Last year I accidentally brought some aphids indoors. One plant in particular was in my office window before dying. Removed the plant but a couple months later started using the area with lights as my indoor greenhouse.

Now that office window has a table crammed with way too many plants.

I had a bunch of gnats surrounding that area, but I've had lots of problems with fruit flies elsewhere in the apartment. So I figured that was what it was. I tried vinegar traps, which worked wonders in the kitchen, but I don't appear to have the right kind of vinegar. I didn't get around to putting up the sticky traps, but it look like the problem mostly went away.

The radishes didn't seem to be doing much, and they were overshadowed by some lettuce. I took a look at them, and saw an aphid on the plant rim.

A closer look saw that there were tons of aphids all over the place. I dumped out those two pots. A quick look of the rest doesn't show anything, but there were way too many aphids to assume they were just on the two sickly radishes. I'll take a look later.

I'd been debating putting the most recent plantings of lettuce outside, and pulling out the oldest ones and redoing the pots with fresh soil.

That leaves me with 4 tomato transplants, and three lemongrass plants.

In another room, I've got my seedling incubator setup.

When the seedlings get bigger, I will need someplace to put them. I also need to keep the tomatoes and lemongrass going while waiting for the weather to get nice.

Should I move my whole setup to another part of the house? Even if I do, I'd like to move cool season plants back in here in the summer.

What can I do to:

a) clean up the particular location (corner of very messy office) so that I won't get aphids again?

b) clean off the tomatoes and lemongrass so I don't continue to have problems?

c) check the lettuce that is going outdoors to make sure that it isn't infesting the weak outdoor lettuce/pea/carrots/radish seedlings?

Also, I got nasturtium seeds because I heard it was a companion plant for tomatoes and such aphids. It turns out it *attracts* aphids away. So if I plant nasturtiums, should I place them at one side of the crowded planting? Only put them in if the planting is displaying signs of aphids?

Thanks,

Alice
