The Art of Growing Plants in Water

Growing plants in water offers a convenient alternative to traditional soil-based cultivation. Not only does it alleviate concerns about soil-borne diseases and fungi, but it also simplifies the watering process. In fact, once you transition to water-based gardening, you’ll never have to worry about watering your plants again!

To ensure successful water cultivation, there are two key factors to consider: providing adequate oxygen and essential nutrients to your plant roots. This article will guide you through the necessary steps to optimize these elements and achieve thriving water-grown plants.

Nourishing Your water garden

Adding nutrients to the water

When it comes to water gardening, proper fertilization becomes a vital component. Unlike soil mixes, water lacks natural nutrient traces, making it necessary to incorporate a regular fertilizing schedule. To get started, add a few drops of liquid fertilizer to the water, adjusting the amount according to the container’s volume, as stated in the manufacturer’s instructions. Treat fertilizing your water-grown plants as you would with traditional potted plants, ensuring you only fertilize during spring and summer.

Oxygenation for Optimal Growth

Oxygenating the water

To maintain optimal oxygen levels for your plant roots, it is crucial to change the water in your vase or container regularly. Roots rely on oxygen for their metabolic functions, including nutrient absorption and growth. While plants growing in soil can access oxygen through the surrounding environment, water-grown plants depend on the water itself for oxygen. However, as roots consume oxygen and release carbon dioxide, water can become depleted of necessary oxygen.

To prevent this, replace the water entirely every two weeks. Not only does this ensure a fresh supply of oxygen for your plants, but it also prevents the accumulation of harmful bacteria that thrive in stagnant water. When refilling your vase, consider using a high-pressure burst from the tap or a tap that dispenses bubbled water, as colder water holds oxygen better. Alternatively, you can use an air pump, similar to those found in fish aquariums, to maintain oxygen levels without the need for frequent water changes.

Keeping Algae at Bay

Frequent water changes also help prevent the build-up of algae and bacteria, particularly in clear glass containers that allow sunlight to nurture their growth. If you notice excessive algae, remove it and relocate the container to an area with less direct sunlight. For plants that require abundant sunlight, opt for a dark-tinted glass or ceramic container to mitigate algae-related issues.
