Roasted horn: a classic in organic gardening for controlled growth

Roasted horn CP Jardin is a natural organic fertilizer derived from animal materials, rich in slow-release nitrogen. Particularly suited to trees, shrubs, roses, or potted plants, it nourishes the soil deep down while promoting steady growth without excess.

Roasting helps slightly speed up nutrient release, making this fertilizer effective in the short and medium term. Unlike crushed horn (slower), it acts more quickly while preserving the soil’s microbial life.

Used as a base dressing or for maintenance, it supports plant establishment, root development, and plants’ natural resistance to stress, diseases, or pests.

Why use roasted horn CP Jardin?

✔ Rich in proteins: promotes long-lasting plant growth

✔ Gradual, sustained action, with no risk of scorching

✔ Ideal fertilizer for trees, hedges, shrubs, beds, roses

✔ Compatible with container growing as well as in-ground cultivation

✔ Easy maintenance: simple to spread, no lingering odor

Did you know? 🌱

Horn is one of the oldest fertilizers used in traditional gardening. It naturally releases nitrogen over several weeks, which avoids the “quick boost” that can sometimes be harmful with fast-release chemical fertilizers.

Directions for use

1 handful = 30 to 40 g

🌿 Balconies and terraces

Planting: 70 g per 10 liters of potting soil
Maintenance: 35 g / 10 liters of soil, spread on the surface, lightly scratch in and water

🌳 In-ground

Planting trees or shrubs: 160 to 320 g per plant depending on size. Mix into the backfill soil of the planting hole
Note: for a slower release, choose crushed horn
Annual maintenance: 50 to 120 g / m² depending on soil richness. Spread on the surface, lightly scratch in and water

Roasted horn vs Crushed horn: which should you choose?

Criteria	Roasted horn	Crushed horn
Origin	Animal proteins (horns) heated at high temperature	Animal proteins (horns) dried and crushed
Speed of action	Medium – gradual action over a few weeks	Slow – diffusion over several months
Ideal use	Maintenance, quick establishment of plantings	Long-lasting base dressing
Plants concerned	Trees, shrubs, beds, potted plants	Fruit trees, roses, hedges, vegetable garden
Season of use	Spring, summer, autumn	Autumn or winter (soil preparation)
Risk of scorching	Very low	None
Nitrogen (N) release	Faster thanks to roasting	Very gradual
Maintenance or planting?	Versatile (maintenance + planting)	Mainly planting / base dressing

💡 In summary:

Roasted horn = faster action, ideal for maintenance and regrowth.
Crushed horn = slower action, perfect for long-term base fertilization.
