I plan on planning a Chinese Chestnut and a Hardy Pecan tree on my land this
spring. Each needs a pollinator to bear nuts. Do I need two of each, or will
they pollinate each other? I also have 5 Apple, 2 Pear, and a Hickory nut
tree on my land that bears fruit and nuts, will these serve as pollinators
for the new trees. I don't know any thing about gardening or planting tree.
Thanks for any advice or information.
PS. I live in Zone 5/6 in WV. The zone line for 5 and 6 are very close to
about where I live, so I can't really say if I'm in zone 5 or 6.
Pecan trees are monoecious, that is, the male (catkin) and female
flowers are borne separately at different locations on the same tree.
However, the ripening of male and female flowers on a single tree has
very little, if any, overlap. If your pecan tree has female flowers
that ripen early you will need to obtain a different cultivar that has
early ripening male flowers to obtain cross-pollination.
Chinese chestnut is basically the same.
Both are wind pollinated.
To email, remove the "obvious" from my address.
Actually, there is a chance that a hickory might help pollinate a pecan.
They are closely related and there are hybrids between the two.
With wind pollinated trees (apples and pears need insects to get
pollinated), another tree doesn't have to exist on your own property.
The pollen is very fine and can travel a long way. If there are other
pecans and other chestnuts in the area, you should be OK.
My parents have a single Chinese Chestnut tree in the back yard. They
have no idea where the next closest chestnut might be, yet they get a
good crop of nuts almost every year.
