I have what looks like a dead patch at the base of a Goldcrest Shrub. Its 13yrs old and about 10-12 ft high. I had the same thing happen a few years ago to another Goldcrest which was planted at the same time about 10 ft away, the dead patch spread up half the height of the tree which was also about 10 ft high and I ended up having to cut it down.What might be causing this?The trees have got too big for their environment perhaps? They did fine for so long, Is there anything I can do to prevent the loss of the second tree also? Thanks

Just the Goldcrests or have you lost any other trees?

Cats? Dogs? Honey Fungus? Can we rule those out?

If you clear away the dead bit, is there any evidence of fungus or a 'mushroomy' smell?

I heard they don't like being trimmed, is that true?

If you cut back too hard that section will die back. The new growth only appears on the very extremities I believe. But I am open for correction.

You can trim them, just not into the old wood.

If it is very dry, I'd carefully cut out the dead stuff and give it a good watering with liquid seaweed. It is a good tonic for sickly plants - worth a try.

Google Cupressus macrocarpa "Goldcrest" you will probably be thankful that its dying now rather then 20 years time when you will need a mortgage to remove it.

The times I had to explain to customer complaints about the concept of "Dwarfism". "I bought this 6 years ago and it's 20 foot high!" "Yes Sir, it will get bigger than that over time." "But it's supposed to be a Dwarf conifer!" "Yes Sir, it is. The parent plant can grow to over 90 foot high. You're 6 foot high. If your daughter stopped growing at two foot high, what would you call that?". Misleading labelling doesn't help either. x foot at 5 years/10 years, when it's already a 3 year old plant that has been grown in a container.
