If your usually lively spider plant isn’t growing as it should then don’t worry. You’re not alone.
Spider plants (Chlorophytum comosum) are generally easygoing but they do have their quirks. It’s not always plain sailing looking after them and things can and do go wrong.
So if yours has started to struggle the following guide will take you through the main reasons as well as how to get it back on track.
Common Causes of Stunted Growth
1. Light Problems: Too Much or Too Little
Spider plants thrive in bright, indirect light. Too little light will slow their growth while too much direct sun can scorch the leaves, leaving them crispy and brown.
If your spider plant has been sitting in a dim corner that’s definitely a no-non. In fact it’s time to move it right now! Get it closer to a bright window – north or east-facing windows are ideal as they provide lots of indirect light without harsh midday rays.
On the other hand if your plant’s leaves are yellowing or browning then it could be getting too much direct sunlight. In this case you’ll want to move it farther from the window or use a sheer curtain to diffuse the light.
Rotating your plant on a regular basis can also help make sure even growth all around. The lighting balance is really important, arguably the most important aspect of spider plant growth, especially during the winter months when natural light decreases. So focus on this first if your spider plant isn’t doing well.
2. Watering Mistakes
Spider plants like their soil to stay moist but not soggy. Too much water can lead to root rot and too little will leave it parched and unable to grow.
So the solution: water your spider plant when the top inch of soil feels dry to the touch. On top of that make sure the pot has proper drainage to avoid waterlogging.
If you notice any browning leaf tips it could be a sign that the water you’re using has too much fluoride or chlorine. Switching to filtered, distilled or rainwater can prevent this issue.
And an extra tip: give your spider plant a good soak when watering, making sure the water runs out of the drainage holes. Empty the saucer beneath the pot to avoid the plant sitting in standing water.
3. Temperature and Humidity
As spider plants like a tropical climate it means they want warmth and moderate humidity. So if you can keep your plant in a spot where the temperature stays between 55°F and 80°F (13°C to 27°C).
If the temperature dips below 50°F (10°C) your spider plant will slow its growth and may even develop mushy leaves. Drafts from air conditioning or heaters can also cause stress so avoid placing the plant near vents.
Humidity is another important factor especially if you live in a dry climate. If you see any leaves curling or wilting then it could be a sign your spider plant needs more humidity.
Putting a pebble tray with water beneath the plant or grouping it with other plants is a good and simple way to boost the humidity around it. You might even consider using a small room humidifier during the dry winter months.
Solutions for Common Spider Plant Problems
1. Root Bound Plant
Spider plants grow fast and before you know it they have outgrow their pot. So you’ve got to keep on top of them.
If you see roots poking out of the drainage holes or coiling around the top of the soil there’s a good chance your spider plant is root bound. This will test it its ability to take up water and nutrients which in turn will stunt it’s growth.
Repotting every two to three years can help. Choose a pot that’s only slightly larger than the current one. Going too big might lead to overwatering issues as the larger pot will retain more moisture than the plant can handle.
2. Poor Soil
Well draining soil is the spider plants favorite. If the soil is compacted it can suffocate the roots, which again leads to stunted growth. A mix of regular potting soil with added perlite or pumice works well. This improves drainage and aeration so the roots have room to breathe.
Advanced Tips for Encouraging Spider Plant Growth
1. Fertilize Sparingly
Spider plants don’t need much fertilizer. Over-fertilizing can cause a buildup of salts in the soil which is a cause of brown tips on the leaves.
Feed your spider plant with a balanced, water-soluble fertilizer once a month during the growing season (spring and summer), but hold off during fall and winter when the plant isn’t actively growing.
2. Pruning for Health
If your spider plant is getting too gangly, or if you see brown, dry tips, don’t be afraid to prune. Use sterilized scissors to trim off dead or damaged leaves at the base. Removing spider plant “pups” (the small offshoots) can also help redirect the plant’s energy into growing healthier, fuller leaves.
3. Addressing Pests
Though spider plants are pretty resilient to pests, they can occasionally fall victim to things like spider mites or aphids. If you notice sticky residue on the leaves or tiny insects it’s time to act.
A good spray with insecticidal soap or neem oil should do the trick. Regularly inspect your plant, especially if it lives outside during the summer.
Troubleshooting Specific Issues
Problem | Cause | Solution |
---|---|---|
Leaves turning brown | Fluoride or chlorine in tap water | Use distilled or rainwater |
Yellowing leaves | Too much direct sunlight | Move to a spot with indirect light |
Limp, droopy leaves | Under or overwatering | Adjust watering schedule |
Stunted growth | Pot-bound roots or poor soil quality | Repot and use well-draining soil |
Root rot | Overwatering or poor drainage | Let soil dry out, repot if necessary |
Final Thoughts
Spider plants are forgiving, which is part of the reason they’re so popular. But that doesn’t mean you can ignore them completely and they do require some basic care to really thrive.
If you’ve noticed your plant isn’t growing like it used to, take a step back and assess its light, water and soil conditions. Making what might seem like small adjustments – like moving it to a better-lit spot or repotting it with fresh soil – can often make a big difference.
You’ve just got to have patience and be willing to watch and wait. Keep an eye on your spider plant’s environment and health and you’ll likely see new growth sprouting in no time.
