🥬 Rhubarb
Rheum rhabarbarum
The vegetable crashing the fruit party — and the leaves are NOT invited to dinner.
Sun
Full sun
Days to harvest
2–3 years before harvesting; don't touch it the first year
Spacing
3–4 ft apart
Soil pH
6.0–7.0
How to grow
Plant crowns in early spring with buds just at the soil surface, then leave it alone to establish — harvesting year one weakens the crown permanently. Rhubarb needs winter chill and rots in Florida heat, so Southern gardeners should treat it as a fun experiment, not a plan.
Water & feeding
Steady moisture; mulch to keep roots cool.
Common problems
- Needs real winter chill — no chill, no vigor
- Crown rot in hot, wet soil
- Rhubarb curculio beetles bore into stalks
Harvest
Twist and pull stalks (don't cut) once they're a foot or more long. NEVER eat the leaves — they're loaded with oxalic acid. Stalks only, always.
Nerdy fact: Botanically a vegetable, but a US court ruled rhubarb a fruit in 1947 — for tariff purposes, because it was being used like one. It's the only produce with a legal identity crisis.
