Indiana Wild Raspberries
The wild, black raspberry (Rubus occidentalis) generally will
bear fruit in the month of June here in NW Indiana.  Depending
on the weather, it can be a bit different.  The southern part
of the state may be a bit earlier.

These raspberries are actually part of a family of plants that
also includes roses.  These fruiting plants produce fruits that
are referred to as drupelets.  These drupelets form the berry
that you are picking.  These berries, or caps, are hollow.  This
makes them pretty easy to pick in my mind.  You will still come
away with some purple fingers, but I still love picking these
berries.  

There is a genetic abnormality in the black raspberries that can
sometimes lead the plants to produce yellow fruits.  I think
these fruits have less taste in them than those that are black.
These plants will produce yellow fruits every season.

Raspberries contain a ton of good stuff in them.  I am not going
to get all scientific with you all, but the antioxidants in
these fruits is awesome.  They also contain a boatload of fiber
per serving.  A great source of vitamin C and manganese.  The
amount of antioxidants in raspberries put them up there at the
top of the list of other fruits.  They are a bit behind the
wild blueberry and the cranberry, but if an apple a day phrase
is true, you will need to eat raspberries about every other
day.

I often have to tell people who come out to pick wild raspberries
not to tear up those light bluish green plants that don't have
any fruit on them.  They ask why, since they have no fruit.  I
tell them that those plants are the ones that will bear fruit
the following year.  If you are going to try to give care to
your wild raspberries, then after you have picked the berries
from the plants this season, you can cut those plants back.
This will give you a little more room to operate when picking
berries in the future.  That is a little bit too much like
work for me.  These aren't as bad as the black berries that
I pick.

You can prune these plants back early in the year before they
get going in the spring.  I would still leave the plant about
four feet tall.  This will also lead to branching of the plants
and potentially create more berries to pick.  Something else
that you can do to aid your berry production is to fertilize in
the spring before they start to leaf out.  I prefer to do it as
the last of the snow just leaves.  Then hit them again about a
month or two weeks before the berries are ready to pick.  This
will help in production, if you get the rain.  If you get the
rain you need, you should get all the berries you want.
