Grafted pawpaw died - replace it or just let the rootstock grow?
Last fall I planted a pair of pawpaw's I got from One Green World, Mango and Taytwo. Over the summer we had some very hot and sunny days after a prolonged cool and cloudy spring, the shade protection I put up was blown off and the Mango got toasted. The leaves all crisped up and fell off and when I saw growth again it was all coming from below the graft. I know I need a second pawpaw for pollination, and that seedlings can have good fruit. I'm wondering if I should just let it be and take my changes with the rootstock, or if I should go ahead and order a new tree to replace the grafted one that died.
If I decide to get a new tree I'll go with a different variety, since the Taytwo weathered the sun just fine I'm thinking a second one that could handle the heat would be nice. Any recommendations for a tasty pawpaw that is tolerant of sun and heat?
