If you’re a plant enthusiast, you may be curious about the Boston Fern’s ability to grow in water. While many indoor plants require soil for their growth, some can thrive in water alone, making them an excellent option for those who prefer low-maintenance plants. In this blog post, we’ll explore whether Boston Ferns can grow in water, how to propagate them using this method, and the tips to ensure their success.
Boston Fern Overview
The Boston fern is a popular houseplant, known for its lush foliage and graceful, arching fronds. These ferns are native to tropical regions, and they have adapted well to indoor environments, providing homeowners with a beautiful, low-maintenance addition to their plant collections.
Boston ferns thrive in warm, humid conditions and can be grown both indoors and outdoors. In the United States, they are best suited for outdoor growth in USDA zones 9-11, which offer the necessary levels of humidity and warmth. When grown outside, it is important to provide them with plenty of water and some protection from direct sunlight, as they prefer partial to full shade or filtered light (Study Nature).
Aside from soil, Boston ferns have the capability to grow in water, albeit at a slower growth rate than when planted in soil. With the right growing conditions and adequate nutrients, it is possible to maintain a healthy, thriving fern grown in water (Simplify Plants).
Growing Medium
Soil Vs. Water
Boston ferns can be grown successfully in both soil and water mediums, each offering its unique benefits and requirements. In soil-based environments, these plants typically thrive when given the right potting mix, moisture content, and drainage.
On the other hand, growing Boston ferns in water can be a visually appealing alternative to traditional soil-based methods. To grow ferns in water, it is helpful to select a section of the plant that has healthy roots and fronds, cleanse the roots under running water, and remove any damaged roots or potting medium (Balcony Garden Web).
Once the roots are prepared, placing the plant in a vase or glass bowl and adding stones or gravel to secure the roots in place is essential (Balcony Garden Web). The gravel also helps to prevent the stem from being submerged in the water. Regular maintenance to ensure proper water levels and nutrient supply is crucial for their health and growth in a water-based medium.
Hydroponic Methods
Boston ferns can be grown in water using several hydroponic techniques. These methods can be categorized into two types: Passive Hydroponics and Active Hydroponics.
Passive Hydroponics
Passive hydroponics is a low-maintenance approach for growing Boston ferns in water. In this method, the fern is placed in a container filled with a water-absorbing medium, such as perlite or coconut coir, that supports the plant’s roots and provides it with adequate moisture. The medium also prevents algae growth and root rot by allowing air to circulate around the roots. Fertilization in passive hydroponics is generally needed once a month during the summer with a weak, balanced liquid fertilizer.
Active Hydroponics
In contrast to passive hydroponics, active hydroponic systems use pumps and timers to deliver water and nutrients to the Boston fern’s roots. There are a variety of active hydroponic systems, such as nutrient film technique (NFT), aeroponics, and deep water culture (DWC).
- NFT: The nutrient film technique involves a shallow, constant flow of water containing nutrients that continually pass over the fern’s roots in a sloping trough.
- Aeroponics: This method suspends the fern’s roots in air and periodically mists them with a nutrient-rich water solution.
- DWC: Deep water culture submerges the Boston fern’s roots in a nutrient solution while providing oxygen through air stones.
Active hydroponic systems generally require more attention than passive hydroponics, as they involve monitoring and maintaining proper water and nutrient levels. However, these systems can result in faster growth and potentially healthier ferns when managed correctly.
Advantages of Water-based Growth
Growing Boston ferns in water offers several benefits compared to traditional soil-based growth methods. One primary advantage is the easier maintenance. It can be less challenging to manage the moisture levels required for healthy ferns, as the water medium allows for easier assessment of whether the plant has sufficient hydration (Love Planting).
Another benefit is the elimination of some common issues related to soil, such as fungal infections and pests. These problems can be more difficult to manage in soil-grown ferns, whereas water-grown ferns remain relatively protected from such issues as long as the water is changed regularly (Simplify Plants).
Lastly, water-based growth allows for better humidity control. As ferns thrive in a humid environment, the presence of water directly around the plant can help create and maintain the ideal conditions necessary for sustained healthy growth (Backyard Homestead HQ).
Challenges and Tips
When growing Boston ferns in water, gardeners may encounter some challenges. To ensure a healthy and thriving plant, pay close attention to nutrient management and humidity requirements.
Nutrient Management
Growing Boston ferns in water can result in a slower growth rate than when they are planted in soil. Therefore, it is crucial to provide the fern with adequate nutrients to support its development. Using a liquid fertilizer, specifically designed for aquatic plants, can help maintain the plant’s overall health. Change the water regularly and monitor the nutrient levels to prevent deficiencies or imbalances that may lead to poor growth or yellowing leaves.
Humidity Requirements
Like most ferns, Boston ferns prefer a humid environment. When grown in water, maintaining proper humidity levels can be a challenge, especially in dry or arid climates. To maintain the right amount of moisture, place the water container in a tray filled with water and pebbles, creating a humid microclimate around the plant. Additionally, you can use a humidifier or mist the leaves regularly to supplement the humidity in the air. Keep in mind that if the humidity levels drop too low, the fern’s fronds may turn brown and the plant’s overall health may suffer.
