If yellow leaves develop on the philodendron, the gardener needs to take action. Leaf discoloration usually indicates deficits in care. You can read about the most common cause with tips for solving the problem here.
Waterlogging can be the reason why philodendron leaves turn yellow
Cause #1 of yellow leaves: waterlogging
A tree friend needs a constantly slightly moist substrate so that it thrives magnificently. This does not mean that a philodendron should be watered often and abundantly. In fact, the water consumption is low. This harbors the potential for misunderstandings, so that waterlogging develops, whereupon the leaves turn yellow. How to act correctly now:
- Unpot the wet root ball and remove all substrate
- Cut off rotten roots with a sharp, sanitized tool
- Potting in dry, acidic substrate over potsherd drainage
After repotting, give your philodendron a week to regenerate and do not water. In the period that follows, modify the water supply so that you only water when the substrate surface has dried noticeably.
