Jeff, I don't usually divide chamomile since it reseeds so easily. I will cut it back really, really hard once it is about through with a flush of flowering and it will then regrow and reflower. The method used to propagate chamomile depends oh which type you are growing. If it is English Chamomile, you can propagate it via seeds, division or by layering. If it is German Chamomile, you usually propagate it by seed only. I treat dill the same way as chamomile, cutting it back hard if I want to keep it growing and in flower, or let it go to seed if I want the seeds for cooking. I have never heard of anyone propagating it via division or cuttings, only by seed. Sage is easy to grow from cuttings. I have never tried to divide it from the rootball and don't know if that is how it is usually done. But, if you see clumps forming away from the main clump you can dig the little clumps up, separate them from the mother clump and replant them. Cut back the topgrowth of the divisions a little to compensate for the shock of being dug and transplanted. You can divide many perennial plants by cutting the rootball in half, but you will always have to cut back the top a lot to compensate for the digging/cutting/replanting. I usually just let the herbs grow into huge monsters. I tend to let them reseed, and then I just dig up the tiny seedlings and put them where I want them. In a rainy year, I will cut back herbs many, many times. Dawn

Is there any way that you can kidnap a couple of those caterpillars and take a good close-up picture for identification? Put them in a glass and stick it in the freezer for a little while to slow them down, if need be. Since I can't tell from the image you've given us what species this is, I suggest that you wear gloves when handling...there are some nasty stinging caterpillars out there. (Am thinking in particular of the Buck Moth caterpillar!) If I've successfully scared you from handling it, perhaps you can describe it. I will tell you that it is in all likelihood a moth of some sort. Butterfly caterpillars don't lay their eggs in large masses like that. What kind of tree is that over the garage? That would be a good clue.

Susan, I started doing square foot gardening in the mid-1990s and it works really well for some things and not as well for others that get really large in our climate. My spacing that I use now is sort of a hybrid of spacing from Square Foot Gardening and from John Jeavons' "How to Grow More Vegetables....." book, which has a complete title about as long as the distance between Marietta and OKC. I've just experimented with the spacing until I find out which one gives me the best yields. I think Square Foot Gardening would be great for you, but encourage you to think of it as Cubed Foot Gardening and grow as many plants upright on trellises, cages or arbors as you can and you'll get even higher yields per square foot. With smaller plants like lettuce, onions, carrots, etc., the standard Square Foot Gardening spacing works fine. With larger plants that turn into monsters in our climate, like Indeterminate tomatoes, squash, etc., I go more with John Jeavons' spacing or space my plants even further apart. With peppers, it generally varies, depending on whether a given variety gets 2' tall or 4' tall or taller. I have found most peppers give a really high yield even with close spacing, and so do many determinate tomatoes. I see Lunas most years in April, but not every single year. I usually don't see them in a bad fire year, but I'm not sure if that's because they aren't "here" or if I am just gone so much during a bad fire season that I miss seeing them when they are here. At our house, I almost always see them either on the ground in the area under the big security light that lights up the garage/parking area or hanging around outside the plant shelf window. When I see them at the fire station, it usually is early in the day and they're normally lying on the ground near the security light that illuminates the front of the station. I've never seen the larvae, but we have acres and acres of woods so they could be anywhere. We have tons of native pecans and hickories scattered all over our property (and on the surrounding acreage as well) so I guess that explains why we see them pretty regularly here. When I was a kid, they'd hang out on the front porch, usually on the screen door, when we were playing in the yard in the evening. It seems like we saw them a lot more often back then than we see them now. We have every kind of wildlife you can imagine here (as you well know) and most of it is a pleasure to have around. Seeing the lunas, because of their relative rarity, is a real thrill. Dawn

Thank you @gardengal48 and @rhizo_1 for the suggestions. I'm off to go track some down right now. I was hoping a mixture of dish soap and/or chili peppers (something along those lines) might work so I don't have to go purchase. Once you start gardening, then the "supplies" start to really accrue over time! ;)
