About Marketmore Cucumber

Cucumis sativus 'Marketmore' · also called Marketmore cucumber, slicing cucumber · edible

'Marketmore' (notably 'Marketmore 76') is a reliable open-pollinated outdoor slicing cucumber producing straight, dark-green fruit 18-20 cm long. Bred for disease resistance — including scab and cucumber mosaic virus — it is a hardy, heavy-cropping ridge type that performs well in cool-temperate gardens without a greenhouse.

Mature size: 1.5-2 m trailing or climbing; fruit 18-20 cm long

Watch for — Cucumber beetles: In the US, striped/spotted beetles chew foliage and spread bacterial wilt. Use floating row cover until flowering, then remove for pollination, and monitor closely.

How to tell marketmore cucumber needs repotting

Repotting on a calendar is less reliable than reading the plant. For marketmore cucumber, 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 marketmore cucumber 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 marketmore cucumber

Pot on seedlings as they grow; not a perennial repot. Marketmore Cucumberis grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Vigorous monoecious (male and female flowers) ridge-type vine that trails or climbs by tendrils. Can sprawl on the ground or be trained up netting; productive and resilient, with a long harvest window if picked often..

What size pot to step marketmore cucumber up to

Pot marketmore cucumber 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 marketmore cucumber

Pot marketmore cucumber 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 marketmore cucumber

Pot on before it is root-bound. Check marketmore cucumber 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, free-draining loam high in organic matter, ph 6.0-6.8 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 marketmore cucumber 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 marketmore cucumber

Marketmore Cucumber wants fertile, free-draining loam high in organic matter, ph 6.0-6.8. Wants rich, well-drained soil improved with compost or rotted manure. Forgiving and robust outdoors, but avoid cold, waterlogged clay, which stunts growth and rots seedlings. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting marketmore cucumber — frequently asked questions

How often should you repot marketmore cucumber?

Pot on seedlings as they grow; not a perennial repot for marketmore cucumber. Marketmore Cucumber is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into fertile, free-draining loam high in organic matter, ph 6.0-6.8 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 marketmore cucumber need?

When is the best time of year to repot marketmore cucumber?

Can you put marketmore cucumber straight into a much bigger pot?

No. Even a fast-growing marketmore cucumber 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 marketmore cucumber after repotting?

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