Araucaria
heterophylla-
Norfolk Island pine

This tropical evergreen tree is well loved
for its dark green needles and completely symmetrical form. It can easily
be grown indoors as a houseplant growing up to 20' tall with appropriate
cultural care.
CULTURAL REQUIREMENTS
Light: Araucaria needs bright light
preferably eastern or western exposure and will retain best foliage color
with one to two hours of sunlight per day.
Watering: When soil feels slightly
dry to the touch, water your Norfolk Island Pine thoroughly being sure
that the water goes into a saucer. After 15 minutes discard all excess
water that the tree has not taken back up.
Temperature: The Norfolk Island
Pine grows best in temperatures between 60 and 72º F during the day
and 50º to 65º F at night.
Humidity: A relative humidity above
50% is preferred to successfully grow Norfolk pine indoors. Provide additional
humidity by misting twice daily. An excellent method of providing extra
moisture is to stand plants on shallow trays filled with moistened pebbles,
and/or use a humidifier.
Feeding: Feed Araucaria only during
the growing season (March through September) with a dilute, standard, liquid
fertilizer once every two weeks.
Transplanting: When roots begin
to grow out of the bottom of the pot, transplant into the next largest
size pot (always use the deepest pot with this tree). Use a soil mixture
of equal parts sterilized houseplant potting soil. peat moss and sand/or
perlite, with a tablespoon of bone meal.
Propagation: Only a tip cutting
from the very top of old plants will develop into a completely symmetrical
specimen so the easiest method to grow Araucaria is from seed.
Maintenance: To keep its growth
most symmetrical, turn it slightly every week. Supply extra humidity to
avoid the common problem when needles turn brown and dry up by.
Special Note: Give the Norfolk Island
pine as much natural light as possible in the winter months to assure good
symmetrical development.
