Little Chestnut Help Please!

[CuivreDog]

I have a friend over on the MO deer board that sent me these pics of some chestnuts he's growing in his greenhouse and asked me for some help. Unfortunately I've never seen this problem in the years I've grown them. Any ideas on what is causing his issue?

Could be many things but most likely too much moisture. Chestnuts don’t like wet feet.

They’ll also do this if you let them get too dry. Part of the leaf will turn brown and die because it didn’t get enough water.

So more than likely what ever it is has something to do with water. Either too much or not enough.

NPK imbalance, water Ph issues, and chlorinated tap water may be a contributing factors as well. Also, planting medium could be the issue. In my experience Chestnuts and Oaks won’t do well in typical potting soil. They like a well soils that can breathe. I’ve had good luck with Promix brands. Similar to what Matt said, wet feet.

One of the hardest things about growing in a greenhouse is regulating the heat in spring. I took my greenhouse down after burning up plants on a hot spring day. Just last week it got up to 90 degrees here in OKlahoma. It should have been @65. That could be what’s happening there. If the greenhouse isn’t monitored for temp and ventilated well, you can get leaf scorch but the soil is still moist. So you water again and then create another problem. Yes growing seedlings is challenging, just like farming, every year presents a new problem. Like the other posts said it could be one or all of the issues stated above. Or it could have just gotten too hot for new leaves to withstand.

Hey CD I found my way on this forum thanks for this thread . I’ve cut back on water and it seems to help .
I believe maybe my cheap soil I bought may have something to do with my problem. Next year I’m ordering promix .

Thanks for your input sir . This is my third year using this hot house . And I agree that on hot days definitely need to open up for ventilation . I also staple a shade cloth to the ceiling once spring temps get up .

But this year has been a cold spring with few sunny days . I believe this is why I got tricked . I usually water every three days in the house . I’m summer once trees are hardened off I move them out to pallets.
Couple pics of the greenhouse I built

Ants are really working the tops of my chestnuts trees over. The trees are around 5’ tall. Will this really hamper their growth? I’m considering spraying them with seven. The leaves look like skeletons without any flesh, if that makes any sense. I don’t see other insects on them, just the ants.

Hit em with Sevn. It won’t hurt the trees.
