Orchids in garden soil?

[Bulbopedilum]

Can any orchids grow in regular garden soil? I'm talking plain old dirt. No humus or anything. Just dirt that you grow tomatoes in (minus fertilizer, I never fertilize and I don't know why.)

Asking because I'd like to add a little orchid-ness to my front/back yard

[rbarata]

Probably Bletillas, Pleiones and some more

[Subrosa]

Stenoglottis and Cynorkis

[estación seca]

It depends on your climate. Do you have a strong wet/dry monsoonal climate? Many Habenaria have a growth pattern like that.

I second rbarata on Bletilla striata. My mother grew them in heavy clay, my sister grows them in almost gravel and I grow them potted with all sorts of material mixed in (whatever I had at the time). Lots of sun in all cases.

Thanks for all the answers but doesn't bletilla have a dormancy period? I can't give a dormancy period outside.

My climate is the rainy/dry climate.

Bletilla rest is: drop its leaves and the bulbs remain under the medium. Basically, the plant disapears until next spring.

Look into various Habenaria, Eulophia, Oeceoclades, Calanthe and Phaius.
