    Are they getting enough water? With the leaves losing color and curling up, you may need t just give them more water. Here are some pointers for watering containers:

    Hi, thanks for the advice, but I live in Sunny Scotland, and if anything they are getting too much water at the minute. Squirted them with some diluted fairy liquid and it seems to have helped, so will wait and see what happens.

    It sounds like they may have root damage, either from root rot or perhaps pests. Check the roots for damage, make sure that you have good drainage on the container. Also, as they are on the side of the container, make sure that where they are is not heating up in the sun and cooking the roots.

    Are you using fresh soil? It sounds like there may be a bacteria or fungus in the soil that is killing them.

    I would discard the soil or sterilize it and wash the containers with bleach before replanting.

    Traditionally lobelia looks bad in heat and too wet environments. It could be either or both, and powdery mildew could be present. Don't know how to control heat, except to provide shade in hottest part of the day. If it's too wet, keep out of rain. and if powdery mildew is present, this article should help: https://www.gardeningknowhow.com/plant-problems/disease/get-the-cure-for-powdery-mildew.htm
