I planted Roses for the hips. I did not do much research I just picked up what Raintree said grew good hips. Rosa Rugosa mostly the red and white one scabrosa and a Frau Dagmar.
I got them march 2016, 2017 they grew well and started to produce. 2018 I didn’t reduce the vines early enough they became overgrown. produced early but would rot. Later production didn’t have time to ripen.
Early 2019 I will reduce the vines down to the primary cane.
