I have wall fruit on the south side and an orchard of plum, pear, and cherry trees on the north side.
These are a species of slugs covered with shell, and which are very destructive to wall fruit.
They had originally been set out as wall fruit, within a few feet of the front wall of the house, on its southern side.
This experiment may easily be tried on wall fruit, and has been found to answer.
wall fruit and shrubs must be now particularly attended to, in divesting them of every foul or decayed substance.
