Hi, I am brand new to the group. I have a gorgeous 1 1/2year old Doritaenopis Orchad which is my first orchad to ever live! It came with one flower stem/spike and had two this year that were multi branched and full of flowers. Now I have FIVE more spikes growing and my husband says I need to repot. How do I know if that's true? It is doing incredibly so I feel like I should just let it be???
