We love the selection of bulbs available from A.D.R. The variety is great, the quality is excellent and the price is fair. However, the best part of working with A.D.R is the customer service from Chris, Walter and all of the team. They go out of their way to make sure ours needs are met.

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
