Your tulips should be in the ground now, and small bulbs such as crocus, snowdrops, and grape hyacinth should be going into the ground by mid-month. Hold off planting daffodils until later in the month. To keep squirrels and other varmints from digging up and eating your bulbs, dust them with lime as you put them into the ground, and then add a layer of lime on top of the planted area. The lime interferes with smelling the bulbs, and is an important in ‘sweetening’ the soil for these plants that come from a part of the world with much less acidic soil. If you have very aggressive rodents, add hot pepper or chili powder to bulb coating.
