Why is this happening?
Most of our house plants come from tropical regions so being exposed to lower temperatures or drafts might lead to a number of different symptoms that can be confused with other issues.
Symptoms
The whole plant is drooping or wilting
The plant starts to droop immediately after being relocated
It takes longer for the soil to dry between waterings, often requiring you to postpone watering.
In severe cases the leaves turn darker in color due to damaged tissue, and succulent leaves might get soft and mushy
What to do now
The first thing you need to do is to move your plant to a warmer and less drafty spot in order to prevent it from suffering any further stress
The sooner you move it, the better the chance that it will be restored to full health faster
Trim off any brown or severely damaged leaves since they won’t recover. This helps the plant focus energy on healthy growth.
If the cold exposure wasn’t too severe, the plant can still recover. Snooze the next watering if the soil hasn’t dried out properly, as overwatering during stress can worsen the situation.
In severe cases of cold exposure, the leaf tissue can turn soft and darker in color. As long as the stem or the centre of the plant is still healthy and living, it can recover in sheltered conditions again
Very succulent leaves should be removed if they're too damaged, as they might cause rot to the main stem otherwise
Common questions
What places should I avoid?
Most houseplants should be kept away from drafty doors, windows or air conditioner vents. Hot, dry drafts can be just as damaging, so don't place your houseplants above a radiator, close to a fireplace, or next to an appliance.
Could something else be causing these symptoms?
Damage from cold drafts often mimics symptoms of overwatering. Depending on the severity, problems may include slow plant growth and consistently moist soil that doesn't dry quickly. You might find yourself needing to delay watering and fertilizing tasks frequently. Identifying the issue can be challenging, as some plants show immediate damage, while others may decline gradually over time.
