    Default To water or not to water

    Hello My Betters!

    I have repotted a Cattleya after cutting off, carefully, a good deal of dead roots - some as dry and useless as cardboard! I used a clean razor and applied cinnamon to seal the wounds of living tissue just above the area of rot where I cut. I had to clean cut off whole dead roots, all the way to where they were attached to a main, living root. I was mighty careful as no one wants to damage healthy roots! This much I do know.

    The reason I repotted is that a second older leaf had gone yellow and had to be removed. I sealed the resulting wound at the top of the left intact pseudobulb. I thought it might be an infection but then rethought that as I keep healthy conditions for the few plants I now have: a combined value of 13K lumens of hanging lights, a fan blowing lightly, and a humidifier. new green growth on all plants are present, no sign of diseases to date.

    I then decided to remove the plant from the pot and check its roots. Sure enough, the dying leaves weren't getting enough water! For the record the Cattleya was in the same pot when delivered to my home after purchase well over a year ago. Who knows how long the plant was in the pot?

    The plant is now safe and sound in a new pot with brand new medium. My question is, should I water the plant? It has been since last Sunday that I watered it. I read with respect to Phalaenopses that you shouldn't water them after you have repotted. The principle is to encourage new root growth. Is this true with Cattleyas? The pseudobulbs of my orchid are firm and full so maybe it can do without watering when it will have time to begin growing new roots. While the major root system is intact, this plant will need new roots after my "debridement" of dead ones.

    If I should not water the Cattleya, then for how long, as the plant was last watered last Sunday? Also, I read on a website that the Cattleya, after repotting, should be kept in a place with less light. True? I like to confirm what I read online. Thanks.

    Sorry this is long winded for a simple question, but I want to give you as much background as possible up front.

    Thanks for reading and for any advice you may have,

    Don "Velamen"

    Don, most Cattleya have root growth at one time of the year, usually with new growth development. I always have my medium pre wet when repotting. I would water on a normal schedule. Your healthy roots will still absorb water into the plant

    When I repot and need to remove a great deal of rotten roots, and remember some people do it differently... I sit the plant in a shadier spot for about two weeks, or until I see a nice new clump of roots that are an inch or two long growing, or a new pbulb beginning to grow. If the plant just sits there and looks awful, don't return to regular sun levels until the plant quits moping. Keep your regular watering schedule, unless you have moved it down to a much smaller pot due to way less roots. Obviously, smaller pots dry out faster. If you see spots appearing on leaves you can rub the cinnamon into the bad spot. Best of luck with your cattleya. I hope it rewards you with some nice healthy roots and flowers soon...

    Thanks, Ron and Connie. Much appreciated. Yes, Ron, I forgot to add that I had pre-wet the new medium before repotting. I will water as you say on schedule. Connie, I will have this Cattleya on the floor, further from the light. It is still "moping"!

    My best,

    Don

    As i understand it, you re-potted 1 week ago. This is not much time to allow the plant to re- establish. Your plant may not need watering today. Stick your finger in the medium and see if it is mostly dry or still damp. If it is still damp you might want to wait a few days and check gin. Catts like to dry out a bit. And I would be cautious of a "schedule" One plant may need watered but the next may not.

    Thanks, Katherine. However, I repotted it into water-soaked medium this past Saturday. Then, I watered it liberally yesterday. I should have waited. But I don't think I did any harm. Here's hoping.

    I will not water on a schedule as you say, but err on the side of dryness and observe my individual plants to see if any one needs water. Though a newbie I do realize that overwatering most orchids is a sure way to kill them!

    The Catt is in lesser light where I will let it dry out for over a week, maybe two, while keeping watch over it.

    Thanks again,

    Don

    Golden rule with Catts is if it looks like it needs watering, water it tomorrow.
