Sunken beds

Has anyone ever made a sunken bed? I bought 2 blueberry plants and reading up, unless you have the right soil you should plant them in large pots/a raised bed or a sunken bed. They need lots of water (rain water) so pots and a raised bed seem like high maintenance as they will be in an allotment.
Sunken bed seems to be the way to go. It said to dig a hole 2 foot x 2 foot x 2 foot and line it with plastic with some slashes in it. I assume you DO NOT line the bottom of the hole too, right?

I'd imagine you would need to line the bottom. Otherwise the roots would go out into the ordinary soil, and blueberry bushes need ericaceous compost. Also, if you let the roots go too far a lot of the plant's energy would go into them rather than into producing fruit.
That's just my view though and I'm no expert.
I've had an Aldi blueberry bush in a large plastic pot for the past 3 years and I get tons of fruit off it. I just give it tomato feed when it's blooming and fruiting. Plastic pots retain water better, if you use terracotta pots you should line them with plastic that has some slashes in it for drainage. Old compost sacks are perfect for it.

Great, thanks for that. Good to hear the plants were a success.
