This guide will equip you with the knowledge you need to master the art of how to grow leeks rhs, from seed sowing to harvesting.
Understanding the RHS’s Expertise
The Royal Horticultural Society (RHS) is a renowned authority on all things gardening, offering invaluable advice and resources for home gardeners. Their expertise is particularly valuable when it comes to growing leeks, a vegetable that can sometimes be tricky to master. This blog post will draw upon their recommendations, ensuring you have the best possible chance of success.
Choosing the Right Variety
The first step to successful leek cultivation is choosing the right variety. The RHS recommends several varieties that are well-suited to the UK climate:
- ‘Musselburgh’: This classic variety is known for its large, tender, and flavorful leeks.
- ‘King Richard’: This variety produces sturdy, thick leeks that are perfect for winter storage.
- ‘Winter Giant’: As its name suggests, this variety is ideal for growing over the winter months.
Sowing Leek Seeds: Timing is Key
The RHS recommends sowing leek seeds indoors, ideally between February and April. This allows the seedlings to establish strong roots before being transplanted outdoors.
- Direct Sowing: If you prefer, you can also sow seeds directly outdoors in April or May.
- Seed Trays: Fill seed trays with a good quality seed compost and sow the seeds thinly.
- Depth: Cover the seeds lightly with compost and water them gently.
- Light: Place the trays in a bright, warm location, but out of direct sunlight.
Transplanting Leek Seedlings: A Crucial Step
Once the seedlings have developed two or three true leaves, they are ready for transplanting.
- Hardening Off: Before transplanting, gradually acclimate the seedlings to outdoor conditions by placing them outside for short periods, starting with a few hours each day.
- Spacing: Space the seedlings 15-20cm apart in rows that are 30-40cm wide.
- Planting Depth: Plant the seedlings up to their necks in the soil, ensuring the base of the leek is buried.
- Watering: Water the seedlings thoroughly after planting.
Leeks and Their Love for Rich Soil
Leeks thrive in fertile, well-drained soil. The RHS recommends incorporating plenty of organic matter, such as compost or manure, into the soil before planting.
- Soil Preparation: Dig over the soil to a depth of 30cm, removing any weeds.
- Amendments: Add a generous amount of compost or manure to improve soil fertility and drainage.
- pH: Leeks prefer a slightly acidic soil with a pH of 6.0-6.5.
Providing the Right Care: Water, Sunlight, and Protection
Once your leeks are planted, you need to provide them with the right care to ensure healthy growth.
- Watering: Leeks need regular watering, especially during dry spells. Aim to keep the soil moist but not waterlogged.
- Sunlight: Leeks prefer a sunny location, but they can tolerate partial shade.
- Protection: In colder regions, protect your leeks from frost by covering them with fleece or straw.
Harvesting Your Leeks: A Culinary Celebration
Leeks are typically ready for harvesting between late summer and early winter. The best time to harvest them is when the stems are about 2-3cm in diameter.
- Harvesting: Cut the leeks at the soil level, leaving a small amount of the stem attached.
- Storage: Store leeks in a cool, dry place for up to several weeks.
Beyond the Basics: Troubleshooting and Tips
While growing leeks is generally straightforward, there are a few common challenges that you may encounter.
- Pests: Leeks can be susceptible to pests such as leek moth and onion fly. Use organic pest control methods to deter these pests.
- Diseases: Leeks can also be affected by diseases such as leek rust and downy mildew. Ensure good air circulation around your plants and avoid overcrowding.
- Blanching: For a milder flavor and a more tender texture, you can blanch your leeks by covering the stems with soil or a cardboard tube.
