I have my grapes trained to a two arm spur system and planted on 8 ft. centers. The grapes are planted between the posts, and at every grape and every post I am training a red currant up to be espaliered at about 5 ft. Underneath I have black currants spaced every 4 ft. but staggered. My ground-cover layer is wild strawberry. Not a large-scale system by any means- I have 9 grapes. |
