The Only Flower Seeds You Need to Sow in March – 7 Fool Proof Blooms for a Show-Stopping Summer Garden

Summer garden filled with zinnias, achillea, alliums, verbascum and cosmos, with a glasshouse and willow obelisk and arch.

This month sees the arrival of longer days and warmer weather, and there is a feeling that summer is definitely on the way. So my thoughts always turn to the best flower seeds to sow in March, and the ones I have come up with are fool proof.

Sowing my own seeds is always rewarding but especially so when it means filling my garden with all my favorite flowers. There is a huge range of plants that are quick and easy to grow in this way, and growing from seed is a much more affordable option than buying young plants at the garden center.
