How to Grow Rhubarb: 15 Steps
Rhubarb is a versatile and hardy perennial vegetable that can be used in various culinary dishes such as pies, jams, and sauces. It has a unique, tangy flavor and is relatively easy to grow. Here are the 15 steps to successfully grow rhubarb in your garden.
1. Choose the right location: Rhubarb thrives in well-drained, fertile soil with a pH level between 6.0 and 6.8. Pick a spot that receives full sun or partial shade.
2. Prepare the soil: Loosen the soil using a fork or tiller and mix in organic matter such as compost or well-rotted manure to improve fertility.
3. Obtain rhubarb crowns: Purchase disease-free, one-year-old crowns from a reputable nursery or garden center.
4. Plant in early spring: The best time to plant rhubarb is in early spring when the soil is workable.
5. Dig holes for the crowns: Space the holes about 36 inches apart and make them deep enough so that the top of the crown is just below the soil surface.
6. Set the crowns into the holes: Position them so that the buds are facing upwards.
7. Cover with soil: Fill in the hole with soil, ensuring that it’s well-packed around the crown to eliminate air pockets.
8. Water thoroughly after planting: Keep the soil consistently moist but not waterlogged throughout the growing season.
9. Apply mulch: Use organic mulches like straw or shredded leaves to conserve moisture and reduce weed growth around your rhubarb plants.
10. Monitor for pests & diseases: Check regularly for signs of insects like slugs, snails, and root maggots which can damage your rhubarb plants.
11. Fertilize annually: Apply a balanced fertilizer before new growth emerges in the spring.
12. Harvest responsibly: Do not harvest any stalks during the first year of growth, as this allows your rhubarb to establish a strong root system. In the second year, harvest about half of the stalks and then increase harvests gradually from the third year onwards.
13. Remove seed stalks: Cut back any seed stalks that appear, as allowing them to develop can reduce the vigor and productivity of your rhubarb plants.
14. Divide crowded plants: When rhubarb plants become overcrowded (after about four years), divide them by digging up the entire plant, cutting it into pieces with a sharp spade, and replanting the healthiest sections.
15. Prepare for winter: Trim back the leaves once they start to die off in fall and add a layer of mulch over the crowns for protection during winter months.
By following these 15 steps, you’ll be well on your way to enjoying a bountiful harvest of delicious rhubarb from your garden.
