The Ultimate Guide to Repotting ZZ Plants

If you’ve taken the time to provide your houseplants with the perfect blend of light, water, and nutrients, it’s only a matter of time before they outgrow their pots. And the popular ZZ plant is no exception. But when should you repot a ZZ plant? Should you wait until it becomes root bound, or take action before it reaches that stage? In this comprehensive guide, we’ll explore everything you need to know about repotting a ZZ plant.

Getting to Know ZZ Plants

ZZ plants are beloved for their distinctive upright, zigzag-shaped foliage. Their scientific name, Zamioculcas zamifolia, hints at their resemblance to cycads, specifically the Zamia spp. However, despite this visual similarity, ZZ plants are actually related to elephant ears, anthurium, and philodendron, which are all part of the aroid family. Like their aroid relatives, ZZ plants have evolved to store water in their rhizomes, enabling them to thrive in the arid conditions of their native Eastern Africa.

While ZZ plants grow more slowly indoors than in their natural habitat, they can still reach heights of 3-4 feet and spread up to 3 feet across.

Signs that Your ZZ Plant Needs Repotting

Unlike some houseplants that thrive when root bound, ZZ plants prefer a bit more space. Their large underground rhizomes require ample room to grow. So, how can you tell if your ZZ plant is ready to be repotted? Here are a few signs to look out for:

  • Roots poking out of the pot’s bottom or surfacing above the soil
  • Excessive water draining out of the pot after watering
  • Stunted growth or pale, limp foliage

If you notice any of these indicators, it’s time to repot your ZZ plant. Typically, ZZ plants should be repotted every two years to ensure their continued health and vitality.

The Repotting Process

Repotting a ZZ plant is essential for preventing root rot and ensuring the plant can access sufficient water, air, and nutrients. Here’s a step-by-step guide to help you navigate the repotting process:

  1. Choose the Right Pot: Select a pot that is one size larger than the current one. It’s important not to opt for a pot that is too large, as this can lead to excessive soil moisture, putting the rhizomes at risk of root rot.

  2. Prepare for Repotting: Before removing the ZZ plant from its current pot, don a pair of gloves to protect your skin from the calcium oxalate produced by ZZ plants, which can cause irritation. Flip the plant upside down and gently pull it out of the pot, taking care not to damage the roots.

  3. Add Fresh Soil: Fill the new pot about one-third full with fresh potting soil. Place the plant on top of the soil and add more around the plant until it’s secure. Gently pat down the soil and water the plant thoroughly.

An Alternative Approach to Repotting ZZ Plants

If you don’t have a larger pot or simply prefer not to repot your ZZ plant, there’s another option: division. Here’s how you can divide your pot-bound ZZ plant:

  1. Remove the Plant: Carefully remove the plant from its current pot, gently washing away the soil from the rhizomes to get a better view.

  2. Separate the Rhizomes: Use a sterile knife to separate the rhizomes. If you’re lucky, you might find well-developed rhizomes that are only minimally attached to the parent plant. In this case, a single clean cut will release the pup from the parent. Look for rhizomes that have a stem.

  3. Divide and Replant: If the rhizomes are more intertwined, make clean cuts to divide the plant into smaller sections. Allow the divided ZZ plant to rest for a few hours or overnight before replanting.
