This guide will walk you through the steps of soil preparation, sowing, maintenance,
and incorporation to maximise the benefits of this diverse blend.
How to use the Mix
Here is one Step-by-Step guide with how we like to use cover crop ourselves. There are many ways to incorporate cover crop so you may need to make considerations based on location and climate etc. This process can be applied when starting new garden beds out or applied in between the flowering and fruiting crop cycles.
Soil Preparation
Begin by clearing the planting area of any existing vegetation and debris. Very lightly (less is more we often feel) till or rake the soil to create a smooth seedbed, ensuring good seed-to-soil contact for optimal germination.
Sowing
Broadcast the seeds evenly across the prepared soil. For best results, cover the seeds with a thin layer of soil or compost. This can be done by lightly raking the surface or using a seed spreader. Ensure the seeds are well-distributed to avoid overcrowding and to promote even growth.
Watering
After sowing, water the area thoroughly to ensure the seeds are well hydrated. Maintain consistent moisture until the seeds germinate and the plants are established. This may require daily watering, especially in dry conditions. Consistent moisture is crucial for the early stages of growth.
Growth and Maintenance
Allow the cover crops to grow for 8-12 weeks. During this period, monitor the growth and ensure the plants receive adequate water. The mix will provide excellent ground cover, suppressing weeds and improving soil health. Regularly check for any signs of pests or diseases and address them promptly.
Incorporation
Before the cover crops set seed, mow or chop them down at their peak biomass, just before flowering. This process adds organic matter and nutrients back into the soil, enhancing its fertility and structure. It also provides mulch on top of the soil and will be perfect to plant established seedlings into straight away or allow to rest and breakdown in the next optional step.
Resting Period
You could also let the soil rest for a few weeks to allow the green manure to decompose. During this period, the organic matter will break down, releasing nutrients and improving soil structure. After this resting period, your soil will be ready for planting the next crop.
Additional Tips for Success
Timing: Plant the mix during appropriate seasons for your region, typically spring and fall, to ensure optimal growth conditions. Also think about how long it takes for cover crop to grow and be chopped in before your next season is upon you. Think about starting seeds in seedling trays ready to transplant into the rich soil.
Soil Testing: Conduct a soil test before planting to understand its current nutrient status. This can help you tailor additional amendments if needed and apply well in advance to allow worms and microbes to decompose them into food for your plants.
Rotation: Rotate the cover crop mix with your main crops to prevent disease build-up and maintain soil health. This also provides nutrients evenly and generally allows a more balanced soil over time. This means there is abundance of each nutrient for when the time allows. This goes for flowering and fruiting crops as well and considering which plants are using which nutrients each season.
Mulching: Use the chopped cover crop material as mulch if you don’t till it in immediately. This can provide immediate soil cover and reduce erosion. We use this method all the time, especially when having cover crops growing in amongst our flowering or fruiting crops. Also when in turn these crops also finish for the season we can chose to prune or remove entirely and chop down into the mulch layer.
Benefits of the Mix
Soil Fertility
The legumes in the mix naturally fertilise the soil by fixing atmospheric nitrogen, reducing the need for chemical fertilisers. This enhances the nutrient content of the soil, supporting healthier plant growth.
Weed Suppression
The dense growth of these cover crops smothers weeds, reducing competition for nutrients, light, and water. This minimises the need for herbicides and manual weeding.
Soil Structure and Erosion Control
Grasses add organic matter, improving soil structure and preventing erosion. They also enhance water infiltration and retention, creating a more resilient soil environment.
Pest and Disease Management
Mustard and radish suppress soil-borne pests and diseases, reducing the need for chemical pesticides. This promotes a healthier soil ecosystem and reduces crop losses.
Biodiversity and Soil Health
The diverse mix encourages a healthy soil ecosystem, attracting beneficial insects and microorganisms, and promoting a balanced and resilient soil environment. This biodiversity supports long-term soil health and productivity.
Using our 15 Seed Green Manure Cover Crop Mix is a sustainable way to improve soil health, boost fertility, and manage weeds and pests naturally. By following these detailed steps and tips, you’ll create a thriving, productive soil environment that will support your crops for seasons to come. Embrace this sustainable approach to agriculture and reap the benefits of a healthier, more fertile soil.
