I have a couple of apple trees on very dwarfing (M27) rootstock, than I have planted into patio containers, approximately 50 litres each, with a top diameter around 50cm.
I am wondering whether I should plant anything around the edges of the container under the apple trees.
I was thinking of either strawberries, or some herbs, but was wondering whether they should have the container to themselves and cover the ground with bark mulch or something.
I'm in Cornwall, United Kingdom. The containers get good sun in summer, but not much in winter as there is a building to the SW of them which the Sun doesn't get over during the winter.
