I have bought an Coelogyne cristata orchid plant believing it to be a good beginner's orchid.

It has grown well but it has not flowered, can you tell me where I am going wrong?

Coelogyne cristata is small-growing orchid that should flower in the spring.

But unless it is given a definite rest in the winter, it is not likely to flower very well, and this is probably why your plant has not flowered yet.

At the end of the growing season, withhold water from the plant and keep it dry.

The green pseudo-bulbs will shrivel, but do not worry, as they will soon recover when watering is resumed in the spring.

Coelogynes also resent disturbance, and should be repotted only when they have outgrown their containers.

I have a cymbidium, it in my greenhouse and it looks quite healthy.

My query is; the pot seems to be full of green bulbs, does this mean that it needs repotting?

If so, when should it be done?

The green bulbs are pseudo-bulbs, and repotting is not necessary every year and should be done only when the plant is overcrowded in the pot.

This most not be done, however, until May, or until after the flowers have faded.

This should give the plants time to recover and make new growth before the end of the season.
