The ZZ plant (Zamioculcas zamiifolia) is a true champion of low-maintenance houseplants. But what if you want to share its lush beauty with friends and family, or simply create more ZZ magic in your own home? The good news is ZZ plants can be propagated quite easily!
There are two main methods for propagating ZZ plants: stem cuttings and leaf cuttings. Both methods utilise the plant's underground storage organs called rhizomes, which store water and nutrients and play a key role in new growth. (a third method is if you have a big ZZ Plant. You unpot your plant and divide it into many plants depending on the size of the plant!)
Method 1: Propagating from Stem Cuttings
This method is generally considered faster and more reliable than propagating from leaves. Here's what you'll need:
- Sharp, sterilised pruning shears or knife
- Well-draining potting mix
- Pot with drainage holes (consider a clear pot for root monitoring)
- Optional: Rooting hormone
Steps:
- Identify a healthy ZZ plant stem.
- Using your sterilised shears, make a clean cut just below a joint (where a leaf meets the stem). Aim for a cutting with at least 2-3 nodes (the bump where a leaf or another stem might grow).
- Allow the cut end of the stem to callus over for a day or two. This helps prevent rot.
- Fill your pot with well-draining potting mix. You can create your own mix by combining perlite, pumice, and orchid bark for optimal drainage.
- (Optional) Dip the calloused end of the cutting in rooting hormone to encourage root development.
- Plant the cutting in the pot, ensuring at least one node is buried beneath the soil surface.
- Water the soil thoroughly until excess water drains from the pot's drainage holes.
- Place the pot in a location with bright, indirect light. Avoid direct sunlight. Or under a grow light.
- Keep the soil slightly moist but not soggy.
- Be patient! It can take several weeks or even months for roots to develop and new growth to appear (as ZZ Plants are slow growers).
Method 2: Propagating from Leaf Cuttings
While less successful than stem cuttings, propagating from leaves is still possible. Here's how:
- Sharp, sterilised pruning shears
- Well-draining potting mix
- Pot with drainage holes (consider a clear pot for root monitoring)
Steps:
- Carefully remove a healthy leaf from your ZZ plant, taking a small portion of the stem with it if possible.
- Plant the leaf base (where it connected to the stem) shallowly in a pot filled with well-draining potting mix.
- Water the soil lightly and maintain consistent moisture.
- Place the pot in a location with bright, indirect light or under a grow light.
- It can take a very long time (potentially a year or more) for roots and new growth to develop from a leaf cutting. Patience is key!
Remember:
- Regardless of the propagation method, using a well-draining potting mix is crucial to prevent root rot.
- Fertiliser is not necessary for newly propagated ZZ plants until they establish a good root system and show signs of new growth.
- Clear pots can be helpful for monitoring root development and ensuring proper moisture levels.
- Other propagation media can be used, such as perlite, sphagnum moss, or even a mix of both.
By following these steps and a little patience, you can successfully propagate your ZZ plant and share its vibrant foliage with the world. Happy propagating!
