I'm prepping to cut my seed potatoes but don't want to wait too long for them to scab over. I've noticed that some gardeners typically use lime or sulfur for this drying process. However, I don't have any lime or sulfur on hand, but I do have humic acid powder/granules. Is it possible to use humic acid for the same purpose? I think it should work since the goal is to help desiccate the cut surfaces and possibly manage pH levels.

Using sulfur is a common approach because it acts as an antifungal agent while also raising the pH, which helps prevent fungal issues. While humic acid might help with some aspects, it's not specifically antifungal like sulfur. It may not be as effective in preventing rot as sulfur or lime would be, so it's worth considering if you can get your hands on one of those instead. Just keep an eye on your potatoes after cutting!
Yeah, I agree! You definitely want something that helps keep the fungi at bay. If you can’t find lime or sulfur, just make sure to store your potatoes in a dry place to minimize the risk.
