It's best to stick with seed-raising mix for starting seeds to ensure they get off to a healthy start! Potting mix contains controlled or slow release, long-term fertilisers that are suitable for established plants, while seed-raising mix contains short-term controlled release fertilisers suited for seed germination. Potting mix typically contains a higher rate of fertiliser than can be harmful to young seedlings.

This combination ensures light, free-draining mix ideal for seedling root growth. It also includes Osmocote Exact Mini® granules, which provide nutrients for up to 12 weeks without burning seedlings. Added gypsum, calcium, and magnesium support strong roots, and wetting agents improve moisture distribution, so the mix does not dry out. 

Daltons Premium Seed Mix additionally includes Trichodry® to protect against diseases and provide beneficial fungi like Trichoderma (the good guys).
