Positioning Pecans for Optimal Pollination

    2 responses

ChantelleGrows starts with ...
Should Pecan 'Shoshonii' be planted upwind of 'Cheyenne' or the other way around?

I'm planting these two cultivars 20m apart on my Sydney property and I've been reading that one will be the primary pollinator of the other, so I'd like to maximise pollination by optimising the positioning.

Thanks for your help!

Hi Chantelle

As shown in the 'Pecan Pollination Chart' Shoshonii is the pollinator because its pollen shed significantly overlaps the pistil receptivity of your Cheyenne pecan. In my opinion based on the pollination chart Shoshonii the pollinator should be placed on the upwind site, and your Cheyenne should be on the receiving end (downwind) to maximize cross pollination. On the downside your Cheyenne pecan have a very limited chance to pollinate your Shoshonii because Shoshonii's pistil receptivity doesn't coincide with Cheyenne's pollen shedding times unless you plant a third variety (Owens or Pawnee) coinciding with Shoshonii's pistil receptivity with the 3rd cultivars' pollen shedding. If in doubt, please double check the pecan pollination chart.

Happy gardening :-)

Thanks Fruitilicious that’s helpful!

I can understand the pollination charts now with your info. For anyone else reading this who might find it helpful, here’s the link:
