There are a number small black flies on the plants, what are they?
These are Scarid flies and thrive in the warm, humid indoor growing conditions found in all nurseries and it is common for them to arrive with your plug plants. Our compost is treated for such pests however it’s very difficult to avoid whilst in transit and you may find a few in your plants. Don’t worry, these should not affect the health of your plants. Once planted out the flies tend to disappear in seek of a more comfortable environment. If you have bought indoor plants, leave them outside in their trays during the day time for about a week before potting up and the flies should have abandoned your plants.
