Thanks for all the advices.
We planted 9 bushes, in the order of purple, light orange, deep red, yellow/pink, orange/red, yellow, hot pink, white, and orange color. Each are about 2 feet apart from each other & 1 foot apart from the block wall.
Since everybody had warned me about planting them well apart & I assume that means more than 2 ft. Unfortunately that's what we did (when I got home, hubby already digged the holes).. so I want to know what's the worst that could happen because of planting them too close to each other.
