ZZ Plant Care: The Complete Beginner’s Guide

Why ZZ Plants Are a Great Low-Fuss Houseplant

If you’re new to houseplant care or often forget to water your greenery, ZZ plants are the perfect addition to your collection. Their thick, waxy, dark green leaves grow on upright, arching stems, and their natural tolerance for neglect makes them far more forgiving than finicky species like ferns or calatheas. ZZ plants store water in their thick, potato-like rhizomes under the soil, so they can go weeks without water if needed, making them ideal for frequent travelers, busy households, or anyone who has struggled to keep plants alive in the past.

They are also extremely adaptable to a wide range of indoor conditions, from dim office corners to bright living room windowsills. If you love low-effort plants, you may also enjoy other hardy species covered in our cast-iron plant care guide and century plant care tips, both of which share the ZZ plant’s ability to thrive with minimal intervention. While ZZ plant care is low-stakes overall, following a few simple best practices will help your plant grow full, healthy stems and avoid common beginner mistakes.

Light Requirements for ZZ Plant Care

ZZ plants are famous for their ability to survive in low-light conditions, but they will grow faster and produce more foliage with bright, indirect light. Place your ZZ plant within 3 to 5 feet of a north or east-facing window, where it will receive gentle, filtered light for most of the day, or behind a sheer curtain in a south or west-facing window to block harsh direct sun.

They can tolerate low light (such as in a hallway with only artificial overhead lighting) for months at a time, though growth will slow significantly and stems may stretch toward the nearest light source over time. Avoid placing ZZ plants in direct, unfiltered sunlight for more than 1 to 2 hours per day, as intense UV rays will scorch their leaves, causing brown, crispy patches that will not heal.

If you’re not sure if the light in your space is suitable for your ZZ plant, use the light meter feature in Sproutly to measure light levels and get personalized placement recommendations for your specific space.

How Often to Water ZZ Plants

Overwatering is the number one cause of ZZ plant death, so sticking to a consistent, infrequent watering schedule is the most critical part of zz plant care. Water your ZZ plant every 2 to 3 weeks, and always wait until the entire volume of soil in the pot is completely dry before watering again. To check soil moisture, stick your finger 2 to 3 inches deep into the soil; if it feels dry at that depth, it is safe to water. If any moisture remains, wait another 2 to 3 days and check again.

When watering, pour water slowly over the entire surface of the soil until it runs freely out of the drainage holes at the bottom of the pot. Discard any excess water that collects in the saucer under the pot within 10 minutes, as leaving the pot sitting in standing water will cause the rhizomes to rot. In the winter, when growth slows, you can extend the time between waterings to every 3 to 4 weeks, as the plant will use moisture much more slowly in cooler, darker conditions.

Sproutly tip: If you struggle to remember when to water your plants, set up custom care reminders in Sproutly tailored to your ZZ plant’s specific location and season, so you never water too early or too late.

Best Soil Mix for Healthy ZZ Plants

ZZ plants need a well-draining, porous soil mix that dries out quickly after watering, as their thick rhizomes are prone to rot if left in soggy, compacted soil for too long. A standard cactus or succulent potting mix works well for ZZ plants, as it is formulated to drain fast and avoid holding excess moisture around the roots.

If you want to make your own custom mix, combine 3 parts regular potting soil, 2 parts perlite or pumice, and 1 part orchid bark to improve aeration and drainage. Avoid using heavy, moisture-retentive mixes designed for tropical plants that hold water for long periods, as these will increase the risk of root rot.

Always plant your ZZ plant in a pot with drainage holes at the bottom, no matter what soil mix you use. If you want to use a decorative pot without drainage holes, keep your ZZ plant in its plastic nursery pot and place it inside the decorative pot, removing it to water and letting it drain completely before putting it back.

Fertilizing ZZ Plants: What You Need to Know

ZZ plants are not heavy feeders, so they do not need frequent fertilizing to stay healthy. In fact, over-fertilizing can burn their roots and cause brown leaf tips, so it is better to under-fertilize than over-fertilize when it comes to zz plant care.

Feed your ZZ plant once every 2 to 3 months during the active growing season (spring and summer) with a balanced, water-soluble houseplant fertilizer diluted to half the recommended strength. Apply fertilizer only to damp soil, never to dry soil, as this can burn the delicate root hairs. Do not fertilize your ZZ plant in the fall or winter, as the plant is dormant and will not use the extra nutrients, which can build up in the soil and cause damage over time.

If you notice white, crusty deposits building up on the surface of the soil, this is a sign of excess fertilizer salts. Flush the soil by running water through the pot for 2 to 3 minutes until the water runs clear out of the drainage holes, to remove built-up salts and prevent root burn.

ZZ Plant Propagation: 2 Simple Beginner Methods

ZZ plant propagation is easy for even first-time plant parents to pull off, with two reliable methods that require no special tools or experience. Whether you want to grow new plants to share with friends or fill out an existing ZZ plant, both methods have high success rates with minimal effort.

Method 1: Stem Cuttings in Water

This method is ideal if you only have a small cutting to work with, or if you want to watch roots grow over time.

1. Use a clean, sharp pair of pruning shears to cut a 4 to 6 inch section of a healthy ZZ stem, making the cut just below a leaf node (the bump on the stem where leaves grow from). Remove the bottom 2 to 3 leaves from the cutting, leaving at least 2 to 3 leaves at the top.
2. Let the cut end of the stem dry out and form a callus for 24 hours, which prevents rot when the cutting is placed in water.
3. Fill a clear glass or jar with room-temperature filtered water, and place the cut end of the stem in the water, making sure no leaves are submerged.
4. Place the jar in a spot with bright, indirect light, and change the water every 3 to 5 days to prevent algae growth.
5. You will see small rhizomes and roots forming at the base of the cutting after 2 to 3 months. Once the roots are at least 1 inch long, you can pot the cutting in a well-draining succulent mix, and care for it following standard zz plant care guidelines.

Method 2: Rhizome Division

This method is faster than stem cuttings, and works best if you have a mature ZZ plant that is ready to be repotted.

1. Water your ZZ plant 1 to 2 days before dividing it to soften the soil and make it easier to remove the plant from the pot.
2. Gently tip the pot on its side and slide the entire root ball out. Use your hands to brush away excess soil from the rhizomes and roots.
3. Look for natural separations between clumps of rhizomes, where each clump has its own set of stems and roots. Use a clean, sharp knife to cut through the rhizome connecting the clumps, if needed, making sure each division has at least 2 to 3 healthy stems and a portion of rhizome with intact roots.
4. Let the cut surfaces of the divided rhizomes dry out and callus for 24 hours to prevent rot when repotted.
5. Pot each division in its own pot with well-draining succulent mix, and water lightly. Wait 1 to 2 weeks before watering again to allow the roots to establish, then resume regular care.

If you are not sure if your cuttings are developing healthy roots as you propagate, take a photo of the growth and use Sproutly to identify any early signs of rot or stunted growth, so you can adjust your process as needed.

Common ZZ Plant Care Problems and How to Fix Them

Even though ZZ plants are extremely hardy, they can develop a few common issues if their care needs are not met. Most problems are easy to fix if caught early.

• Yellow leaves: The most common cause of yellow ZZ plant leaves is overwatering. If you see yellow leaves, check the soil moisture. If the soil is still wet a week after watering, stop watering immediately and let the soil dry out completely before watering again. If multiple leaves are turning yellow and the stems feel mushy at the base, you may have root rot. Remove the plant from the pot, cut away any soft, brown, rotting rhizomes and roots, repot in fresh, dry soil, and wait 2 weeks before watering again. Yellow leaves can also be caused by extended exposure to direct sunlight, so move the plant to a shadier spot if you notice yellowing alongside brown, crispy leaf edges.
• Drooping stems: Drooping stems are usually a sign of either severe underwatering or overwatering. If the soil is completely dry and the leaves feel crisp, water the plant thoroughly, and it should perk up within 24 to 48 hours. If the soil is wet and the stems feel soft, you are overwatering, and should let the soil dry out completely before watering again.
• Brown leaf tips: Brown leaf tips are most often caused by excess fertilizer buildup, very dry air, or occasional underwatering. If you see white crust on the soil surface, flush the soil as described in the fertilizing section. If the air in your home is very dry (below 40% humidity), you can place a humidifier near the plant or set it on a pebble tray filled with water to raise ambient humidity, though ZZ plants tolerate average household humidity well and usually do not need extra humidity to thrive.
• Slow growth or stretched stems: If your ZZ plant is not producing new leaves in the spring and summer, or if new stems are long and spindly with wide gaps between leaves, it is not getting enough light. Move the plant to a spot with brighter, indirect light to encourage fuller growth.

If you notice unusual symptoms on your ZZ plant that you can not identify, use Sproutly to scan the plant and get a diagnosis and personalized fix for the issue before it spreads to the rest of the plant.

FAQ

Are ZZ plants pet-safe?

ZZ plants are not considered pet-safe, as their leaves contain compounds that can cause stomach upset if ingested by cats or dogs. If you have curious pets, keep your ZZ plant on a high shelf out of their reach, and use Sproutly to look up pet-safe houseplant alternatives if needed.

How fast do ZZ plants grow?

ZZ plants are slow-growing, especially in low-light conditions. With ideal zz plant care, you can expect 2-3 new leaves per growing season, and a mature indoor ZZ plant can reach up to 3 feet tall over several years.

Do ZZ plants need to be repotted often?

ZZ plants prefer being slightly root-bound, so you only need to repot them every 2-3 years, or when you see roots growing out of the drainage holes of their current pot. Use a well-draining soil mix when repotting to avoid root rot. When you do repot, choose a pot that is only 1 to 2 inches larger in diameter than the current pot, as an oversized pot will hold excess soil moisture that can lead to rot.

Can I keep a ZZ plant outdoors?

ZZ plants can be kept outdoors in warm, shaded areas that don’t drop below 60°F (15°C). Avoid direct outdoor sunlight, as it can scorch their leaves, and bring them back indoors before cold weather hits. If you live in a climate with high humidity, make sure the soil dries out completely between waterings to prevent rot, as outdoor ZZ plants are more prone to fungal issues in damp conditions.
