Rhubarb: How to Grow, Use and Stay Safe

Rhubarb is tart, bright, and often treated like a fruit in the kitchen — but it's a vegetable. Want to bake a pie, make a quick compote, or plant a patch in your yard? This page gives clear, practical tips so you can use rhubarb without guessing.

First things first: only the stalks are edible. Rhubarb leaves contain oxalic acid and can make you very sick if eaten in quantity. Cut leaves off and compost them away from children and pets. Always wash stalks before cooking.

What rhubarb gives you: nutrition and uses

Rhubarb is low in calories, has fiber, vitamin K, and some calcium. It’s not a vitamin powerhouse, but it adds bright flavor and texture. Use it in pies, tarts, jams, sauces, or mixed with sweeter fruits like strawberries to balance the tartness. You can also stew rhubarb into compote for yogurt, toast, or ice cream.

Want a savory spin? Try rhubarb in chutneys or paired with pork for a tangy kick. If you like cocktails, muddled rhubarb or a rhubarb syrup makes a lively mixer.

Growing & Storing Rhubarb

Rhubarb plants are hardy and low-maintenance. Plant crowns in early spring in well-drained soil with full sun to partial shade. Space plants about 3 feet apart. Water during dry spells and mulch to keep roots cool. Don’t harvest heavily in the first two years — let the plant establish itself.

When to harvest? Pick thick, firm stalks by twisting and pulling gently at the base. Avoid cutting too close to the crown. In general, harvest from the third year onward for larger yields. If leaves are pale or small, feed with compost in spring.

Store fresh stalks unwashed in the fridge, wrapped in a damp cloth or plastic, for up to two weeks. For longer storage, chop and freeze stalks raw or cook into compote and freeze in portions.

Cooking tip: rhubarb softens quickly. Add sugar gradually — you can always add more, but you can’t remove it. For less sugar, pair rhubarb with ripe bananas, apples, or a splash of orange juice to round the tartness.

Quick compote method: chop 500g rhubarb, add 50–80g sugar (adjust to taste), a splash of water, and simmer 8–10 minutes until soft. Stir in a teaspoon of vanilla or a pinch of cinnamon. Cool and use on yogurt, pancakes, or as a cake filling.

Final safety note: never eat rhubarb leaves. If you have kidney disease or take blood thinners, check with your doctor before adding large amounts of rhubarb to your diet because of vitamin K and oxalates. Otherwise, enjoy its bright flavor and simple recipes all year long.
