I have a vanda orchid in a small wooden type tiny in size with only base in box with roots coming open slots sides. It hangs from a black metal stand in my Florida room. It looks great and I have had it since February of this year. I grow many different kinds of orchids but never this type. All of my other orchids always say to trim dead or dried up roots off. I haven't done it to the vanda but did so today. I should of checked this first, so I sure hope I made the right decision. I have always had luck in growing orchids so I guess that's why I trusted myself first. Please tell me if this was the correct decision to of made. Thanks. Mellanie Crooker
Cutting Dead Roots Off Vanda Orchid
Certified GKH Gardening Expert
Vanda roots that turn brown or mushy have died or are aging.
It is fine to trim away these roots. Leave only the healthy green or white roots.
This may also be the time to repot your Orchid and give it a larger basket to grow in.
Dividing in late spring or early summer is recommended.
