How to Water a ZZ Plant: Frequency & Timing
Zamioculcas zamiifolia, or the ZZ plant, is a popular, tropical perennial houseplant native to Eastern Africa. It has attractive, glossy, dark green leaves, as well as air-purifying properties. The ZZ plant is also a low-maintenance and easy-to-grow plant, which makes it a great option for newbies or seasoned plant enthusiasts looking for an undemanding indoor plant. ZZ plants, belonging to the succulent family, are incredibly drought tolerant.
However, they have specific watering needs. So, knowing how to water a ZZ plant is key to your plant's well-being. This guide delves into the specifics of watering a ZZ plant, helping you ensure it thrives and looks its best.
ZZ Plant: Watering Requirements
ZZ plants are resilient members of the succulent family. They have unique watering needs for optimal health. ZZ plants thrive best in well-draining soil with proper aeration to prevent waterlogging. This section explores the requirements that set ZZ plants apart from other indoor houseplants and lays the foundation for effective watering practices.
How Do You Know If a ZZ Plant Needs Water?
ZZ plants, being succulents, have unique characteristics that can guide you in recognizing the right time for watering. Here's how to assess ZZ plant water needs:
ZZ plants prefer their soil to dry out slightly between waterings. Stick your finger into the soil up to an inch deep. If it feels dry, it's time to water. Consider also using a digital moisture meter to get accurate results.
ZZ plants store water in their rhizomes (underground stems), allowing them to withstand drought periods. If the leaves start drooping slightly, it may indicate the plant is thirsty. However, ZZ plants are resilient, and slight drooping is normal. Severe drooping leaves may indicate underwatering.
Gently squeeze a few leaves between your fingers. If they feel firm, the plant likely has enough water. In contrast, soft or limp leaves may indicate that it's time to water.
Be mindful of seasonal changes. During the active growing season, typically spring and summer, your ZZ plant may require more frequent watering. In contrast, reduce watering during the dormant period in fall and winter.
Can I Use Succulent Soil for My ZZ Plant?
Yes! Succulent soil, with its excellent drainage properties, is a suitable choice for ZZ plants. It mimics the natural conditions of their native environments, preventing waterlogged roots and associated issues.
How to Water Your ZZ Plant
When it comes to watering a ZZ plant variety, including a Black Raven ZZ plant, there are several methods to suit different needs and preferences. Each watering approach is tailored to the unique needs of ZZ plants and ensures your plant receives the hydration it craves for optimal vitality and growth.
Bottom Watering: Can I Bottom Water My ZZ Plant?
Bottom watering is a fantastic technique for ZZ plants, providing a targeted and efficient way to nourish the roots. Follow these steps for successful bottom watering:
- Place your ZZ plant's pot in a saucer or tray large enough to accommodate water without overflowing.
- Fill the plant tray/saucer with water, allowing the plant to absorb moisture from the bottom up.
- Monitor absorption for around 10 minutes, ensuring the plant's roots absorb water without sitting in excess.
- Remove excess water from the tray if the soil is moist.
- Add more water to the tray if the soil is still dry.
- Wait for 20 or more minutes and discard excess water to prevent overwatering.
Watering Over the Soil
Consider watering your ZZ plant over the soil if you prefer conventional watering. Here's how to do it:
- Using a watering can pour water over the soil. Alternatively, placing your ZZ plant under a tap ensures an even distribution.
- Add water to the pot until it begins overflowing from the drainage holes.
- If you place a tray under the plant's pot when watering, remove all the collected water afterwards. Avoid letting your plant sit in water, as this may cause root rot.
- If you watered it directly under a tap, ensure the water stops running from the bottom before returning it.
Should I Soak My ZZ Plant and When?
Your ZZ plant may occasionally benefit from a thorough soak, especially when the soil is completely dry. In such a case, consider the bath watering technique, which involves the following steps:
- Fill a large bathtub, basin or bucket with lukewarm water.
- Gently place the ZZ plant pot in the water and stop where the plant's stem begins. Ensure all the soil is under water to allow for moisture absorption.
- Wait for the water to stop bubbling.
- Lift the plant pot and allow excess water to drain off.
- To prevent overwatering and root rot, place your ZZ plant back on the tray and ensure it isn't still sitting in water after an hour.
Is a Self-watering Pot Good for ZZ Plants?
Yes, a self-watering pot can be beneficial for ZZ plants. The self-watering feature helps maintain consistent moisture levels, ensuring optimal hydration for the ZZ plant without the risk of overwatering. This can be particularly advantageous if you find it challenging to follow a regular watering schedule, due to traveling, or for ZZ plants in environments with fluctuating humidity levels.
