I wanted to start Chestnuts for deer and possible roasting. And I need two for pollination. (Auburn)

We lived in Europe and loved to eat hot chestnuts! We hope these will thrive at our house. The trees are also very beautiful.

is it resistant to chestnut disease like american chestnut blight?
Fred D on Oct 16, 2016
BEST ANSWER: Colossal is an American chestnut, which is not blight-resistant. Here is a link to a Chinese Chestnut, which is resistant:http://www.starkbros.com/products/nut-trees/chestnut-trees/chinese-chestnut
Can I plant 2 of these to pollinate each other?
Dianne V on Jan 9, 2019
BEST ANSWER: No, this tree is pollen-sterile, meaning it can't even pollinate another tree. You need at least two seedlings or another chestnut variety to pollinate Colossal.
My zip code (95959) is for Nevada City, the origin of the tree. Yet you say that the tree is incompatible with my zone. How can that be???
virtualrick on Apr 25, 2017
BEST ANSWER: It might be that your zone was updated to 9A when the USDA revamped their zone map and data. Since 9A is a cooler part of a zone 9, and fairly similar to a zone 8B, then you should still be able to grow this variety successfully there, especially since it originated from your location.

Alow to bear but a beautiful tree
I planted a Stark Bros. Colossal chestnut tree and recommended pollinator 5 years ago. Slow growing, but required no care other than mild pruning. Pollinator put out catkins at year 4, and Colossal produced its first burr (3 chestnuts) this year. Think we’re gonna be alright!

growing well
Have had this in the ground and all is well. Plant arrived happy and healthy and is doing well through this Spring. Had to cage them as the deer will browse and horn them. Hopefully in a few years it will be bearing well. Just like my other trees from Stark. Have tried bare root trees from other vendors with mixed success, these already rooted and in soil are doing better and will take at least one less year to bear.

Looks good so far
My trees arrived in good condition and were planted the day they arrived. They are now in their second year and appear to still be healthy and growing. I have an older Chestnut tree that produces lots of nuts each year which is why I bought two more to replace two English Walnut trees that did not produce nuts after 17 years. I live in Southern Illinois.

Bare root
I discovered through this transaction that I will not buy bare root trees ever again. The mortality rate was high even though we potted in miracle grow and each tree was on it’s own drip emitter... to no avail
