Thank you it does help. I have Sweet 16, and Chestnut crabs still on the tree and because this is the first year for a some fruit I have already sacrificed a few trying to see if they are ready.
Chestnut is almost there, the seeds are half brown and they are getting less tart and sweeter. I see that Sweet 16 will be about two weeks later than my Chestnut.
I don’t want to pick the remaining apples till they are ready as they have been crossed with my Trailman and I don’t want to loose the seed.

That is handy, and here are a few more. They are a little bit hard to find from their homepage (they are under the “Growing Tips” section). They also have very detailed pollination charts.

Thanks for filling out the list - I didn’t even know it was there. I’m downloading the pear chart now.

Thanks. I’ve seen it before, but good to see it in-season and print up for reference.

I see this chart quoted a lot but I looked at three varieties and they are all listed differently than everywhere else I’ve looked.

Gala is listed as group 3 but these two sources list it as group 4

https://www.foodforestnursery.com/growing-guides/fruit-trees/apple-trees-growing-guide/apple-pollination-chart-3/

Crimson Crisp is listed as group 5 but it’s usually listed as group 3 in the former source and here: https://www.foodforestnursery.com/growing-guides/fruit-trees/apple-trees-growing-guide/apple-pollination-chart-3/

I only checked those two and Goldrush (group 4 vs 5) but they are all different. Either Grampa is wrong or the rest of the internet is.

Edit: Grampa’s chart also lists mid-season bloomers (group 3) as capable of pollinating both group 1 and group 5, which would effectively make half the apple varieties universal pollinators. There’s a note at the bottom that says neighboring groups can give better results but does not contradict the main chart.
