If you are interested in comfrey as a companion plant, please join in on this conversation!
A group of us have planted comfrey and are recording our observations to see what benefits it may have for growing fruit and nut trees/vines/shrubs. There are already a handful of studies demonstrating benefits in other climates (which are referenced in our research proposal) so the goal is mainly to see what benefits can be observed on farms in different parts of Ontario.
We want to know if you have tried planting comfrey as a companion plant? If so, what was your set up and what benefits did you observe in your fruit/nut trees?
We are expecting some of the benefits to be longer term, so for those who have had comfrey a long time, how long did it take to notice a difference? One hypothesis is that the difference might be measurable after three years through a foliar test (leaf tissue) showing higher levels of potassium uptake in fruiting plants next to comfrey.
If you’d like to join in and plant some comfrey, or add in your existing comfrey observations, please let us know here.
