Four Seasons lemon tree not flowering.
My lemon tree, Keith, is thriving in a cool conservatory and has benefited from a few seaweed extract drinks during the summer. However, he’s showing absolutely no inclination to flower. I’m only watering with rainwater ever 10 days or so, when the soil is dry to about 4cm deep. I’ve had him a couple of years and when he first arrived, was full of bud and baby lemons, so I know he can do it. Because Keith is a Four Seasons, I assumed he would be producing something, even in the winter.
