I have four Magnolia Kay Parris growing in a west facing garden bed. Three are looking good and growing strongly but one is slower growing with quite a lot of yellowing leaves. Have tried Seasol and Nitrosol but doesn't appear to have assisted

I know how annoying this can be when plants are all growing in the same spot and yet there will always be the exception where one doesn't perform as well as the others. It may just be that the magnolia with the yellowing leaves may not be receiving as much moisture as the others and therefore is not taking up the nutrients it needs to thrive and look healthy. Keep doing what you are doing by applying the seaweed solution on a regular basis. Check to see that the soil is moist and the water is penetrating and not running off the surface. Apply a mulch around the root system of the plant to protect those delicate feeder roots. Also check to see there are no pests present such as aphids, mites, mealybugs or thrips and if present, spray with Yates Nature's Way Vegie & Herb Spray Concentrate. When spring comes, feed with some Yates Dynamic Lifter Liquid Concentrate. It's a organically certified fertiliser, which contains seaweed, blood&bone and fish meal to help developing new roots and restoring healthy growth.
