Hello plant pros! As it's autumn in the northern hemisphere, I need some tips. Details: -I live in North America -It gets REALLY cold beginning in about November -It's decently dark nearly every day So my questions are: -Should I stop feeding my plants? When? -is this a good time to repot? Bigger? Smaller? -How can I keep them alive? In winter I don't expect thriving and actively growing. Thanks in advance!
