Avoid These Common Pitfalls
Not sure if a bulb is viable? Look for bulbs that are firm to the touch
Bulbs hate "wet feet" - never plant in areas with poor drainage or standing water
Planting when the soil temperature is too warm is the primary cause of stunted blooms
Road salt and de-icing compounds are harmful to bulbs - avoid areas where plowed snow accumulates
Crop rotation is key - don't plant the same type of bulb in the same spot year after year to protect against Rhizoctonia
Don't plant too shallow - it's essential that bulbs are planted at least 3 times their height into the soil
Plant bulbs firmly in the soil with their pointy end up and basal plate down - not all bulbs will right themselves underground
Avoid areas that do not receive at least half a day of sun
Plant away from invasive tree and perennial root systems that can strangle bulb roots & compete for limited water and nutrition
