Special notes: Grandma's Yellow rose is hardy through most of the state, but may need some protection in USDA hardiness zone 6; if own root plants are grown, new shoots should sprout from the crown after severely cold winters; it is disease tolerant, but can be attacked by black spot during wet periods mainly in the spring and fall; a few fungicide applications in the spring or during long wet periods will control the disease, but plants tolerate the disease well by readily producing new growth after defoliation; does best with regular watering and fertilization
