💧 Water: Allow the soil to dry out completely between waterings. ZZ plants are drought-tolerant and prefer to stay on the dry side - overwatering can lead to root rot.
🌱 Soil: Use a well-draining potting mix - I personally use this potting mix. A mix with sand or perlite, like this one, ensures the soil doesn’t hold excess water.
☀️ Light: Bright, indirect light is ideal, but ZZ plants are incredibly adaptable and can thrive in low light. Avoid direct sunlight, which can scorch their leaves.
🌡️ Temperature: Keep your ZZ plant in a room between 60-75°F (15-24°C). They handle most indoor conditions well but don’t like extreme cold.
🌿 Fertilizer: Feed with a diluted, balanced fertilizer (my top pick is this Miracle-Gro one) every 2-3 months during spring and summer. Skip feeding in fall and winter.
Preparing for Propagation
Propagating ZZ plants is a straightforward process that can expand your collection or share plants with friends. Proper preparation ensures success and healthy new plants.
Let’s explore the key steps to get ready for ZZ plant propagation.
When to Propagate ZZ Plants
Spring and summer are ideal for ZZ plant propagation. These seasons provide warm temperatures and longer daylight hours, promoting faster root development and growth. Avoid propagating in late fall or winter when the plant is semi-dormant.
Choose a day when you have ample time to complete the process without rushing. Early morning is best, as the plant is well-hydrated from overnight moisture retention. This timing reduces stress on both the parent plant and cuttings.
Tools and Materials Needed
Gather these items before starting:
- Clean, sharp pruning shears or a knife
- Small pots with drainage holes
- Well-draining potting mix
- Rooting hormone (I always prefer to use this one)
- Gloves
- Spray bottle filled with water
Sterilize your cutting tools with rubbing alcohol to prevent disease spread. Choose pots slightly larger than the root ball or stem cuttings you’ll be planting. A mix of perlite, peat moss, and regular potting soil works well for ZZ plants.
Selecting a Healthy Parent Plant
Pick a mature, disease-free ZZ plant for propagation. Look for:
- Thick, sturdy stems
- Dark green, glossy leaves
- No signs of pests or diseases
- At least 12 inches tall with multiple stems
Avoid plants with yellowing leaves, soft spots on stems, or visible pests. A healthy parent plant increases the chances of successful propagation and vigorous new growth.
Water the parent plant thoroughly a day before taking cuttings. This ensures it’s well-hydrated, making stem removal easier and reducing stress on the plant.
How to Propagate ZZ Plants
ZZ plants can be propagated through several methods, each with its own advantages. These resilient plants are relatively easy to multiply, allowing you to expand your collection or share with friends. The following techniques will help you successfully propagate your ZZ plant.
Leaf Cuttings Technique
To propagate ZZ plants using leaf cuttings, start by selecting healthy leaves from the parent plant. Cut the leaves at the base where they meet the stem.

The best soil for ZZ Plants, made to support their low-maintenance nature. Well-draining and nutrient-rich, it helps prevent soggy roots while keeping your ZZ plant strong and healthy
Water sparingly and place the pot in a warm, bright location away from direct sunlight. Be patient, as this method can take several months for new growth to appear.
Keep the soil slightly moist but not waterlogged. Eventually, small bulbs will form at the base of the leaves, developing into new plants.
Division Method
The division method is ideal for mature ZZ plants with multiple stems. Begin by carefully removing the plant from its pot.
Gently separate the rhizomes and roots, ensuring each division has at least one stem and some healthy roots attached.
Prepare new pots with fresh, well-draining potting mix. Plant each division at the same depth it was growing before.
Water thoroughly and place the pots in a bright, indirect light location. Avoid fertilizing for the first month to allow the plants to establish themselves.
This method produces instant new plants – a great benefit of having a ZZ plant in your home – and is less time-consuming than other propagation techniques.
Stem Cuttings in Water
To propagate ZZ plants in water, select healthy stems and cut them into 4-6 inch sections. Remove the lower leaves, leaving only the top few. Place the cuttings in a clear glass or jar filled with clean water.
Position the container in a bright spot with indirect light. Change the water weekly to prevent bacterial growth.
After a few weeks, you’ll notice roots developing from the nodes. Once the roots are about an inch long, transfer the cuttings to pots with well-draining soil.
Water propagation is a fun way to observe root development, but it may take longer for the plants to adjust when moved to soil.
Stem Cuttings in Soil
For soil propagation, prepare stem cuttings as you would for water propagation. Dip the cut ends in rooting hormone to encourage faster root development.
Plant the cuttings in small pots filled with a mix of peat moss and perlite.
Keep the soil lightly moist and place the pots in a warm area with bright, indirect light. You can create a mini greenhouse effect by covering the pots with clear plastic bags, but remember to remove them occasionally for air circulation.
This method often results in stronger plants compared to water propagation, as the roots develop directly in their final growing medium.
Executing the Propagation
Propagating ZZ plants is a straightforward process that can be done through stem cuttings or leaf cuttings. Either method allows you to easily create new plants from existing ones, expanding your collection or sharing with friends.
Taking Cuttings
To start propagating your ZZ plant, choose a healthy stem or leaf. For stem cuttings, use clean, sharp scissors to cut a 4-6 inch section from the top of the plant.
Remove the lower leaves, leaving 2-3 at the top. For leaf cuttings, gently twist a leaf from the stem, making sure to include the petiole (leaf stalk).
Place the cuttings on a paper towel and let them dry for a day. This helps prevent rot when you plant them.
While waiting, prepare small pots with well-draining potting mix. Make sure the pots have drainage holes to avoid waterlogging.
Rooting Process
Insert the cuttings about 1-2 inches deep into the prepared potting mix. For leaf cuttings, place the cut end of the petiole into the soil.
Water the soil lightly, keeping it just barely moist. Too much water can cause the cuttings to rot.
Place the pots in a warm spot with bright, indirect light. Avoid direct sunlight as it can damage the cuttings.
You can create a mini greenhouse effect by covering the pots with clear plastic bags, but make sure to remove them daily for air circulation.
Be patient – ZZ plant cuttings can take several weeks to months to develop roots. You’ll know roots have formed when you see new growth emerging from the soil.
Once established, care for your new ZZ plants as you would mature ones.
Post-Propagation Care
Caring for your ZZ plant after propagation is crucial for your new plants to thrive. Focus on providing the right amount of water, light, and nutrients while allowing them time to adjust to their new environment.
It’s key to pay attention to their specific needs during this critical growth phase.
Watering Your New ZZ Plants
Water your newly propagated ZZ plants sparingly. Allow the soil to dry out completely between waterings.
For stem cuttings, wait until roots have formed before watering. Rhizome divisions can be watered lightly once planted.
Check soil moisture by inserting your finger about an inch deep. If it feels dry, it’s time to water. Use room temperature water and avoid getting the leaves wet to prevent rot.
During winter, reduce watering frequency as ZZ plants enter a dormant phase. Overwatering is the most common issue with these plants, so err on the side of underwatering.
Providing Proper Light
ZZ plants thrive in indirect light but can tolerate low light conditions. Place your newly propagated plants in a spot with bright, filtered sunlight. Avoid direct sun, which can scorch the leaves.
A north or east-facing window is ideal. If you’re using artificial light, keep the plants about 6-12 inches away from fluorescent bulbs for 12-14 hours daily.
Monitor leaf color – if they start turning yellow, move the plant to a brighter spot. Dark green leaves indicate the plant is getting enough light.
When to Fertilize
Hold off on fertilizing your newly propagated ZZ plants for the first few months. This allows them to focus on root development without the stress of rapid growth.
Once established, feed your ZZ plants every 2-3 months during the growing season (spring and summer). Use a balanced, water-soluble fertilizer diluted to half strength.

Apply fertilizer to damp soil to prevent root burn. Stop fertilizing in fall and winter when growth slows down.
Over-fertilizing can lead to salt buildup and root damage, so it’s better to under-fertilize than overdo it.
Potting and Soil Requirements
Choose a well-draining potting mix for your new ZZ plants. A blend of regular potting soil, perlite, and coarse sand works well. This mix allows excess water to drain quickly, preventing root rot.
Select pots with drainage holes that are 1-2 inches larger than the root ball. Terracotta pots are a good choice as they allow soil to dry out between waterings.
Repot your ZZ plants every 2-3 years or when they outgrow their current container. Spring is the best time for repotting. Be gentle when handling the roots to avoid damage.
Acclimating Young ZZ Plants
Gradually introduce your new ZZ plants to their permanent environment. If they’ve been in a high-humidity propagation setup, slowly reduce humidity over a week or two.
Keep them away from drafts, air conditioning vents, and heating sources. ZZ plants prefer stable temperatures between 60-75°F (15-24°C).
Be patient – it can take several weeks for new growth to appear. During this time, maintain consistent care and avoid moving the plants around too much.
Once you see new leaves emerging, you’ll know your propagation efforts have been successful.
Troubleshooting Propagation Issues
ZZ plant propagation can sometimes hit a few snags. Common problems include rot, fungal infections, pests, and slow root growth. Let’s explore solutions to these issues.
Dealing with Rot
Rot is a frequent problem when propagating ZZ plants. It often starts at the stem’s base or in the roots.
To prevent rot, make sure you’re using well-draining soil and pots with drainage holes. Water sparingly – ZZ plants prefer to dry out between waterings.
If you spot rot, act fast. Cut away any mushy or discolored parts with clean, sharp scissors.
Some people like to dust the cut areas with cinnamon, as it acts as a natural fungicide. Either way, let the cutting dry for a day before replanting in fresh, dry soil.
Consider using rooting hormone to boost your chances of success. It helps stimulate root growth and can make cuttings more resilient to rot.
Fungal Infections and Pests
Fungal infections can appear as white, fuzzy growth on leaves or soil. To tackle this, improve air circulation around your plants and reduce humidity. You can use a small fan to keep air moving.
For mild cases, try spraying the plant with a mixture of water and baking soda. More severe infections might need a commercial fungicide.
Pests like spider mites or mealybugs can also cause problems. Inspect your cuttings regularly. If you spot pests, isolate the affected plant immediately.
How to Get Rid of Pests on Your Houseplants
If you notice pests on your indoor plants, follow these steps to tackle the problem before it gets worse:
- Start with manual removal – For minor infestations, wipe leaves with a cotton swab dipped in rubbing alcohol or rinse the plant under lukewarm water to remove pests by hand.
- Use neem oil or insecticidal soap – If pests persist, treat your plant with neem oil or insecticidal soap (those are my preferred ones!), both of which target common houseplant pests without harming your plant.
- Apply a houseplant-safe pesticide – For severe cases that don’t respond to other treatments, use a broad-spectrum pesticide designed for indoor plants to eliminate stubborn pests – I use this pesticide for tough infestations.
By acting quickly and using the right treatments, you can keep your houseplants pest-free and thriving!
Slow or No Root Development
Sometimes, ZZ plant cuttings take their time growing roots. This is normal – patience is key. Make sure your cuttings are getting enough indirect light. Too little light can slow growth.
Check the temperature too. ZZ plants like it warm, ideally between 65-75°F (18-24°C). If it’s too cold, root development will stall.
Try bottom heat to speed things up. A heating mat designed for seedlings can work wonders. Just place it under your propagation tray.
If you’re water propagating, change the water weekly to keep it fresh. Add a drop of liquid fertilizer to give your cuttings a nutrient boost.
