NO, there is a peak season for each, sometimes extendable with succession plantings, also perhaps by the use of hoophouses(polytunnels in english!) Only supermarkets have strawberries 365 days.
Every location will have differing climatic conditions which are the dominant influence, be it frost, day length,light level,sunshine, rainfall, etc.Each crop will have its own requirements and success will be related to optimising conditions. You need to research what works in your climate, perhaps you have a neighbour with’ green fingers’?
