When you can put out their chiliplantor in non-heated areas is both kind and what you want to achieve with their cultivation. Many Capsicum chinense is very sensitive and you can actually lose the whole chiliskörden if you are unlucky. For my part, I believe that one should wait until around midsummer, when the risk of night frost is not so great. According to me you can earn quite a lot of waiting and let the plants grow indoors in the heat.
Here are some facts and what may happen at different temperatures.
Chili is a heat-consuming plant and a good cultivation temperature is between 20 – 25 degrees.
For optimal vegetative growth and good fruit development, it is important to avoid sharp temperature differences between day and nattemperatur. It is common with floral waste at
large temperature differences between day and night.
At an air temperature below 18 º C and above 35 C impaired production of leaves and fruit. at temperatures above 25 º C, there is a great risk that the plants repels flower buds and fruktkart.
Soil temperatures below 15 ° C leads to lower growth and also to blomfall.
Many chilisorter be damaged already at an air temperature below 13 degrees and growth ceases entirely at soil temperatures below 10 º C and above 35 º C.
At an air temperature below 10 C so, some varieties have so much damage that it does not survive
PS. Here in Sweden, we of course expect to get some periods even in summer with chiliplantor low temperatures but it wont just be temporary dips so it should not have any greater significance if not the low temperature will be long-lasting. I usually cover my plants with filter cloth or dyrligt if alerted to low night temp.
