I read that it takes a year for Strawberry plants to mature and start producing a lot of fruit. In the first year, the plants yield some fruit, but it is the second year that they really produce.
That is why some people recommend pinching off all of the flowers during the first year.
I did not pinch off all of the flowers that last year. I just pinched the flowers in the first couple of months (see this blog entry)
Still, I am amazed as to how much more productive the plants are this year. I have see more Strawberries and Flowers at this time than at any one time last year!
Strawberry plants produce well for around 3 years. So hopefully I will have another couple of years of this kind of yield before I need to replace the plants.
