So I've had phal. Heiroglyphica for a few months now and it was in spike when I purchased it. The three flower spikes that it was producing seemed to have just quit growing. The plant is healthy and is producing a new leaf and new roots. I figured maybe a change of conditions caused this but if conditions are good for it to grow, why won't the spikes? They are firm and green and I don't know if I should cut them or not. Will they start growing again?
