Our use of the Tsunami 100 takes care
of any problem that might arise with any type of organism or pest in the
apple. Also, after the Tsunami is in the wash for 20 minutes, it turns to
vinegar.

A good way to spread the apple maggot if there are some
in the apples. I wouldn't recommend it for that reason.

For those of you who may make your own apple cider, the apple pulp left from
cider manufacture is a good source for acid loving plants. Since we
manufacture about 5,000 gallons a season, we have plenty of pulp to use. We
have a conveyer attached to our cider press that carries the pulp to the
outside of our building and dumps the pulp into a manure spreader. We then
hook up the spreader to a tractor and spread it between our raspberry plant
rows. Rarely do we have to add additional supplement because the apple pulp
usually does the job. We repeat this process every time we make cider every
season.

A few weeks, or so, ago, someone proposed the hypothesis that
acid-loving plants don't need a low pH so long as sufficient nutrients are
abundantly available. I asked someone who should know as much as anyone
and
here is his reply:
I would tend to agree with the pH issue, except that the acid loving
plants
are not capable of taking up nutrients unless the soil pH is acidic.
I have seen a lot of blueberry plants fail because the pH was too high
even
though adequate nutrients were available for good plant health of other
plants. Aluminum sulfate should probably be avoided. Ammonium sulfate
as
a nitrogen source will help keep
the soil pH lower too.
Happy New Year!
