There are great charts listing the best matches between the different Type 1 and Type 2 Pecan cultivar varieties, but does anyone know what works well to cross pollinate a seedling of the non-cultivar carya illinoinensis Hardy Northern Pecan? Thank you so much for any much needed education you can give me! Smith Benedikt, from outside Cincinnati Ohio (zone 6A)
good crosspollinator for Northern Hardy Pecan (not a cultivar)
What would work well is ANOTHER seedling of Carya illinoinensis. If you purchased (or plan to) a seedling already, then get another seedling from the same vendor.
What you want is plants that are not identical, but have overlapping bloom time, so that the separate plants can cross-pollinate. Pecans (and many nut trees) are poor self-pollinators.
