I have many different varieties of Citrus trees growing in my greenhouse including Tropical Mandarin Orange Citrus Tree’s, Tropical Lime Citrus Tree’s, Tropical Lemon Cheena, Tropical Calamansi Calamondin Philippine Lime and Tropical Lime Lemon Cocoracha.
They are all around 18 months old and for their first winter they were in a greenhouse that never dropped below 6 degrees C. This year they will be in an unheated greenhouse over the winter so I hope they survive.
Here are some pictures of ones that I have potted up: -

Here are some pictures of them when they were younger: -
