Rose Bush FAQs
Where Is The Best Place To Plant Rose Bushes?
Roses need a protected location, and prefer full sun, favoring the drying power of the morning sun. They flower best in at least 6 hours of direct sunlight a day. Choose a location in good, enriched soil that drains well and has good air circulation.
What Is The Best Month to Plant Roses?
You can plant Roses any time if you are able to provide enough consistent moisture and attention. While there is not a specific month that is best, generally because it changes with temperatures, climate and growing zone. However, the easiest times of the year to get Rose bushes established in your landscape are in spring after the last frost date, and in fall about 4-6 weeks before the first frost.
Do Roses Come Back Every Year?
Rose bushes are deciduous woody perennial shrubs and will return bigger and better each year.
