Pink tulip varieties always boom deep coral
Both my varieties of pink tulip bloom a deep coral colour. Why? Is there something in my soil that is turning them this colour? Is there some way to amend the soil so the colour is more true? I've used a nice common clear pink tulip called "pink impression" and another called "christmas dream" both come out deep shades of coral and my "angelique" is not bad but also comes out darker than it should. Ideas?
