Roses require considerable light to be able to flower. Their flowering ability is reduced in direct proportion to reduced light.

Light can mean either intensive light on shorter days, or more diffuse light as found on long days under an overcast sky.

To flower freely, roses require direct light for about five hours in the morning when planted east of a building, or in the afternoon when planted west of a building.

In situations with less than four hours of direct light, fewer or no flowers will be produced and the foliage becomes soft and susceptible to diseases.
