Cool growing orchids need a minimum of 7C -
10C (45 - 50F) during the winter and a maximum of 24C (75F) during the
and similar types - butterfly orchid
This type of orchid comes in such a wide
variety of shapes, sizes and colours you must be able to find a spot for
one or two in your house. The flowers of this type of orchid are usually
formed many on a flowering spike and are almost ready made flower sprays.
Some but not all are highly fragrant too.
||As with Cymbidiums they don't like draughts of either hot or cold air but
do like a good air circulation. Keep these orchids in at a minimum of 10C
(50F) during the winter months rising to no more than 20C (68F) during the
summer. Applying a fine mist with a hand sprayer once a week is also
beneficial as they do like a little more humidity than Cymbidiums. Another
way of providing this humidity is to stand the plant pot on a tray of wet
pebbles or stones, but not standing the pot in water as DEATH will
certainly be the result.

Odontoglossum's are similar to Cymbidiums
and like high levels of sunlight but not directly otherwise the leaves
will scorch. You can keep Odontoglossum's outside
during the summer months in a similar position to that required by
Cymbidiums but less exposure to wind otherwise they may blow over as they
are a much lighter plant. During the winter keep your plants in the brightest position
you have but again keep out of the direct rays of the sun otherwise the
leaves may get scorched.

These plants have thin(ish)
roots which like being kept evenly moist all year
round. During the summer months they can be watered a
couple of times a week in warm weather, less often if it's
cooler. Don't be tempted to give a 'little drink' to your
plant because it is damp and not quite dry as they don't
like it - give it a couple more days and give them a good
flush through. This also helps to flush out any unused plant
food. Water during the winter at 10 - 14 day intervals and
water them by flushing the pot through with tepid water -
not cold from outside or the tap as this will shock the

During the winter months feed the plant no
more than once a month otherwise the roots may be burns by unused plant
food. From spring mid summer feed them every 2nd or 3rd watering with a
high nitrogen plant food which will encourage strong growth and big pseudo
bulbs to develop, from mid summer through to the following spring use a
high potash feed to harden the pseudo bulbs and encourage more blooms.-
Dilute the plant food to quarter the recommendation your pack suggests.
Repotting Odontoglossum's should be done in
the spring annually as the new growth has started, wait until the new
emerging growths are approximately 2 - 3 inches high and use an well
drained compost such as medium grade bark chippings. New roots will quickly grow to
take advantage of the fresh compost. Splitting the plants can also be
undertaken at this time of year and each division should have at least one
new growth and two back bulbs. See Division
