Poo probably!  That doesn't really bother me if it is, as we put animal poo on our veg anyway.

for London Brick

Well, I'd certainly heard the expression 'sh*t a brick' !!

So where had all the tomato seed come from in the 1st place then Henry?

Passed on by birds,self seeding,and gully suckers.But most would have come from treated human waste.The seeds can suvive most things.

One site had the beefeater type of toms,massive in size and taste.
They were the best and I entered them into a competion for giant veg,and they won their class hands down.
Afterwards the veg etc was auctioned for charity and these toms didnot get one bid.  I wonder why :?:

Some of our best tomatoes this year were growing in the chicken straw/poo heap.
