The cropping season

In the UK, strawberries can crop from March through to December. The earliest crops are generally harvested under glass in Southern England in early April although additional heat and night-break lighting can bring crops into fruit as early as March. The season continues under closed fixed polythene tunnels, followed by field-grown crops under French and Spanish tunnels, lay-flat fleece or polythene film. The traditionally grown unprotected field crops then become available in June and July.

Extending the season beyond June/July can be achieved by employing a number of growing systems: 

  • Using deep straw or white on black polythene to delay the established traditional crop.
  • Growing plants that have been cold-stored and which are planted and established on specific dates so that cropping is programmed to begin after the main picking season.
  • Growing everbearer varieties both outdoor and under portable tunnels to extend production through the late summer into the autumn.
  • Harvesting fruit from crops grown under fixed closed tunnels and glass. Fruit picking can continue under glass until December in Southern England.

Table 1 illustrates how the cropping season can be spread from March until December using different growing systems

Successful crops require careful pre- and post-planting management if you are to produce strawberries almost year-round.

Follow best practice when planting and establishing strawberry crops

Whether you're growing strawberries in tunnels or outdoors, you'll need to know the best methods to ensure the right timing of crops and to maximise yields.
