Rhubarb Crown Calculator — Spacing & Yields
Work out spacing and yields for rhubarb crown planting.
How We Calculate This
Crowns = plants that fit along length x plants that fit along width, based on the recommended spacing for the variety.
Standard varieties: 90cm apart. Compact: 75cm. Large: 120cm. Rhubarb needs plenty of space to develop strong crowns.
Yield estimates are for established plants (year 3+) over a typical April-June harvest season.
