I am a landscape designer and have been purchasing 1000's of spring flowering bulbs from A.D.R. Bulbs for 100's of clients in the last 20 years. The bulbs have always been of top quality and if there were any problems, they have been quick to rectify. My orders are often complicated with many varieties and different amounts and they have always filled and delivered everything on time with the best customer care and attention to detail. The pictures in their catalog and website are beautiful. I have visited their facility in NY and was impressed with all their handling equipment and organization. I would highly recommend A.D.R. Bulbs to anyone in the wholesale trade who wants to purchase quality bulbs and work with genuinely nice people.

Most bulbs can tolerate temperatures between 38 and 70 F
Protect from heat, frost and strong sunlight
Pre-cooled bulbs for the South must be planted immediately
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
