Narcissus depth, roman hyacinth not blooming

Daffodils are very good at sorting their own depth, and don't usually grow
with the bulb exposed.
Bulbs planted very shallow tend to divide into lots of smaller, non
flowering plants. Deeper planting encourages fewer bigger bulbs.
However, extreme conditions can cause bulbs to grow deeper or shallower
naturally.

For the hyacinths, feeding will be beneficial if the soil is poor. If the
leaves are a rich, dark green, they probably won't need fertilizer. Best to
keep nitrogen levels fairly low. Fertilizer for fruit or flowers, such as
tomatoes or roses is suitable.
