Suppressing weeds on the allotment

The Use of Old Carpets and Cardboard for Weed Suppression

Richard begins by discussing the common practice of using old carpets in gardening, particularly for weed suppression. However, he highlights the potential issues associated with this method:

• Chemical Concerns: Carpets may contain harmful chemicals that can leach into the soil, affecting plant health.
• Damage to Equipment: Carpets left in the ground can cause damage to gardening machinery, making them a less desirable option.

Instead, Richard advocates for the use of cardboard as a biodegradable alternative. Here’s how you can effectively use cardboard in your garden:

• Preparation: Remove any non-biodegradable materials, such as Sellotape, from the cardboard. Wetting the cardboard can make this process easier.
• Application: Lay the cardboard over empty garden beds to suppress weeds. As the cardboard breaks down, it enriches the soil with organic matter.

Benefits of Mulching with Woodchip and Seaweed

Richard emphasizes the importance of mulching in maintaining a healthy garden. Mulching offers several benefits:

• Moisture Retention: Mulch helps retain moisture in the soil, reducing the need for frequent watering.
• Weed Suppression: A thick layer of mulch can prevent weeds from germinating and taking over your garden.
• Soil Improvement: As mulch decomposes, it adds valuable nutrients to the soil.

Richard shares his experience with two types of mulch:

• Woodchip: Often delivered to allotment sites for free, woodchip is an excellent mulch that improves soil quality as it decomposes.
• Seaweed: Collected from the beach after storms, seaweed is rich in nutrients and has been historically used in coastal gardening.

Collecting Leaves for Mulch and Compost

Another valuable resource Richard discusses is leaves, which are often considered a nuisance in public spaces. Here’s how you can make the most of fallen leaves:

• Mulch: Use leaves as a mulch to protect plants and suppress weeds.
• Compost: Add leaves to your compost heap to create nutrient-rich compost.
• Leaf Mold: Create leaf mold by collecting leaves in a bin or bag and allowing them to decompose over time. Leaf mold is an excellent compost for seed sowing and growing specific plants like parsnips.

Effective Mulching Techniques

Richard concludes his gardening segment by emphasizing the importance of effective mulching. Here are his key tips:

• Quality Over Quantity: It’s better to mulch half a bed well than to spread a thin layer over an entire bed poorly.
• Compost as Mulch: While compost is the best mulch, save it for when it’s most needed to maximize its benefits.

Chef Scott's Recipe Segment

In the latter part of the episode, chef Scott introduces a delicious recipe for a sweet potato and spinach lasagne with a hint of chili. This recipe not only showcases the versatility of sweet potatoes but also encourages listeners to grow their own produce.

Scott encourages listeners to try growing sweet potatoes, highlighting their rewarding nature. Here are some tips for growing sweet potatoes:

• Climate: Sweet potatoes thrive in warm climates with plenty of sunlight.
• Soil: Plant them in well-drained, sandy soil enriched with organic matter.
• Watering: Keep the soil consistently moist but not waterlogged.
• Harvesting: Sweet potatoes are ready to harvest when the leaves start to yellow and die back.

Creating a hot bed.

A project Richard has wanted to do for a while is to build a hot bed. A hot bed simply uses the heat from the composting process to warm up a bed and any plants in that hot bed can thrive.

This is a simple build using an existing bed, simply needed the addition of a cover and fresh compost material.

• Use fresh chicken or horse manure, including straw and wood chips for maximum heat.
• Top up regullery
• A cover helps trap the heat for the benefit of the plants.

Conclusion

This episode of the Veg Grower Podcast offers a wealth of knowledge on sustainable gardening practices and culinary creativity. Richard’s practical tips on using biodegradable materials and effective mulching techniques provide valuable guidance for gardeners. Meanwhile, Scott’s delicious recipe for sweet potato and spinach lasagne inspires listeners to incorporate homegrown produce into their meals.
