Fertilization
For best
growth and flowering, bird-of-paradise requires
fertilization. Slow-release fertilizers, such as sewage
sludge and bloodmeal, or an inorganic complete
fertilizer such as 12-4-8, can be used. Apply
slow-release fertilizers at a rate of three to five
pounds per 100 square feet of bed area and 12-4-8 at the
rate of one pound per 100 square feet of bed area.
Spread fertilizer around plants every three months
during the growing season. Addition of minor elements is
recommended.
At least
once a year, preferably during summer, remove dead
leaves and old flower stalks to prevent fungal organisms
from building up on dead tissue.
Cold
Hardiness
Although
the bird-of-paradise is a tropical plant, it will
tolerate temperatures as low as 24°F for a short time.
However, temperatures at freezing or below may damage
developing flower buds and flowers. The bird-of-paradise
can be grown in north Florida landscapes with
protection, but there is always a chance of losing a
season of blooms during a severe winter. You can ensure
blooms every year in north Florida by growing plants in
containers and moving them indoors when freezing
temperatures are expected.
