Dividing indoor plants
Spring, when plants are poised for summer growth, is the best time for the
major maintenance like dividing. Divide and repot a plant once it has several
stems at the crown and fills its container. Cutting into the plant stimulates
the production of plant hormones that promote new growth, and as long as each
division has healthy roots, it will take off quickly.

Turn the plant and pot upside down, and supporting the soil with your open
hand, tap the bottom of the pot with your other hand, or tap the edge of the
pot against a hard surface to get the plant out of its container. Spread the
plant across a work surface, keeping as much potting mix as possible around
the roots. Look for clumps of stems approximately the size of the plants you
want. Tease the rooted clumps apart with your fingers, or divide them with
a knife or spade. Before repotting, pick out damaged scraps of stem

Set the pieces in pots a littlewider and deeper than the plants root mass.
Backfill with potting mix to 1/2 inch below the rim of the pot to allow a
water well, tamp the mix, water thoroughly, and set the plants in filtered
light for a few days.
