A lot of people love spider plants, and they’re easy to take care of. Their graceful cascading foliage makes them perfect for hanging baskets. However even easy care plants can sometimes develop problems. Don’t worry if your spider plant’s leaves are turning yellow. This often happens for a number of reasons, and there are things you can do to fix it.
What Causes Yellow Leaves on Spider Plants?
Spider plant leaves can turn yellow if they are moved to a new spot, get a disease, or are damaged by pests. There are a few main reasons why spider plants’ leaves turn yellow.
Environmental Issues
- Old, compacted soil that lacks nutrients
- Buildup of fertilizer salts from overfertilizing
- Too much or too little light
- Shock from being moved to a new spot
- Minerals in tap water
Yellow leaves caused by environmental issues will often affect the oldest leaves first. Make sure your plant has loose, well-draining soil and only fertilize monthly. Leach the soil after fertilizing to prevent salt buildup. Move the plant gradually to a new location over a week or two to prevent shock. Use distilled or rain water if your tap water has a high mineral content.
Disease
- Root rot from overwatering
- Rust fungus
Root rot and other fungal diseases can happen if the soil stays wet for too long. This can cause the leaves to turn yellow and drop. Water only when the soil on top is dry, and make sure the pot has good drainage. If root rot is present, cut off any roots that are soft or rotting and repot the plant in new soil. Rust fungus can also cause yellow spotting on the leaves.
Pests
- Mealybugs
- Aphids
- Scale
- Whiteflies
- Spider mites
Feeding bugs like mealybugs and aphids take sap from the leaves, which turns them yellow. To get rid of pests, rinse the leaves with water and then use insecticidal soap or neem oil. Keep the plant isolated until the infestation clears.
Other Causes
- Nutrient deficiencies
- Shock from repotting or dividing
- Natural aging of lower leaves
Nutrient deficiencies can sometimes cause yellowing if fertilizer isn’t applied regularly. Repotting or dividing the plant can also shock it initially and cause some leaves to yellow while it recovers. Lower leaves naturally age and turn yellow over time as well. As long as it’s just a few older leaves, this is nothing to worry about.
How to Fix and Prevent Yellow Leaves on Spider Plants
Now that you know why your spider plant has yellow leaves, here are some tips to fix and prevent the problem:
-
Repot in fresh soil annually or when compacted. Choose a pot with drainage holes.
-
Water only when the top inch of soil is dry. Don’t let the plant sit in water.
-
Fertilize monthly in the spring and summer with a balanced liquid fertilizer.
-
Leach the soil with water after fertilizing to prevent salt buildup.
-
Check for pests like spider mites under the leaves. Rinse and use insecticidal soap if found.
-
Prune off any soft, rotten roots and repot in fresh soil if root rot is present.
-
Move the plant gradually to a new spot over 7-10 days to prevent shock.
-
Rinse dust off the leaves periodically and provide good airflow.
-
Don’t rely on tap water, use rainwater or distilled water if possible.
-
Repotting and dividing may cause some yellowing at first. This is temporary.
-
Remove spent lower leaves as needed to keep the plant looking tidy.
With a little detective work and appropriate care, yellow leaves on spider plants can be fixed. Just be sure not to overwater, let salts build up, or expose it to drastic changes. With the proper environment and routine care, your spider plant should thrive for many years with gorgeous green leaves cascading gracefully.
Frequently Asked Questions About Spider Plants With Yellow Leaves
If this is your first time dealing with yellow leaves on your spider plant, you probably still have some questions. Here are answers to some of the most common questions about caring for spider plants and treating yellow leaves.
How much light do spider plants need?
Spider plants are relatively flexible when it comes to light needs. They can tolerate low to moderate indirect light. But very bright, direct light can scorch the leaves. Find a spot near an east or west window where the plant gets bright indirect light.
How often should you water spider plants?
Spider plants prefer slightly dry soil. Only water when the top inch of soil is dry to the touch. Water thoroughly until it drains out the bottom, then dump out any excess water in the saucer. Allow the soil to dry out some before watering again.
What kind of soil is best for spider plants?
A well-draining potting mix formulated for houseplants is ideal. You can also make your own mix with equal parts peat moss, perlite, and compost. Soilless potting mixes help prevent overwatering.
When should you fertilize spider plants?
Fertilize spider plants monthly in the spring and summer with a balanced liquid fertilizer diluted to half strength. You can fertilize less often in fall and winter, such as every 6-8 weeks. Stop fertilizing if the plant stops actively growing.
How do you prune spider plant leaves?
Use clean scissors or shears to cut off spent leaves near the base of the plant. Pruning keeps the plant looking tidy and encourages new growth. You can also snip off browned tips or damaged sections of leaves.
How do you propagate new spider plants?
Wait until the plant produces baby spiderettes on flowering stalks. Use sterilized scissors to cut below the roots of the spiderette when it’s a few inches tall. Place it in a small pot of well-draining soil. Keep it moist and out of direct sun until rooted.
Enjoying the Graceful Beauty of Spider Plants
When properly cared for, spider plants are easy to grow houseplants that provide an airy, graceful look. Their arching leaves and trailing spiderettes bring visual interest without taking up much space. Just be attentive to your plant’s needs, especially when it comes to watering. Address any issues promptly, and your spider plant should continue thriving for many years. The handsome variegated varieties add extra pop of color as well. Spider plants are definitely a must-have for any houseplant collection!
