    Pruning a tree tells it to grow more branches. If you cut off branch tips to contain spread, it will send up "water sprouts" which you don't want. It is better to cut a branch back to the trunk. Would removing all the lower branches (limbing it up) solve your problem? If not, then it sounds like you have a tree in the wrong location. Because it is a heavy sap bleeder, mid to late summer is the only time it should be pruned. Trimming of dead wood or small branches is less time sensitive. Bleeding sap equates to losing very important nutrients. It's worth having an arborist give you an opinion.

    A 15 gallon nursery pot will work for a tree that is 8 to 12 feet tall.

    Use a good quality commercial potting mix and add a slow release fertilizer to the soil mix. Do not over fertilize.

    Only harvest edible chestnut varieties for kitchen use. The horse chestnut looks similar but is poisonous. Horse chestnut husks have a smooth or spiny skin, while edible chestnut husks are completely covered in hairlike bristles.

    Spread a tarp or blanket under the chestnut tree when the nuts begin to drop from it in early fall. Cover the ground beneath the entire canopy to collect as many nuts as possible over the two- to four-week harvest window.

    Collect the fallen nuts every two days. The most mature nuts are full size with the husk already splitting open on its own.

    It's possible that these problems are caused by environmental stresses, such as extreme temperatures:

    The brown leaves could also be caused by a fungal disease called Horsechestnut Leaf Blotch:

    It seems this disease wouldn't be fatal to the tree by itself, but could weaken it and make it more susceptible to damage from other causes. You may want to consult an arborist or university extension agent in your area.

    You may be more spot on than you realize! the fire may have something to do with the leaves falling off, AND something to do with tricking the tree into feeling those warmer conditions associated with spring, or summer conditions. I don't believe that this is much of a concern, but if it does something strange in the springtime, we can revisit the situation, and find a solution from there.

    These trees are hardy through zones 3 to 8, and will be fine on their own, outside. However, if you wanted to ensure they make it through the winter, you can bring them in and care for them the first year that way.Here is an article with more information on the tree: https://www.gardeningknowhow.com/ornamental/trees/horse-chestnut/how-to-grow-a-horse-chestnut-tree.htm

    I would do a Google search for bare root trees. There are many growers that can ship directly to you.
    You can try Ebay also, just be sure to check the sellers reviews.
