There is a difference in getting pecan trees to live and getting pecan trees to produce pecans.
Then the squirrels eat them.

Ya, but when did they set? My guess would be 14 months before they matured. Thatās no plus.
Mexico has areas that never freeze and never get too hot or too cold so pecans could hold leaves right thru winter. That wonāt happen in the US.

Iām going on memory, but this tree was in northern MX so was going through typical fall defoliation. I suspect it made small nuts and mostly matured them with overwintered reserves from the roots.

Iām curious. How do folks in northern Germany pronounce āpecansā? Spain? Italy?
And other faraway places such as Kansas, New York and Kentucky?
I fear that if I call up these folks in Austria or elsewhere and ask about their āPecuunsā they may not understand what Iām asking!

Someone did a study of dialects in the U.S. and came up with about 60 regional variants. Your region has some unique usage such as āhitā. I often heard āhit donāt matter one bit to meā from my grandmother who grew up in Grundy county in Paynes cove which is near Pelham. Just saying, there are a few dozen ways to pronounce pecan in the U.S. from peacahn, peeKAHN, pican, picahn, puckan, etc.

PekannĆ¼sse in German
The climates in Europe are pretty odd compared to usa. most similar to west coast usa i guess with the oceanic climate.
I have a good amount of pecans planted. some northern seedlings, some grafted, some totally wrong seedlings that iāll need to graftā¦ or just enjoy the big trees if they never produceā¦ Seems like warren 346 is the bet betā¦
Any suggested sources for tables showing pollination partners for early cultivars?
from this Austrian nurseryā¦ but, they do have a warmer climate thereā¦
(Pekannuss ā Baum- und Rebschule Schreiber)
(general questions not all directed at tennessean)
I also agree with whoever said maybe it is better to grow hazelnuts in german climate. We can grow nice sized european hazelnuts compared to americansā¦

If you have excel, pull the pollination spreadsheet. You may have to paste the link into your browser.

In Northern Italy (at least in my area), pecans are virtually unknown

Can you describe your climate Exmil? Particularly need highest summer temperature,frost free days, winter length. I suspect you could grow ultra northern pecans such as Warren 346.

They donāt publish info like that here, but Iāve been here a long time so I can go by memory.
Highest temp in summer is about 38C but most of July and Aug are about 32-36C. Frost free is pretty much mid March-mid November. We havenāt even been close to frost yet but this weekend there are supposed to be two nights at 2C. Coldest is about -6C but normally -4C to 0 in December and January.
Dec and Jan are the coldest months and it warms up in March. We get plenty of chill hours but no drastically cold weather. So itās zone 9A because of the lack of cold but the heat is pretty much limited to July and August

I canāt help but to be curious. What is the elevation at your location? Iām thinking that northern Italy would be mostly mountains. The elevation here is around 360 feet, which puts it at basically at sea level as far as pecan trees are concerned. Of course, youāre probably on the metric system. Then again at zone 9A you may be coastal.

Iām at 65 feet. I have the Alps to the North and the coast is 1 hour drive to the South. I think the mountains protect us from the cold to the North

Why do pecan trees consider 360 feet to be sea level?
2 Likes
Because at 360 feet the difference in temperature from sea level the elevation increase has no effect on the pecan trees. The cold mountainous air which is over 500 miles away canāt get to us. In fact, at 360 feet at my location, we are considered to be Mississippi river delta land even though it is a very slightly rolling landscape. This is native pecan land.
I think the determining factor as to how the well pecans will do at your location is the soil. Mine is mostly a clay type. Iām not an expert on soils but because wild walnut trees were growing there, I concluded that the pecans would do okay. They are in the same family of trees. Now the squirrels can choose between the walnuts and the pecans!

I have clay soil also. Blueberries canāt grow in the soil here but veggies do great so I assume my ph is in the 7 range or so

Based on my climate, what are your suggestions for pecans to plant?

Same as above, Warren 346, Lucas, and Campbell NC4. Warren 346 is very high probability of maturing nuts even with cool summers. A few more could work such as Witte. Getting them on a northern rootstock such as Major would be needed.

It should download onto your computer automatically. If not, copy and paste the url to your browser and see if it works. If it pulls an empty file, copy and paste should get the full 1.3 mb file.
