Growing plants in water usually require hydroponic techniques such as aeroponics, fogponics, ebb and flow or flood and drain sub-irrigation, deep-water culture, and so on. These systems have been extensively delved into on this website. However, there are plants that you can easily grow in a jar of water. Many plants including herbs, vegetables, and ornamental indoor plants can easily grow in water. Here are 25 indoor plants that grow in water, but before we get started, let us look at the things needed for a successful herb water garden.
Growing Herbs In Water Requires
The first thing you need when growing indoor plants that grow in water is water. Many herbs will simply grow as far as you place the plant herb cuttings in a plain jar of water. Tap water and chlorinated water may not be best for the plant. You can let the water sit overnight. This should cause the chemicals such as chlorine to dissipate. You can also collect rainwater. Spring water and well water are excellent for gardening. Not only is the water free of harmful chemicals, they also contain traces of helpful minerals such as calcium.
Containers For Water
The next thing you will need is a container. Glass jars such as mason jars will do perfectly. You can also use glass bottles. When it comes to containers, you can get creative. Many containers around the home will make excellent planters for indoor plants that grow in water. Colored plastic containers are excellent planters as they are colorful and opaque.
It is best if the container is opaque. This is because of two reasons. The roots of the plants prefer a dark zone. In addition, the presence of light in the growing medium (the water) encourages the growth of algae, which will compete with the plant for nutrients. Algae also call an unsightly sight. Amber colored bottles will also do well. You can wrap tape of paper around the bottle. This will present a dark zone for the plants’ roots to grow.
You can also go for narrow-mouthed containers are also advantageous. This is because the narrow-mouthed bottle will help keep the plant upright and support the plant cuttings. With that said, the bottle’s mouth cannot be too narrow as it will be a tight fit. The plant’s roots need to breathe. As such, the bottle/container’s mouth needs to be big enough to allow for adequate aeration.
For wide mouthed planters, you can cover the mouth of the container with wire netting. This will allow you to place the plant cuttings through the holes, as such adding support for the plant. Netting will also prevent mosquitoes from laying eggs on the water.
Plant cuttings such as soft cutting will easily take root in the water. As such, you will need not use rooting hormones.
- If you already have some herbs, growing in your indoor garden simply cut off half-foot sections of the growing tips and place them in containers filled with water. You can even use cuttings gotten from the supermarket. Wash the cutting in clean water, cut off the lower portion, and place them in the water-filled planter.
- You should ensure you remove all the lower leaves from the cuttings (as the leaves should not touch the water) and trim the low tips close to the plant nodes since that is where the roots will grow out from. If the leaves touch the water, the water will cause the leaves to rot. This will contaminate the water.
- Herbs that are woody such as rosemary will take longer to root. As such, tolerance is vital. While you wait for the roots to appear, you should change the water about once a week. Once the roots appear, you need not need to change the water at all.
- If the herb is having trouble rooting, you can acquire some rooting hormones. This will give the plant the boost it needs. You can also steep some branches of willow trees in warm water overnight. This is a natural rooting hormone recipe. You should then use that water as the growing medium. This will encourage the herb plant to root.
