Grow lipstick plant in a medium to bright spot. The
more light it gets, the better lipstick plant will bloom. If you have a
lipstick plant that won't produce flowers, try moving it to a brighter
spot.
Water lipstick plant enough to keep the soil moist, but not wet or
saturated for extended periods. Don't let lipstick plant wilt, but also
take care not to overwater it. If this houseplant stays too wet, it will
suffer from root rot.
Fertilize lipstick plant monthly in spring and summer to help it produce
lots of flowers. Use any general-purpose houseplant fertilizer. Just be
sure to follow the instructions on the product's packaging.
