Optimal bulb planting depth, a crucial factor for successful flowering, refers to the distance from the top of the bulb to the soil surface. For instance, a daffodil bulb typically requires planting at a depth of approximately 6 inches, while a smaller crocus bulb might only need about 3 inches of soil covering it.
Correct planting depth significantly impacts bulb survival and flowering potential. Planting too shallow can expose bulbs to temperature fluctuations and drying, hindering root development. Conversely, planting too deep can delay emergence or even prevent flowering altogether. Historical horticultural practices have long emphasized the importance of appropriate depth, reflecting empirical observations of plant growth and performance.
