When you are over the hump as it relates to the approaching growing season, it's all down hill until those spring flowering bulbs start to poke their little heads out of your flower beds.
If you have experienced your spring flowering bulbs starting to rise above the soil surface early, don't worry. The best thing to do is actually nothing.
If you are in that plant survival mode when this happens, think twice. By trying to cover the new shoots up, you are doing them a disservice. The extra mulch will actually create a disease problem and might well do in your spring flowering bed.
Mother nature is unique, especially with plants poking their heads out of the soil during warm periods in the winter. They will adjust so go back inside and think good thoughts.
As for spring flowering bulbs, leave them alone, rake up the dead leaves from last year, apply an application of fertilizer around them in mid-March, and if you still have a few bulbs left over from last year for whatever reason, plant them when the ground isn't frozen. They probably won't flower this spring but at least you will have them alive in the ground for the next year.
Remember, the Paper White Narcissus, available at many lawn and garden centers now, can be forced to flower without having to give them a cold period. For Easter, plant them in pots indoors about 7-8 weeks before you want them to flower.
