Help-I have a dendrobium and oncidium that need TLC

[Mirranova]

Hi Adela,

The one on the left is a Phalaenopsis, and the one on the right is an Onc. I feel that they have likely been underwatered, and the pots that they are in are too big. These need to be in pots that are just larger than the roots.

Both of these plants like a fair amount of water, and Phals don't like to dry out much. I would soak these in a quart of water with 6 drops of Superthrive for at least an hour, and put them in a pot that fits them better. You will want to cut off any brown or dead roots and such. If you pot into bark, be sure to soak it for at least 5 hours or so to help it to retain some moisture.

Once a week may not be enough watering for these two depending on your conditions. My Onc. get watered when they are just dry, sometimes twice a week. My Phals are the same way. I also soak my plants at least once a month for at least 30 min or so by putting the plants into the sink and filling it with water to just below the rim of the pot. The rest of the time I hose them, let them sit 10 min, and hose them again making sure that the medium is well wetted.

I am not sure if these can be saved, but I wish you good luck.
