Having started a wormery three years ago, I now have some 3 year old vermicompost to use.
Last year I put a spoonful of 2 year old material into my tomato pots – they seemed to like it.
This year, I am trying to grow carrots for show in polypots, so I decided to see if vermicompost aided germination or not.
I filled two polypots with standard garden centre MPC, watered it to saturation, then I spread a very thin layer of vermicompost on top. I placed 3 Sweet Candle seeds in each of 12 locations (8 around the outside in a ring and four equally spaced inside). After a thin covering with vermicompost and a quick water, the two bags were left in my lean-to propagation module on the bottom shelf.
With seedlings emerging after 14-17 days, the bags came out to live in the open and I could score the outcome.
Of 72 seeds sown, >60 germinated into healthy plants, a rate of over 85%.
I have often read about the great germination qualities of vermicompost.
Now I have seen it in action…..
