This may not be the case in the USA, Australia etc but whenever I buy strawberries they are disappointing in that they are not sweet at all and only the addition of sugar makes them reasonably good.
Only once I had strawberries that were sweet as they should be, I believe they were from Scotland, otherwise they are just colour they look good to the eye but they are not tasty (aren't they like the Watchtower Society?)
Does anyone know of specific sweet varieties that can be grown at home?
