Here in south Florida, I grow in 15 and 20 gallon containers. I use ProMix for my potting mix and amend with cow manure. You can also add French marigolds to the pot and also 1/2 cup or 1 cup of alfalfa pellets to the mix. It makes a big difference in my over all RKN infestation. Put thick plastic, like Marsha said under the pots does help as well. Make sure you use only french marigold and 100% alfalfa pellets..not store bought rabbit food. Alfalfa has triacontanol which is a growth stimulant and it's released in the soil like a steroid for your plants..RKN do NOT like this chemical. Use the entire marigold plant...leaves, stems and roots. I do this for all my tomatoes, peppers and okra, cucumbers in the spring.
