Planting Rhubarb in the Wrong Location
Rhubarb needs:
- Full sun (at least 6 hours daily)
- Well-draining soil
Planting in too much shade or soggy soil can lead to weak growth or root rot.
Choose a sunny spot with good drainage for best results.
Overwatering Rhubarb
One of the biggest mistakes is giving rhubarb too much water.
While it likes moisture, it does not like sitting in wet soil.
Water deeply, but let the soil dry slightly between waterings.
Harvesting Too Soon
It’s tempting to harvest right away—but this can weaken your plant.
- Avoid harvesting in the first year
- In the second year, harvest lightly
- By year three, you can harvest normally
Patience leads to stronger, more productive plants.

Not Dividing Mature Plants
Over time, rhubarb plants can become crowded and less productive.
Divide plants every 3–5 years to keep them healthy and growing strong.
If your plants are getting crowded, here’s how to divide rhubarb step-by-step and transplant rhubarb properly to keep them healthy and productive.
Letting Flower Stalks Grow
Rhubarb will sometimes produce flower stalks, especially in warmer weather.
These take energy away from the plant.
Remove flower stalks as soon as you see them.
Using Poor Soil
Rhubarb is a heavy feeder and needs nutrient-rich soil.
Add compost or organic matter to improve soil quality and support growth.
Forgetting Seasonal Care
Rhubarb needs a natural cycle:
- Dormancy in winter
- Strong regrowth in spring
Don’t panic if it dies back—it will return in the next growing season.
You can also preserve your harvest by freezing rhubarb or using it in simple homemade recipes.
Rhubarb is one of the easiest perennial plants to grow once you understand the basics. Avoiding these common mistakes will help you grow healthier plants and enjoy a better harvest year after year.
