Timely Tendings: Prevent yellowing citrus leaves with minor elements

Apply minor elements to citrus trees to prevent yellowing of leaves

Citrus leaves that are yellowing around the edge and distorted may be lacking a minor element. Apply minor elements to your citrus trees either as a foliage spray or as a drench to the soil. Carefully mix sprays to apply only the recommended amount as stated on the product label. Minor elements will correct yellowing due to deficiencies of iron, magnesium and manganese, and will also supply copper, zinc, boron and other needed elements.

Citrus greening disease will often look like a nutritional disorder; learn more about the symptoms here:

Citrus fruit splitting and fruit drop may be a problem during the fall. This is a physiological problem that could be more pronounced just after a period of moisture stress followed by heavy rains. Splitting and drop will usually not be a serious problem if the trees are well cared for and furnished with adequate nutrition and irrigation.
