Spacing of hybrin tea roses?
Newbie question. When I read that a specific rose should be spaced "x" feet or inches apart, does that mean from base-to-base or from what will be the outer edge of the mature bush. For example, one HT specifies it will grow to 3 feet wide; the adjacent one will be, let say, 4 feet wide. How far apart should the centers of the planting holes be? Thanks for the advice.
