Q.

Browning leaves on a cherry laurel

The tips and edges of the leaves start by shrivelling, whilst still green, then turn crispy and brown around the edges. They look and feel burnt. Does anyone know how to stop this or make them better?!

This will be considered a severe fungal infection. This is usually caused by wet conditions that remain too wet for far too long, allowing the infection the perfect environment to reproduce.

Prevention is going to be your best defense, as this can become quite tedious to treat. Obviously, you cannot control the weather, so you may have to defend against it!

DOLOMITIC LIME and WETTABLE SULFUR, when used together, will prevent, and kill most infection. You will want to use about a cup of Lime, and about a teaspoon of sulfur.

If you cannot find these in your area, then you will want to check online, as most online nurseries will ship with no issues.

You will also want to treat the above-ground portions of the plant with a fungicide as well. This article will help: https://www.gardeningknowhow.com/garden-how-to/info/using-fungicides-in-garden.htm
