First time growing potatoes and they are exploding!

Decided to go all in this year and try to learn how to grow potatoes. I have a few methods going; vertical stacks with layered potatoes, the bucket method, and just regular in ground planting. I planted all of these the last week of March and the first week of april which was a gamble but I think it paid off as there were no late frosts. All of the planted potatoes got the same organic vegetable soil mix (Scott's? I'm unsure) as well as a heaping handful of mushroom manure. I layered them up as nicely as I could and separated the layers with straw. The straw had a bit of barley seed or something in it which sprouted and then died back pretty quickly.

For the vertical stacks and the buckets, I made the mistake of not labelling what I planted lol..They are a mix of kennebec, Yukon gold, norland, warba, and red Cristina. I am almost certain that the left stack is exclusively kennebec, with the right stack being a mix of the rest. The buckets I believe to be kennebec but they also could be Yukon gold, guess we will have to see!

I became obsessed with the explosion of growth recently out of the left stack and the buckets that I planted three more buckets but this time I used a pink fingerling variety. Please let me know of your potato growing experiences and let me know if there's something I can improve on or just educate me on why I need to be prepared to be disappointed lol. I am having a lot of fun learning the ways of the tubers!
