Rhubarb

Rheum × hybridum

Large, crinkled leaves rise on thick red and pink stalks from a lasting crown.

Make it part of your growing collection.

A LITTLE EVERYDAY CARE

Help it thrive.

A few things worth knowing.
01

Let new plants establish

Do not harvest in the first year; take only a few stalks in the second.

02

Mulch around the crown

Apply mature compost around the plant while keeping its crown exposed.

03

Avoid waterlogging

Keep young and container plants watered during dry growth periods, with good drainage.
