About Goji Berry

Lycium barbarum · also called goji berry, wolfberry · edible

The goji or wolfberry is a hardy, sprawling Solanaceae shrub from Asia, grown for its small bright-orange-red berries rich in antioxidants. Tough and drought-tolerant once established, it tolerates poor soil, salt and wind, fruiting on new wood from summer into autumn. Vigorous and arching, it benefits from support or a trellis to keep fruit accessible.

Mature size: 1.5-2.5 m tall with arching canes spreading 2-4 m unless trained or pruned; suckers can extend the patch.

How to tell goji berry needs repotting

Repotting on a calendar is less reliable than reading the plant. For goji berry, 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 goji berry

Pot on seedlings as they grow; not a perennial repot. Goji Berryis grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Deciduous, arching to scrambling shrub with long whippy thorny canes that root where they touch ground; fruits on the current season's growth and can sucker into a thicket if unchecked..

What size pot to step goji berry up to

Pot goji berry 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 goji berry

Pot goji berry 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 goji berry

  1. Pot on before it is root-bound. Check goji berry 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 free-draining, neutral to alkaline soil 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 goji berry 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 goji berry

Goji Berry wants free-draining, neutral to alkaline soil. Thrives on pH 6.5-8.0 and tolerates poor, sandy, stony and saline ground that defeats fussier fruit. Good drainage matters more than fertility; heavy, wet clay encourages root rot and should be lightened or raised. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting goji berry — frequently asked questions

How often should you repot goji berry?

Pot on seedlings as they grow; not a perennial repot for goji berry. Goji Berry is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into free-draining, neutral to alkaline soil 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 goji berry need?

Pot goji berry 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 goji berry?

Pot goji berry 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 goji berry straight into a much bigger pot?

No. Even a fast-growing goji berry 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 goji berry after repotting?

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