I recently got my mother an Orchid for mothers day but as she is a renowed plant killer i told her not to touch it, i myself am normally rather green fingered how ever the orchid has started going brown and two new buds were developing but have since fallen off, the plant is blooming so i donb't understand where i am going wrong? Pics avaliable of Orchid in question on my profile. Thnx
There seems to not be any signs of rotting or fungal infections.
But the leaves are a very light yellow green, which is very consistent with over exposure to light. And the dark markings are consistent with sunburn damage.
If you have a sheer curtain the phal would probably appreciate the protection while still getting that good light.
If not, west or especially east facing windows work really well.
I have success in southern windows, which is really strong sun, but my windows are filtered and double paned.
