- Propagation Success: It's an excellent way to propagate existing plants, giving you more greenery for free!
- Pest Control: Many soil-borne pests are eliminated when you grow plants in water.
- Aesthetic Appeal: The visible root systems can be incredibly beautiful and add a modern, minimalist touch to your decor.
- Air Purification: Like their soil-bound counterparts, many of these plants are excellent air purifiers.
Top Indoor Plants That Can Be Grown in Water
Here's a detailed look at some of the best and most readily available plants that flourish in water:
1. Pothos (Epipremnum aureum)
Pothos, often called Devil's Ivy, is arguably the king of houseplants that can be grown in water. Its trailing vines and heart-shaped leaves come in a variety of cultivars, including Golden Pothos, Marble Queen, Neon Pothos, and Jade Pothos.
How to grow: Take stem cuttings that are at least 4-6 inches long, ensuring each cutting has at least one leaf node (the bump on the stem where a leaf grows from). Remove the lower leaves to prevent them from rotting in the water. Place the cuttings in a jar or vase filled with water, ensuring the leaf nodes are submerged. Keep it in bright, indirect light. Roots should appear within a few weeks.
Maintenance: Change the water every 1-2 weeks to keep it fresh and prevent bacterial growth. If the water level drops, top it up.
2. Spider Plant (Chlorophytum comosum)
Spider plants are known for their easy care and the "spiderettes" or baby plants they produce. These babies can be easily propagated in water.
How to grow: Gently detach a spiderette from the mother plant. If it has tiny roots already, great! If not, place the base of the spiderette in a small jar or glass of water, ensuring the base is submerged. Bright, indirect light is ideal.
Maintenance: Change the water weekly. Once roots are well-established (about 1-2 inches long), you can either keep it in water or pot it in soil.
3. Philodendron (Various species, e.g., Heartleaf Philodendron)
Similar to Pothos, Philodendrons, especially the heartleaf varieties, are exceptionally well-suited for water propagation. Their vining habit and attractive foliage make them a popular choice.
How to grow: Take stem cuttings, similar to Pothos, ensuring a leaf node is present. Remove lower leaves and place the cutting in water. They prefer bright, indirect light.
Maintenance: Regular water changes (every 1-2 weeks) are crucial. Keep the leaf nodes submerged.
4. Chinese Evergreen (Aglaonema)
Chinese Evergreens are prized for their striking leaf patterns and their tolerance for lower light conditions, making them a great option for less sunny spots in your home.
How to grow: Take stem cuttings from a healthy plant. Ensure the cutting has at least one or two nodes. Place the cut end in water. While they can tolerate lower light, bright, indirect light will encourage faster growth.
Maintenance: Change the water regularly. You'll notice roots forming from the leaf nodes.
5. Lucky Bamboo (Dracaena sanderiana)
Despite its name, Lucky Bamboo is not actually a bamboo but a type of Dracaena. It's a classic for water culture and is often associated with good luck and prosperity.
How to grow: Lucky Bamboo is typically sold already rooted or as cuttings. If you have a cutting, place it in a container with a few inches of water. They do well in various light conditions but avoid direct sunlight.
Maintenance: Use distilled or filtered water if possible, as they can be sensitive to chemicals in tap water. Change the water weekly and ensure the roots remain submerged.
6. Peace Lily (Spathiphyllum)
Peace Lilies are known for their elegant white blooms and their ability to signal when they need water by dramatically drooping their leaves. While they prefer to be potted, they can also be successfully grown in water, especially for propagation.
How to grow: You can take stem cuttings or divide a plant. Place the cut end or the divided section in water, ensuring the base is submerged. They prefer low to medium indirect light.
Maintenance: Change the water frequently, every few days, as Peace Lilies can be prone to root rot if the water becomes stagnant.
7. English Ivy (Hedera helix)
English Ivy is a vigorous climber or trailing plant that can add a lush, cascading effect to your home.
How to grow: Take cuttings of about 4-6 inches, making sure to include a leaf node. Remove the lower leaves and place the cutting in water. They do best in bright, indirect light.
Maintenance: Keep the leaf nodes submerged and change the water regularly.
8. Monstera Deliciosa (Swiss Cheese Plant)
The iconic Monstera with its characteristic split leaves is becoming increasingly popular for water propagation.
How to grow: Look for a stem cutting that includes at least one aerial root (the nubs that grow from the stem). This aerial root is crucial for water rooting. Place the cutting in water, ensuring the aerial root is submerged. Bright, indirect light is best.
Maintenance: Change the water weekly. The aerial root will help the plant absorb nutrients and moisture.
9. Coleus
Coleus plants are grown for their incredibly vibrant and varied foliage colors. They are very easy to propagate in water.
How to grow: Take stem cuttings of about 4-6 inches. Remove the lower leaves and place the cuttings in a jar of water. They prefer bright light to maintain their colorful foliage.
Maintenance: Change the water every few days to keep it fresh.
Tips for Success When Growing Plants in Water
To ensure your water-grown plants thrive, keep these tips in mind:
- Use Clean Containers: Always start with clean jars or vases to prevent introducing bacteria.
- Use Filtered or Distilled Water: Tap water can contain chemicals like chlorine and fluoride that can be harmful to some plants. If you must use tap water, let it sit out for 24 hours to allow some of the chemicals to evaporate.
- Change Water Regularly: This is non-negotiable. Aim for every 1-2 weeks, or more often if the water looks cloudy.
- Provide Adequate Light: Most of these plants prefer bright, indirect light. Direct sunlight can scorch their leaves or heat the water too much.
- Monitor Water Levels: Evaporation will occur. Top up your containers with fresh water as needed.
- Be Patient: Root development takes time. Don't get discouraged if you don't see roots immediately.
- Fertilizing (Optional but Recommended): While plants can survive in water without fertilizer for a while, they will eventually need nutrients. You can add a very diluted liquid houseplant fertilizer to the water every few months once roots have established.
- Transitioning to Soil: If you decide to move your water-rooted plant to soil, wait until the roots are at least 1-2 inches long. Gradually introduce it to soil by planting it in a pot with moist soil and keeping it well-watered for the first few weeks.
Frequently Asked Questions (FAQ)
How often should I change the water for my water-grown plants?
You should aim to change the water every 1 to 2 weeks. This helps keep the water fresh, prevents bacterial growth, and ensures your plant has access to oxygen. If the water becomes cloudy or develops an odor, change it immediately.
Why are my plant's leaves turning yellow when grown in water?
Yellowing leaves can be caused by a few things. It might be a sign that the water needs changing, or the plant isn't getting enough light. Overcrowding in the container or a lack of nutrients (if it's been in water for a very long time without any added fertilizer) can also contribute. Ensure the leaf nodes are submerged, as this is where new roots will emerge.
Can I grow any indoor plant in water?
No, not all indoor plants can be successfully grown in water indefinitely. Plants that root easily from stem cuttings, like Pothos, Philodendrons, and Spider Plant babies, are ideal. Plants that require specific soil microorganisms or have very sensitive root systems are usually not good candidates for long-term water culture.
When should I consider potting my water-grown plant into soil?
You can typically pot a water-grown plant into soil once its roots are well-established, usually measuring at least 1 to 2 inches in length. Ensure there are multiple roots present before making the transition.
Growing plants in water is a rewarding and simple way to bring the beauty of nature indoors. With the right plant and a little attention, you can enjoy vibrant, healthy greenery with less worry and more style.
