I forgot to write that I checked it today and under the leaves I found little white worm like bugs on it also.

Your euonymus shrub has euonymus scale (insect). When the infestation is heavy, it's difficult to treat and if it were mine I'd take it out, replace with something not susceptible to scale.

Here is a link that might be useful: To read up on scale of euonymus

this plague.. is why i got rid of all of my euonymous ...

there are so many things that can be used to replace them.. thats its simply not worth the effort.. or cost.. to treat them ...

there is a shrub forum.. if you want to talk about replacements....

if its weakened to that degree, just get rid of the plant. Otherwise it would be far more costlier to buy chemicals to kill off those bugs. (and I do hate using pesticides and I only use it so sparingly).

They are easily resprouting. If you still want that shrub you can get rid of the bulk of the problem by whacking it off close to ground level and removing that VERY infested tissue. Rake the area around it to remove all residue and spray it heavily with a horticultural oil. It should resprout from clean wood and resume growing. I keep fairly large beds of various euonymous, and have only had a scale infestation start in one bed once in the last twenty five years. I did just what I told her to do, and by the end of the next summer you couldn't tell there was ever an issue and the scale never returned. That being said, this is a common little shrub and easily and cheaply replaced.

I agree with Calliope that cutting this shrub to the ground and letting it grow back is a good alternative. But do not do it now! A heavy pruning at this time of year will trigger a flush of new growth which is the last thing you want to happen as Fall approaches.

Wait until late winter or early spring.

Since you have not showed us images of the whole plant, it's impossible to judge the extent of the winter damage. It could be that the stems, trunk, and even roots are split from the severe cold. Yours wouldn't be the first to suffer extensive damage this past winter.
