I would like to hang my amaryllis/hypocanthas(?) outside on my house wall
during the summer. I have tried putting them at ground level and the
snails ate the lot, including the bulbs. We all know that snails can
climb to any height, so ideas please, to stop them climbing up a brick
wall and into my pots. Many thanks.

Slug pellets or Vaseline Petroleum Jelly around the underneath of the rim of
the pot or both.
I thought Amaryllis belladonna should be planted in the ground, mine are,
and they flower every summer once the leaves have died down.

Do you mean Hippeastrum?
