I can answer both questions! Both potato onions and shallots splay out soon after they do their big division. They go from upright to looking like an upside-down umbrella, but the foliage goes on working, increasing the size of the bulbs. It looks messy but you should tolerate the visual disarray until the plants really start dying back. In my experience, a spell of dry weather in midsummer is the best time to plan the harvest. Your latitude may affect maturation time, but I would think you have at least six weeks to go, maybe more.

Okay, planatus. thank you! Your description is exactly what is happening. I will definitely wait longer.
