Q.Pelargoniums
Is it ok to dig up my pelargoniums and over winter them in my potting shed. Its a bit dark because of the trees, but I don’t have any room in the house for them

Yes, I think you can overwinter them in your shed as long as it is fairly air-tight and stays above 0 Celsius. Pot them up and let them go dormant; do not water while dormant. Starting late winter/early spring keep an eye on it because it will miraculously send out new shoots. Resume watering and put it where it gets sunlight. The linked article discusses different ways to over-winter them. https://www.gardeningknowhow.com/ornamental/flowers/geranium/how-to-save-geraniums-over-the-winter.htm
