Wow! I envy your weather. About 3 C here now. No real sun in over a month. I would suggest some serious pruning. The smoother the bottom...the better the head.
The sun is really good, but it's been rather wet the last week. Gonna put some more manure down tomorrow, it'll need it.
Several stakes around and I think i'll be running a couple lines of wire, still haven't decided.
Generally a little different pruning outdoors imoe. I clean and srtip the inside and leave the outside, to take advantage of all the sun.
Anything growing inward toward the trunk, or scragginess which might encourage pest and disease gets chopped.
I leave anything healthy and the popcorn. I like making butter and hash with it.
I'll fully admit indoors is a different kettle of fish.
