Is it possible to create a natural woodland floor – e.g. wood anemone, bluebells, wild garlic, primrose etc etc – in an (acidic?) site that was pure bracken and understorey of mature larches? If so, how? I guess the thick layer of larch needles + dead bracken leaves makes it very hard for anything else to grow. yet I’d love to make this area more attractive to people and insects/birds.
Larch likes dry ground and it can be difficult for ground layer plants to get going. Keep the bracken under control and adjust the canopy as suggested. This will happen naturally as the trees get older in any case.
