Gall on Emerald n' Gold Euonymus


By drc726


Last year a member asked why her Emerald n’ Gold Euonumus hadnt grown? I suggested it was a growth ( I mistakenly called it canker) because thats what happened to some of mine.
I had 18 Euonymus and about 6 have succumbed to Crown Gall. Today I had a look to see why one has not grown although it looks very healthy, I found 5 galls on it, (they are not visible unless you look for them) I have consigned this plant to the bin.
‘Emerald n’ Gold’ is a cultivar of wintercreeper euonymus, which is particularly susceptible. Young galls are smooth and greenish-white to tan. As they mature, galls become dark, hard and woody; they eventually crack and decay. Crown galls are a solid mass of tissue all the way through, unlike insect galls.
Plants suffering from crown gall often exhibit stem dieback and stunted growth, because the galls disrupt the movement of water and nutrients between roots and leaves. This certainly detracts from their ornamental value, and severely infested plants may die.
The severity of the disease depends on the size, number, and location of the galls. Galls at the crown of young plants cause the greatest damage, and can eventually kill them. Crown gall may have little noticeable effect on older, established plants.

No one seems to know about it TT But now, when ones does not grow I look underneath it. This one was planted about 10 years ago yet only about 8" high by 18" while the other one planted at the same time is over 2ft high by 3ft. Because it looked ok I didnt check it.

Thanks for this Denise, I have various Euonymous varieties (about 8 of them) and wasn't aware of this problem either. I've always thought them to be very trouble free useful shrubs. Does it affect the other varieties as well? I'll go and have a look at them, although I think they all seem to be growing OK.

I appreciate this as well,Denise,as I have 5 of this variety,and never heard of it before either.all mine were grown from cuttings a few years ago,so they are well established,but will definitely keep a look out now,just in case..Thanks...

Thats exactly what they do Fluff horrid things. Yes it can be found on the other varities Lily but not usually as much.
