About Potato
Potatoes are blight-susceptible nightshades — rotate away from tomatoes and eggplant, and pair with beans for nitrogen and marigolds for nematode suppression.
Plant seed potatoes after frost risk — stagger plantings for extended harvest.

Avoid planting together

Growing tips
- Hill soil as stems grow; never plant where tomatoes grew last season.
- Early and maincrop varieties spread harvest across seasons.
- Psyllid monitoring matters in North Island commercial and home beds.
