Spring is Here

Spring arrives slowly here in the UK, sometimes more whisper than shout. The soil feels heavy with last season’s echoes and a quiet hope for the first seed to break ground.

That’s the thing about spring sowing though: the feeling of beginning. And the steady, simple work of it.

Starting seeds in spring means leaning into that moment — the thaw, the lengthening days, the shift in rhythm. It’s about knowing which seeds need a gentle start indoors, and which prefer the rawness of chillier soil.

At Herboo, we believe a garden can begin anywhere this season — windowsills, covered trays, small patches in the ground. That first sowing in March or April sets the tone.

Why Spring Sowing Matters in the UK

Unlike warmer climates, our spring is a patient one. Frosts surprise us, sun doesn’t always shine, and the soil takes its time to warm. So sowing at the right moment — and with the right seeds — means less frustration and more delight.

Think early peas and broad beans outside in March, while indoors your tomatoes and peppers are readying for the stretch. April brings a broader palette: carrots, lettuce, and the first blooms of cosmos to brighten the border.

What to Sow in April

Eager to move outdoors? April’s pace picks up, with more direct sowing and pricking out seedlings from your growing trays. Find out more in the April guide.

Starting Seeds Indoors vs Direct Sowing

A tricky balance. Indoors you control warmth and light; outdoors you trust the seasons. Both have their place. The secret is timing and patience.
