Sara, no. Not together. Provado will kill nematodes
nematodes can be used from spring to prob mid September but then are useless.
Provado can be used in late autumn and winter..
i use both though....if heucheras and the like look poorly in the cold season I will use provado to kill weevils then......the grubs in the soil. By the time spring comes around the effect of Provado has passed.
Ideally, nematodes used as a routine is good but in reality they are not always practical.
i think weevils' life cycles can be halted after a year or two of either treatment so I find now weevis are not such a problem
