Cold areas or regions with continental climate are perfect for later flowering varieties, due to their need of colder temperatures. Late flowering and cold temperatures are essential for the plant to protect itself against late frosts that may jeopardise its flowering and consequently its fruiting.
For example, in case of a late April frost the varieties with fruitlets, that have recently bloomed or where flowering is still ongoing may suffer very serious damage even at temperatures between of -2 / -3° C.
