I have an Oncidium Wild Cat and there is a 'sticky substance on one of the old stalks. Have you ever heard of this? I am concerned that this is something that will spread to the new shoots, and was wonder if it was safe, and how to go about cutting the old stalk off.

Thanks for any help you can give.
 Hi Josh

Yes. I think you do need to fully check it out.



It is likely to be from an insect pest. Have you closely looked at the plant. It may be aphids or something else. If it is an insect you should be able to see it, but it may hide in the leaf bases, around the pseudobulb, or under the leaves. Without more information I cannot tell you more than this. If you find something, you may need to treat the plant. Check with your local garden centre for the correct product, and if you don't know what the insect it, take a sample with you so they can identify it and give the correct treatment


You may cut the old shoot off, but the affliction may have spread elsewhere on the plant, so you still need to check


Regards

Phil
