About Cylindra Beetroot

Beta vulgaris 'Cylindra' · also called Cylindra beet, cylinder beet · edible

'Cylindra' is a heritage beetroot with long, cylindrical dark-red roots instead of globes, giving many uniform slices per root and high yield per row. Sweet, tender and good for storage, it grows like round beet but its roots push partly out of the ground as they lengthen. Sow successionally and harvest before roots grow over-large and coarse.

Mature size: Roots 15-20 cm long and about 5 cm across; foliage rosette 25-30 cm tall and wide.

Watch for — Green, exposed shoulders: The long roots heave out of the soil and the exposed tops toughen. Earth up or mulch over the shoulders to keep them tender.

How to tell cylindra beetroot needs repotting

Repotting on a calendar is less reliable than reading the plant. For cylindra beetroot, 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 cylindra beetroot 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 cylindra beetroot

Pot on seedlings as they grow; not a perennial repot. Cylindra Beetrootis grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Low leaf rosette above a long, tapering cylindrical taproot that emerges noticeably above the soil line as it matures..

What size pot to step cylindra beetroot up to

Pot cylindra beetroot 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 cylindra beetroot

Pot cylindra beetroot 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 cylindra beetroot

Pot on before it is root-bound. Check cylindra beetroot 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 deep, light, free-draining loam 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 cylindra beetroot 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 cylindra beetroot

Cylindra Beetroot wants deep, light, free-draining loam. Stone-free, well-worked soil, pH 6.5-7.5; the long roots need depth and a fine tilth to elongate cleanly. Avoid fresh manure, which forks the roots. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting cylindra beetroot — frequently asked questions

How often should you repot cylindra beetroot?

Pot on seedlings as they grow; not a perennial repot for cylindra beetroot. Cylindra Beetroot is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into deep, light, 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 cylindra beetroot need?

When is the best time of year to repot cylindra beetroot?

Can you put cylindra beetroot straight into a much bigger pot?

No. Even a fast-growing cylindra beetroot 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 cylindra beetroot after repotting?

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