Dendrobium Spectabile Pseudobulbs Cracking!
So I have been growing a den. Spectabile since February. It has been doing great, sending up several new growths, lots of new roots, etc. However, I just noticed while watering this morning that, in just what seems like overnight, the two newest pseudobulbs/canes that are maturing have developed splits or cracks running vertically along the sides.
The plant sits in 2-3 hours direct sun around mid morning in northern Louisiana. I give it a splash of water through the bark medium that is capped with sphagnum to help keep this guy moist, and once a week I give it a good soak. Lately the nights have dipped down into the low 70's and upper 60's. Not sure if this temperature change caused this or if I am not providing proper care that has lead to this.
Anyone know what the possible causes/cures could be?
