Hi all. I'm getting steadily more and more excited with the garden at the moment. My fritallaries are starting to open and my hostas are just starting to show signs of life. I have also noticed my first tulip has opened this morning so the weather is gradually improving ! But speaking of tulips I have various clumps around the garden that are just sprouting leaves and no flower head. How can I cure this as I seem to buy new tulips every year and never normally get more than two showings from them.
