Can you grow a ZZ plant in water forever? If you have the same question in mind then let’s find out what happens in this guide.
If you think you can grow a ZZ plant in water forever, then let us tell you that it isn’t going to be very easy and may come with a lot of challenges. This succulent is quite low maintenance and very adaptable but to know if it will survive in a liquid medium you have to learn everything included in this guide. Read along!
Can a ZZ Plant Survive in Water Long-Term?
Basically, growing plants in water is a low-maintenance and stylish way. Many tropical plants like Pothos and succulents like Snake Plants flourish well in water. But growing the ZZ plant in water is something very new to the gardening world.
So, the answer is ‘yes’, this semi-evergreen plant can grow in water but there are a few considerations to keep in mind. While it’s an excellent method for propagation and short-term growth, keeping it in water permanently comes with some challenges.
Besides, this is good news for pet owners too! They no longer need to worry about their pets scratching out the soil of houseplants. Rather, replace the water occasionally (rather than watering weekly).
Also, by eliminating soil, plants are less susceptible to pests or diseases. Furthermore, this dirt-free method can help reduce allergens in your home too. Let’s find out how to grow ZZ plants in water and overcome the challenges.
Benefits and Challenges of Growing ZZ Plants in Water
1. Roots Develop Quickly
Did you ever wonder why most people propagate plants in water first and then transfer them to soil later? Here is the secret revealed—Water is a potent regulator of plant development and induces root branching faster through a process termed ‘hydro patterning‘. Because the roots find it easier to penetrate in water than in soil!
Fact: While roots develop quickly in water, they may become more fragile compared to soil-grown roots. Water roots tend to be thinner and more delicate, making the transition to soil more difficult if attempted later.
2. Leaves Stay Healthy
As long as the water is clean, healthy, and nutritious, the leaves and stems will stay green and shiny. Because the healthier the roots grow, the longer the whole plant will maintain its health. So, since ZZ Plants store water in their rhizomes already, they can sustain themselves well in water.
In this soil-free method, there is a big plus point as well—”no pests at all!” Probably this is also one good reason for healthy leaves and stems.
Even though ZZ plants in water don’t suffer from soil pests, they are still prone to algae and bacterial growth. If the container is exposed to too much direct sunlight, algae can quickly take over, reducing oxygen in the water and harming the roots. To prevent this, use an opaque or dark-colored container instead of a clear one.
3. Growth May Slow Down
Does that sound scary? This will happen if the water does not have enough nutrients for the plant. Over time, the plant may show stunted growth, produce smaller leaves, and develop thinner stems due to a lack of essential nutrients and minerals.
The quick and easy solution here is to use store-bought liquid fertilizer for all kinds of houseplants. You can get one with a 10-10-10 NPK ratio and dilute it accordingly for a liquid medium and voilà!
Tip: If you notice your ZZ plant developing pale or yellow leaves, it may indicate a nitrogen deficiency. Adding a nitrogen-rich hydroponic fertilizer can help restore its deep green color.
4. Risk of Root Rot
One of the biggest issues is root rot! Do you know why? Imagine if you were to wear the same clothes for 6-7 days without showering or cleaning them! Exactly—that’s how plants in water feel if you don’t change the water at least every 3-4 days.
Unchanged water collects dust particles from the air making it a breeding ground for pests and diseases. These harmful pathogens feed on the plant and ultimately harm the delicate roots, leading to issues like root rot.
Do you know that some gardeners believe that adding a copper coin and a pinch of salt to the water helps prevent bacteria and algae buildup? The copper releases small amounts of ions that discourage microbial growth, keeping the water fresher for longer.
How to Grow a ZZ Plant in Water?
1. Choose Healthy Cuttings or a Small Plant
Take a good-sized (4-5 inches long) stem cutting with a few leaves or use a small division from an existing plant. Ensure the base of the cutting has at least one node submerged in water.
2. Pick the Right Container
Use a clear glass jar or vase to monitor root growth and water clarity. The rhizome must be above the water while only the roots are submerged. Plus, if you prefer a decorative touch, you can use colored glass vases to limit light exposure and reduce algae growth while maintaining an aesthetic look.
3. Change Water Regularly
Replace the water every 5-7 days to prevent bacterial growth and keep it oxygenated. Always use distilled or filtered water to avoid chlorine and mineral buildup.
4. Provide Proper Light and Conditions
Place the container in bright, indirect sunlight. Maintain a temperature range of 65-80°F (18-27°C) with moderate humidity.
5. Supplement with Nutrients
Since water lacks the essential nutrients found in soil, add a diluted liquid fertilizer once a month to sustain growth. Try using a balanced hydroponic fertilizer for the best results.
Should You Grow a ZZ Plant in Water Forever?
Hydroponics is now revolutionizing the agricultural and gardening sectors, so why shouldn’t a ZZ plant grow in water? However, it completely depends on the maintenance and care. ZZ plants can thrive for many years in water if provided with all the necessary care and supplements.
Even though ZZ plants can survive in water long-term, they will never reach their full potential size compared to those grown in soil. Soil provides a richer medium for root expansion and nutrient absorption, which supports larger and more robust growth.
But, it is always possible if you’re looking for a fun way to propagate or display a ZZ Plant hydroponically. Let us know your experience when you try this fun way of gardening!
