Rhapsody - The Root Knot Nematodes (RKN) are mostly found in FL soil. They attack the root system of plants that don't have a resistance to them. Nasty little things! All my brugs are now in containers once again. They do just fine there, too.
What size container do you use? I use the 18 gallon plastic storage bins. I drill holes in the sides of the bins on the lower edge near the bottom and they are ready to go after adding potting mix!
