How to propagate a snake plant
A snake plant multiplies in two ways, and one of them is almost impossible to get wrong. The other is slower, but gives you lots of plants from a single leaf.
The surest way to propagate a snake plant is to divide it: separate a piece of rhizome, with leaves and roots, and pot it up. The other is to cut a leaf into pieces and plant them in soil, bottom end down. It’s slower, and gold-edged snake plants tend to lose their edges.
How do you divide a snake plant?
A snake plant (Dracaena trifasciata) grows from a rhizome, a thick stem under the soil that keeps sending up new leaves. Dividing it simply means separating a part, with roots, and planting it on its own.
When. In spring, while the plant is growing. If you’re repotting anyway, take the chance.
How.
- The day before, let the soil dry out: it slips out of the pot more easily.
- Lift the plant out and shake the soil off the roots.
- Pick a piece of rhizome with leaves and roots and cut it with a clean knife or scissors. Some shoots pull apart by hand.
- Leave the cut to dry for a day or two so it seals.
- Pot each piece in a pot with a drainage hole, in cactus or succulent soil.
- Hold off watering for the first few days, then go back to the usual rhythm.
Each piece is a new plant, identical to the parent, including the yellow edges if it has them. The bigger the piece, the faster it settles in. Low rosette types such as ‘Hahnii’ send up offsets beside the main plant, which come away in the same manner.
How do you take leaf cuttings?
Any healthy leaf will do, and it gives you several plants at once. It’s slow: expect around two months before a shoot appears, and sometimes longer.
How.
- Cut a healthy leaf at the base with clean scissors.
- Cut it into pieces of about seven to ten centimetres. Mark the bottom end of each (for example, by cutting the top one at an angle): a cutting only roots with its bottom end down.
- Leave the cuts to dry for one to three days, until a dry skin forms.
- Bury the bottom end of each piece, two to five centimetres deep, in cactus or succulent soil, damp but not soggy.
- Set them somewhere warm with several hours of bright, indirect light a day, out of direct sun.
- Wait. When the roots are strong and a shoot appears, move it to a pot of its own.
In water. Some growers root them this way, but it tends to rot more readily than soil. If you go with water, submerge just the bottom end and change it when it clouds.
Can I propagate a gold-edged snake plant?
You can, with a caveat: only division keeps the golden edges. The yellow comes from a mix of tissues inside the leaf itself, and a leaf cutting usually gives you an all-green plant. If you want copies of the parent, divide.
Division or leaf cutting: which should you pick?
| Division | Leaf cutting | |
|---|---|---|
| Difficulty | Easy | Medium |
| Time | A ready plant straight away | Weeks or months |
| Plants per attempt | A few | Many |
| Keeps the yellow edges | Yes | Usually not |
| Best time | Spring | Spring and summer |
How do you water the new plants?
A fresh division or a cutting drinks next to nothing. Wait for soil that’s dry to the bottom and, if in doubt, hold off. The rhythm shifts with light; here is the same plant in July:
| Where it lives | In July | In January |
|---|---|---|
| South- or west-facing window | 11 days | 21 days |
| East-facing window | 12 days | 24 days |
| North-facing window | 19 days | 38 days |
| Hallway or corner with no window | 27 days | 54 days |
How to choose the day is in how often to water a snake plant.
What usually goes wrong?
- The cutting rots. Soil too wet, or a cut that never dried. Water less.
- No roots appear. Not enough warmth or light, or the cutting is upside down. Check the bottom end.
- The division goes soft. Too much water in the first days. Read why a snake plant goes soft or flops.
- Months pass with nothing. That’s normal with leaf cuttings. Give them time.
Summary: propagating a snake plant
| Step | Division | Leaf cutting |
|---|---|---|
| Material | A piece of rhizome with leaves and roots | A leaf cut into pieces |
| Dry the cut | One or two days | One to three days |
| Plant | Pot with cactus soil | Bottom end buried, right way up |
| Watering | Very little in the first days | Damp soil, never soggy |
Quick questions
How long does a snake plant cutting take to root? Weeks, and the first shoot can take about two months or more. Rushing doesn’t help; keep it warm and bright, and don’t drench it.
Can I root the leaf in water alone? Some people do, but it rots more easily than in cactus soil.
What do I do once I have new plants? Follow the guide to how to care for a snake plant and look at the snake plant page.
New plants need new sums
Small roots drink little, and the parent’s rhythm no longer fits. In Verdejar, you add the new plant, tell it the pot and the light, and the app works out a rhythm made to measure.
