Orange glow knock out roses

The roses are lovely, growing very well, but my only problem is the bugs that love to eat the leaves, so I’m using seven on them and it is working, but leaves that white powder, but they are still doing well.

Fast Growing Trees Plant ExpertHi Judith, thank you for sharing your experience and for caring so well for your rose. It is great to hear that the treatment you’re using is helping, even with the residual powder. If you'd like, we are happy to suggest additional options that are gentle on your plant yet effective against pests or ways to rehydrate the leaves if the dust becomes too noticeable. Just reach out anytime.

Very non-experienced gardener

I ordered 2 orange glow rose bushes. They weren't in very good shape when they arrived, no fault of the company. The boxes were bent, broken, and ripped. This is my first time doing the flower gardening thing, so I just sent them a quick message and photos. They gave me some tips and they are thriving! Absolutely beautiful!!!!

Orange Glow rose

It arrived in good condition and has beautiful flowers and color, the flowers are small blooms about 1-1. 5 “ in diameter. It is doing well and looks good where I planted it.
