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.
