I'm over run with Spanish Bluebells.
We purchased the house 2 years ago and the previous owners let the bluebells seed down across the whole garden over the 20+ years they lived here.
Where possible I've dug them out but they've seeded amongst dry stone walls, tree roots etc. These areas are almost impossible clear as the stems just snap and leave the bulb behind ready for next year.
Can anybody recommend a suitable weed killer that I can treat the problem areas with and the best time of year to apply it
