Beginner Cymbidium - when to repot?

[ajeatoo]

Hi,

I wasn't sure whether to put this thread here in the beginner forum or on the cymbidium forum... move it if it needs to be!

I purchased my first cymbidium several months ago while it was still in bloom (can't remember when, during the winter in any case). It stopped blooming a few months ago so I cut the bloom spike about 1' above the base. It's been doing fine from what I can tell and even weathered the tips of its leaves being chomped on by my naughty great dane!

Anyways, so I have it sitting a few feet away form a south facing window which is always open so it gets a nice breeze and that room is also cooler. I water it when it has just about dried out.

My question is how do I tell if it needs to be repotted? It's not too big so it's not like it needs to be divided. I have done some reading on them but I don't know how to tell if the medium is broken down or not. Within the last few months it has been putting out lots of new leaves and I noticed when I watered yesterday the pot is starting to be mis-shapen because the roots are pressing on the pot, you can feel them pushing on it.

I have attached a few pics. Should I leave it for another year?

Thanks!
