How to Divide ZZ Plants
1. Remove ZZ Plant from its Pot
It’s pretty straightforward to divide ZZ plants. First, remove the ZZ plant from its pot. It’s easier to do this if you have a small ZZ plant. It’s hard to remove large ZZ plants from their pot. In my case, my ZZ plant is bursting so it was really hard to pull it out of the pot. It was almost impossible to remove the overcrowded ZZ plant. The only way I could remove the plant from its pot was to cut the pot with a scissor.
2. Divide the ZZ Plant
After removing the ZZ plant from its pot, I visually inspected my ZZ plant for natural division points. Each division should have sufficient leaves, stems, tubers, and roots. I wanted to get 3 plants out of this one plant. I started pulling apart the ZZ plant.
Don’t be scared, it will feel like you are ripping your plant apart but as long as you give each division enough leaves, stems, tubers and roots it will survive. This is the most difficult part of the entire process. Sometimes, you may have to cut the tubers in half if that’s the only way to divide it.
3. Plant Each ZZ Plant Division
I managed to separate my ZZ plant into three plants. As you can see, each division has enough leaves, stems, tubers, and roots. I planted each division into its own pot. Make sure you don’t plant your ZZ plant too deep. You should be able to see the tubers, don’t cover the tubers entirely with soil. I used a well-draining, organic potting mix for my ZZ plant. And make sure your plant them in pots with drainage holes.
4. Water your ZZ Plant
After planting each ZZ plant, water each plant. Then keep them in an area with bright, indirect light.
ZZ Plant is Toxic to Humans and Pets
One thing you should know before dividing your ZZ plant is that it is toxic to humans and pets. ZZ plants contain calcium oxalate. Chewing on the leaves and stems can cause vomiting and difficulty breathing. It can also result in swelling of lips, tongue, and mouth and excessive drooling. I suggest being safe when you are handling your ZZ plant. Wear gloves. Don’t touch your eyes and mouth. Wash your hands thoroughly after handling your ZZ plant.
Here are my ZZ plants 1 week later. They look happy and healthy.
