. Make the cut just below a leaf node (the point where leaves emerge from the stem).
It’s best to take several cuttings at once, as not every single one may root successfully. Choose stems that look plump and green, avoiding any that are woody or shriveled.
Step 2: Prepare the Cuttings
Gently remove the leaves from the bottom one-third to one-half of the cutting. This bare section is where the new roots will form. If you’re using rooting hormone, now is the time to dip the cut end into the powder, tapping off any excess.
Let the cuttings sit in a dry, shaded spot for a day or two. This allows the cut end to form a callus, which prevents rot when you plant it. Don’t skip this step—it’s crucial for succulents.
Step 3: Plant the Cuttings
Fill your small pots with the well-draining potting mix. Moisten the mix lightly so it’s damp but not soggy. Poke a small hole in the center of each pot with your finger or a pencil.
Insert the callused end of the cutting into the hole. Gently firm the soil around it to provide support. You can place multiple cuttings in a larger tray, but space them a few inches apart so their roots don’t tangle immediately.
Step 4: Initial Care for Cuttings
Place the pots in a warm, bright location out of direct, harsh sunlight. A spot with bright, indirect light is perfect. Water very sparingly at first—only when the top inch of soil feels completely dry.
In about 2 to 4 weeks, you can test for roots by giving the cutting a very gentle tug. If you feel resistance, roots have formed! Once you see significant new growth on the stem, you’ll know it’s happily established.
Method 2: Propagating by Division
Division is the process of spliting an existing plant into two or more smaller plants. It’s best done in early spring or fall for ice plants.
Step 1: Water and Loosen the Plant
Water your ice plant thoroughly a day before you plan to divide it. This reduces stress and makes the roots more flexible. Carefully dig around the entire clump with a trowel, trying to lift the whole root ball out of the ground or pot.
Step 2: Separate the Clump
Shake off some excess soil so you can see the natural divisions in the plant. You’ll notice the clump is made of many individual stems and root systems. Gently pull these sections apart with your hands. For tougher clumps, you may need to use two garden forks back-to-back or a clean, sharp knife to cut through the center.
Ensure each new division has a good amount of roots and several healthy stems attached. Discard any old, dead, or damaged sections from the center of the clump.
Step 3: Replant the Divisions
Replant your new divisions promptly. You can put them back in the garden or into individual pots. Dig a hole wide enough for the roots, place the division in, and backfill with soil. Water them in well to settle the soil around the roots.
Keep the newly divided plants in a slightly shaded area for about a week to help them recover from the shock before moving them to full sun. They might look a bit wilted at first, but they should perk up quickly.
Method 3: Growing Ice Plants from Seed
This method takes the longest but allows you to grow unique hybrids or a large quantity of plants. Start seeds indoors 6-8 weeks before your last expected frost date.
Fill a shallow tray with a seed-starting mix. Scatter the tiny seeds lightly on the surface—do not cover them, as they need light to germinate. Just press them gently into the soil. Mist the surface thoroughly with a spray bottle.
Cover the tray with a clear plastic lid or plastic wrap to maintain humidity. Place it in a warm, bright location. Seeds typically germinate in 2-4 weeks. Once seedlings appear, remove the cover. When they have several true leaves, you can carefully transplant them into small pots.
Aftercare for Your New Ice Plants
Your propagated ice plants need a little special attention until they’re fully sturdy. The key is to avoid overwatering, which is the most common mistake.
- Light: Gradually acclimate them to full sun over a week or two. Mature ice plants thrive in full, direct sunlight.
- Watering: Water when the top inch of soil is dry. Established ice plants are very drought-tolerant and prefer to dry out between waterings.
- Soil: They demand excellent drainage. Use a gritty, sandy mix to prevent root rot, especially in containers.
- Feeding: Fertilize sparingly. A half-strength, balanced fertilizer applied once in early spring is often enough for the whole season.
Once your plants are growing well, usually after one full season, they require minimal care. They’ll begin to spread and will reward you with a carpet of colorful blooms. You can even take cuttings from these new plants to continue the cycle.
Troubleshooting Common Propagation Problems
Sometimes, things don’t go perfectly. Here’s how to fix common issues.
Cuttings are rotting or mushy: This is from too much moisture. The cutting likely wasn’t callused enough, or the soil was kept too wet. Ensure your potting mix is fast-draining and let cuttings callus fully. Water less frequently.
No root growth after several weeks: The cuttings may not be getting enough warmth or light. Move them to a warmer, brighter spot (but not direct, hot sun). Using a rooting hormone can also stimulate growth.
New divisions are wilting severely: They may have lost to many roots during division or are getting to much sun too soon. Trim back some of the top growth to reduce stress on the roots and provide temporary shade.
Leggy or stretched seedlings: This means they are not getting enough light. Move them to a much brighter location immediately. A grow light can be very helpful for seedlings started indoors.
FAQ: Your Ice Plant Propagation Questions Answered
How long do ice plant cuttings take to root?
In ideal conditions, ice plant cuttings can start to form roots in as little as two weeks. Most will be well-rooted and ready for more regular care within 3 to 5 weeks.
Can you put ice plant cuttings directly in soil?
Yes, you can place cuttings directly into soil, but it’s highly recommended to let the cut end dry and callus over first. This one simple step drastically improves your success rate by preventing rot.
What is the best time of year to propagate ice plants?
The best time is during their active growing season, from late spring to early fall. Warm temperatures and long daylight hours encourage rapid root growth. Avoid propagating in the dead of winter when plants are semi-dormant.
How often should I water newly propagated ice plants?
Water very carefully. Keep the soil barely moist for cuttings and divisions, not wet. Always check that the top layer of soil has dried out before watering again. Overwatering is the fastest way to lose new propagations.
Can ice plants be grown in containers?
Absolutely. Ice plants do very well in containers as long as the pot has excellent drainage. In fact, starting your propagations in pots gives you more control over soil and water, making it easier to manage their care when they are young.
Propagating ice plants is a simple and satisfying project. With these methods, you can quickly expand your garden’s color and texture. The plants you create will bring you joy for many seasons, and they make wonderful gifts for fellow gardeners. Remember, the most important ingredients are a well-draining soil and a little patience.
