Last year I planted Jerusalem artichokes in pots for the first time. I am growing as many root knot nematode susceptible plants in pots as possible over 2 years to eradicate the spread of this pest in my vegetable garden. I planted single corms in 10 liter pots and today harvested the first one. They have been situated under a tree so received 50-60% shade. The pot produced 540 grams of tubers. Has anyone else grown JA in pots. I am thinking that if the other 4 pots have produced as well i will replant in ten, 10 litre pots as a crop as the amount produced is a good size for my family meals and 10 serves would meet my needs.
I use a fairly standard potting mix made from composted wood-chip, composted chicken and cow manure and around 10% worm castings and 20% sand/ and or gravel. For acidic plants like blueberries I use 10% Black Soldier Fly castings and pine bark mulch. Sometimes i add perlite or water saving beads to improve water retention.
Mine have only recently shown themselves in my garden. Just starting to grow.
Pat can you please tell me where to buy the Black Soldier Fly Castings? Or do you bred your own and if so how do I set up to do this?
