What to do/grow at the foot of Leylandii hedge?
A few ferns, scruffy st John's wort, angled periwinkle grow under the hedge. Wondering if there is a solution to make it look 'neat and tidy'? Plants? Gravel edging? Desperately need some ideas!
( too costly to remove/replace it but it has good points - It encourages birds, wildlife and is a good pollution/sound barrier to some extent)
