Deficient Citrus

Healthy, well fed citrus trees have the best chance to provide us with buckets of home grown delicious juicy fruit.

Regularly using a complete fertiliser specially formulated with the right proportions of the 3 main elements – nitrogen, phosphorus and potassium – such as Yates® Thrive® Citrus Liquid Plant Food, is an important step towards having happy citrus trees. Citrus also require ‘trace’ elements in small amounts for total plant health.

Some soils and potting mixes are deficient in these trace elements, or the soil pH makes it hard for plants to access them. So in addition to using complete fertilisers we may need to give citrus a helping hand and provide them with additional trace elements.

Two common trace element deficiencies of citrus are iron and magnesium. It’s simple to correct both these deficiencies with specially designed trace element liquids.

Iron (Fe) – the main initial symptom of iron deficiency is the young citrus leaves becoming pale with the veins remaining dark green. Iron is involved with photosynthesis, so plays an important role in tree health and productivity.

Iron deficiency is particularly common in alkaline soil (soil with a pH of greater than 7) as the iron becomes unavailable to plants. Yates® Leaf Greener Iron Chelate is a fast acting liquid that corrects iron deficiency. Applied as a foliar spray, it delivers iron directly to the deficient leaves for faster results.

Magnesium (Mg) – a magnesium deficiency shows up as a dark green V shape at the base of older citrus leaves, with the leaf tips becoming increasingly pale.

Magnesium deficiency can lead to trees dropping their leaves and overall tree health and the harvest will suffer. Yates® Leaf Greener Magnesium Chelate is a fast acting, concentrated form of liquid magnesium that is sprayed onto citrus leaves to correct magnesium deficiency.

Both Yates® Leaf Greener Iron Chelate and Yates® Leaf Greener Magnesium Chelate stick firmly to the foliage and are rainfast in 2-3 hours.
