loads of pots planted. how best to water in?

I've always found that a watering can (10 litre I think) with a coarse rose is best. It needs to be a coarse rose (larger holes) else the holes will block up with the carrier from the nematodes. I mix the entire solution up in a bucket first (as per the instructions on the pack), then fill up the watering can and start watering the pots.

can it be used later than november

Temperature and humidity are important to the success of these biological controls. Nematodes travel by slithering around the soil particles so the soil needs to be kept moist. If it is hot and dry they will either shrivel and die or hide away deep underground. (On the other hand they don't survive very waterlogged ground - they will actually drown within about 2 hours if placed in water). Likewise if the soil is freezing the nematodes will perish. Most beneficial nematodes will not survive a British winter outside and will need to be reapplied each year. (quote from: https://ladybirdplantcare.co.uk/nematodes.htm)
