I planted some fresh pawpaw seeds last fall in my greenhouse. They haven't appeared yet so I'm wondering if they failed or if I'm impatient. For a timing reference, my figs have budded out and pushed 6+ inches of growth.
Same with mine, planted in March and came up in July. Also pawpaw can tolerate full sun so you don't need to grow them in shade. I really regret I planted all my seedlings in shade and they are growing so slowly.
Still not late for Pawpaws to sprout. Mine here on the Delmarva usually do not sprout above ground until late July or early August. They could very well have already sprouted underground forming a good taproot prior to emerging above ground, and making one to three leaves only, in their first season.
