I have a yellow honeysuckle vine that is growing very well except last spring it developed a sticky brown substance all over the flower buds and leaves, this substance seemed to kill the flower bud and it didn't flower at all. What is it and what should I do if it happens this year?

Check your plant closely for signs of aphids, scales or mealybugs. These are the most commonly found insects which feed by sucking juices from plant tissues. They exude a sticky substance called honeydew and their feeding can cause yellowing of leaves. If you find colonies of insects, the sticky substance is their excretement. Control the insects and you'll eliminate the source of stickiness. You can hose your plant off to dislodge the insects. Insecticidal soap sprays will help eliminate the pests.
