I planted out some hanging baskets a couple of days ago, just in time
for the temperature to drop to near zero and the heavens to open and
rain constantly for over a day.

When I went out to look at the baskets today the surface of the soil was
covered in little lumps of jelly (like little cubes of gelatin). Does
anyone know what that is about?

I'm guessing something out of the soil caused it (since it also happened
on a patch ground I used the same compost on), but I have no idea what
it is. There was no way it was snails, frogs etc. since the baskets are
hanging up on chains.

Any ideas?
