. I think Bealleras and Oncidiums do really well in slatted baskets potted in part sphagnum and part small bark. I fertilize once a week weakly and keep the media moist. Can you hang the plant outside and water it with the hose every day or so. I've had this oncidium for focus or five years. It hangs on the porch from March to late October, then comes inside when it is colder.
