ZZ plants (Zamioculcas zamiifolia) are popular indoor plants known for their beauty and resilience. But, like any plant, they need proper care to thrive.
Watering is one of the most important factors for keeping your ZZ plant healthy.
Let’s explore how to water a ZZ plant the right way, including tips on bottom watering and avoiding common mistakes.
Why Proper Watering Matters for ZZ Plants
ZZ plants are drought-tolerant and store water in their thick stems and roots. They don’t need frequent watering but overwatering can harm them.
overwatering can cause root rot, yellowing leaves, and even kill the plant. On the other hand, underwatering can lead to droopy stems and wrinkled leaves. So it’s important to find a balance.
Quick Tip: Always let the soil dry out between waterings. ZZ plants prefer being too dry over being too wet
How Often Should You Water a ZZ Plant?
General Watering Schedule
- Indoor ZZ Plants: Water every 2-3 weeks, depending on humidity and light levels.
- Outdoor ZZ Plants: Water weekly if grown in hot, dry conditions.
Seasonal Adjustments
- In summer, ZZ plants may need water more often due to faster evaporation.
- In winter, reduce watering since the plant grows slower.
Pro Tip: Always consider your plant’s environment. Warmer, sunnier spots may need more water, while cooler, shaded areas require less.
How to Water a ZZ Plant: Top Watering vs. Bottom Watering
Bottom Watering Method for ZZ Plants
Bottom watering is a method when you let the plant absorb water from the bottom. This ensures even watering and reduces the risk of overwatering.
Benefits of Bottom Watering
- Prevents soggy soil on the surface.
- Helps the plant absorb water evenly.
- Keeps leaves and stems dry, reducing the chance of mold.
Step-by-Step Guide to Bottom Watering
- Fill a tray or basin with water.
- Place the pot in the tray so the water touches the bottom of the soil.
- Leave the plant for 20-30 minutes.
- Remove the pot and let it drain.
Top Watering Method for ZZ Plants
Top watering means pouring water directly onto the surface of the soil. This method is quick and simple, making it the most common way to water houseplants.
Benefits of Top Watering
- Ensures that water reaches the roots quickly.
- Flushes out excess salts and minerals that may build up in the soil.
- Allows you to visually monitor how much water is being added.
Step-by-Step Guide to Top Watering
- Use room-temperature water to avoid shocking the plant.
- Pour water slowly and evenly over the soil until it begins to drain out from the bottom of the pot.
- Wait a few minutes, then pour out any excess water collected in the saucer to prevent root rot.
- Check that the topsoil feels evenly moist but not waterlogged.
