I am getting ready to start some seedlings in the greenhouse in the next couple weeks, so I bought some seed starting mix from Mike Lombard at Ideal Compost here in Peterborough. He and his family offer high quality potting soils, compost, and mulch for gardens in the Monadnock Region. We are so fortunate to have this local resource of high quality, organic products. However, they are not biodynamic.

After picking up my seed starting mix from Mike, I was visiting with Anthony Graham, who was the lead biodynamic gardener at the Temple-Wilton Community Farm since it was founded in 1985. (It is one of the nation’s first CSAs. ) He is mentoring my husband, Robin, and me as we are new to greenhouse growing. While we talked, it occurred to me that I should put the biodynamic compost preparations in the potting soil. I asked Anthony if he thought that was a good idea, or if I should simply use the Biodynamic Compound Preparation (which has the compost preparations in it). He said, “Why not do both?”.

I have decided that I will do an experiment. I plan to start some basil seeds at the same time in four ways:

  • One group will be planted in the seed starting mix with no biodynamic additives. 
  • One will have seed starting mix with the biodynamic compost preparations put it. 
  • One will have seed starting mix with the biodynamic compost preparations and will be sprinkled with the Biodynamic Compound Preparation.
  • One will only be sprinkled with the Biodynamic Compound Preparation.

I will plant them all at the same time. They will grow side by side, getting the same amount of sun and water. I look forward to comparing the seed germinations times, the seedlings growth over time and the quality of the plants.

Stay tuned for a report later this spring!
