Rocket, also called arugula, is an edible and quite piquant green plant that is usually used in salads, sandwiches, etc. Rocket is one of the easiest vegetables to grow in containers and the following are tips on how to grow them. If you live in a small apartment and have no space to grow large plants or just love getting fresh vegetables and lettuces at your and you fingertips, then you are in the right place.
Why Grow Rocket in Containers?
Convenience and Accessibility
Having rocket in containers means fresh greens are just a step away. You can quickly snip what you need for a meal, making your dishes fresher and more flavourful.
Space-Saving Solution
Containers are perfect for small spaces. Whether you have a patio, balcony, or windowsill, you can still grow rocket. This method lets anyone enjoy home-grown greens.
Control Over Growing Conditions
Containers give you control over soil, water, and sunlight. This can lead to healthier plants and better harvests.
Choosing the Right Container
Size and Depth
Rocket has shallow roots, so you don’t need a deep container. A pot that is at least 6 inches deep is enough. Ensure the container is wide enough for the plants to spread out.
Drainage
Good drainage is key. Choose containers with holes at the bottom to prevent water from sitting in the soil and causing root rot.
Material
Containers can be plastic, clay, or fabric:
- Plastic Pots: Light and easy to move but can retain too much water.
- Clay Pots: Look nice and keep roots cool but can break.
- Fabric Pots: Great for root health but dry out quickly.
Preparing the Soil
The Perfect Mix
Rocket grows best in well-drained, fertile soil. Use high-quality potting mix and add compost for nutrients. Avoid heavy clay soils, which can hinder growth.
Fertilizing
Before planting, mix in some slow-release fertilizer or compost. Rocket grows quickly and needs nutrients to thrive.
Planting Your Rocket
Choosing Seeds
Pick rocket seeds from a reliable source. Varieties like ‘Astro’ or ‘Wild Rocket’ are great and provide a steady harvest.
Sowing Seeds
- Fill the Container: Fill with soil mix, leaving an inch at the top.
- Plant the Seeds: Scatter seeds evenly over the soil surface. Cover lightly with soil, about a quarter inch deep.
- Water Gently: Water gently to keep seeds in place. Keep the soil moist until seeds sprout.
Thinning Seedlings
Once seedlings are a few inches tall, thin them out to about 4–6 inches apart. This gives each plant room to grow.
Caring for Your Rocket Plants
Watering
Rocket needs consistent moisture. Water regularly to keep soil moist but not soggy. Mulching helps retain moisture.
Feeding
If you used slow-release fertilizer or compost, you may not need to feed again. If growth slows or leaves pale, use a balanced liquid fertilizer every few weeks.
Light and Temperature
Rocket likes cool weather and can handle some shade. Place your container where it gets 4–6 hours of sunlight daily. In hot climates, afternoon shade prevents bolting.
Winter Hardy Information
Growing Rocket in Winter
Rocket tolerates cool temperatures, making it perfect for fall and early spring. In mild climates, it can grow through winter.
Protecting Your Plants
In harsh winters, protect container-grown rocket by moving pots to a sheltered spot like a greenhouse or garage. Or cover plants with a cloche or frost cloth.
Harvesting in Cold Weather
Rocket tastes sweeter and less bitter in cool weather. Harvest leaves throughout winter, as long as they’re protected from severe frost.
Harvesting Your Rocket
When to Harvest
Harvest rocket when leaves are large enough to eat, usually 4–6 weeks after planting. Pick outer leaves first for a continuous harvest.
How to Harvest
Use scissors or fingers to snip leaves. Regular harvesting encourages new growth. If plants start to flower, leaves may become bitter, so harvest often.
Enjoying Your Harvest
Rocket is versatile. Use it in salads, sandwiches, and as a garnish for soups and pizzas. Its peppery flavour adds a kick to many dishes.
Growing Rocket in Containers: Final Tips
Common Problems and Solutions
- Bolting: Provide shade and water regularly to prevent rocket from bolting in hot weather.
- Pests: Watch for aphids and flea beetles. Use natural deterrents or organic sprays.
- Poor Growth: Ensure your plants get enough sunlight and nutrients. Regular feeding and proper spacing help.
Companion Planting
Rocket grows well with lettuce, spinach, and radishes. Companion planting helps deter pests and maximizes space.
Conclusion
Growing rocket in containers is a fun and rewarding way to enjoy fresh, home-grown greens. With the right container, soil, and care, you can harvest delicious rocket even if you have limited space. Follow this guide, and soon you’ll be enjoying the peppery taste of rocket from your own container garden.
