Love rhubarb but short on space?
No problem!
You can grow it in a container.
Here are 9 easy tactics to help you succeed.
Ready to harvest your own rhubarb? Let’s get started!
Choose the Right Container
First things first, you need to pick the right container. Rhubarb plants have deep roots, so you’ll need something pretty big.
Aim for a pot that’s at least 20 inches deep and wide. Make sure it has drainage holes at the bottom to avoid waterlogging.
You don’t want your rhubarb to drown!
Use Rich, Well-Draining Soil
Rhubarb loves nutrient-rich soil, so use a high-quality potting mix. Mix in some compost or well-rotted manure to give it an extra boost.
The soil should be well-draining to keep the roots healthy. If you notice water pooling at the top, you might need to add some sand or perlite to improve drainage.
Plant at the Right Time
Timing matters when planting rhubarb. The best time to plant is in early spring when temperatures are cooler.
You can also plant in early autumn if you live in a milder climate. Rhubarb loves cool weather to get started, so take advantage of those chilly days.
Water Regularly but Don’t Overdo It
Rhubarb needs consistent moisture to thrive, but too much water can be just as bad as too little. Keep the soil moist, not soggy.
Water deeply and make sure excess water drains out of the pot. During hot weather, you might need to water more often, but always check the soil before adding more water.
Give It Some Sun
Rhubarb needs plenty of sunlight to grow big and strong. Place your container in a spot that gets at least six hours of sunlight each day.
If you live in a very hot climate, a bit of afternoon shade can help prevent the leaves from getting scorched.
Feed Your Rhubarb
Rhubarb plants are heavy feeders, so give them some food! Use a balanced, all-purpose fertilizer every 4-6 weeks during the growing season.
You can also topdress with compost to keep the soil nutrient-rich. Feeding your rhubarb will help it produce those juicy stalks you love.
Watch for Pests and Diseases
Rhubarb is pretty hardy, but it’s still good to keep an eye out for pests like aphids and slugs. If you see any, treat your plant with a natural insecticide or remove pests by hand.
Also, look out for signs of disease like crown rot and take action quickly if you spot any issues.
Harvesting Your Rhubarb
Patience is key when it comes to harvesting rhubarb. Wait until the second growing season to start picking stalks.
When you do start harvesting, choose stalks that are at least 12 inches long. Gently pull them from the base and twist to remove.
Remember, don’t eat the leaves—they’re toxic!
Prepare for Winter
If you live in a colder climate, you’ll need to prepare your rhubarb for winter. Move the container to a sheltered spot and mulch the top of the soil to protect the roots.
In very cold areas, you can even bring the container indoors or into a garage to keep it safe from freezing temperatures.
