Morning glory, yellow leaves green veins.

Question

If its lacking iron, what would i need to give it? Or anything else.

Answer 1

This is rare for the morning glory to have deficiencies. What are the conditions like in the soil, and how much light does it receive?

This appears to be a calcium deficiency, which would not be common outdoors. It could likely be paired with an iron deficiency, as well. Could your soil be contaminated with an infection? Has it been overly wet recently? These could cause infections.

Alternatively, it could be a simple pH issue. The soil could, simply, be way to alkaline to support proper nutrient uptake. I will need to know more about the soil to be able to say.

Luckily, iron sulfate and dolomitic lime will take care of most of those issues. and is a very good thing to keep around, anyway.
