In reality, roots die when flowering starts. To provide the maximum amount of nutrition, it is best to fertilize in early spring, when plants are just starting to come out of the ground. Similarly, there is some confusion as to the best fertilizer to use. Organic fertilizers, such as bone meal and blood meal, work well. Although they do not supply high levels of nutrients, they are safe and easy to use.
Commercial fertilizers are easily accessible and cost less per pound.
Apply it at the rate of 1 pound of nitrogen per 100 square feet of flower bed. Be sure to select a fertilizer that does not contain other chemicals, such as pre-emergent herbicides. Spring blooming bulbs are a wonderful way to welcome a new gardening season. And with the warmer temperatures comes that long-awaited spring display. Even though the night temperatures are falling below freezing, do not cover the plants as they begin to poke their curious heads through the soil.
