orchid progress report

This spot is full sun for most of the day, except late afternoon. I had gradually adapted these orchids to full sun, but taking them out for a few hours at a time, especially on cloudy days. The I placed them on the North side of the house, where they get full sun except at the brightest time. Now they get full sun all day. These plants, Dendrobium nobile hybrids, Vaughnera, and a hybrid Cattleya, can take the full sun with no burning. In addition, Cattleya walkeriana seems to to fine in full sun.

This location is against the north side of the house. It gets morning and late afternoon sun only. I discovered that Oncidium hybrids sunburn with less than an hour of full sun. Most I returned into the house again. My South window is shaded when the sun is high in the sky, by the roof overhang, so they don't get as much sun even though this is a south window. All oncidium alliance orchids are kept mainly in that spot, although there is one in this group that is doing OK.

The Phalaenopsis are in the north window, indoors. They are doing well, growing healthy-looking new leaves. The leaves may be getting too much light, based on the maroon coloration, but they may just be a maroon-ish type leaf.

I do feel like I'm doing something right. Not only are they not dead, they are growing. Slowly, but I think that's par for the course with orchids.

I may cut a keiki off from a Dendrobium nobile and plant it. The original cane looks quite wrinkled and dried out, so maybe it's time. I think I'll do that now.
