Grass for an orchard?
I have recently inherited a small and very neglected orchard - only five trees, surrounded by 6ft privet hedges. I've been slowly, methodically (obsessively) digging out nettles, ground elder, ivy, dock and sycamore seedlings. I don't want to get in a rotavator or put down weedkiller because there are many bulbs in there which are spectacular in springtime, as well as several clumps of ornamental grasses. I know I'll never get rid of ALL the roots, but I think I've done a fairly good job of it and it's beginning to look like the pretty little secret garden it's supposed to be.
Ideally, I'd like to extend the existing narrow grass path so I can mow around all the trees (on the highest setting because the surface will always be somewhat uneven). Can anyone recommend a suitable fast-growing seed mix? Could I turf it for instant results? Am I wasting my time? Will grass never compete with the weeds unless I bring in the big guns?
Any advice gratefully received!
