Valerian for Late Frost Protection or Compost Preparations

BD #507 (Valeriana officinalis)


For Late Frost Protection

"Valerian surrounds the plant life with a warm mantle.” – Manfred Klett

Fermented Valerian blossoms (Valeriana officinalis), BD# 507 has been shown to protect blossoming fruiting trees and plants from late frost in the spring as well as from early frost in the fall.

In his landmark work, Principles of Biodynamic Spray and Compost Preparations, Manfred Klett explains that the diluted juice of valerian has the faculty to create a sheath of warmth wherever it is sprayed.

Directions: Spray in the evening of predicted frost and again early in the morning for heavy frost. One unit (21 drops) stirred in 3 gallons of warm water for 15 minutes will treat up to an acre.  A partial unit may be used for smaller area.

For Compost Preparations

BD #507, which is also included in the Biodynamic Compost Set, will help to stimulate compost so that phosphorus components will be properly used by the soil.

DirectionsUse in conjunction with the other preparations in the compost set.
