Answer: Some of the older shrub rose varieties tend to normally have a major flush of blooms in the spring possibly followed by a scattering of blooms later in the season, but many bloom only once. Hybrid tea roses will bloom repeatedly during the season if they are kept healthy, otherwise may provide an early flush and then struggle for the rest of the season. Roses need full sun, good air circulation, ample water and good soil in order to do their best. They may also suffer from pest or disease problems which can cause them to defoliate. Finally, to encourage repeat bloom, flowers should be removed as they fade.
