Hi there!
I've recently bought a beautiful dieffenbachia and repotted it a few days ago. However I noticed the tip of some of her leaves have started to turn brown and dry - could someone help me determine to what it is due ?

I've watered it when I repotted it and not since - the soil is now relatively dry and I'm hesitant about watering it right away in case the brown is due to overwatering...

The plant is close to a window that receives plenty of afternoon sun - but her leaves do not fall within the direct light. Does she lack light ?

Thanks so much!

Dieffenbachia leaves most commonly turn yellow due to overwatering, When you up-potted your Dieffenbachia into a large container you raised the water holding capacity. That may be more water than your Dieffenbachia can process. You have to check and find out if the soil is too wet or too dry in the root zone. Use your finger and stick it between the soil and the container and feel how wet or dry the soil is.

If it is very wet then remove any extra new soil on top of the old soil to allow for better evaporation. Let the soil dry well before watering again. It its too dry then give it enough water until you see a little bit come out the bottom and then stop. Let it dry well before watering again.
