I wondered what happened to 100 red tulips I had planted on a huge gorgeous slope, with blue hydrangea in back of them...oh so lovely that 1st year...yes I saw "something" dug some up (squirrels I think) but the following years, the ones remaining would shoot up leaves, then nothing, no blooms. Each year there were less & less. I dug up what leaf shoots popped up last year & moved them to 1 smaller spot & fertilized the soil. I got 10 Tulip blooms this year. I guess they need more attention & nourishment? Not at all like Daffodils...man the Dafs are doing fantastic, even multiplied so I had to dig, separate & have more areas of them. Go figure. Tulips are pretty but I do not have that kind of time to be fooling with them, sorry Tulips, I leave you to the Garden Society, they plant a huge area for the town of Lewes every year. Now I know why...they just aren't so great at coming back reliably.
