Good Morning Pete,

Congratulations on achieving the plant patent for Niwot.

We purchased 5 plants last spring and have been very pleased with it. I 
am planning to rip out the old raspberry bed of which I don't remember 
the original variety and I suspect now is primarily under performing 
seedlings. I was under the impression that Niwot would set 2 crops, an 
early summer then late fall. Quite frankly it seems to be more ever 
bearing than a duel ripening season as we have been picking fruit now 
for 60 days with many new clusters forming. Many of the berries are 
actually dual (Siamese twin) with one being larger than the other. It is 
very vigorous and I need to increase the height of the top trellis wire 
to keep the cains off the ground. Presently the top wire is about 5 feet 
and I should add another one 2 feet higher.

Again, congratulations and my fruit breeding hat is off to you.
