May: Early spring greens

Nettle, ground elder and spruce tips signal the start of the Nordic season. Timing the first harvest defines quality for the entire spring.

  • Harvest in the morning to keep aromas bright and let plants recover during the day.
  • Freeze or turn spruce tips into syrup while fresh to lock in vitamins and essential oils.
  • Keep a harvest log and double-check forestry notices for planned cuttings.

July: Opening of the berry season

Bilberry ripens on sunny heathlands, cloudberry on mires and crowberry on the rocks. Rotate routes weekly to avoid overharvesting.

  • Walk the same spots weekly – weather swings ripen berries unevenly.
  • Maintain the cold chain in the field using food-safe containers and ice packs.
  • Process part of the yield into juices or pastes to balance storage capacity.

Week 22: Northern Ostrobothnia picks

Early summer crops shift from riverbank groves to shaded spruce forests. Moisture and night temperatures set the rhythm.

  • Get landowner permission before collecting spruce tips or resin for commercial use.
  • This week’s sure finds: fireweed shoots, young dandelion leaves and coastal reed sprouts.
  • Dry footwear and gear carefully after each outing to prevent mould growth.

Late June archipelago guide

Sea breeze ushers in the seaweed season and fish schools followed by seals. Make the most of coastal ingredients responsibly.

  • Harvest bladderwrack only from clean waters and monitor algae bloom warnings.
  • After the Baltic herring spawn, perch returns to nets – experiment with small mesh traps.
  • Dry seaweed for a seasoning mix together with spruce tip powder and juniper berry.

  • Use a shared coding system (for example Willit product IDs) to track batches.
  • Store the logs in the cloud and invite partners – fewer emails, more transparency.

Sustainable pricing in wild food

Pricing balances labour, logistics and demand without overharvesting. The article walks through a durable margin calculation.

  • Include travel time, post-processing and certifications when calculating costs.
  • Agree on minimum volumes and quality standards in writing before the season.
  • Schedule recovery breaks for harvest sites so nature and clients stay in sync.
