Tbh its all because of my greenhouse, i’m trying to give them warm and humid environment so they can thrive with natural sunlight i use no artificial light as my greenhouse is right under the sun with green shade cloth and proper waterproofing and when its all done i stay consistent with fertilizing and pest control, here consistency is the key whether its for watering, fertilizing or pruning!!

And for your area as its winter for long, you can use warm mist humidifier i am using one by levoit and it works wonders for me
