How Much Water Does a Spider Plant Need?

The spider plant, also known as Chlorophytum comosum, is a popular houseplant due to its pretty, variegated leaves and easy-care requirements. However, one of the most common questions for new spider plant owners is how much water it needs. Let’s dive in and explore the watering needs of spider plants.

Watering Frequency

Generally speaking, spider plants prefer to be slightly on the dry side. Overwatering can lead to root rot, and underwatering can cause the leaves to wilt and turn brown. As a rule of thumb, watering once a week should suffice. However, the frequency ultimately depends on the size of the plant, the type of soil it’s in, and the surrounding environment(1).

Watering Amount

To determine how much water a spider plant needs per watering, you should consider the size of the pot, the soil type, as well as the amount of light and temperature it gets. As a general guide, water until the soil is damp but not excessively soaked. Watering until the water begins to pool at the bottom of the pot can lead to over-saturation and root rot(2).

Humidity and Temperature

Spider plants thrive in indoor environments with moderate temperatures and humidity levels. These conditions vary depending on where you live, the time of year, and the type of heating or cooling system used indoors. In general, spider plants need temperatures between 60-85℉ and humidity levels between 40-50% to thrive(3).

Watering Tips

Here are some tips to ensure your spider plant gets the proper amount of water:

Stick your finger into the soil and check the moisture level before watering.

Don’t let the plant sit in standing water as this can cause root rot.

Consider using a well-draining soil mix to prevent water from sitting in the roots.

Spider plants prefer slightly acidic soil, so consider using a slightly acidic fertilizer (4).

Conclusion

When it comes to watering your spider plant, moderation is key. Regularly check the moisture content of the soil, and adjust the watering frequency and amount accordingly. With proper watering, your spider plant will continue to grow and thrive for years to come.
