Preheat oven to 450 ℉.
Using a cheese grater, grate your butter into a dish or plate. Once grated, place back in the freezer while you prep your other ingredients. (You want the butter to be super cold).
In a large bowl, combine the flour, baking powder, baking soda, and salt. Mix until combined well.
Add in your cold grated butter, using a fork to incorporate into the dry ingredients. Next, mix in your garlic scapes and cheddar.
Add in the buttermilk and combine. Scrape mixture onto a lightly floured surface and gently form into a thick rectangle. Fold one side over on top of the other, turn, and repeat.
Use a round cut out or scraper to form into 8 rectangles or circles (whichever you prefer). Place onto a parchment paper-lined sheet close together. Brush tops with melted butter. Sprinkle with salt.
If you don't want to bake all of them right now, at this point you can freeze them. Place biscuits on a tray, not touching, in the freezer for an hour. Then, transfer to a resealable plastic bag and freeze. When ready to eat, bake frozen biscuits same temp as below, but just a few minutes longer.
Bake 15 - 20 minutes or until fluffy and golden brown.
