Success with Roses in Containers/East-facing
I have had years of success in growing and blooming Roses on my balcony in containers. They get full morning sun up to about 1:30PM and do splendidly each year.
Along with Begonias and Petunias, lilies, morning glories
I find container gardening to be great.
I do grow herbs, but they are placed at the far end of the balcony when they only get "dabbled sunlight", or they burn up and die.
