Derbyshire,
United Kingdom 
when is the optimum time to apply nematodes for slugs. I don't have the money to apply every 6 weeks. I did apply one lot in the spring and it did keep the little blighters away until the end of may. I think i applyed it at the end of april. However last week in digging up my maris piper potatoes i found some slugs be them small ones inside my potatoes. I can maybe afford nematodes once in a season at a push twice. Did i apply them at the right time?

Thanx ever so much i will have to go and get a soil thermometer now! So if twice a year is sufficent when would be the best time to reapply the nematodes? This is my first year of growing fruit and veg so i'm a begginner! thanx again

I would think that spring would be a good time, or when you plant the first potatoes, anyway! - but I'm no expert, I'm afraid.

Thanx it's all by trial and error we learn from our mistakes! mine was to not put butterfly netting up!

Oh dear. Well - at least there are more butterflies around! Not good for your cabbages, though. :-(

The Nematodes work when the soil reaches a temperature of 5°C/41°F and it's damp. They do only last for six to eight weeks, so you do need another application, as twice a year seems be sufficient for most gardens.
