I have many packets of seeds for various flowers, mainly hardy annuals & perennials.
The packets all say sow Jan-Mar but they talk about propagators and keeping at 15-20C before planting out. I haven't the room to do this, and I don't own a propagator. Can I just sow the seeds straight into the ground or pots once the weather outside is approaching 15C? Or will that not work?!
If I sow them outside now, presumably the ground will be too cold and nothing will happen?
