About Hardy Kiwi

Actinidia arguta · also called hardy kiwi, baby kiwi · edible

Actinidia arguta is a vigorous deciduous climbing vine bearing small, smooth-skinned, grape-sized kiwi berries eaten whole. Far hardier than fuzzy kiwi, it withstands hard frost once established. Most plants are dioecious, so a male is needed to pollinate females. Given a strong support and a long season, it crops heavily in autumn.

Mature size: Up to 6-9 m of vine (20-30 ft) on support

Watch for — Frost damage to spring growth: Soft new shoots and flowers are killed by late frosts, wiping out a crop. Plant in a sheltered, sunny spot away from frost pockets and protect early growth if frost threatens.

How to tell hardy kiwi needs repotting

Repotting on a calendar is less reliable than reading the plant. For hardy kiwi, watch for these signs:

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot hardy kiwi

Pot on seedlings as they grow; not a perennial repot. Hardy Kiwiis grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Extremely vigorous, twining deciduous vine that can extend many metres a year; needs robust permanent support. Fruits on current-season shoots arising from one-year-old wood, so regular pruning is essential..

What size pot to step hardy kiwi up to

Pot hardy kiwi on gradually — a seedling jumped straight into a huge pot sits in cold, wet, airless soil and stalls. Step up one or two sizes at a time as the roots fill each container, finishing in a large final pot or the ground. The aim is roots that never circle and never check.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot hardy kiwi

Pot hardy kiwi on through the active growing season, whenever roots fill the current container — there is no single date, just "before it becomes root-bound". Avoid potting on during a cold snap.

Step-by-step: repotting hardy kiwi

  1. Pot on before it is root-bound. Check hardy kiwi regularly; move it up as soon as roots reach the edge of the cell or pot, not after they have circled.
  2. Step up one or two sizes. Choose the next container up — not a giant one. Cold, wet, unused soil around a small root system stalls seedlings.
  3. Knock it out gently. Support the stem, tip the pot, and ease the rootball out without breaking it. A little teasing of circled roots at the base is fine.
  4. Pot into rich mix. Set it into fresh deep, fertile, free-draining loam at the same depth (tomatoes are the exception — they can go deeper to root along the stem).
  5. Water in and grow on. Water well, keep it in good light, and resume feeding once it is established and growing again.

Aftercare

Water hardy kiwi in well and keep it in bright light; a freshly potted-on seedling can wilt for a day while roots settle, so do not overcompensate by drowning it. Do not fertilise for about 1 week — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for hardy kiwi

Hardy Kiwi wants deep, fertile, free-draining loam. Prefers a slightly acidic pH of about 5.5-6.5 and resents lime. Dig in generous organic matter. Drainage is critical, as the fleshy roots rot in heavy, wet ground; improve clay before planting. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting hardy kiwi — frequently asked questions

How often should you repot hardy kiwi?

Pot on seedlings as they grow; not a perennial repot for hardy kiwi. Hardy Kiwi is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into deep, fertile, free-draining loam so the roots never circle the cell, ending in a large final container. A root-bound transplant stalls and never fully recovers.

What size pot does hardy kiwi need?

Pot hardy kiwi on gradually — a seedling jumped straight into a huge pot sits in cold, wet, airless soil and stalls. Step up one or two sizes at a time as the roots fill each container, finishing in a large final pot or the ground. The aim is roots that never circle and never check. Use our pot size calculator to size it from the plant's current pot and root spread.

When is the best time of year to repot hardy kiwi?

Pot hardy kiwi on through the active growing season, whenever roots fill the current container — there is no single date, just "before it becomes root-bound". Avoid potting on during a cold snap.

Can you put hardy kiwi straight into a much bigger pot?

No. Even a fast-growing hardy kiwi should only go up one pot size at a time. A vastly oversized pot holds a reservoir of wet soil the roots cannot reach, which stays cold and soggy and rots the roots — the opposite of what you wanted.

Should you fertilise hardy kiwi after repotting?

Not immediately. Wait about 1 week after repotting hardy kiwi. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
