Default Orchid questions

"Pam Moore" wrote

I have an orchid (cymbidium) which has not flowered for at least 10
years, but is huge. I hardly ever feed and then it's orchid feed.
It is about to split its pot and needs dividing.
Questions;
1. Is now a good time to do it?
2. What sort of pot is recommended? clear plastic, dark plastic,
or terra cotta?
I've got orchid compost and may need to cut the rootball with a knife
as I think it's too congested to divide otherwise.
TIA


Firstly Cymbids need cool nights to initiate flowering, best done by leaving
them in their summer place outside (you do put it outside in the summer?)
until you hear of a possible frost then take them in. They also like a good
feed, more so than other orchids IME, and chicken poo pellets or wormery
liquid works well from what I've seen.

1. Splitting and repotting is best done when the plant is in growth so now
is OK.
2. Plastic, clear is not needed.

You may find you can shake/tease out the roots to separate into portions for
potting up, throw away old leafless pseudobulbs and rotten roots.
