I checked my two trees yesterday. One has a lot of insect damage. The one 100 yards away looks great.

I think I figured out the picture thing. I'm told this is indeed the early formation of a "bur"..... This is my first and my tree was planted in 2014 as a 3 gallon. Th etree has a few of these so hopefully at least one of them produces.

JB,
You need another tree to pollinate that bur. The work looking things (catkins) are what produces the pollen. If you have one from another tree drag it over the bur. It might work. There's a time frame window for pollinating but, I'm not sure when is best. If you don't have another tree then it most likely won't pollinate. Maybe less than 5% will self pollinate.

Planted in groups of 3.....another tree with catkins not 50 feet away. So I hope to be ok!

I heard from my father inlaw that the chestnuts I gave his friend a few years ago are doing well and were full of catkins and burs this year. He has a 20 year old chestnut that is very large so I'm hoping the trees were able to cross pollinate and he will have a crop large enough that I can get a few nuts.

I was out today and checked my trees and thought of the spacing question - so I checked. Mine are right at 25 feet apart. I also noticed my burrs seem to be growing as well - a bit bigger than a quarter at the moment. Anybody have any good advice on chestnut tree fertilizer? Getting a "taste" of actual chestnuts, has me looking to give them a kick in the pants!

Be careful on fertilizing them too late because they may produce a lot of new growth too late and lose it to dieback if they do t harden off fast enough. I'd wait until next spring

I'd wait until next spring Looking at my post - I see it could be read that I wanted to fertilize now. That's not the case. I actually meant come spring....not now. I want to get the tree to grow/mature faster more so now that I know some of them are producing burs now. I didn't mean fertilize them now to try to kick growth in the pants now......sorry, my post was a little misleading.

I had overwintered a few small Dunstans last winter. This one has grown over 3.5' this year. Others have grown close to 3'. I had them in shade and forgot about them so they might have done better.

My burrs are growing they are about the size of a ping-pong ball now. No insect damage thus far. I'm sort of excited to see them doing well. I know it's literally just a few, but they have to start somewhere.

I know it's literally just a few, but they have to start somewhere. I hope you have lots of chestnuts nuts this fall. The burs will grow regardless of whether they were pollinated. They'll keep getting larger until they break open or drop. They'll be around tennis ball size. If the winds were right and they were pollinated then you'll have 2-3 nuts per bur.

I have 1 that has burs, 5 were planted at the same time. A couple of those had some die back.

I'm watching them closely as these are my first burrs so I'm hopeful I actually get a nut or two. I'd be thrilled with just one to be honest. It would be my first and you have to start somewhere.
