There are several reasons we do not use fertilizer, at all, on the farm or for the nursery. Fertilizer causes fast growth which leads to incorporation of air into the woody structure. This leads to weaker woods which will not be able to withstand climate change freak weather events.
Beyond plastic pollution in our oceans there is international scientific evidence spotlighting the degradation of our oceans concerning lower concentration levels of oxygen. Climate change and increasing temperatures is one culprit.
The second culprit is fertilizer runoff. Don’t ever think that what we do in Ontario does not affect our oceans. Everything drains into the Great Lakes that leads to our oceans.
