Oncidium Orchids Care

Water when the mix just approaches dryness. This will mean about every 5-7 days. A way to check the mix for moisture is by sticking a wooden pencil into the mix about 3''-4''. When you pull the pencil out, check the wooden end. If it has turned dark in color, the mix is still wet and you should wait a day or two. Oncidiums prefer clean water without a lot of mineral content. Therefore growing best when you use distilled, reverse osmosis or rainwater. Check out our Kent Marine page for more information on reverse osmosis systems. Do not use softened water.

Feed every other watering during the summer, and every third watering in winter.

Grow in bright diffused light; east or west windows are ideal. South windows will work but one should be careful of the brilliant sun that will come in during the fall through spring months. If you have miniblinds or sheer curtains, you can break the light so that it is more diffused. One of the best types of artificial light you can provide for your orchids is by using L.E.D.
