Berry plants like mainly sunny spots though some shade can be tolerated and is even useful on the western side of your patch to protect from the harsh summer sun.
Rubus berries, that is Raspberries, Blackberries and other trailing bramble berries, like a soil well drained with a pH 6 that has been prepared by cultivation (hoed). Ensuring your soil is prepared will help your plants establish well and continue growing once they are planted. Make sure that weeds will not compete with your berry plants – keep the soil around the base of the plant clear of all weeds.
In prepared ground plant Raspberries in rows about 300mm to 500mm between each plant. At the end of each row have a sturdy end post – the weight of the berries during harvest time can break a weak post. Put a post every 10m or so to distribute the weight of the plants evenly along the row.
Below is a diagram showing mature, dormant raspberries trellised neatly between wires.

For Floricane varieties prune out old canes each year after harvest. Thin new canes to approximately 10 canes per metre.
For Primocane varieties prune off all canes in the winter after fruiting has finished, to allow new canes to grow in the spring for early autumn fruiting.
Trailing berries should be planted with approximately 1m to 1.5m between each plant. This allows room for trellising long canes. At the end of each row have a sturdy end post – the weight of the berries during harvest time can break a weak post. Put a post every 10m or so to distribute the weight of the plants evenly along the row.
Below is a diagram of trailing berries trellised along a top and bottom wire.
For trailing berries we have found this method to work well. One top wire and one bottom wire, secured to posts with a metal staple, provide support for trailing canes to be wound onto the wire.
Prune each year, taking out all old cane at the base. This is good winter work and is best done during dormancy but before any sign of bud break.
Upright Blackberries can either be fastened to wires (or stakes) with string or sandwiched between wires like the Raspberry diagram 1.
All berry plants require fertilizer for optimum growth. Plants should be fertilized in Spring as they are coming out of dormancy and then as they start flowering, to provide maximum fruit growth.
Watering is also advised in Summer (depending on your rainfall) for fruit size. Late Summer and Autumn watering is also good for growth of the new cane growing for the crop of the following year.
