Never Plant Flower Bulbs in Exterior Containers or Raised Beds

Flower bulbs should never be planted in outdoor containers, window boxes or raised beds where bulbs experience temperature spiking and repeated cycles of freezing and thawing. This results in root growth failure, root system destruction, frozen bulbs and/or bulb rot from poor water drainage. This causes stunted plant growth and few, if any, flowers.

Flower bulbs must have a consistent cold winter temperature underground, with good water drainage, in order to produce a mature root system that will permit foliage growth and flower production in the spring.

All flower bulbs are best left in the ground to regenerate.
