How fast does a ZZ plant grow?

We all know that the ZZ plants are slow-growing plants. But with proper care, they can achieve a height of 15-30 cm and 2-3 cm in width in 30 days, by producing new shoots. These new shoots indicate that you are caring enough about your plant. This growth can be observed only if the plant is in moderate weather conditions.

As we discussed above, 5 feet which is the maximum height of a ZZ plant can be observed in suitable conditions. These plants can produce up to 6-8 stems in the growing seasons that grow vertically up and increase the plant’s height. But these plants hardly continue to grow after the summer. Winters are the dormant seasons of the ZZ plants. They completely stop their growth until the early spring arrives.

If your plant is not producing new shoots even in the early summer, then you need to check the care tips for growing your ZZ plant.

Factors affecting your ZZ plant’s growth

Have you ever felt that you are caring enough for your ZZ plant, and it is not growing well? Then do not lose your mind. Proper caring means giving the plant what it needs at the right time, not on a schedule.

Some factors that affect your plant if not you do not provide them efficiently to your plant. So, let us explore the factors given below!

1. Not giving proper water to ZZ plants

Watering ZZ plants on a schedule or providing more or less amount of water will make your plant grow slowly. Over watering and under watering makes your plant feel uncomfortable and thus result in the fall of its growth rate.

2. Not giving enough light to ZZ plants

Placing your plant in the hot sun will affect the foliage and the growth of the plant. Overexposure to the sun will damage your plant. It causes sunburns and dryness in the plant. So, do not let them out in the hot sun. Placing them in shade slows down the growth of your ZZ plant.

3. Lack of Nutrition in ZZ plants

Leaving your plant in the same pot for more than 3 years without changing the soil, will make the soil futile. Due to the lack of nutrients, the plant will not be able to grow in a better way. We can also observe the same case in the plants that are not fertilized for months.

4. Size of the rhizome in ZZ plants

Rhizomes are responsible for the growth of plants. Rhizome size increases with time. If the pot does not have enough space to encourage the growth of the rhizome and stops its growth, it shows the result in the plant. Repot your plant every 3 years to avoid this problem.

5. Not maintaining the temperature in ZZ plants

It is a bit difficult to maintain the plant in a fixed temperature range in every season. But if you do not maintain it, your plant may not grow faster. Your ZZ plant does not like to stay in cooler temperatures as it undergoes dormancy in temperatures below 60 degrees Fahrenheit. If the temperature is above 80 degrees Fahrenheit, your plant loses moisture in them, and thus it stops growing.

Why is it so important to encourage the growth of a ZZ plant and how can you do it? Let’s check it out below!

How to encourage the growth of a ZZ plant?

To maintain a healthy ZZ plant or to fasten the growth of your ZZ plant, you should know some tips. Saving your plant from a bad environment and providing proper care will help in its growth and the tips that we have mentioned below can help you to make your ZZ plant grow even faster!

1. Providing a good amount of light to your ZZ plants

ZZ plants are well-known as semi-succulents and they thrive very well in warm conditions. So make them sit in a bright place with indirect sunlight. Remember providing enough sunlight does not mean leaving them in a hot place. These plants get damaged when they are exposed to the full sun.

The growth rate may fall even if they are left in the hot sun. That is why providing adequate sunlight plays a crucial role to improve the growth of your ZZ plants. These plants can enjoy being under direct sun for not more than 2 hours, in the early mornings and the early evenings. You can even place them on a windowsill to let them absorb light during that time. But, you need to cover the window glass with a curtain in the afternoon.

Make sure your plant is getting enough light daily, it is okay to face low light when the climate is cool. But during the falls and in the winters you need to use a plant light which helps to provide enough light to your plant.


2. Fertilization can help your ZZ plants

Fertilization helps your ZZ plants to achieve better heights in a short span. As these ZZ plants are slow-growing plants, we often delay fertilizing them, due to the fear of sunburns. But, fertilizing at least once or twice during the growing season will help the plant to absorb adequate nutrients which the soil mix may not provide.

ZZ plants should be repotted after 2 years to make the soil mix not go out of nutrients. Remember fertilizing your ZZ plant more than its needs will damage the root system and thus the growth.


3. Providing proper water at the right time

Although your ZZ plant can tolerate being under-watered for a while, it may seriously affect the growth of that plant. Because the dried plants never tend to grow. Even over watering your ZZ plants can lead to some disease which has even worse effects on the plant’s growth. Because the plants which have rotten roots will not continue to grow.

You need to water your ZZ plants adequately whenever it is needed.
To provide proper water to your ZZ plant at the right time, you need to dip your finger in the soil mix about an inch deeper to check the wetness of the soil. If you feel that the soil is dry then water your plant only on top of the soil slowly. Let the soil and the root system absorb the water and send the excess water out through the drainage system.

This is the correct method of watering a ZZ plant, which helps the plant to thrive better. Do not water the plant when the soil is wet. It leads to an overwatered ZZ plant. If you ignore watering your ZZ plant, even if the soil is dry enough to take a drink, your plant is going to face the problems caused by the underwatering.


4. Maintaining the temperatures for ZZ plants

ZZ plants are hard plants, it is said that they can tolerate low temperatures. But, you need to maintain your ZZ plant in suitable temperatures, to improve its growth. ZZ plants prefer warm temperatures to live in.

Temperatures between 70-80 degrees Fahrenheit will help the plant to achieve better growth. Neither the high temperature nor the low temperatures will make your plant feel comfortable. But the climate may not be the same, so better use some plant heaters to increase the temperature in cool climates. Place your plant in a cool place during the hot summers.

5. Potting and repotting the ZZ plants


Using a better quality pot to plant your ZZ plant is also a considerable thing when you want your plant to grow faster. Plastic pots or glazed pots may not work better as clay pots, unglazed ceramic pots or unfinished terracotta pots do. The porous walls of these pots allow the air into the soil and help it to dry faster. Select a pot with a good drainage system to avoid diseases in the plants.

Repot your ZZ plant every 2-3 years with fresh soil mix and use a pot that is 1-2 inches larger than the old pot. ZZ plant’s growth depends on the growth of its rhizome, which lies under the soil mix. If there is not enough space to grow, the rhizome stops growing, which results in the growth of the plant. Also, a fresh soil mix helps the plant get enough nutrients. Remember, the pot which is too large when compared to the size of the rhizome and is filled with the soil mix holds the water for a long time which is not good for the growth of your plant.
