I notice this bug on my Brussel sprouts this morning. Help?? I also noticed some yellow bottom leaves on most plants. Is this normal?

Yellowing bottom leaves can be normal aging or it can be nitrogen deficiency. Are you seeing this on most brussels sprouts plants, or most plants in general? The bug resembles a Colorado potato beetle larva but the dots don't seem to be in the right places for that. Can you get any other shots of it, more from the side for example? Does it appear to be eating the Brussels sprout leaves?

I am seeing this yellowing and some purple on all the brussels sprouts plants and adding some pictures. I have seen the bug a few times, not just on the Brussels sprouts. When I see it again I will get more views. Thanks!

I wouldn't worry too much about the lower leaves yellowing as long as it is only the lower ones - but have you given them some nitrogen?

The organic nitrogen in cut grass would have to be broken down by microorganisms before it will release usable nitrogen to the plants, so you might want to think about some purchased fertilizer in the short term. If you're trying to grow them organically rather than using "chemical" fertilizers, then this article may be of interest:

Great link, Sue! I saved that PDF. Pure organic farming is even harder than I thought!

P.S. I think that many plants suck the N out of their lower leaves when they are growing faster than their roots can take up more N.

It might mean infertile soil (add soluble N). (Maybe reduce leaching by adding compost or even some clay to very sandy or gravelly soil.)

It might mean that the top of the plant is just plain growing faster than the roots can keep up with (just wait for it to get back in balance? Next year amend the soil to be more hospitable to roots?)

It might mean some other trouble with roots, like being eaten by something, or drowning and rotting after the soil flooded and ran out of oxygen (improve the drainage and/or water less heavily).

It's also getting really late and really warm for Brussels sprouts to be growing in Georgia. They're cool-weather veggies so you definitely need to give them some sort of soluble fertilizer that they can use right away if you hope to get a crop before the heat ruins the sprouts. How about fish emulsion?

Btw, I grow Brussels sprouts and other cabbage-y things in the winter here, although I'm a lot further south than you. I plant them around the beginning of October but you could probably plant in late August or any time in September. You'll get tastier, tender sprouts if you can get them maturing in cool weather.

Cheryl and Jolana, good suggestion, I was assuming it was moving! It doesn't look like a ladybug larva, but does look like a pupa.

This is the larva:

Rick, yes I think it depends where you're gardening. I had no problem gardening more or less organically at our old home which was on clay (I amended it with composted manure from the barn). I thought organic gardening was a piece of cake until I moved to a drier area with sandy soil, and every veggie pest known to mankind (or so it seemed :lol:) descended upon the plants. In hindsight this might also have been partly because before we were surrounded by continuous corn.......

Thank you everyone! After 3 crops I have yet to get little brussels sprouts. I don't go down easily tho...so I'll keep trying. Thrilled to know there are lady bugs being born here! Hurray!

I tried to use big gardening words again. Should have known better.I should have just said "baby ladybug".

Hmm! Maybe even plant pests appreciate variety in their diet.
