Hey, yeah I put in lots of garlic and the stalks are very tall... Maybe too much nitrogen in the soil? I pulled one out yesterday and it was a good size. Maybe a little smaller than yours. Wish I'd done them all cause we have a torrential downpour today.... All day... Our 9 compost bags are saturated!😢 I hope the excessive rain doesn't ruin the garlic bulbs. Apparently here in Ontario Canada were getting the after effects of all your hurricane weather. Hope your garden recovers.😊❤🇨🇦🙏
