| The sticky substance is essentially orchid sap. Sometimes you will find a little bead of sap on the tip of a perfectly leaf sometimes as it is growing. I see it usually on my Cattleyas. This is no cause for concern. Your situation seems a little different though as there are so many beads of it all along the length of the leaf. I suspect there is a very small sucking insect, perhaps a mite of some kind. The beads are forming where the critter fed. If this is what it is, the treatment is fairly benign. Give the plant a spray all over with somethign like an insecticidal soap (safe for indoors). Mites are usually fairly easy to get rid of. About 4 weeks ago i found a few in the crown of one of my Phals and got rid of them with only one application. |
