It is worth noting that every indoor environment is different, and the temperature requirements for ZZ plants may vary slightly depending on factors such as humidity levels, air circulation, and overall climate conditions.
Humidity Preferences

ZZ plants prefer indoor humidity levels between 40 and 50 percent for optimal growth. While they can tolerate a wide range of humidity conditions, maintaining a moderate humidity level within this range helps promote their overall health and appearance.
High humidity can lead to the development of mold and root rot, while low humidity can cause the tips of their leaves to turn brown.
To ensure the ideal humidity for your ZZ plant, there are a few methods you can employ. One option is to group your plants together, as they collectively release moisture into the air through transpiration, creating a more humid microclimate.
Placing your ZZ plant on a tray filled with pebbles and water can also help increase humidity. As the water evaporates, it creates moisture in the air surrounding the plant.
Additionally, using a humidifier in the room where your ZZ plant is located can help maintain the desired humidity level.
It’s important to note that while ZZ plants prefer moderate humidity, they are fairly adaptable and can tolerate slight fluctuations. However, consistently providing humidity levels within the recommended range will help ensure their optimal growth and vitality.
By monitoring and adjusting the indoor humidity of your ZZ plant’s environment, you can create a more favorable condition for its overall well-being.
Light Conditions

ZZ plants thrive in medium to bright indirect light and should be protected from direct sunlight. As native to Eastern Africa, where they grow in diverse habitats ranging from grasslands to humid evergreen forests, ZZ plants have adapted to various light intensities.
They can tolerate lower light conditions but will thrive and grow more vigorously in brighter light. Placing your ZZ plant near a north, east, or west-facing window is ideal, as they will receive the right amount of sunlight without being exposed to the harsh midday sun.
When it comes to indoor lighting, ZZ plants can also adapt well to artificial lights. If you don’t have access to natural light, using fluorescent or LED grow lights can provide the necessary light intensity for their growth.
Position the lights about 12 to 18 inches away from the plant to mimic natural light conditions. Keep in mind that ZZ plants are not suited for direct exposure to intense, full sun, as it can scorch their leaves.
Signs of Inadequate Light
If your ZZ plant is not receiving enough light, it will start to show signs of inadequate lighting. The most common signs include stunted growth, leaf elongation, and a lack of new growth.
The plant may also appear leggy or have smaller leaves. If you notice these signs, it’s a good indication that your ZZ plant needs more light. Consider moving it to a brighter location or providing supplemental artificial lighting to support its growth.
Watering and Care Tips

ZZ plants have low water requirements and should be watered every 2-3 weeks, allowing the soil to dry out between waterings. Overwatering can lead to root rot, so it’s important not to overdo it.
To determine when to water your ZZ plant, simply insert your finger about an inch into the soil. If it feels dry, it’s time to water. If it still feels moist, it’s best to wait a little longer.
When watering your ZZ plant, it’s important to pour water directly into the soil rather than on the leaves. This helps prevent moisture-related diseases and keeps the plant’s foliage healthy.
It’s also a good idea to use room temperature water, as cold water can shock the roots and hinder their growth.
In addition to proper watering, ZZ plants benefit from regular fertilization. Use a balanced, water-soluble fertilizer formulated for houseplants.
Apply the fertilizer according to the instructions on the packaging, typically every 2-3 months during the growing season. Be careful not to exceed the recommended dosage, as this can burn the plant’s roots.
