What month is it safe to plant flowering plants outside in Sweden?
Have planted some geraniums and daisies that have succumbed to frost/freezing!
Suggested Project Book
Plant only when you know that you are done with the frost and freezes for good. There will always be the risk of late ones that can't be helped. Last year we had snow in early may! That is the hazards of living in the north. No matter how hard you try, there will always be some kind of oops in the weather. If you know you have a cold forecast coming cover your plants and they may survive without a problem.
The best is to make sure that the frost has for sure passed before planting outdoors, have fun!
