For a Goldfish plant
(Nematanthus ‘Tropicana" formerly Hypocyrta) to bloom well in the warmer months this plant
needs a rest period in the cooler months. From November through March do not fertilize, keep temps on the cool side, and water just enough to keep the plant
from wilting, allowing the soil to become quite dry. Growth will be minimal and there will be no flowers
during this rest period.
In April, resume normal watering, keeping the soil moist, and fertilize monthly at half strength. It must be in a sunny window (south or west) to thrive. Expect flowers
from July-September. Prune long stems back to within a few inches of the soil to keep the plant
full and bushy.
