Im not sure nematodes would work for this. I believe theyre to fight insects. But if they work against fungal/bacterial infections then yea i dont see why that wouldnt work.
Yes that would work as well. A combination would be ok too.
Neither of which will eradicate the problem but will help it fight the infection long enough to flower and die.
A beneficial microbe should be added weekly with a food source into this garden. For example, the lactoserum, EME, IMO, kombucha, whatever can be used in your arsenal.
To solve the problem faster than starting these cultures would, go to the pharmacy and get a bottle of probiotic tablets.
Use one-two tablets per gallon of water with 1-2T molasses. Disolve and aerate it and replace your watering with this once a week. So, like a 5gal pail would need 5-10tablets and 1/3 - 2/3c of molasses. The neem can be added to this as well.
