Hello,

I also found this web page with computer based pollination software. There is a link to seek permission to use it for research pyrposes at the bottom.

Hello,

I am no botonist either... What about an end run...

What is the spacing of crab apples in commercial apple orchards for
pollination? This may be an easier answer to find, then it is just a
matter of size and scale.

It all circulates around the insects, their foraging habits, and the
weather.

straight. :-)

I've been running into a number of references recently (NAFEX, Internet,
etc.) that suggest that the standard suggestion of a 1 male to 8 females
pollination ratio for hardier actinidia (arguta and kolomikta) may be
way low of optimal, especially for the home grower. Arguments are that
actinidia is generally a weak insect attractor, that males are generally
weak growers, and that wind pollination is a significant factor.

This suggests that a useful planting strategy for the home grower is to
(1) plant a much higher male-female ratio in close proximity to each
other, and (2) to consider the prevailing wind direction. So planting
co-located/entwined male-female pairs should help. If a lower
male-female ratio is used, then planting the males upwind may be useful.

A year or so ago I asked whether grafting male scions onto female vines
would help with pollination and several knowledgeable Nafexers thought
that it made sense, although they were cautious about how well the
grafts would do in zone 5 weather. I haven't tried the grafting yet, but
I'm sure I'll get around to it next spring. Anybody have experience
trying summer budding?

On a related note, my arguta vines have a decent crop this spring. My
two male vines flowered for the first time (5 years and perhaps some
injudicious pruning after planting), but I also did hand pollination
with deliciosa pollen I got from a pollen-supplier in California. My 5-
and 4-year old daughters helped pollinate the low flowers with Q-tips,
but got off task after several minutes and started a new form of tag
that involves running around trying to pollinate each other with the
Q-tips. Me: "No, I don't have much pollen and I'm not going to give you
any more for your Q-tip unless you start putting it on the flowers, not
each other." :-)
