Growing indoor plants in water is a unique and fascinating way to care for your plants. Hydroponic gardening, or growing plants in water, has gained popularity due to its simplicity and low-maintenance nature. Water-growing plants can thrive in almost any indoor space, adding an elegant touch to your decor while improving air quality and promoting a natural ambiance.
In this comprehensive guide, we’ll walk you through the process of growing indoor plants in water. From selecting the right plants to setting up your hydroponic system and caring for your water-grown plants, this guide will provide you with all the information you need to successfully grow plants in water and enjoy a beautiful, thriving indoor garden.
1. Why Grow Plants in Water?
Growing plants in water has several benefits, making it an attractive choice for both beginner and experienced gardeners. Here are some of the reasons you might consider growing your plants in water:
A. Easy Maintenance
Plants grown in water require less frequent attention compared to soil-grown plants. You won’t have to worry about the mess of soil or the need to water regularly. Simply change the water every couple of weeks, and your plants will thrive.
B. Clean and Mess-Free
Water-growing plants are virtually mess-free. There’s no dirt to spill or manage, making them ideal for small spaces like apartments or offices. You can even grow them in decorative containers, creating a clean and modern look.
C. Less Pests
Without soil, water-grown plants are less likely to attract pests like soil-borne insects, including gnats and aphids. This makes them an excellent choice for those who want to avoid common indoor plant pests.
D. Beautiful Aesthetic
Water-grown plants often have a sleek, modern look. Their roots are exposed, allowing you to see the unique and beautiful growth patterns. Whether you use clear glass containers or creative vases, plants in water can act as living decor, adding beauty and freshness to any room.
E. Improved Growth
Water-grown plants can sometimes grow more quickly than soil-grown plants because they have constant access to nutrients, oxygen, and water. Their roots can grow freely in the water, leading to a stronger and healthier plant.
2. Choosing the Right Plants for Water Growth
While most plants are grown in soil, many indoor plants thrive when grown in water. However, not all plants can be successfully grown in water. The best plants for water growth are those that naturally grow in aquatic environments or can adapt to water culture.
A. Best Plants for Growing in Water
These are some of the most popular and easiest-to-grow indoor plants in water:
1. Pothos (Epipremnum aureum)
Pothos is one of the most popular plants for growing in water. Known for its trailing vines and heart-shaped leaves, it thrives in water and can grow in low light, making it perfect for beginners.
- Light Needs: Indirect light is ideal.
- Watering: Change the water every week to keep it fresh.
- Tip: Prune the vines regularly to encourage bushier growth.
2. Spider Plant (Chlorophytum comosum)
Spider plants are another excellent choice for growing in water. Their long, arching leaves and small offshoots (called “pups”) make them a fun and beautiful addition to your indoor garden.
- Light Needs: Bright, indirect light is best.
- Watering: Keep the water level high enough to cover the roots, changing the water every 7-10 days.
- Tip: Spider plants can be propagated in water by placing the pups in water until they grow roots.
3. Lucky Bamboo (Dracaena sanderiana)
Lucky bamboo is a popular water plant that is often grown in decorative glass containers. It’s known for its good fortune symbolism and is easy to care for in water.
- Light Needs: Indirect light is perfect.
- Watering: Change the water every two weeks and make sure the roots stay submerged.
- Tip: Lucky bamboo can also grow in soil, but growing it in water is ideal for indoor environments.
4. Coleus (Plectranthus scutellarioides)
Coleus is an ornamental plant known for its vibrant, multicolored foliage. When grown in water, it provides an eye-catching splash of color and thrives in a variety of light conditions.
- Light Needs: Bright, indirect light.
- Watering: Change the water weekly to ensure it remains clean and clear.
- Tip: Trim the stems periodically to encourage fresh, new growth.
5. English Ivy (Hedera helix)
English Ivy is a popular trailing plant that can easily be grown in water. It’s a great choice for hanging containers or decorative vases.
- Light Needs: Bright, indirect light.
- Watering: Change the water once a week.
- Tip: English Ivy can grow quickly, so be prepared to prune it to keep it manageable.
6. African Violet (Saintpaulia)
African violets are small flowering plants that can also grow in water. These plants have fuzzy, vibrant green leaves and produce delicate flowers in shades of purple, blue, and white.
- Light Needs: Bright, indirect light is ideal.
- Watering: Keep the roots submerged in water and change the water every 10-14 days.
- Tip: Keep the leaves dry to avoid rot. Water the roots only.
7. Mint (Mentha)
Mint is an aromatic herb that grows well in water. It’s easy to propagate in water and adds a fresh, herbal fragrance to your space.
- Light Needs: Bright, indirect light.
- Watering: Change the water every week.
- Tip: Mint grows quickly, so it’s important to prune it regularly to prevent it from becoming too leggy.
B. Plants Not Suitable for Water Culture
Some plants do not grow well in water due to their specific needs for soil or their inability to thrive without it. Examples include:
- Most tropical plants that require specific soil conditions.
- Cacti and succulents that prefer dry conditions and may suffer from root rot in water.
- Plants with large root systems, as they may require too much space and nutrients that water cannot provide alone.
3. Setting Up Your Water Garden
Once you’ve chosen your plants, it’s time to set up your water garden. Whether you’re using a simple jar or a more elaborate setup, follow these steps to ensure your plants thrive.
A. Choose the Right Container
Selecting the right container is crucial for the success of your water garden. The container should be:
- Clear glass: Clear glass allows you to see the roots and adds a decorative touch. You can use glass jars, vases, or decorative bowls.
- Wide opening: A container with a wide opening allows the plant’s roots to grow and spread out.
- Clean: Make sure your container is clean before placing the plant inside to avoid any harmful bacteria.
B. Fill the Container with Water
Use filtered or distilled water to fill your container. Tap water may contain chlorine and other chemicals that can harm your plants. Fill the container so that the roots are submerged but the leaves are above the water line.
C. Adding Stones or Pebbles
Adding stones or pebbles to the bottom of your container is optional, but it can help stabilize the plant and provide additional visual interest. If you use pebbles, make sure they don’t obstruct the roots’ ability to absorb water.
D. Positioning the Plants
Place the plants in the container, ensuring the roots are submerged in water but that the plant’s stem or leaves don’t touch the water. You can use decorative rocks, wire, or other materials to secure the plant in place. For trailing plants, you can use a pot or a container that allows the vines to spill over the sides.
4. Caring for Water-Grown Plants
Caring for plants grown in water is straightforward, but there are a few essential maintenance tasks to keep in mind:
A. Changing the Water
It’s essential to change the water regularly to prevent stagnation and the growth of algae or bacteria. Depending on the plant species, change the water every 7-14 days. Make sure the roots are well-submerged and the water is clear and fresh.
B. Adding Nutrients
While plants in water don’t require soil, they still need nutrients to grow. You can add liquid houseplant fertilizer to the water once a month to ensure your plants receive the necessary nutrients. Be sure to dilute the fertilizer to half the recommended strength, as water-grown plants are more sensitive to fertilizers.
C. Pruning and Cleaning
Prune your water plants regularly to remove dead or damaged leaves. This will encourage new growth and keep the plant looking tidy. Clean the container and any decorative stones every month to prevent buildup of dirt or algae.
D. Monitoring Light and Temperature
Place your water-grown plants in a location that receives bright, indirect light. Avoid direct sunlight, as this can cause algae growth or harm the plant. Keep the temperature in the range of 60°F to 75°F (15°C to 24°C), as most indoor water plants prefer moderate temperatures.
5. Troubleshooting Common Problems
While growing plants in water is generally easy, you may encounter a few issues. Here are some common problems and how to address them:
A. Algae Growth
Algae can grow in the water if the container is exposed to too much light. If you notice green slime or algae on the walls of your container, move it to a shadier spot or reduce the amount of time it spends in direct light. You can also clean the container with a diluted vinegar solution to remove algae.
B. Yellowing Leaves
If the leaves of your water-grown plants turn yellow, it could be due to a lack of nutrients or overwatering. Consider adding a diluted fertilizer to the water or trimming back yellowing leaves to encourage new growth.
C. Root Rot
Root rot can occur if the plant is overwatered or if the water is stagnant for too long. To prevent this, change the water regularly and ensure that the plant’s roots are not sitting in water that is too deep or murky. Trim off any rotting roots to promote healthy new growth.
