By special request, today I transplanted twelve summer raspberries into one of my nine foot by four foot beds. They were in pots, and although they were producing fruit, I hope they well do better with more room to root and with a generous mulch of homemade compost.
I don’t know how I will support them. The nature of the soil at this point of my garden – two to three inches of topsoil over tarmac – creates a problem, but I’ll think about that next spring
I faced another interesting problem, which I hope I have solved correctly.
We have eighteen raspberry bushes, six each of three varieties. Early summer, late summer and autumn fruiting, were in red, black and red pots respectively, but they were not sorted, so how could I tell the autumn fruiters from the early summer fruiters?
A little research suggests that summer fruiting varieties bear fruit on last year’s canes, whereas autumn fruiting varieties bear fruit on this year’s canes. I don’t know if this is an invariable rule, but it’s all I had to go on.
So I have planted those from the black pots – late summer – along one side of the bed. From the red pots, I selected those which had canes that had not yet born fruit. They were planted along the other side. I had already pruned these, cutting down all old canes to soil level. There didn’t seem to be any need to reduce the number of growing canes.
If I’ve got this right, the six raspberries still in pots, which I have pruned completely to soil level, are autumn fruiters. I’ll know for sure next year.
