on my raspberry this will no work properly...
I'll try it on my breadboard, but no success !
Input Drive 2.5m (8ft) long
75mm (3in) diameter posts into the ground to a depth of 75cm (30in) at 5m (15ft) intervals.
Stretch 12 gauge (3.5mm) galvanized wire between the posts at 60cm (2ft) vertical intervals.
Single fence with parallel wires
Drive 2.5m (8ft) long and 75mm (3in) diameter posts into the ground to a depth of 75cm (30in) at 5m (15ft) intervals.
Attach two short horizontal lengths of timber to each post, one at the top, and one 60cm (2ft) below.
Stretch 12 gauge (3.5mm) galvanized wire in parallel lines along the ends of the horizontal lengths of timber to create two parallel lengths of wire along the fence.
Stretch thin wire or garden twine between the parallel galvanized wires as cross ties, every 60cm (2ft) along.
The raspberry do not need tying in, as they will be supported by the parallel wires and cross ties.
This system is well suited to autumn raspberries, and increases yield in a small space for summer raspberries.
Tying in of canes is not necessary. Picking is more difficult, and there is a greater chance of fungal problems in the more crowded conditions.
Of course i don't use the good model of Rasberries
