ZZ Plant Propagation Methods

There are several methods you can employ to propagate ZZ plants, each yielding new babies for you to enjoy. Whether you have individual leaves, stem cuttings, or a mature plant ready for division, you can successfully multiply your ZZ plant collection.

From Cuttings

You can take stem cuttings of Zamioculcas zamiifolia or use individual leaves, rooting them in either soil or water. While they may be slow to grow, they require minimal maintenance. If you are aiming for larger plants in a shorter period, opt for stem cuttings. However, both methods work with a little patience.

By Division

Mature ZZ plants that have outgrown their pots can be conveniently propagated by division. Whether you choose to separate large chunks of the rootball or tease apart the individual rhizome segments, division is an effective way to multiply your ZZ plant collection.

When to Propagate Zamioculcas zamiifolia

The best time to propagate ZZ plant stem cuttings or leaves is during early spring or summer. By taking advantage of the warmer weather, your cuttings and plants will have optimal conditions for growth and success.

Supplies for Propagating ZZ Plants

Before diving into the propagation process, it is essential to gather the necessary tools and supplies to ensure a smooth and successful experience. Here is a list of what you will need:

  • ZZ plant cuttings or leaves
  • Rooting medium or water
  • Pot or vase
  • Rooting hormone
  • Clean, sharp clippers
  • Potting soil
  • Heat mat (optional)

Propagating ZZ Plant from Stem Cuttings

If you are ready to embark on the journey of propagating ZZ plants from stem cuttings, follow these tips for a successful propagation process. Remember to choose healthy stems with vibrant green leaves.

How to Take ZZ Plant Stem Cuttings

Taking a good-sized stem cutting from a Zamioculcas zamiifolia is a simple process. The cutting should be at least 2 inches in length, though it is recommended to aim for 3-4 inches if possible. Use clean and sharp clippers to ensure a straight and clean cut that avoids damaging the stems.

Preparing the Stem Cuttings for Propagation

To promote successful rooting, it is crucial to avoid shriveled or dried-out cuttings. Trim or pinch off the leaves on the lower 2 inches of each cutting to provide ample stem to be placed in soil or water.

Propagating Zamioculcas zamiifolia from Leaves

If you prefer to root ZZ plant leaves, follow these tips for proper removal and preparation. Keep in mind that this method is slower than stem cuttings, so it is recommended to root several leaves together.

How to Take ZZ Plant Leaf Cuttings

Using clean and sharp pruners, carefully remove the leaves from the plant, ensuring that a small nub of stem remains attached to the base of each leaf. Avoid tearing or breaking the leaves, as this may hinder successful rooting.

Preparing the Leaves for Propagation

Before rooting, ensure that the leaves do not shrivel or dry out. Place them into the rooting medium as soon as possible to maintain their vitality.

How to Root ZZ Plant Cuttings (Stem & Leaf)

Both ZZ plant stems and leaves can be propagated in either soil or water. Below, you will find step-by-step instructions for each method.

Steps for Rooting ZZ Plant Cuttings in Soil

Rooting ZZ plant cuttings in a soil medium encourages strong root development and has a high chance of success, albeit a slower process. Here are the step-by-step instructions for rooting stem cuttings or individual leaves in soil.

Step 1: Prepare your pots and medium – Use a well-draining rooting medium, such as a combination of equal parts potting soil and perlite or pumice. Fill the container almost to the top.

Step 2: Use rooting hormone – Dust rooting hormone on the cut ends of both the leaves and stems to stimulate faster growth.

Step 3: Create a hole with your finger – Make a space in the soil to avoid wiping off the hormone when inserting the cuttings. Bury stem cuttings approximately 1 inch down, and for leaves, bury only the bottom ¼ inch. Gently pack the medium around the cuttings, ensuring good contact with the base.

Step 4: Moisten the rooting medium – Add enough water to moisten the soil without making it soggy. Allow any excess water to drain from the pot.

Step 5: Place on a heat mat – ZZ plants root best within the temperature range of 75°F to 80°F. A heat mat placed under the pot can significantly expedite the rooting process.

Step 6: Choose a bright location – Provide your cuttings with plenty of indirect bright light, ensuring they are shielded from direct sunlight.

Step 7: Keep the soil on the dry side – While your cuttings are rooting, avoid letting the medium dry out completely. Maintain a slightly dry soil, avoiding overwatering.

Steps for Rooting ZZ Plant Stems or Leaves in Water

Water propagation can be an enjoyable method for observing the growth of roots and new rhizomes. However, be aware that it may result in less hardy plants. Rooting multiple cuttings in the same container will increase your chances of success.

Step 1: Grab a container – Select a glass or vase that can support the cuttings upright. Shot glasses or tea cups work perfectly for leaves. Opt for a clear container if you wish to observe root development.

Step 2: Add water – Submerge only the very ends of the cuttings in the water, as the roots emerge from the base. For leaves, ensure that the stem nub and bottom edge are submerged.

Step 3: Place in bright, indirect light – Protect the cuttings from direct sunlight. Ideal conditions include bright, filtered sunlight, or the use of a grow light if sufficient natural light is not available.

Step 4: Keep the water clean – If you notice cloudiness or debris in the water, rinse the container and refill it with fresh water. Cloudy or foul-smelling water indicates rot, so check the stems and discard any that appear mushy.

How to Propagate ZZ Plant by Division

Dividing ZZ plants is an effective way to quickly establish larger plants. If your ZZ plant has outgrown its pot, division is a suitable method. However, be mindful not to divide the plant too frequently, as this can cause stress and may require several years of recovery.

Steps for Dividing ZZ Plants & Rhizomes

To propagate ZZ plants through division, follow these steps to gently separate the rootball or rhizomes by hand:

Step 1: Prepare new pots – Fill new containers with a well-draining mixture of potting soil and perlite. Place enough mixture to cover the bottom of the container.

Step 2: Divide the rootball – Gently slide the entire plant out of the pot by placing your hand against the top of the soil. Tease apart the rhizomes individually or in larger clumps.

Step 3: Pot up the divisions – Set each division into a container and fill it with soil until the plants are buried at the same depth as they were in the original pot. Ensure the plants are standing upright and stabilize the rootball by gently pressing the soil around it. If needed, add more soil on top.

Step 4: Water thoroughly – Give your newly potted divisions a generous drink, ensuring that the soil is moist. Allow any excess water to drain from the pot. Fill in any empty spaces if the soil settles after watering.

Step 5: Place in bright, indirect light – Although ZZ plants can tolerate low light, they prefer a location with plenty of natural light, away from direct sunlight.

How Long Does It Take for ZZ Cuttings to Root?

While ZZ plants are relatively simple to propagate, the rooting process can be time-consuming. Even under ideal conditions of temperature and lighting, cuttings may take up to 3 to 4 months to root. It is highly recommended to wait until the roots reach a length of at least 1 inch before potting them up, which may take a few additional weeks. If the temperature falls below 75°F or there is insufficient light, the process can take up to 9 months. Be patient if the progress seems slow, but you can speed up the rooting process by using a heat mat or grow light to provide extra warmth and light.

Why Won’t My Zamioculcas zamiifolia Plant Propagate?

Several factors can affect the successful propagation of your ZZ plant. Cool temperatures, dry air, and improper watering can all impact your success rate. If your home is cooler, consider using a heat mat to provide the necessary warmth. Additionally, misting the air around the cuttings every few days can aid in overcoming dry air. Remember to maintain evenly moist rooting medium without allowing it to become excessively dry or soggy. If you are using water as the rooting medium, prevent it from evaporating below the developing roots.

How to Care for Newly Propagated ZZ Plants

It is common for newly propagated ZZ plants to droop temporarily after division or potting up rooted cuttings. Give them a few days to adjust, and they should regain their upright posture. To aid in their recovery, ensure that the soil remains moist and place them in a bright, warm area with average humidity.

Potting Up Zamioculcas zamiifolia Cuttings & Rhizomes

When it comes time to pot up your rooted cuttings, prepare containers with well-draining soil. You can use a mixture of general-purpose potting soil and perlite or opt for a cactus mix for best results. Nestle the cuttings into the soil, being careful not to damage the tender new roots, and gently pack the soil around them. The rhizomes and roots should be fully covered and stable. Give your new ZZ plants a good watering, allowing any excess water to drain. Finally, return them to a warm, bright location.
