I recently got some Bamboo, an Basket Willow and some other potted plants from Bamboo Plants Canada. Additionally last year I received some Korean Pine Nuts in pots, from Grimo Nut Nursery.
Unfortunately the Korean Pine failed to thrive. While in the instructions for the Korean Pine it said to take some soil from established pines and add it to the Korean Pines to get their mycorhizal mushrooms, I’m not aware of any pines around here with them, and don’t really feel comfortable digging around on public property to check if the pines have mycorhizal fungi. Not even sure how I would check.
The other plants I got from Bamboo Plants seem to be doing okay, however the bamboo was somewhat yellow, and it’s status seems to be degrading. The basket willow arrived in good condition, but it was rather small and seems my 18 month old decided to tear off most of the leaves.
While I had used mycorrhizal fungi from Bustan before, however checking their list of members, it turned out that the mycorhizal fungi from Gardener’s Pantry
had greater variety. And while the one from Bustan seems to be mostly geared for hydroponics, the gardener’s pantry one specifically mentions pine. It contains Glomus, Gigaspora, Paraglomus, Rhizopogon, Pisolithus, Laccaria, and Suillus;
I did some research and found the Bamboo can be colonized by endo-mycorhizae such as Glomus, Gigaspora, and Paraglomus. Wheras the Rhizopogon (edible), Laccaria (edible), Pisolithus and Suillus (Boletes), and is good for forming relationship with pine. Willows are one of those few plants that can form relationship with either ecto or endo mycorhizae, but it seems willows are mostly ecto-mycorhizal.
I found a list of various plants based on if they form endo or ecto mycorrhizal relationships.
In any case I ended up following the instructions, 1 teaspoon for 2 gallons of water. I dipped the potted plants in, fully saturating their roots. then planted them back, and watered them. I’ll try to get some pictures so can do before and after photos. hoping will see a difference within a few weeks.
