If you are growing your orchids indoors you may want to be more selective about the range of colours from your orchid blooms. With such a vast choice of hues and shades, it is possible to arrange your colour schemes to suit any room or personal choice. The following charts will give you some at-a-glance ideas for this.

Orchids that benefit most are lightloving, cool-growing types such as cymbidiums, odontoglossums, coelogynes, encvclias and dendrobiums, all of which have fairly robust foliage that may become a little spotted or marked throughout the course of several months but will not come to any harm. Those orchids with softer, wideleafed foliage, such as lycastes, anguloas and the deciduous calanthes, would very soon become notably spoiled by blemishes as a result of the effects of the weather.

If you also choose your orchids to bloom at different times of the year, you can have a plant in flower for most months of the year, ensuring that your favourite position is always filled with at least one plant in bloom.

During the summer, the aquarium can be left open at the top; close it down only when warmth needs to be conserved. By setting up a horticultural fluorescent light tube above the plants, it is possible to place the aquarium in an unlit corner that would otherwise be unsuitable for growing orchids. This idea can be adapted to a smaller or larger degree.

If you do not stand the plant on a damp base, you will need to remove it for watering and replace it after the pot has drained. The flowers of some orchids can also be highly scented, which adds immeasurably to their overall appeal.

Alternatively, you can build your own indoor growing case as large as conveniently possible and with the inclusion of electric lighting. This will provide a permanent home for those plants that do not need bright light. These include the phalaenopsis and paphiopedilums.

It blooms during the autumn and is highly fragrant at night. Well-chosen colour combinations can create beautiful effects, as is shown by this display of pale pink Phalaenopsis schilleriana and the deep pink P. Mad Milva. Orchids can be displayed in most rooms in the house.

Orchids that have outgrown their pots are also at risk of being top-heavy and are easily knocked over and damaged. These same orchids are also extremely difficult to keep watered, and once they have become dry it is almost impossible to get water down to the roots without a long soak in a bucket of water. Other orchids better left where they are include those that are producing their flowers during the summer period. Developing buds and flowers are the first to suffer from dampness, rain and wind. It also becomes difficult to keep the buds free of aphids and attacks from slugs. Newly repotted orchids should not be taken outside until they haw started to make their new root systems.
