What was the fertilizer. Synthetic or organic. What makes you think they are dying. Please send close up pictures of the entire tree, the base, the trunk, stems and leaves
Hi Chuck, the fertilizer was called 20/10. Potato fertilizer. I'll attach photos, although there's not much to see, most of the plants are now devoid of leaves, and any that have leaves are already brown. Thank you for replying. Much appreciated

This is one of two things or both. Improper fertilization or lack of water. Improper fertilization is, in this case fertilizing a dry plant and then watering it in. Always water first, then fertilize, then water in the fertilizer. Very young fresh planted trees such as these take a lot of water. Even if your soil is clay you should deeply water the plant at least once a week. I would try to flush the fertilizer away by extensive watering. The fertilizer you used is a synthetic and can damage roots of a young tree. A laurel does need a small amount of nitrogen but 20 is way too strong. You want fertilizer numbers for laurels to be higher on the last two numbers such as 5-10-10. Anyway, all you can do now is try to undo the nitrogen burn by flushing. If the trees come back keep them well watered.
