If you planted an “ever-bearing” type (rather than a “June-bearing”) they tend to produce fewer berries over a longer period of time. Although fewer doesn’t usually mean none ;)

It could also be that strawberries produce best in their second year… maybe patience is the answer? I also recommend snipping off any runners (those long shoots strawberries send out to make new babies) in order to force the plant’s energy into fruit production.

Strawberries also don’t like full shade, or competition from weeds.

Hope this helps!
