Everything You Need to Know About Growing Spider Plants in Water

The spider plant is the perfect choice if you’re looking for an aquatic houseplant that doesn’t require much maintenance. These plants are sturdy and easy to care for, meaning you can easily keep them in water without worrying about them.


Spider plants are an excellent choice for fish aquariums as they don’t contain toxins that can harm the fish. Water requirements for spider plants are minimal. They also do well in aquariums if the water is clear, soft, and between 70 to 90 degrees Fahrenheit.

Place the plant in a container with some moisture and let it soak up the liquid. Do not overwater spider plants – keeping the soil moist is more than enough. Spider plants can be grown indoors or outdoors in any climate zone.

Keep them moist but never allow the roots to get root bound. Overwatering can cause the plant to become soggy and sickly looking. Please give them a good shake every few days, so their water evenly distributes throughout their root system.

Make sure to give them regular water changes and fertilizer to help them grow roots and foliage quickly! Spider plants need plenty of light and humidity to thrive, so ensure the tank has enough.


Spider plants don’t require a lot of light – they can tolerate some low-light conditions. However, they may not do well, and the leaves might start wilting. They do best in bright, sunny rooms but can also live in moderately lit areas.

Water the plant regularly – like you would water a cactus – and fertilize it with a balanced fertilizer every couple of weeks during the growing season and sparingly in winter. If you are not happy with the size or shape of your spider plant, cut it back to new stem growth in early spring!


Spider plants need warm water to thrive; the ideal temperature is around 70 to 90 degrees Fahrenheit. Spider plants are great for people who live in cold climates as they do well with slightly acidic water. They also prefer warm (but not hot) water and grow best in moist soil but not too wet or dry.

Keep the plant out of direct sunlight, as it will burn quickly. Feed the plant weekly with a balanced fertilizer and water. Spider plants are very low-maintenance. Just make sure you keep them adequately watered and fertilized!


Provide spider plants with the right environment and nutrients. Spider plants thrive in water but require a lot of fertilizer – they should be given once a month with a particular plant fertilizer specifically designed for aquariums. Make sure you use a high-quality fertilizer specifically for this plant – colloidal phosphate or fish emulsion are both excellent choices.

You can water them directly with fertilizer or add them to the water before watering them. Make sure to shake the bottle well before each use so that the ingredients are evenly dispersed. As spider plants aren’t aggressive by nature, please keep them in small groups or tanks as they do not like crowded.

Be Aware of Pesticides

If you do decide to use a pesticide, dilute it first. Spider plants are great additions to aquatic settings because of their attractive foliage and slender stems, but remember that spiders plant can be dangerous if it has pesticide!

Spider plants are a popular houseplant, but be aware that they can be toxic to fish if you place them in water with fish. Always read the label before using any pesticides – even if you’re using them indoors – and make sure they’re safe for your fish.

Common Spider Plant Problems in Aquariums

Spider plants are famous for aquariums but can be a problem for fish if the sap is spilled. The sap is a sticky fluid that the plant produces to capture insects and other small animals. It can cause algae to form, which is distasteful to fish and can increase the risk of disease. If problems persist, consider getting another type of plant for your aquarium.
