Growing Rhubarb In Pots: A Guide to Delicious Homemade Pies
If you're a fan of rhubarb pies or crumbles, why not try growing your own rhubarb in pots? Not only is it a fun and rewarding hobby, but it also ensures that you have a steady supply of fresh, organic rhubarb at your fingertips. In this guide, we'll walk you through the steps of growing rhubarb in pots, from choosing the right container to harvesting your crop.
Choosing the Right Container
The first step to growing rhubarb in pots is to choose the right container. Rhubarb has deep roots, so you'll need a container that's at least 12 inches deep and 18 inches wide. Terra cotta, plastic or wooden containers work well, but make sure there are drainage holes at the bottom.
It's also important to consider the location of your pot. Rhubarb needs plenty of sunlight to grow, so place your pot in a sunny spot, like a south-facing window or a balcony that gets at least six hours of direct sunlight per day.
Preparing the Soil
Rhubarb prefers slightly acidic soil with a pH between 6.0 and 6.8. You can buy a soil testing kit at your local garden center to check the pH of your soil. If the pH is too high, add sulfur or peat moss to lower it.
Fill your container with a good quality compost or potting mix, leaving about two inches of space at the top. Mix in some well-rotted manure or compost to improve the soil's fertility. Rhubarb also prefers soil that's rich in organic matter, so adding some leaf mold, grass clippings or shredded bark will help keep the soil moist and fertile.
Planting Rhubarb in Pots
Rhubarb is usually grown from crowns, which are available at most garden centers in early spring. Plant them in late winter or early spring, when the soil is still cold, to encourage strong root growth.
Place the crown in the center of the pot, with the buds facing up and the roots pointing downwards. Cover the crown with two inches of soil, water thoroughly and place the pot in a sunny spot. As the plant grows, continue to add soil to the pot until the soil level reaches the rim of the container.
Caring for Your Rhubarb Plant
Rhubarb requires regular watering to keep the soil moist, especially during hot, dry weather. Water your plant deeply once a week, making sure to soak the soil all the way down to the roots.
Fertilize your plant every spring with a slow-release fertilizer that's rich in nitrogen, phosphorus and potassium. This will help promote strong stem growth and large, juicy rhubarb stalks.
Keep an eye out for pests and diseases, like slugs, aphids or powdery mildew, which can damage your plant. If you notice any signs of insect damage or fungal growth, remove the affected leaves or stems and treat the plant with an organic pesticide or fungicide.
Harvesting Your Rhubarb Crop
Rhubarb usually takes two to three years to reach maturity, but once it's established, it can produce a crop for up to 20 years. Harvest your rhubarb in late spring or early summer, when the stalks are firm and crisp.
To harvest the rhubarb, grasp the stalk near the base and pull gently. Twist the stalk slightly to detach it from the crown. Cut off the leaves, which are toxic to humans, and discard them in your compost bin.
Enjoy your freshly harvested rhubarb in pies, crumbles, jams or sauces!
