Aquatic snails will not disperse into the garden, and they do an excellent
job of disposing of rotting plant debris, remember nature has its own
controls, the snails can only grow with food, plenty of food, plenty of
snails, less food less snails.

I have a weed in my path, its a lovely lilac coloured poppy, its only a weed
because its in the wrong place, must be sown by a bird, maybe out of the
bird feeder ?

Hello,

My last pond question! Our pond is full of snails. I think that snails
can reproduce on their own, which is why there are so many. Should I
live and let live or do I need to have a snail cull? Presumably they
will not leave the water and are not a threat to the rest of the
garden?

Thanks.
