Nematodes
Biological controls are safe and effective
1 Follow the instructions carefully. Start by immersing the nematode sachet in the required amount of water.
2 Stir the mix for the allotted time until the nematodes are dispersed.
3 Pour the nematode water onto affected pots at the recommended levels, after you have already dampened the compost.
4 You can dispose of the spent nematodes safely on the compost heap or in the dustbin.
