can be found growing in all corners of the earth.
Cool growing orchids can take
temperatures down to 50 degrees. These include varieties
of Cymbidium (some can survive at 40 degrees),
Cypripedium, Draculas, Masdevillias and others in the
Pleurothallis alliance, some Laelias like Laelia anceps,
Zygopetalum, and reed stem Epidendrum. Some can be grown
outdoors where the winters are mild.
Mid range or temperate
growing orchids can take temperatures down to 55-60
degrees. These include Odontoglossum, Brassavola, some
Dendrobiums, Epidendrum, Laelia, Lycaste, Paphiopedilum,
Warm growing orchids can
take temperatures down to 65-70 degrees and like daytime
temperatures around 60-90 degrees. These include
Phaleonopsis, Dendrobium, Cattleya, Oncidium, Vanda,
Ascosendra, Brassia, Renthanopsis, and Doritis.
Bright filtered indirect light 1000 foot candles with no
direct sun.Keep warm 70 to 85 degrees with a night time
low of 62. Water about once a week and let drain
completely out of weep holes at bottom of pot (do this
with all orchids); do not allow pot to sit in standing
water. Water in the early morning and keep water away
from the growth crown of the plant. Use a straw to blow
out any water that gets in the crown. This helps to
prevent crown rot. When plant is done flowering, cut
flower stem to second or third internode to encourage a
second flowering or remove stem at one inch from base to
allow for a new flower stem to develop. Phaleonopsis
orchids bloom about once a year for 4 to 6 weeks.
Bright light with no direct sun 1500 to 2000
foot-candles. Keep warm 70 to 85 degrees with a night
time low of 60 degrees. Water once a week and let drain
completely. When transporting Cattleya type orchids,
protect flowers from bruising with shredded waxed paper
on the leaves and secure well. Bloom about once a year;
the flowers last 2 to 6 weeks depending on variety and
thickness or texture of the bloom.
Bright light with no direct sun 2000 to 3000 foot
candles. Keep warm at 75 to 85 degrees with a night time
low of 60 degrees. Water once a week and let drain
completely. Bloom about once a year. Plants can become
top heavy, so placing plastic grow container into a
terracotta pot can help to solve this problem as well as
placing crushed granite rock into potting mix. Blooms
about once a year and flowers last 4 to 6 weeks.
Bright light with no direct sun 1500 to 2000 foot
candles. Generally Oncidiums like 70 to 85 degrees
daytime and can go down to 55 degrees at night. Watch for
bacterial black speckling on leaves witch may occur in
warm growing conditions. Water once a week allowing to
drain completely (let plant dry out between waterings).
Blooms last about 4 weeks.
Bright light with no direct sun 2000 to 3000 foot
candles. Keep warm 75 to 85 degrees and nighttime low of
62. Water once a week and let drain completely. Try to
keep water out of leaf at stem to help prevent stem rot.
Bloom about once a year and flowers can last 8 weeks on
Bright light with no direct sun 900 foot candles. Keep
warm 75 to 85 degrees with nighttime low 55 to 60. Water
once a week and let drain completely ( some standing
water can be OK). Blooms about once a year generally
mottled leaf varieties bloom in the summer.
Bright light with no direct sun 1200 to 1500 foot
candles. Keep warm 70 to 75 degrees and nighttime lows
55. Water once a week and let drain completely. Crinkled
leaves are a sign of insufficient water which might come
from watering or root problems. Transplant and change
potting mix annually.
Bright to medium light grow outdoors with an eastern facing exposure so
the plants can receive direct sunlight in the morning hours when the light
intensity is lower and cooler. Water once to twice weekly depending on

fir bark 1/8th to1/4 inch. We are happy to take care of repotting at your

You can grow orchids in several types of media. We
suggest douglas fir bark that is sterilized. Fine bark
1/8 to 1/4 inch is suitable for most Oncidiums,
Miltonias, Paphiopedilums, Phrags, and Cymbidiums. Medium
bark 1/4 to 1/2 inch is good for Cattleyas, Phaleonopsis,
Dendrobiums, and Laelias. Coarse bark 1/2 to 1 1/2 inch
is good for potting Vandas and Ascocendras
For mounting orchids the
materials of use are cork bark, and hopu bark. Many
orchids like to grow mounted.
