I got some strawberry plants off a work colleague a couple of years ago.
Last summer I only got about a dozen(!) berries so this year I got a big
strawberry pot, planted last years plants and bought more to fill all the
holes. At this point there is hoardes of leaves and quite a few shooters
sprouting out but there were not so many flowers.

Does this mean that, again, there will not be a decent crop or is there
anything I can do now to increase the yield?

TIA
