Rose of Sharon Spacing?
I have 9 3yr old seedlings I started from seed myself, seed was from a robin egg blue color. I also have 9 seedlings maybe 2 yrs from somebody elses yard, unsure of color. I wanted to put them along my fence in back to form a privacy hedge over time. They will be getting about 6-8 hours direct sun. All of them are only single sticks with leaves. I was thinking grouping them into 3 plants forming a triangle, each plant a foot apart and each group 5 feet apart? Does this make sense?
