We don’t recommend planting other trees between the plum trees. The 3 meter spacing is already pretty tight and the trees need space to grow. You didn’t mention if your trees are dwarf or standard. It’s recommended to space standard Stanley trees 18 - 20 feet apart and dwarf trees 8 - 10 feet apart.
