Quite a few of my 'rescued' Walmart orchids are now putting out flower spikes. Most are only a few inches long but two of them have spikes that are about 18" long and one of those has buds on it. Those I don't want to mess with but the others, do I need to stake them or just let them go as they please? I will say that I'm leery about staking as I'm afraid I'll break them off.
