Last year my lettuce were attacked by lettuce root aphids (like normal aphids but they attach to the roots instead of leaves). I’m told they are a fairly rare pest but once they are in the soil you’re pretty much stuck with them unless you take action. Some of the lettuce varieties I chose last year (Little Gem, and Lobjots Green) seem to have little will to fight the aphids. While others (Salad Bowl, Four Seasons and Webs Wonder) seem to be able to withstand the attack to some extent. Although, later in the season the pests got to be too much even for the fighters and made their leaves go limp and yellow. I absolutely love salad in the summer and can’t let anything jepordise my leisurely summer lunches with fresh crunchy salad. So I’ve done a bit of investigating and have found that there are two varieties of lettuce that have resistance to lettuce root aphid. They are Mohican and Sunny. They’re available in Moles Catalogue but since they are a trade supplier you can only buy them by the 1000’s! In the photo you can see my attempts at growing early lettuce this year – too leggy and not enough light I think.
