Planting & Care

Site Selection

  • Choose a site with good sun exposure for best growth and fruit size.
  • Full sun is ideal, but at least 1/2 day of sun is sufficient.
  • Good airflow supports healthy vines and consistent fruiting.
  • Install permanent support structures before vines reach full size.

Soil Preparation

  • Kiwi berries grow best in well-drained soil.
  • Avoid areas with standing water or compacted ground.
  • Light compost amendment can improve poor soils.

Planting Instructions

  • Dig a hole twice as wide as the root system.
  • Plant at the same depth as the container-grown vine.
  • Backfill with native soil and water thoroughly.
  • Mulch 2–3 inches deep to stabilize moisture (keep mulch off the stem).

Watering & Fertilizing

  • Water consistently during the first 1–2 years.
  • Deep watering encourages strong root development.
  • Once established, allow soil to partially dry between waterings.
  • Apply compost or a balanced fertilizer in early spring if growth is weak.

Support & Training

  • Install trellising, an arbor, or pergola at planting time.
  • Train a single strong leader upward during the first year.
  • Establish one or two permanent horizontal cordons along the support.

Pruning & Training (Think Grapes)

  • Hardy kiwis are pruned using a grape-style system.
  • Fruit is produced on new shoots growing from last year’s wood.
  • In winter, cut back fruiting growth to short spurs with 2–4 buds.
  • Summer pruning helps control vigor and improve light exposure.

Pollination

  • Michigan State is a female kiwi berry and is not self-fertile.
  • Plant a compatible male hardy kiwi within 20–30 feet.
  • One healthy male can pollinate multiple female vines.

Harvest & Use

  • Harvest when fruit reaches full size and begins to soften slightly.
  • Fruit may ripen unevenly and is often picked in stages.
  • Allow fruit to finish ripening off the vine if needed.
  • Enjoy fresh for best flavor and texture.

General Tips

  • Focus on structure and training in the first year.
  • Consistent pruning keeps vines productive and manageable.
  • Strong support is essential for long-term success.

Description

Michigan State is a hardy kiwi berry selected through university evaluation for dependable growth, large fruit, and consistent eating quality. The smooth-skinned, green berries ripen to a generous, grape-sized size with clean, sweet kiwi flavor, making it a reliable performer rather than a novelty variety.

This selection is often appreciated for how well it balances fruit size, productivity, and vine vigor. The berries size up well without sacrificing consistency, and the vine itself grows strongly once established, responding well to training and annual pruning.

Kiwi berries—also known as hardy kiwi—are smooth-skinned, bite-size kiwis that you eat whole, skin and all. Unlike fuzzy kiwis from the grocery store, these grape-sized fruits require no peeling and soften slightly as they ripen, developing a sweet, tropical kiwi flavor that’s easy to enjoy fresh. Michigan State fits well on trellises, arbors, and pergolas where long-term productivity and reliability matter.
