How can I keep potato tu­ber moths off our spuds?

Hastings Leader - - Gardening -

With dif­fi­culty. The potato tu­ber moth is a world­wide pest found through­out NZ. And sprays aren’t much use, with up to six gen­er­a­tions per year to con­tend with. Po­ta­toes planted too shal­low or ex­posed through cracked soils are more likely to be at­tacked, so plant them in a trench around 20cm deep be­fore cov­er­ing with 10cm of soil. Then keep earth­ing them up, which pre­vents frost dam­age as well as foil­ing the moth in the mean­time. Fre­quent wa­ter­ing also helps. If you have a gar­den ques­tion email Glenys at
