Resurrecting an old post here. I've managed to start a few goji berries from seeds in the past month. I've moved them up to paper pots temporarily from a nursery 4-pack because I know their root growth is tremendous. Hopefully, I'll grow them on in 5-gallon buckets per some Peaceful Valley info I read so that I'll be able to keep them indoors their first winter. I made a mix for them of Pro-Mix premium, traction sand and perlite as I've read that they like good drainage. I have not fertilized them yet but will do so with a little fish emulsion. It's my understanding that they like a higher pH - above 7 - and I'm wondering what I can use as a source of calcium carbonate other than buying a whole bag of lime or whatever. I will test the pH first but want to have my info all lined up. Thanks!
