Iron, man.

Where are you when we need you?

During the rapid growing months of January and February, plants need to be able to grow to their full potential to be as in as healthy a state as possible to “weather” the winter months. Winter is always coming.

One micronutrient which is essential to help drive photosynthesis is Iron. At this time of year, we like to make sure that iron and nitrogen levels are optimal.

When you’re pumping iron, it’s not always about the weight.

While a system may require nitrogen levels of 9 to 22 grams per m2, it would only need about 0.17 grams per m2 of iron. If you take those few grams out of the system, the plants ability to create chlorophyll fails. Although plants and grasses acquire iron from the soil differently, its absence can be observed similarly.

Leaves will turn yellow around the veins while the veins themselves are green. Besides being impressive, plants that are a beautiful green colour are also healthy and vigorous, and likely to ward off any weeds, pests and diseases that come along.

Am I getting it right?

If you’re watering your entire garden properly but it’s pale green or yellow instead of dark green, your plants are most likely nutrient deficient. Yellow lawns generally lack key nutrients such as iron and nitrogen. This will lead to growth problems, including chlorosis, a condition that occurs when the green chlorophyll in the grass leaf tissue doesn’t develop. Chlorophyll fails to be produced when there is a lack of iron in the turf. A little iron deficiency, lawns will yellow, with major iron deficiency, grass can perish, chlorosis. It’s worth noting that iron and nitrogen deficiencies can happen simultaneously.

The irony

This is not the only mineral or nutrient which can cause similar discolouration.
