Dear Member,
🌱 Green Manures & Soil Care
Now that you are harvesting your flowers and vegetables, you may find gaps of bare soil. If you have access to manure, you may be planning to dig some in. If not, green manures are an excellent alternative.
Green manures cover bare soil to prevent weed growth, improve fertility, increase humus content, and enhance soil structure. They are especially useful in autumn after crops have been lifted. Choose species based on the job required and the length of time the area will be unused.
Some species are not winter hardy, meaning they naturally break down over winter and can be cultivated in spring without special digging‑in.
🌾 Types of Green Manure
🌸 Buckwheat
- Deep‑rooting: breaks up subsoil
- Produces lots of growth → boosts humus
- Attracts hoverflies (great for greenfly control)
- Fast to establish → excellent weed suppression
- Dig or rotavate in before frosts
🌱 Field Beans
- Nitrogen‑fixing
- Sow in rows 20cm apart, 10cm between seeds
- Winter hardy (Sept–Nov sowing)
- Dig in early spring (March–May) before flowering
🌾 Grazing Rye
- Not the same as ryegrass
- Extensive root system → improves soil structure
- Dig in during spring before flower heads form
🌼 Phacelia Tanacetifolia
- Quick to establish
- Excellent weed suppression
- Winter hardy → sow in autumn for spring digging‑in
- Adds humus and improves soil fertility and structure
🍃 Winter Tares
- Fast‑growing annual vetch
- Nitrogen‑fixing and winter hardy
- Best weed suppression when mixed with Rye
- Sow July–September
- Dig in during spring before flowering
