Medium_magnolia-leaves My Magnolia leaves turning yellow with green veins.

The Magnolia is planted on the ground. I have noticed the the new leaves that are growing are looking yellowish with green veins. Some leaves even have brown spots. But older leaves are green and healthy. This was planted as part of the landscaping by my builder. It's been 6 months. Please advise how can I rectify this? Thank you.

Answer: Hi Joya,
Thank you for sending the photo. It looks like your magnolia is deficiency in a couple of elements. An iron deficiency presents itself as the leaf being yellow in the background with prominent green viens throughout the leaf. A zinc/manganese deficiency has similar leaf discolouration with yellowing and fine green lines appearing on the leaf.

If you haven’t as yet fertilised your tree in the past couple of months, fertilise now before the cold weather sets in. You might also like to apply a Yates product called Trace Element Chelates. This product will correct a range of micro nutrient deficiencies such as iron, manganese and zinc. This is an easy to use liquid product that is recommended as a foliar application which delivers nutrients directly to the deficient leaves for faster results. Apply this product every 4-6 weeks or when needed.

In addition, give your plant regular applications of a seaweed solution to assist in developing a stronger root system which will enhance the health of the plant in general.
