New Growths on Pseudobulb. Pseudobulbs are the swollen orchid stems where leaves are attached to. When the leaves die and abscise during the season, pseudobulb is not relieved of its function. Leafless it may be it serves as a reservoir of water and nutrients for the plant. The picture you see above is a product my one mistake. I detached the pseudobulb from the plant and planted it to see if new plant comes out. This is not recommended since it would deprive the rest of the plants from the good stuff stored in it.
New growths showing up
My inexpensive potting mixture is working. Last May I experimented on the potting mixture that I used to repot the orchids. I observe that the plants seem to like it as indicated by the number of new pseudobulbs coming out. Spike is the term used to refer to the inflorescence or the flowers in cymbidiums. As a general rule, a spike comes out at the base of each new pseudobulb. If these plants continue with their current growth trend then I can safely say that you and I can save a lot of money by making our own cymbidium potting mix.
Cooler spot. Cymbidiums love the sunshine but the blazing summer light intensity is too much for these traditionally-understory plants to bear. For now I have moved the orchids to a more shady part of the yard. The good thing about potted plants is that the microclimate can be adjusted easily by moving them around.
