Re fungus gnats, I went to Nunhead gardener today and one them told me it’s worth trying sticking some match sticks into the soil to try get rid of them. I did a quick google and it seems a sound suggestion. Gonna give it a go.
I managed to get rid of these with hydrogen peroxide solution which I added to the watering can for a couple of weeks. It got rid of the soil baddies and is non-toxic as it breaks down into water + oxygen.
