Spiranthes Care

[AnonYMouse]

I have both odorata and sinensis in the rosette stage. I got the sinensis a few weeks earlier than the odorata. The odorata bloomed but the sinensis hasn't; I believe the sinensis blooms earlier and I missed that window.

Both are in a moist, gritty, pebbly, small wood chippy, peaty mix (a commercial "bonsai" mix that I added perlite to). Full afternoon exposure. Temps might have gotten down into the mid 30's °F overnight last week (lowest so far).

There is an excellent article on sinensis at Botanyboy but haven't found an equally comprehensive write up on odorata.

Can they be treated the same?

I plan on feeding them low doses (25-50 ppm N/almost every watering) when I see the rosettes start to elongate.

Does that sound right? Am I forgetting anything?

Maybe be sure to flush the soil with relatively pure water every now and then to avoid salt build up in the roots

I grow both as well. Odorata I just have in the ground in a sand/peat mix here in zone 7A, sinensis I have potted in coarser sand/peat.. The sinensis is I put in the ground did not make it through the winter but those that a friend put in the ground just outside Boston in zone 5 did survive the winter in the ground alongside his other Spiranthes.
