Core guide
Follow the packet
Sowing time, depth, temperature and light needs differ between species. The seed packet is your first reference.
Fine, clean mix
Use fresh seed-starting mix. A thin covering of vermiculite keeps moisture even around seeds; perlite helps cuttings root in an airy medium.
Light and hygiene
Seedlings stretch in weak light. Use clean containers and avoid keeping the mix saturated to reduce the risk of damping off.
