Yes, during the summer months we follow No Mow May, Let it Bloom June and Knee High July and therefore do not cut back wildflowers, nettles and seeded grasses because of their importance to pollinators and birds.
Wildflowers are left to go to seed and are shaken when after they die back to optimise their reseeding. However there are important exceptions – we will keep clear towpaths and trails that are open to the public and will follow a proactive schedule of weeding/tidying/clearing of those paths (including a 0.5m margin).
