Choose a sunny open site in which to plant your rhubarb crown as rhubarb does not grow well in shade. Spring is the perfect time to plant a rhubarb crown. Make sure the site is weed-free and dig lots of organic matter in to the soil. Most soils are suitable for growing rhubarb apart from soils that are frequently waterlogged, as they can cause the crown to rot.
Dig a hole and plant the crown with the growing point level with or just below the soil surface and firm in. If you are planting more than one rhubarb crown, space the plants 1m (3 1/4ft) apart, with 90cm – 2m (3 – 7ft) between rows.
