What happens if bulbs are not planted deep enough?Updated 8 months ago

Most bulbs should be planted 2-3 times their own height. Bulbs that are too shallow can often fail to perform as the bulb does not have sufficient distance from the top of the bulb to the surface of the soil to support the above ground parts of the flower. Nutrient uptake can be restricted as the roots are not deep enough in the soil and they may be prone to drought as the top 10cm of the soil tends to be dry.
