Overwintering a Meyer Lemon: Light Requirements

Meyer lemons crave maximum light. A greenhouse is ideal. An unheated basement, even with a large window, provides insufficient light (typically under 1,000 foot-candles vs. 10,000+ outdoors). A practical indoor solution: surround the tree with four clamp lights fitted with 100-watt equivalent CFL bulbs. Without adequate light, the tree will shed leaves by mid-winter. Move it outdoors in May for rapid recovery.
