When deciding where to plant your roses, keep the sun in mind.
Roses do best in plenty of direct sunlight, at least 5 to 6 hours a day, if possible. The sun in the morning is the most important because it helps prevent diseases by drying the leaves of your roses.
If your roses are not getting enough sun, they may display sub-par blooms, weaken and become more susceptible to parasites and diseases. Inadequate sun will make it less overwintering less likely.
The more sun, the more flowers. When deciding where to plant, keep in mind that the angle of the sun changes throughout the season. Try and choose an area that offers the most sun the year-round.
