I am clearing my potatoes and want to turn it into a fruit area with raspberries, strawberries, gooseberries and currant bushes with plum, gage and cherry trees along a different boundary. The strawberries though will need to go in an adjacent bed. The bed is 5.2x6.8 and if it is 1800 between rows I was wondering if the raspberries can be planted as a double row with 1800 between double rows. After 6 months as an allotmenteer I realise how much we spend on visiting the fruit farm.
