Blackberries/raspberries in pots
 

I've read that blackberries and raspberries can be grown in pots with a diameter of at least 15". Will a pot that size really only accommodate one plant? It just seems to me that when we had berries growing in a pasture as a kid, they were quite happy to grow in a great tangled heap. :)

And did they have a root space of just 15 inches?

I grow raspberries in 30 litre tubs, 5 canes to a tub with a wigwam of
bamboo canes for support. With three tubs, we have enough for
ourselves and some to give away. I use a mix of John Innes No 3
compost and Perlite (you can use grit but the Perlite does the same
job - helps drainage - and weighs less so tubs are easier to move
around) with 25 litres of compost to 5 litres of Perlite. Initially I
mixed in a couple of handful of bone meal. I work another handful into
the compost each spring and feed with a high potash fertiliser (e.G.
tomato food) once the flowers start to develop.

One tub is now in its fifth year; the others are in their second. All
are doing well.

Hmm. IME perlite and vermiculite increase the weight of tubs because
they hold so much water. I haven't tested this scientifically BTW :-)

And when they dry out they reduce the weight.

You can use Tesco "Dustless" cat litter instead of Perlite (actually
it's used as a substitute for vermiculite), it is also sold as a soil
amendment in Holland, but for 5 times the price... ;)

I think doing blackberries and raspberries in tubs sounds like a
brilliant idea. I always have a terrible time keeping them weeded in
the open; fresh compost would keep it down to light pot maintenance.

Two questions: do the pots need protection in winter? and how well to
they handle missed watering?

Thanks,

The tubs stay out in winter with no protection and no problems (I also
have dwarf apple trees in tubs). I can't answer your question about
missed watering as so far I haven't plus the weather's been wet enough
this year anyway. The tubs I use have drainage holes in the bottom and
around the side so don't get waterlogged, by the way.

Re watering,if you use a water retaining polymer mixed into the compost/
soil it will reduce the amount of watering required.

Thank you for the help!
