i'm new to orchid. bought several orchids last month... but 2 of the orchids got this "yellowing" leaves & "drying" spots on the leaves.. what causes it? could it be lack of fertilizer? or too much direct sunlight? too much watering? or too little watering? can somebody help me? here are the photos of my orchid...

thanks for your replies

Where are you keeping those plants? It looks like a bad sunburn. They need to be put somewhere where they are getting less light, for example under a tree with light shade, or under a shade cloth to block some of the sun.

Very pretty blooms, Winterain, and welcome to OB! I agree with Camille.... too much sun.

Your dendrobium likes to dry out between watering and loves being pot bound.

Yup yup, I can relate to the buy and buy part!

It's a dendrobium and they do like sun, but not direct midday sun where it would burn the leaves. I also think that type you have may need a winter rest. Not sure when for your area, but where it's blooming now, I'd wait on that. You might want to look that up, though. Happy growing!

That's a phal type Dendrobium, so they don't need a winter rest. You can treat it the same way all year round, especially seeing the type of climate you have!

oh i see.. thanks camille

Camille, I get so confused at which dend. needs winter rest. I don't know the dends to know what's what. Is there a book that helps with that? I know there is a thread here on OB about what needs winter rest, but if you have dend noids....and don't know, it isn't helpful.
Is there a way of telling types of dends? Rule of thumb? Something?

Appreciate it, and sorry for
