let there be good night temperatures
One of the biggest problems with growing tomatoes in Sweden is the possibility of a sudden night temperature drop. Around this time of the year, we could have a high of 20°C and then a low of 3°C. Tomato plants are not fans of low temperatures. That also depends on the size of the plant as well as where you have them. I go with the 7°C as my minimum mark.
According to the weather forecast, lows are supposed to be above 8°C after Sunday. I think it’s time to introduce my tomatoes to their permanent home.
