I have a 25 yr old, what I believe to be a Philodendron bipinnatifidum. It is overgrown with roots in a 16 inch pot. It stays indoors in a bathroom with a skylight over the winter months then brought outside during late spring to mid fall temperature permitting. There are 4 live plants with 1 dead entangled stalk in the pot. I am looking to separate the 4 live plants and repot to smaller pots. Can this be done safely without killing this plant and if so what would be the procedure?
Yes, you can divide a Fiddle leaf Philodendron.
1 week before dividing, water the plant throughly. Water should drain from the plant to ensure all of the pot and roots are watered.
Then do not water until you have divided the plant.
With the pot on it's side, slide the plant from it's pot, taking care not to damage the leaves.
Inspect the roots to look for natural divisions.
Using a sharp and clean knife, cut down from the crown to the bottom of the root ball. Each division should have a part of the crown and roots.
Place in appropriate sized pots with good quality soil and drainage.
Water throughly and keep in a filtered light location to help with plant shock.
