Rootless Phalaenopsis: Yellow Leaves at Base

[aliceinwl]

If the keikis have roots, they can easily survive but not in potting soil. You want a pot that just fits the roots (if the pot is too big it will tend to stay moist too long). Orchids breath through their roots and potting soil will smother them. I like bark as a substrate for mine. When the bark goes dry (roots will turn silver) it’s time to water. If you can’t see the roots in the pot you can use weight (pot will feel lighter when dry) or check out the sticky thread at the top of the forum about using skewers as a means to determine when to water.
