Giving some more thoughts on the snail problem to keep them at bay i
remembered a device that i used in asia to catch rats.
It was a plastic plate around 16 inches in diameter on which was
applied some very sticky goo substance. In the centre was placed some
bait and when the rat stepped onto the plate to get the bait he got
stuck to the plate until he was despatched .
Now this goo stuff is extremely sticky and would have no trouble
stopping a snail as it has no trouble with an angry rat.
All that is needed is to cut the plate in 2 sections allowing a hole
in the middle for the plant stem and the 2 parts are assembled around
the stem.
Then every day or 2 all that is needed is to pull off the snails from
the goo.
This should stop them all in their tracks for sure and is a simple
device ,no need for pellets or toxic substances or waste of good beer
!
The only thing is maybe birds might get stuck by accident so a wire
mesh cover over the plate offset by about 1.3/4 supported on a
central pedestal allowing the snails to get onto the sticky plate.
