Common Causes of Rotting Pothos Cuttings
Some of the most common causes of rotting cuttings include:
- Lack of oxygen
- Leaves in the water
- Fungal or bacterial infections
- Exposure to cold temperatures
Lack of oxygen
Plants absorb oxygen as well as other nutrients through their roots. As your plant sits in water, it releases carbon dioxide and absorbs all of the oxygen.
If you don’t change the water, it can run out of oxygen. This is the #1 cause of water propagation stem rot & root rot.
Luckily the answer is easy – change the water!
Leaves in the water
Always remove any leaves that will fall into the water on your pothos. Wet leaves will almost always rot.
Fungal or bacterial infections
Plant cuttings are as susceptible to infections as any other plants. Examine them – and the plants around them – for signs of infections. This usually looks like yellow, tan, brown/reddish or black spots on leaves.
Exposure to cold temperatures
Wild fluctuations in temperatures – especially cold – can kill pothos cutting and lead to them getting mushy. They might not actually be rotten, but the end effect is the same!
How to Prevent Rotting Pothos Cuttings
Providing proper air circulation
The easiest thing to help prevent water propagation root rot is to change the water regularly – about once a week. This ensures that there is plenty of fresh oxygen in the water and helps it from getting foggy or smelly, too.
Treating infections with fungicides or pruning affected areas
Rotten plant pieces can be dipped in 3% hydrogen peroxide. I have personally not tried this, though it is a common suggestions.
I highly recommend pruning any rotten pieces as soon as you notice them to try to avoid the rot spreading.
Keeping cuttings away from cold drafts
Keep your cuttings in a place with consistent temperatures and no cold or hot drafts. Watch out for vents!
How to Fix Root Rot
If your pothos cutting is already rotting, you have two options.
One, give up and throw it away.
Or, use sterile scissors to carefully remove any rotten stem or roots. This is anything black or mushy. It will not come back to life.
Dump the water, clean the container, and refill it with fresh water.
Place the container in bright, indirect light and monitor it to see if it does better moving forward.
Tips for Healthy Pothos Cuttings
Here are some tips to ensure your pothos cuttings stay healthy:
- Always use clean and sharp tools for cutting
- Only take cuttings from healthy parent plants
- Place cuttings in a warm and humid environment – covering loosely with a clear plastic bag can help to create a “greenhouse effect”
Avoid these Common propagation mistakes
- taking cuttings from an unhealthy plant – withered leaves won’t suddenly come to life as a cutting
- using dirty tools to take cuttings – this can spread diseases
- using blunt tools – clean cuts heal and root easier in general
- forgetting to replace the water – this leads to a lack of oxygen and stem and root rot
- cutting in the wrong place – you need a node for pothos water propagation
