They are super easy to keep happy and advertised often as “unkillable”.

So, if your snake plant isn’t doing well, you might be a little puzzled.

A snake plant was one of my first plants – it had a tag on it that said IRON PLANT HARD TO KILL – and I killed it within the month.

Even easy plants can have problems and need some troubleshooting.

So, today we are going to chat about yellowing leaves on a snake plant and what to do about them!

Why is my snake plant turning yellow?

Here are a few common reasons that you might get snake plant yellowing leaves.

  • Overwatering
  • Low humidity
  • Inconsistant watering
  • Insufficient light
  • Root bound plant
  • Bacterial Leaf Spot
  • Pests
  • Old age

Overwatering

Overwatering is the #1 cause of yellowing leaves on most indoor house plants. In general, plants don’t like to sit in excess water. Pooling water can lead to root rot which will kill your plant.

Keep in mind that snake plants really don’t need much water. They can go quite a while between waterings.

If you suspect overwatering, stick your finger about 2 inches into the soil. Does it feel wet? Don’t water again until it dries out.

If your plant is way over watered, take it out of the pot. Dump out any excess water and wet soil and re-pot with fresh potting mix.

Be sure that your pot has drainage holes to prevent excess water from pooling in the future.

Low humidity

I find this to be MUCH less frequent than over watering, but low humidity can cause leaf drop. Usually the leaves will get brown, crispy spots on them (often on the tips). Then, the leaves might turn yellow.

These symptoms indicate that the plant is drying out. If it’s being watered well, misting the leaves can help to improve humidity in the air.

Inconsistant watering

In my experience, snake plants are NOT very picky. However, some claim that they like to be on a watering schedule.

Going from bone dry to soaking wet at random intervals could stress out your plant and lead to yellowing leaves.

If in doubt, establish a regular watering schedule and try to stick to it.

Insufficient light

Snake plants don’t need hardly any light – they do fine far away from windows. However, they still need SOME light.

If your plant isn’t getting enough light, the leaves will start to turn yellow and drop. This will especially happen to older leaves towards the base of the plant.

The cure to this is to move your plant into brighter light. It will be much happier.

Root Bound Plant

It is possible that your plant has become root bound. Basically, the roots are too big for the pot.

Pull it out of the pot and see! If it’s been there a while – this is a real possibility.

If the roots are tightly packed or even poking out the drainage hole – time for a bigger pot. Add fresh potting soil while you are at it for a happier plant!

Bacterial Leaf Spot

Soft, brown, mushy spots on a leaf are called Bacterial Leaf Spots. This come from water sitting on the leaves and rotting them.

Remove all effected leaves and avoid getting the leaves wet when you water it!

Over Fertilization

Snake plants don’t need to be fertilized to thrive. If you fertilize them a lot of too often, they can get yellow and mushy.

Pests

Spider mites, scale, and mealy bugs can get on the underside of leaves and suck the nutrients out of your plant.

If you suspect pests, isolate your plant to help prevent it from spreading to other plants.

Old age

As plants get older, it is natural for some of the older leaves to yellow and fall off, making room for new growth. Keeping a leaf green takes energy, and some plants decide to allocate that energy to new plants.

If this is the case, you will have yellowing of older leaves – near the base of the plant – only, and not new growth.
