If you’re interested in growing your own arugula at home, you may have come across the concept of growing arugula in water. While this method may not be as common as traditional soil planting, it can be a fun and rewarding way to grow this peppery green. In this comprehensive guide, we’ll explore the process of growing arugula in water, from start to finish.
Choosing the Right Container
When it comes to growing arugula in water, the first step is to select a suitable container. Opt for a container that is at least a few inches deep and has drainage holes at the bottom. This will allow excess water to drain out, preventing root rot. You can use a wide variety of containers, such as plastic pots, glass jars, or even a shallow tray.
Preparing the Water
Before you start growing arugula in water, it’s essential to prepare the water properly. Fill your chosen container with filtered water or tap water that has been left out for 24 hours to allow any chemicals to dissipate. Make sure the water level is sufficient to cover the roots of the arugula plants once they are placed in the container.
Choosing the Right Arugula Variety
When selecting arugula seeds or seedlings for growing in water, opt for a variety that is well-suited to hydroponic or water-based growing. Look for varieties that are known for their quick growth and adaptability to different growing conditions. Rocket or wild arugula are popular choices for growing in water.
Planting the Arugula
Once you have your container and water ready, it’s time to plant the arugula. If you’re using seeds, sprinkle them evenly over the surface of the water and gently press them down. If you’re using seedlings, carefully place them in the water, ensuring that the roots are fully submerged. Keep the container in a sunny spot to encourage plant growth.
Providing Adequate Nutrients
While arugula can grow in water alone, providing additional nutrients can help promote healthy growth. Consider adding a hydroponic nutrient solution to the water to ensure that the plants receive essential nutrients such as nitrogen, phosphorus, and potassium. Follow the instructions on the nutrient solution packaging for best results.
Maintaining Proper Water Levels
One of the critical aspects of growing arugula in water is maintaining the right water levels. Check the water level regularly and top up as needed to ensure that the roots are always submerged. Avoid letting the water level drop too low, as this can cause the plants to wilt and affect their overall health.
Pruning and Harvesting
As your arugula plants grow, you may need to prune them to encourage bushier growth. Snip off any yellowing or damaged leaves, as well as any flowers that may start to form. When the arugula leaves reach a suitable size, you can start harvesting them by snipping them off at the base. Regular harvesting will encourage new growth.
Dealing with Bolting
One common issue that arugula growers face is bolting, where the plant quickly goes to flower. If this happens, don’t worry! Simply strip the stem of its leaves and use both the leaves and flowers in your salads. The stems can also be chopped and used to make a delicious arugula pesto.
Ensuring Proper Lighting
Arugula plants thrive in full sunlight, so it’s essential to provide them with adequate lighting. If you’re growing arugula indoors, place the container near a sunny window or under grow lights to ensure that the plants receive the light they need to photosynthesize and grow healthy.
Replacing the Water
Over time, the water in your container may become stagnant and depleted of nutrients. To maintain the health of your arugula plants, it’s essential to replace the water regularly. Every two weeks, empty the container, rinse it out thoroughly, and refill it with fresh water and nutrients to support plant growth.
