I have strawberries in self watering baskets in my polytunnel. This is the 3rd season in the tunnel but I have grown like that in a greenhouse for many years previously. I always grow everbearers and keep my plants going for 2 seasons. I currently have Mara de Bois and the plants are in their first year from runners last year. My last lot of first season plants, also from runners, cropped continuously from the end of May through to October. The following year they produced a big flush then lots of runners, there was some fruit on the runners. Starting with new plants again this year I was anticipating continuous cropping but they started producing runners almost straight away. I kept taking them off and had a rather underwhelming crop of very nice fruit. There are no further flowers coming on the plants so I'm letting the runners grow now in the hope of some more fruit. The temperatures in the polytunnel have been rather excessive over the last 4 or 5 weeks, that's not usual here. My max / min thermometer goes up to 50° and its been up there several times. Could this have stressed the plants and made them go into survival mode? Or does anyone have any other thoughts? I think I will buy some new plants for next year.
