Questionwhen do I have the funeral? The leaves are still green and it looks like all the roots but one are dead. I assume that I keep going until yellow and brown even if the roots are not so good? What would you recommend I feed them to stimulate the roots. I don't care about blooms just want to keep them going.....

-----Question-----
I have had great success with most of my orchids except the slipper orchids. The ones that look like a lady slipper. I just got 2 new ones and the base leaf has turned yellow and the roots have rotted some of the leaves are still green with a baby beside it. I repotted and watered a bit but the roots are in tough shape can I save it?
-----Answer-----
Root rot is very common in the slipper orchids. They need to be repotted every year to prevent the potting mix from holding too much water leading to root rot. I recommend repotting now in fresh orchid mix after removing all rotted roots. You will need to sift out the real course pieces of the potting mix, using only particles 1/4 - 1/2 inch. Remove old yellow leaves. Repot in the smallest plastic pot that will accommodate the new smaller root mass. I think your chance of saving the new, young plant are good but it wll be a year or two before the new plant will be old enough to bloom. After repotting, I would unpot the plant every 2-3 months to be sure you have new root growth. Carefully repot the plant back into its new mix after each unpotting. New root growth is the key to the survival of the new growth.
AnswerI have had slipper orchids with only one root make a comback with new root growth. I never write off a slipper orchid until it has neither leaves nor roots. One technique that has worked for me is to construct a terrarium out of a 2 liter soda bottle. These once came with detachable plastic bottoms which I saved. I then cut the top off from the bottle and inverted it into the base. I put live moss in the base and planted the slipper orchid into the base and then inverted the bottle over it. This retained humidity and if the moss grows that is a good sign that conditions are right for the orchid. The good thing about this method is that you don't have to water it or do much checking. It may stay in the planter indefinitely but I usually remove it when the new leves are too long for the container and pot it up. I have generated long new roots and have done this to plants I was ready to bury. One such plant is now in flower in my collection.
