    Default old pseudobulbs

    Hi,
    Can or should old pseudobulbs be cut off? Read somewhere that they continue to produce and store food for the plant. Attached is picture of Catt with old pseudobulbs that are wilted and burned. They are unsightly so was thinking to cut them off, but afraid it would traumatize the plant.

    The old pseduobulbs do supply energy to the new growths of the plant. Sometimes, you will also find an eye at the base of the pseduobulb that can sometime become a new growth if needed. Can you remove some of them without hurting the plant? Sure. Just try to leave at least three or four healthy old p-bulbs with the new growth. When you repot this cattleya, place the new growth toward the center of the pot. This will allow it to continue to grow inside the pot and keep you from having it step out of the pot so quickly.

    Thanks, Bruce!
    Guess I will have to repot soon, although I was not planning on it yet since nothing has grown outside the pot. What would be the best time to repot? Should I wait after blooming (there are two pseudobulbs developing sheaths at the moment) or could I do it now?

    Overall, the plant looks dehydrated.

    Judging from the appearance of the leaves and pseudobulbs, and the calcium deposits on the bottom of the pot, it is very likely that several years worth of calcium/salt deposits
    have encrusted over the plant's roots and are impeding the water uptake.
    This could be what is causing the plant to look dessicated. The roots might still be functioning, but not at maximum capacity.

    When was the last time that you repotted this plant?

    Oh thank you for your comment. Actually, I have never repotted it since I received the plant on Jan 2006. I'm so afraid to disturb it. Yes its a bit dehydrated because we're having really warm weather now, up to 35C, and I have not watered it often enough to keep up with the heat. It's got 2 new pseudobulbs, though, and perhaps will wait for the bloom before repotting.

    I buy plants from a local grower that often has white mineral/salt deposits obvious on the pots. I heat up water, so the water is warm not hot...and soak the pot for about 10 minutes or so. It leaches the salts back out of the pot. If one soaking does not completely remove the salts, wait about a week or two...when the plant has dried out again to soak it. You will see the plant perk up almost immediately. Sometimes when a plant has gotten dessicated, it helps to soak it occasionnally. Just make sure air movement is high when they are very wet...
