March 18 carries that unmistakable late-March tension: the year is visibly shifting, but the season has not fully declared itself yet. It is a date that invites observation — of weather, of light, of folklore, and of the garden’s first confident signals.

A season on the hinge

March 18 sits in that charged stretch of the calendar just before the March equinox, when the Northern Hemisphere feels poised between endings and beginnings. The light is lengthening, the soil is loosening, and even when the mornings still bite, the garden begins to act as though a message has already arrived.

Folklore, weather, and waiting

Across cultures, this part of March has long invited weather lore, seasonal sayings, and little rituals of attention. In Hungarian folk tradition, March 18 marks the first of three closely watched days believed to usher in milder weather. The old saying tells it beautifully: Sándor, József and Benedek arrive carrying warmth in a sack — a vivid image for that fragile turning point when winter still lingers, yet spring is suddenly imaginable.

There is also an intriguing echo in the Irish diaspora, where March 18 is associated with Sheelah’s Day, a lesser-known folk observance that lingers just after St Patrick’s Day. While very different in origin, it shares that same in-between quality: festive, transitional, and balanced on the edge of the brighter season.

What the garden is really saying

For the garden, this is less about certainty than readiness. Mid-March often signals that currants and gooseberries need attention, even if cold mornings have not fully disappeared. Pruning now helps shape an open, healthy framework, improves light and airflow, and prepares the plant for stronger fruiting later in the season.

Red currants reward careful thinning and the preservation of fruitful short spurs. Black currants behave differently, bearing much of their crop on younger shoots, so the aim is to encourage vigorous new growth. Gooseberries also benefit from a well-aired crown, especially if you want healthier plants and easier picking in summer.

A shared spring mood

In the Garden Almanac, March 18 becomes more than a date on the page. It holds a shared seasonal mood — a day when folklore, weather-watching and practical garden work all lean toward the same promise: not full spring yet, but the unmistakable sense that it is drawing near.
