Soil isn’t the only way to grow a lush, thriving garden. Hydroponic gardening, the practice of growing plants in water, is an efficient and innovative approach for creating a green oasis at home. With minimal space and effort, you can grow a wide variety of herbs, vegetables, and ornamental plants. Here’s a comprehensive guide to 25 options you can cultivate in water.
Herbs
- Basil: Place 4-inch cuttings in a water container. Refresh the water regularly to encourage growth.
- Mint: Hardy and fast-growing, mint thrives when propagated from cuttings in water.
- Oregano: Start with stem cuttings in water; roots will appear within days.
- Sage: Spring cuttings grow best in water with ample light and ventilation.
- Stevia: Known for its sweet leaves, stevia loves indirect light and water propagation.
- Thyme: Start from cuttings, ensuring they receive abundant light for root development.
- Lemongrass: Submerge the root end in water, and it will sprout new shoots. Warm environments work best.
- Cilantro: Place stems in a glass of water, changing it every few days for fresh leaves.
Vegetables
- Lettuce: Regrow from the base by placing it in shallow water; harvest young leaves.
- Celery: Similarly, the base can regenerate stalks when kept in water.
- Green Onions: Keep the white base submerged for a constant supply of green shoots.
- Garlic Chives: Sprouted garlic cloves in water yield flavorful chives for cooking.
- Bok Choy: Submerge the base in water to grow fresh leaves.
- Carrots: Use carrot tops to grow edible greens (not new roots).
- Peppers: Start seeds in water; transfer to soil once sprouted for better yield.
Houseplants
- Pothos: A popular indoor plant, pothos roots easily when cut below a node.
- Philodendron: Similar to pothos, it thrives in water when propagated from cuttings.
- Spider Plant: Place baby plantlets in water until roots develop, then pot them.
- Peace Lily: Elegant and easy to maintain, peace lilies can grow directly in a water vase.
- Lucky Bamboo: Known for its resilience, change water biweekly for optimal health.
- African Violets: Grow these from leaf cuttings in water; transplant to soil once rooted.
- English Ivy: Cut a section, submerge it in water, and watch roots develop.
- Coleus: This colorful plant roots quickly in water and can later be planted in soil.
- Begonia: Use a single leaf for propagation in water; it thrives with minimal effort.
- Impatiens: Bright and cheerful, impatiens are easy to grow from water cuttings.
Tips for Successful Hydroponic Gardening
- Container Selection: Use opaque containers to minimize algae growth.
- Water Maintenance: Change the water regularly to prevent rot and replenish oxygen.
- Fertilization: Add liquid hydroponic fertilizer to provide essential nutrients.
- Lighting: Ensure plants receive ample light, either naturally or via grow lights.
- Patience: Some plants may take longer than others to root—be persistent.
