Don't you love the scent of lemon flowers? When in full bloom, the scent is intense and sweet. And, I love to watch tiny lemons that form after the pollination. A year ago, I cut branches back to initiate new branches growth and keep it within reasonable size.
Namely, I grow it in the pot because it has to overwinter inside the house. Carrying the pot inside is not an easy task. In summer I place the lemon on bright sunny spot allowing bees to pollinate the flowers.
This year it needs re-potting and will do it it in September. It needs slightly acidic soil, moist but well drained. And, I fertilize it every six month with pelleted organic fertilizer.
