Repot Oncidium now or wait

[Ross]

Now is a good time to repot. Be sure to remove old rotten and dead roots before placing in new pot. Select a pot just next size up from current (usually an inch or 2 bigger - diameter). Be careful with watering while plant is getting acclimated. You don't want to rot the remaining roots. The new roots will emerge soon from the base of the new pseudobulbs. The old bulbs seldom grow new roots, however under best of conditions the old roots sometimes spring out with new rootlets. I use KLN rooting compound mixed as per labell when I repot. It gives a boost to the roots. Don't forget to soak the new bark overnight in plain water or water with KLN prior to repotting. That will help the bark absorb water in the future. I don't always do this myself.
