Before pruning philodendron plants, you’ll want to sterilize pruning tools. This simple but all important step takes seconds and helps prevent spread of disease causing bacteria that may affect the health of your philodendron. To sterile pruning tools, remove any mud or debris, then simply give the tools a quick dip in a solution of nine parts household bleach to one part water. Bleach can be corrosive, so rinse tools in clear water after they’re sterilized. Alternatively, wipe tools with regular rubbing alcohol, which is effective and not as corrosive as bleach.
Key Takeaways:
- Pruning a philodendron shouldn’t be done if it isn’t really necessary, and a good pruning job should never detract from the overall appearance of the plant.
- Before pruning philodendron plants, you’ll want to sterilize pruning tools.
- Cut off the longest, oldest stems, or any stems that are leggy or have a lot of yellowing or dead leaves.
“Although they don’t require a lot of pruning, occasionally cutting back philodendron plants keeps these beauties looking their tropical best and keeps them from becoming too large for their surroundings.”
