Aphids on newly arrived lemon tree

Question

I ordered some Meyer lemon and a Persian lime tree from 2 different growers. The lemon and lime tree (from the east coast grower) arrived in great condition. I acclimated them per the grower instructions and re potted them. They are doing great.

Then, after some weather delays the improved Meyer lemon I ordered arrived from the west coast. The plant had a long travel go but arrived only a smidge worse for the wear (parched, left on my doorstep for hours at freezing temperature). Pretty girl has blossoms though. While I was giving her a drink, I noticed that her leaves had holes and she had aphids. I thoroughly cleaned the leaves. Absolutely no directions from the grower as to acclimating and when to repot.

I will follow the directions of other grower. But since she arrived with aphids it would be best if I quarantine her to another part of the house away from my healthy lemon/lime even though I washed the leaves, correct? I put her upstairs. Same south western light but just not near the other healthy plants.

Answer 1

This is one of the mildest pests that will attack your citrus. They are the easiest to get rid of, but there will be times that you have much harder to control insects on them. You were correct in isolating them until the infestation is gone. Continue to wash them off or follow tips below.
