Plant Answer Line Question
Many of my crocus and daffodils (especially crocus) didn't flower this year. They don't seem to be in need of separating - none of them have been in the ground for over 3 years and I don't think I overfertilized. Otherwise they seem quite healthy. What might be the problem?
The most common reasons that hardy bulbs like crocus and daffodils fail to flower are these:
1. Planting location: they need to be planted in full sun.

2. Drainage or heat: spring flowering bulbs planted in poorly drained soil or too near a heated basement (where heat from the structure warms the soil and interferes with the bulbs' necessary cold treatment) will rot or simply fail to flower.

3. Fertilization: high nitrogen fertilizers encourage lush green growth and discourage flowering.
