This is what we’re aiming for – healthy kale plants to feed us during the winter! I reported last week that we had got one bed of kale sown. It’s up nicely under the rowcover, so we can use some of those plants as transplants to get more beds established when we do manage to get more beds tilled and prepped. Yesterday we sowed more kale – three partial beds which had held our fall broccoli and cabbage transplants.
We have at last got our final row of cabbage planted out, so the nursery seed beds are fairly emptied out. Not entirely though. Our next transplanting job is to fill gaps in the rows. We have 8 rows of broccoli and 4 of cabbage, 265 ft long. A hundred people eat a lot of food! Meanwhile, we raked around the remaining broccoli and cabbage transplants, and sowed more kale. A bit chaotic, having beds with big old plants and freshly sown ones, but manageable. all are covered with spring steel hoops and ProtekNet insect exclusion netting made by Dubois Agrinovation., which I have raved about previously. It keeps Harlequin bugs and flea beetles out.
We like Vates as it’s the most cold-hardy kale we’ve found and we can leave it outdoors without protection in our zone 7 winter and harvest from it about once a week. One year we did try covering it with floating row cover, to boost production, but it was a sad mistake! The fibers of the polypro row-cover got snagged in the frilled crinkled leaves, which made the cooks very unhappy!
Last winter we grew some Beedy’s Camden kale from Fedco

It was faster growing than Vates, and the leaves are wavy rather than frilled, and some people liked a change from our usual. Rated as hardy to zone 5, it wasn’t as cold-hardy as Vates in our garden. We are growing some more this winter.
We had planned to try Blue Ridge kale from Osborne Seeds, but they had sold out by the time I tried to order. It has done well for Clif Slade at his 43560 Project at Virginia State University, where the climate is a little milder.

While shopping, I bought some Black Magic kale. We have tried these Lacinato kales in the past, both outdoors and in the hoophouse, without much success. We’ve had aphids building huge colonies in the curled back leaf edges. We’ve had indifferent growth. I’ve tasted great Lacinato kales at friends’ houses, outside our region. But every few years it come time to try a previous failure again, and we have some new crew members enthusiastic about this one, so we’re giving it our best!

Two weeks ago I asked if anyone knew if zipper spiders ate hornworms. I did some reading, and I think it’s possible they do. The Latin name for these spiders is Argiope aurantia. I found out that all the many, many zipper spiders I’ve been looking at are females. The males look quite nondescript. I also confirmed that the 3/4″ brownish sacs we had hanging all over the hoophouse all last winter were indeed egg sacs of the zipper spider. Each one held over a thousand eggs! Golly! This is better than science fiction! Wikipedia says prey can include not only insects, but also small vertebrates such as geckos, so it seems likely that hornworms could be on the menu. Does anyone have a good source of information? There’s a YouTube of a spider eating a hornworm. I haven’t got enough bandwidth to watch it. Let me know if it’s good.

The YouTube video is captioned “female garden spider eating a caterpillar we gave her.” Though it is fun to watch the spider going after the hornworm that a person had deposited in her web, I’m not yet convinced that hornworms would get themselves caught in a web often enough for these spiders to be a meaningful source of hornworm control. The webs seem more suited to catching fliers than walkers or crawlers.
I’m trying to envision how a reptile would get caught in the web & whether human intervention might be involved there, too. One way or another, it apparently can happen, though. Found this photo of a garden spider with a skink in its web: http://www.shutterbug.com/content/spider-eating-lizard
Keep us posted on whether you see hormworms getting themselves caught in webs.
Good point, Joanna. Recently, four zipper spider webs had big horseflies in them. I’m happy to have fewer of those brutes around! I tried feeding a hornworm by sticking it on the web. Haven’t checked the result yet. Do the spiders also go out hunting? Or do they just wait for fliers to get trapped?
I think most web-building spiders rely on their webs to catch prey (though nature always seems to have bizarre exceptions to any “rule”). The following description certainly implies that what garden/zipper spiders eat is directly related to what gets caught in the web: http://mdc.mo.gov/discover-nature/field-guide/black-and-yellow-garden-spider
Hooray for anything that eats horseflies! They’ve been bad here, too.
