I have a mugo pine that is about 20 years old. It has been dying back slowly each year. It has a white sticky stuff at the end of many branches. Its the consistency of honey. I have tried spraying it with insecticides with no success. Can you help?

When subject to poor drainage, compacted soils, drought, excessive mulch, lack of sunlight, etc. mugo pines can be susceptible to possible insect and disease problems. The white substance may be sap, or possible insect. Break open the tips of the branches and look for larvae.
Send us digital photos of the whole shrub and affected branches so we can see what you may be dealing with.
