Coreopsis pest problem and what to do about it
I recently took delivery of a mix of plant plugs from T&M recently, a special offer mixture of plants. I potted them up with some compost to let them get bigger before putting them in the ground. I also bought them into the house as my plastic green houses was falling apart so wasn't staying warm.
But I have noticed that the odd leaf as started to fall over, looking like it has been eaten away half way down the stalk for that leaf. It was on just one plant but now spread to 2. I presume this is some sort of aphid type pest. Before it gets worse is there anything I can do to stop any of my other plants being eaten before I can get them into the ground.
