''A high nitrogen fertilizer, such as one designed for citrus trees, is best fed monthly between April and September. Withhold fertilizer during autumn and winter months. Yellowing leaves indicate the need for either water or fertilizer.'' (https://www.gardeningknowhow.com/edible/fruits/lemons/growing-meyer-lemons.htm)
