Lemon Tree (Citrus limon): Indoors, provide at least 4 hours of direct sunlight, a night temperature of 50-55° F, and a day temperature above 68° F. During the fall and winter, allow the soil to dry slightly between each watering. Flowering occurs indoors from mid-winter to early spring. Pollinate the flowers by allowing a fan to blow across the plant or by gently shaking it each day. Thin the fruit clusters to leave only 2 to 3 lemons per cluster.

The plant can be moved outdoors for the summer, where it should be gradually exposed to stronger sun over a period of 4 or 5 days to prevent sunburn. Water

every few days, depending on the weather, to keep the soil evenly moist. From early spring through late summer, use a water soluble fertilizer, such as Algoflash for Flowering Plants or Miracle-Gro, according to label directions. Prune through the summer to keep the plant to the desired size. Repot as needed, using a good brand of packaged potting soil and a pot that is few inches larger each time. Zones 9-10.
