Good morning, I planted 40 large football Portuguese laurel bushes to make a hedge back in October and at the time I added some rootgrow mycorrhizal fungus granules to the holes I was planting in. I was in a rush as I had to plant all in one day as we were going away the next day. The bucket of granules came with an additional sachet of white sugar-like grains but in my haste I didn’t use them and now I don’t know what they are for! Can anyone tell me? I was wondering if they were to make a dipping gel with? I’m planting some bare root box hedging soon, so I thought I could maybe use the stuff then. Thanks!
