Lemon / Orange / Kumquat

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, according to label directions. Pinch as needed to control the size of the plant. Repot as needed, using quality potting soil and a pot that is few inches larger.
