Aptenia cordifolia

QUICK ANSWER
Stem cuttings root in 2 to 3 weeks and are the fastest way to fill new pots because almost any piece of stem will root.
Ground layering takes 4 to 6 weeks but produces ready-rooted plants without ever cutting the parent, ideal for a sprawling outdoor patch.

You'll need
Sterile shears or pinching fingers
A 4-inch pot with drainage holes
Cactus or succulent mix
A bright spot out of harsh midday sun
1
Cut 3 to 4 inch trailing tips
Choose healthy stems with plump green leaves and no flowers. Cut or pinch off pieces 3 to 4 inches long, just below a leaf node. The thick fleshy stems break easily, you do not even need shears for short pieces.
2
Strip the bottom leaves
Pull off the bottom inch of leaves on each cutting. Bare nodes are where new roots emerge. The leaves you remove can be tossed onto the soil surface, they sometimes root on their own.
3
Let the cuts callous for 1 day
Set the cuttings on a paper towel in a dry shaded spot for 24 hours. The cut ends will form a thin dry skin overnight. This species roots fast even without a long callous, but skipping it entirely raises the rot risk.
4
Plant in dry succulent mix
Fill the pot with cactus mix. Poke holes with a chopstick and push each cutting 1 inch deep, leaving the leafy top above the soil. Plant 5 to 6 cuttings per pot for a full look.
5
Water lightly and place in bright light
Mist the surface or water just enough to dampen the soil. Place in bright indirect light at warm room temperature, or filtered outdoor light if temperatures stay above 60 degrees Fahrenheit. Water again only when the soil is fully dry.
6
Resume normal care after rooting
Roots form within 2 to 3 weeks. New leaves at the tips confirm the cuttings have rooted. Move to direct sun and water deeply when the soil dries. The pot will fill in and start trailing within 2 months.
WATCH FOR
Cuttings turn yellow and mushy at soil level. That is rot from heavy soil or too much water. Pull the cuttings, trim off the rotted base half an inch above the damage, callous for 2 days this time, and replant in a sandier mix. Healthy cuttings stay firm and green from base to tip.

You'll need
A few small stones or U-shaped wire pins
A small trowel or spoon
Sterile shears (for the final cut)
A small pot of cactus mix (optional)
1
Find a long trailing stem touching soil
Look at the edges of an established plant for stems that already lie flat on the ground. Each leaf node along that stem is a potential rooting point, and many already have tiny white roots starting where they touch soil.
2
Pin the stem firmly to the soil
Place a small stone on top of the stem at a leaf node, or use a U-shaped wire pin pushed into the soil over the stem. The goal is firm contact between the node and damp soil. Pin 2 or 3 nodes per stem if you want multiple new plants.
3
Cover the pinned node lightly
Sprinkle a thin layer of cactus mix or garden soil over each pinned node, just enough to cover. Leave the leaves above the soil exposed. The buried node will root faster than an exposed one.
4
Water to settle and wait 4 weeks
Water the pinned area lightly. Aptenia roots in soil that is just barely damp. Check after 4 weeks by tugging gently on the leaves above the pin. Resistance means roots have anchored.
5
Sever and lift the new plant
Once a node has rooted, cut the connecting stem on the parent side with sterile shears. Wait another 2 weeks for the new plant to recover, then lift it with a trowel and pot it up or transplant it where you want it.
The parent plant fills the gap on its own within a month.
The parent plant fills the gap on its own within a month.
WATCH FOR
The pinned section dries out and shrivels before rooting. That is from soil that dried out completely or from a stem that lifted out from under the pin. Press the pin back down, water lightly, and shade for a week. As long as the stem is still green and flexible, it will recover.
