Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Please forgive us, but Mr. Smarty Plants has been overwhelmed by a flood of mail and must take a break for awhile to catch up. We hope to be accepting new questions again soon. Thank you!

Title: Problems with non-native orchid
Answered by: Barbara Medford

QUESTION:

I have vanda sanderiana that has wrinkled and yellowing leaves.They are located outdoors, northeast section, plenty of morning direct light and still bright even when the sun is at 3:00 oclock.I water daily since the roots are hanging, fertilize weekly weakly. area is windy and cool at night. Cant stop the leaves from yellowing. The leaves do not open up either( they should be "V" shaped if ok should'nt they?

ANSWER:

Vanda sanderiana is an orchid native to the Philippines. Get more information about it from this 2009 Phillipines Orchid Society Annual Orchid Show Vanda sanderina website. The Lady Bird Johnson Wildflower Center has information in our database and research only on plants native to North America. There is an excellent  American Orchid Society website that has sections with education and help on growing orchids.
