Low growing bush type. Plants produce tubers in one layer just below the soil surface and so do not require mounding of the soil around them. They usually have a lower yield than indeterminate (tall bush) types but do produce tubers earlier, in about 70 to 90 days. If you live in a very cold climate with a short growing season, these are the best choice.
When planting determinate varieties, dig the soil, adding compost and planting the tubers 10cm deep, about 35 to 40cm apart. The 'no-dig' method works particularly well with determinate types which involves placing the tubers on the surface of the soil and mulching heavily with straw and composted manure. The potatoes will form tubers on top of the ground rather than up through the mulch where they risk being exposed to light. The mulch needs to be kept thick to avoid damage by sunlight.
