About Burpless Cucumber

Cucumis sativus 'Burpless Tasty Green' · also called Burpless cucumber, burpless tasty green · edible

'Burpless Tasty Green' is a low-cucurbitacin, thin-skinned slicing cucumber bred to be mild, sweet and easy to digest — the 'burpless' trait. Its slender, ridged fruit reach 20-25 cm. Vigorous and versatile, it crops well both outdoors and under cover, and is best eaten unpeeled while young and tender.

Mature size: 1.8-2.2 m trained vertically; fruit 20-25 cm long

Watch for — Powdery mildew: White leaf film in stuffy or dry-rooted conditions. Ventilate under cover, keep roots moist, water the soil not the leaves, and strip affected foliage.

How to tell burpless cucumber needs repotting

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

Pot on seedlings as they grow; not a perennial repot. Burpless Cucumberis grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Vigorous trailing/climbing vine that crops over a long season. Train up netting, canes or string and pinch side-shoots to manage it; produces a steady flush of long, slim fruit if picked regularly..

What size pot to step burpless cucumber up to

Pot burpless 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 burpless cucumber

Pot burpless 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 burpless cucumber

Pot on before it is root-bound. Check burpless 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 rich, free-draining, organic-matter-rich loam or quality potting mix, 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 burpless 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 burpless cucumber

Burpless Cucumber wants rich, free-draining, organic-matter-rich loam or quality potting mix, ph 6.0-6.8. Likes fertile, moisture-retentive but well-drained soil. Works well in grow bags and large containers with peat-free mix; plant slightly proud at the collar to avoid stem rot. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting burpless cucumber — frequently asked questions

How often should you repot burpless cucumber?

Pot on seedlings as they grow; not a perennial repot for burpless cucumber. Burpless Cucumber is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into rich, free-draining, organic-matter-rich loam or quality potting mix, 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 burpless cucumber need?

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

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

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

Not immediately. Wait about 1 week after repotting burpless 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.
