Most of us are aware of a number of vegetables that grow in water, but what about plants that grow in water? Do they exist, and if so, what are they? There are actually a large number of plants that take root in water, and, therefore don't necessarily need soil to grow. Of course eventually, all of these plants will need to be transplanted into soil, but in the meantime, they're happy with just some water and sun! The process of growing plants in water is called hydroponic farming.
But why would you grow plants in water, you ask? For most gardeners, it's a great way to start plants for free! You may have a neighbor or friend that has an amazing plant, and, from that cutting, you can regrow the plant in water! Growing plants from cuttings is easy, but even easier so when they can take root in water! Moreso, plants that grow in water are easy to care for, meaning they're great for the beginner gardener as well as a great project to do with kids! Keep reading to learn more about plants that grow in water and how to make sure they take root!
Plants That Grow in Water
There are a few reasons why growing plants in water is great! For one, it's super simple and doesn't require anything else but a glass and some water! Secondly, plants grown in water have no pests or soil borne diseases to deal with, as long as you change the water frequently.
Don't forget though, that once your plants have developed a full and healthy root system, they must be transferred to a soil medium such as a pot or directly outdoors depending on the plant and the climate. This may take anywhere from 2 to 6 weeks. Some plants will also grow indoor with no issue, while others may benefit more from the outdoors.
There are a wide variety of herbs that easily grow in water such as basil, sage, mint, and lemon verbena. Tropical and sub-tropical houseplants also grow very well when propagated in water, and some of the easiest plants that grow in water are the following:
Fiddle Leaf Fig
Polka Dot Plant
But of course the number of water grown plants is quite lengthy, but we've shown you the best and easiest to grow in water! Simply submerge the roots of the plant in a jar of water, place it near a warm and sunny spot, and watch it grow.
Growing Houseplants in Water
For most of the above plants, all you need is a vase or a mason jar and some tap water to start the process. Over the course of a few days, or a few weeks, depending on the plant, they will take root. You can then just leave them in their medium or transplant them to a pot.
What's great about plants that grow in water is that you don't need to have a green thumb to do this! Most of these plants are very low maintenance, and therefore don't require a lot of know-how or care.
Whether you're growing indoor plants or a tropical plant, be sure to follow the care guidelines for each plant. A tropical plant for example, will require plenty of sun and fairly moist soil. So be sure to place your tropical plant in south-side facing window. An indoor plant may not need much sun at all, but rather just humidity.
Plants that are submerged in water will also need their water changed every few days. This is to ensure that the water is clean, and the roots can grow uninhibited. In fact, you can even grow some plant starts in water provided they are water loving plants.
If you want your water plants to grow even quicker and bigger, you can also give them some nutrition. A small amount of liquid fertilizer is all your water plant needs to really thrive. You can add a fertilizer solution every four to six weeks. To prevent algae formation, you should use a dark jar or container. If algae does become an issue, simply change out the water and rinse the plant's roots.
