Benefin is used in commercial lettuce fields to give the direct-seeded lettuce a head start against the weeds. I guess I've eaten lettuce grown in those fields since I don't always buy organic lettuce.

Oryzalin has been widely used in orchards and fields, from almonds to walnuts
Again, we've all probably eaten fruit, vegetables, and/or nuts grown in soil treated with this.
Would I eat the vegetables in your garden? Not knowingly - and after doing an internet search on these 2 chemicals I'm going to think more carefully about what I buy in the grocery store, even if it's not on the "Dirty Dozen" list. It's your choice whether you want to - I'd contact the manufacturer and tell them how much you put down, when, and what crops you're growing. Since they labeled it for ornamentals and not veggies, the lawyers will probably tell you it's not advised.

I don't grow it intentionally (there's no need!) but I do take advantage of what grows naturally. I did find the information below on a Google search, on one of the weed management sites from Purdue university. Granted the information was intended to suppress the plant, not to encourage it - we can use knowledge any way we want to, right? :-) I linked the source, too, if you want to look.
"Brown seeds germinate readily, while black seeds are more dormant. Many of the seeds remain on the plant until early winter and these small, smooth seeds have no other apparent adaptation for dispersal other than their high density and ability to spread from site to site by various means, including equipment transfer. The seeds also can survive well in the digestive tracts of cows, sheep, and horses, so manure is considered a possible source for introducing seed.
Seed dormancy in common lambsquarters contributes to
its success as a weed. Under certain conditions it can
remain viable in the soil for several decades. In fact, viable
seeds have been recovered from medieval ruins in Europe
(Mohler and DiTommaso). Most seeds require some
time before they are ready to germinate. Light, strong
day and night temperature fluctuations, and the presence
of nitrate in the soil increase common lambsquarters seed germination (Mohler and DiTommaso, 2006).
Some research suggests that only 10 to 30% of the current seasonâÂÂs seed will germinate under favorable conditions the following season (Forcella et al., 1997)."
When growing quinoa, a close lambsquarter relative, it's recommended to refrigerate the seeds before planting if nighttime temps are much over 60. I wonder if something similar might be helpful for lambsquarters, especially if as the source cites, strong day and night temperature fluctuations are useful?

Wow, thank you, Lily!
Sounds like if I want to grow in flats (which I do), I should put the trays in the fridge at night and somewhere warm during the day.
I had no idea about the brown and black seeds! I had noticed the different colors, but I thought the brown ones were immature. I mostly planted the black ones O_o.
Does anyone grow them for the seed, for eating? I saw something in my previous web searches about the seeds being found in the stomachs of neolithic folks in england. Seems like you would need a lot of plants for one bowl of food, but that's true for any grain/seed crop.
I did include semi-mature seedheads in my last dish of greens. Crunchy and tasty.


Thank you for including your summer high temperatures.
It does seem a difficult time to grow cauliflower. Could you put them in a shady place for a while where it will be a bit cooler? You could then put them in the ground next month. The main problem would be that they would bolt before forming nice heads. Since they were free, there's no harm in trying. You could plant a few now and a few next month.

Thanks seysonn! That may be it! I just checked out some pics of immature peppercorn flowers and foliage and it looks similar.
Strange that it got mixed in with the capsicum annum seed pack. And stranger that I didn't notice I was planting A PEPPERCORN. Maybe it fell in the germinating cup or something and I just didn't notice.
Is peppercorn even worth growing (especially in an Earth Box)?


I zoomed in on the bottom and it might be an optical illusion, but I see a hole with two borers.
That said, it may just be an illusion since it's not clear. Especially since I have SVBs on the brain after the one got flushed out of the bore hole the other day while I injected BT.

I've had my RQ tassel at the heights you indicate and continue to grow upwards while forming the ears. I'm curious, nc-crn, do you mean the red coloring or the odd kernel placement(which also happened on my RQ)? Anyway, I'm not wedded to the idea that it's just mislabeling, it was just very striking how much like RQ those plants look.


I'm not very familiar about the planting time for garlic. If you have standing water in wintertime, I suggest that you make some raised strips with walk and drainage channels between the raised strips through the field. The raised strips could be augmented with some organic matter. The dirt for raised strips simply comes from the channels.
Daikon radishes [tillage type] is my favorite cover crop and it winter kills here, but probably not out where you are, so you might have to mow and till it in spring.


Not an expert but heres my expereience:
Some carrot varieties keep better than others. I grew nutri red carrots this year and last and find that they dont keep well. They go soft quickly (im talking just a couple of hours) and look a bit like yours in the photo. The orange ones kept much better. And yes, if you cut off the tops and store them in a cool place, they will keep much better.







This thread is leaning towards urban gardening but I have seen threads with people complaining about contamination in rural lands. Pesticide/Fungicide/Herbicide and fertiliser were used much more liberally post WWII. A lot of those chemicals are no longer allowed but still reside in soil currently farmed on.
If you have access to virgin soil, untouched by human activities you are very lucky. An urban plot may have better quality soil than an old farmstead, and vice versa of course.
should present no problem, as most of that fall out is probably not in a soluble form, if you use raised beds all the better. we are growing a tree barrier between us and unsealed road 70 meters away, this should block a lot of dust that will contain residuals from vehicles.
