About Cambridge Favourite Strawberry

Fragaria × ananassa 'Cambridge Favourite' · also called Cambridge Favourite strawberry · edible

'Cambridge Favourite' is a long-trusted British summer-fruiting strawberry, reliable and disease-resistant, producing medium-sized, sweet-but-mild orange-red berries in midsummer. Bred in the 1950s, it crops heavily, tolerates a range of conditions and is forgiving for beginners. As a June-bearer it fruits once a season and propagates freely from runners.

Mature size: Plants reach 20-30 cm tall and 30-40 cm wide, spreading further as runners root; replace plants every three to four years as vigour declines.

Watch for — Vine weevil (in containers): C-shaped larvae eat roots, causing sudden collapse of potted plants. Use biological nematode controls in late summer and check roots when repotting.

How to tell cambridge favourite strawberry needs repotting

Repotting on a calendar is less reliable than reading the plant. For cambridge favourite strawberry, watch for these signs:

Roots circling the bottom of the module or pot, or poking out of the drainage holes.
The seedling dries out within a day and growth has visibly stalled.
Roots are white and matted in a tight spiral when you tip the plant out.
It has outgrown its current container for the stage of the season — pot cambridge favourite strawberry on before it becomes hard root-bound.

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 cambridge favourite strawberry

Pot on seedlings as they grow; not a perennial repot. Cambridge Favourite Strawberryis grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Low, clump-forming herbaceous perennial spreading by runners (stolons) that root to form new plants; June-bearing, fruiting in a single summer flush..

What size pot to step cambridge favourite strawberry up to

Pot cambridge favourite strawberry 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 cambridge favourite strawberry

Pot cambridge favourite strawberry 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 cambridge favourite strawberry

Pot on before it is root-bound. Check cambridge favourite strawberry regularly; move it up as soon as roots reach the edge of the cell or pot, not after they have circled.
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.
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.
Pot into rich mix. Set it into fresh fertile, well-drained loam high in organic matter at the same depth (tomatoes are the exception — they can go deeper to root along the stem).
Water in and grow on. Water well, keep it in good light, and resume feeding once it is established and growing again.

Aftercare

Water cambridge favourite strawberry 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 cambridge favourite strawberry

Cambridge Favourite Strawberry wants fertile, well-drained loam high in organic matter. Prefers slightly acidic soil at pH 5.5-6.8. Dislikes heavy, waterlogged ground, which causes crown rot. Improve beds with compost; in pots use a loam-based mix with added grit. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting cambridge favourite strawberry — frequently asked questions

How often should you repot cambridge favourite strawberry?

Pot on seedlings as they grow; not a perennial repot for cambridge favourite strawberry. Cambridge Favourite Strawberry is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into fertile, well-drained loam high in organic matter 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 cambridge favourite strawberry need?

When is the best time of year to repot cambridge favourite strawberry?

Can you put cambridge favourite strawberry straight into a much bigger pot?

No. Even a fast-growing cambridge favourite strawberry 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 cambridge favourite strawberry after repotting?

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