Reducing needle size Larch

Can someone please provide me some information on how to reduce needle size on Larches.

is it to do with soil mix, watering and feedings?

if your trying to reduce needle size to show the tree let the tree get root bound like don't repot it a year or two at max past the time you usually repot then don't start to fertilize till the buds push green and the green is fully grown. nick lenz has also talked about when he shows a larch he would defoliate the tree. he talks about it in his book and ive asked him in the past about that technique hopefully this helps

My larch needles are super long right now. I imagine its because its in a large nursery can, gets plenty of water, and fertilizer. If its just in a growing out stage shouldn't be a big deal.
