I have raised beds (Zone 5) of strawberries, raspberries, blueberries and
currants. They all do well in the raised beds and are easy to take care of. A
couple of things to think about. I tend to have to water raised beds more than
the blackberries, black raspberries, grapes and Golden Kiwi raspberries I have
in the ground. The soil is better in the raised beds but tends to dry out a bit
faster than I would like. May have to do some amending to help with water
retention in the raised beds.

The other question I have about raised beds is would raised beds freeze harder
than the ground? I've got pots of plants and trees that I bring in the garage
in the winter to prevent them freezing solid and killing the plants. Are the
raised beds really just great big pots or because of the connection with the
ground raised beds won't freeze that hard. We've had mild winters (IMO) here yet
I still bury and I mean bury the raised bed in leaves in the fall to prevent
them from freezing super hard. I don't know if that help the beds or not. I
don't if my worries about the raised beds freezing are valid but it is something
to think about.

Like another poster suggested, I do have my strawberries and blueberries in a
separate raised beds so I can keep the soil acidic and separate from the plants
that don't need that acidic soil.

I use a mantis tiller in the raised beds. My beds are 4' by 20' and 12" high
and I have three of them made from wood.

So far I like the raised beds and I'm glad I put them in.

I'm considering whether to use raised beds edged with granite or just
plant in the ground.

Are there big advantages to be had planting these materials in raised
beds? It's more trouble and expense to install initially and a bit of a
hassle to cultivate, since I already own a tiller for use behind my
garden tractor, but if the long-term advantages still outweigh the
disadvantages, I'm willing to to go for it.

Any suggestions?
