What have you planted too much of? Too little?
I am trying out many different plants this year. I am interested in hearing which plants you have overplanted in the past and which ones you have underplanted. I am not as interested if you underplanted say lilies just because you couldn't afford too as I am in which plants you under or over estimated their production and usefulness. I am trying love lies bleeding as well as 'hot biscuits' so would especially love comments on the amounts you planted of those. This is going to be another learning year for me. However, I am planning on the best trial run I can muster. Thanks in advance for all the interesting replies.
