Safflower Green Manure Seeds
Botanical Name: Carthamus tinctorius
Safflower is a hardy, deep-rooted annual widely valued in green manure mixes and broadacre regenerative systems. Known for its exceptional drought tolerance and ability to thrive in poor soils, safflower helps break up hardpan, improve subsoil access, and increase long-term soil resilience. Its vibrant flowers support pollinators, while its extensive root network enhances nutrient cycling, making it ideal for sustainable farming, rotational cropping, and soil-restoration projects.
- Deep taproot system penetrates compacted layers and improves water infiltration.
- Highly drought-tolerant, performing well in dry, marginal, and low-fertility soils.
- Helps mobilise nutrients from deeper soil layers for future crops.
- Bright flowers support bees and other beneficial insects.
- Ideal for green manure, soil conditioning, and rotational break crops.

When to Sow Safflower in Your Climate
| Climate Zone | Best Planting Time | Tips |
|---|---|---|
| Temperate | Spring–early Summer | Avoid cold soils; sow once frost danger has passed to ensure strong root growth. |
| Subtropical | Spring–Summer | Performs best when planted during warm, dry periods with good sunlight. |
| Tropical | Early dry season or cooler months | Avoid heavy wet-season soils where waterlogging may delay establishment. |
| Cool | Late Spring | Plant after the last frost; thrives in warming soils and increasing daylight. |
| Arid | Spring or after rain | Sow following reliable rainfall for best germination and early root development. |
