I'm getting a Kumquat and shikuwasa soon because they're cold hardy for our winters and I don't have to worry too much about the plant dying from the cold (though I will protect it) but I prefer to plant these in full soil, not in containers in the greenhouse (because that's where I can plant whatever i want). My question is, will such citrus survive warmer summers? Often I have potted citrus that get dried out leaves when the sun shines and the temperature rises above 32 °C, even during heat waves inside the greenhouse it gets to 50 °C. The greenhouse is 4.5m long, 3m wide and 2.7m high, the sunny side has a shade cloth because the whole thing gets plenty of sun light anyway and has 4 windows and a double door. Naturally I open up everything completely when temps rise above 25 °C but I just want to make sure that I'm not making a stupid decision of planting these in the greenhouse. As to why I want them in full soil: - I prefer to limit the citrus in containers - Full soil has better moisture management and root development for long term - no need to hassle with giant containers in the later phases. I cannot plant them outside the greenhouse because we get too much rain and in winter I want to protect them a bit more from the cold, because they develop fruit in the months we get frost. Our winter temperatures usually float around -4 to -7°C but last winter we had an exceptionally cold one of -10°C. I was going to cover them up with a fleece cover regardless but still, the summer is worrying me more. I do not have the accommodation or space to place ventilation systems in the greenhouse. Only the 4 windows and double door to open up. Is it possible to plant those citrus in the soil in my greenhouse and how do I keep them from drying out given the above mentioned conditions? Or is it completely impossible this way? If so I can let them stay in the greenhouse (fully wrapped in) in winter and during the spring/summer etc I can put them outside.
