What is Happening Here?

Strange goings-on in the garden? What is happening here? Why is the cast-iron flying pig in for a swim?

It really is simple. When you find two pots of thyme have become the homes of thriving ant colonies, the best way to deal with them is immerse the plants in water (minus the pots) for 24 hours.

Cast iron flying pigs have these lovely little trotters that grasp and hold the plants below the surface.

Every garden should have some. Or rocks.
