Orchid trying to escape

   

Last time this orchid flowered it did the same.

I repotted in fresh compost, standing up in the middle of the pot and quite well down in the compost I thought but it has done it again. Moved over to the side of the pot and come quite far out of the compost. The flower is nearly on the floor when stood on a low coffee table.

Has anyone and suggestions how to keep it firmly in the centre of the pot with its roots in the compost?

    I've staked mine!
Aren't they aerial roots that are meant to be exposed?

Agree with veggie

Most are aerial roots but not all.

I did try 'staking' it but the stake is only tied to the 2 old stems. It would have helped if the flowering stem had been tied as well but I think it would still have keeled over. The total length of the stem is 3'6" as it is a shoot off a previous flower stem. I think in future, I'll cut all the old stems out so it can't do this again and make sure the new stem is tied to the stake (and burned if it tries to escape again).
