I have been wondering about using this on my Cornus stump. That would be
to accelerate its decomposition, of course, not to kill it as that would

But I just had a look at the Westland Garotta pack in my local garden
centre, and there is absolutely no mention of what it contains. I
thought it might say "Ammonium Sulfamate" somewhere, but there's not
mention of it. However, on the information sheet at
https://www.gardenhealth.com/wp-content/uploads/2019/01/Garotta.pdf it
states that the hazardous ingredients are "Silicone (sic) Dioxide 35 -
40%"* and "Limestone 35 - 40%".So it's sand and limestone. No ammonium
sulfamate to be seen.


I have found it effective for starting a smaller cold heap. YMMV
You can cut it with ammonium *sulphate* to make it go further.

It is a mix of inert minerals and freeze dried compost fungi/bacteria.

I can't see it doing anything useful to a tree stump. Loading it with
potassium (or ammonium) nitrate and a copper nail would be my
suggestion. In a dry year you can get it to smoulder away and in a wet
one it rots faster with the added nitrogen and a trace of copper. That
is how I got my former big apple tree root out.


I've had some KNO3 for maybe 30 years as I used to mix my own specialist
low-phosphate fertiliser for proteaceous plants. Although I haven't got
any copper nails, I've got plenty of copper wire. Maybe it'll save me
wasting any money on ammonium sulfamate.
