Proper spacing aka 'How many more can I fit in?'
I'm placing OGRs along the south side of my garage and down along the edge of the driveway. I planted a Great Maiden's Blush this spring and a Hansa and am now looking to fill in between. I've already ordered Ispahan. I have 19 feet between the two. How far from the GMB should I plant Ispahan? How many other roses can I get in there? One? Two? I'm thinking GMB, Ispahan, open space, open space, Hansa. Recommendations for additional OGRS to fill in? Should I put Ispahan next to GMB or next to Hansa?
Also, I have two Hansa next to each other. Is 4' apart good distance?
