Update and Caterpillar Nightmare!

Another obligatory cloud shot. On this one I was having fun with negative space, and I like the effect.

My garden as of August 10th. The weed pressure has been very minor since I planted so late and the weather's been dry. Even in a large-ish garden I don't have to do much control. The landlord has since mown the surrounding weeds down.

It's been ages since I last updated and things in the garden have changed. We had several weeks of dry weather and then some soaking rainstorms, which seem to have jolted the garden out of its dry slumber. My tomatoes are thriving, my beans are finally getting ready to flower, my peppers are flowering, and my turnips have shot up like crazy. Since most people around here are already harvesting the above vegetables, we'll just have to see if these catch up.


My 'Garnet Giant' mustard greens are doing well. They're tasty, but zingy enough to need cooking. I love the color.

My first acorn squash. I got this on impulse at the garden store and put it in a neglected corner of the garden, but it seems to be doing well after a couple weeks of droopiness.

Does anything smell as good as a tomato plant? Oh I hope these make it to maturity!

This shot would have been cooler if I had a manual focus. In the foreground is a cucumber I bought as a seedling, and in the background are seeds I planted. In the few days since I've taken this photo, they've developed at least 2 true leaves.

When I planted this garden I tried to remain detached, since it's my first time with a real, full-size garden, and I had no idea if I'd succeed. I couldn't help but get emotionally invested, though, and now I'm terribly upset by the possible demise of my cabbages. This is worsened, of course, by my desire to make gallons and gallons of sauerkraut.

It turns out that the pretty white butterflies that were 'gracing' my garden are known as 'Introduced Cabbage Moths'. They ugly eggs at the base of the petioles of cole crops, which hatch into velvety green caterpillars. RAVENOUS green caterpillars. They go to town on the leaves, leaving shot holes and eventually destroying or at least greatly reducing yield.

They tend to be a problem later in the year because they've had months to reproduce. It probably doesn't help that the garden was surrounded by massive weeds that the landlord hadn't mowed, where the moths could have been chilling out and reproducing on cruciferae family weeds.

These were nifty until I realized they were massacring my cole crops :'-(


This head of savoy cabbage isn't too badly affected by the evil worms, but you can see some of their naughty nibbling.

So, even though I swore I wouldn't go to great lengths to save my garden from threats, I did anyway and bought up some insecticide at the hardware store. I wanted to start with tamer stuff so I got insecticidal soap and pyrethrin dust. My attempts at control were interrupted by a trip to the City and an all-day rainstorm, so the damage got worse.

I started by picking all the caterpillars I could find off of the leaves and throwing them in a bucket to drown. Then I started spraying both sides of the leaves with the insecticidal soap, but the squirt bottle was a piece of junk and would stop working every 3-4 pumps. This drove me nuts, but I got as far as I could before it got dark (about 2/3 of the plants). After a day and a half, when it stopped raining (this morning), I gave up on the insecticidal soap and switched to pyrethrin dust. It stuck fairly well to the leaves and was much easier to use than the soap--I focused it on the stem and petioles. By this time, the eggs had swollen ominously. It's supposed to kill insects on contact, so hopefully it killed any that hatched this morning. Unfortunately it poured rain today and washed the powder off a few hours later. Pyrethrins are quickly de-activated by sunlight, so perhaps I didn't loose that much activity anyway. In the future I will apply it in the evening when there's no rain predicted.

Who knows if my efforts to save my cabbages will succeed or not. I'll probably apply the pyrethrins again, and then consider that enough. There's always the colorfully rustic local farmer's market. There's only one stand that seems to grow vegetables professionally--the others are just people who planted extra and shelled out $5 to put up a stand at the market. Oh yeah, and the old lady who sells the junk out of her house and uses the market as an opportunity to chat with everyone in town. She specializes dogeared dime-store romance novels :-P


The collards don't seem to like the heat, so I may need to seed a third time, or just give up on them. You can see an evil moth on the left, just waiting to wreak more havoc.



The 'Carson Yellow Wax' beans haven't sprouted at all, much to my disappointment. I'm not sure if it's a bad batch of seed, the heat, or if the resident critters just like to eat the seeds right out of the soil.

Other than the cabbages, things are going pretty well. There are some plants that don't like the heat, so I may do yet another planting. They're doing a little better with the mass of cool air that's hanging over MN, courtesy of Hudson Bay. Let's hope it persists (as it's predicted to)...despite the cold, wet spring the crops seem to be happy this summer and MN is expecting a record harvest (though of course that's due to a record corn PLANTING, thanks to crazy high prices).

Re-seeding and General Update

First true leaves on my daikon seedlings.

A happy garden hastily photographed due to mosquito attack.

My garden is coming along nicely, and the tomatoes and herbs especially seem to be thriving. Some seeds didn't do so well and I got low germination, so yesterday I re-seeded. The problem was worst among my green beans, where I got less than 50% germination and zero germination of the Carson Yellow Wax variety. I suspect that the seeds were predated in whole or in part and then rotted beneath the soil. My reasoning is that when I dug in the rows I found few seeds, and those that I found seemed to have holes in them and were rotted. (Though the rotting itself could have caused the holes, so who knows).

July 29th:
Re-seeded
  • Toscano Kale
  • Champion Collards
  • Hakurei Turnips
  • Scarlet Queen Turnip
  • Amour Pickling Cucumber
  • All varieties of green bean
Next I need to pop in a couple of more cabbage plants. I had one more red cabbage plant die on me--for whatever reason they didn't take to the transplanting. My sorrel hasn't germinated, or if it has I can't identify it. I will wait a while longer and then decide if I want to re-plant or maybe put in some Thai basil.

A red sorrel seedling from the Ohio State Website. My sorrel isn't red, but the seedlings should look something like that.

Beyond some low germination, things seem to be going well. I'm getting some leaf predation by flea beetles on my turnips and radishes (though fortunately as that's increased the nibbling on my cabbages has decreased). I might look into getting some floating row cover, but I haven't been able to find it at the couple of stores I checked at. I don't know how much aerial holes will prevent root development--I'm most interested in the roots and if nibbled leaves is the cost of keeping my cabbage un-eaten, I'll happily sacrifice my turnip greens.

My peppers are still playing head-games with me, but haven't died or anything, so that's good. Many of my tomatoes plants have unripe fruit now, byt I've learned not to 'count one's chickens before they hatch' when it comes to tomatoes, so I'm cautiously excited.

Amazingly, I have one pickling cuke! It matured so quickly because I bought it as a large greenhouse seedling. What do I do with one pickling cuke?

Weather-wise it's been a pretty typical few weeks of summer. Hot days in the low- to mid-eighties with rain or a thundershower every 3-4 days. I pulled back on watering a bit, but I'll go back to it to keep the new seedbeds moist. We're going to have some extremely hot weather this weekend, so hopefully it won't damage anything.

Weed-wise, the redroot pigweed is finally starting to pop up significantly. The seedlings are still quite small, though, so they're easy to control. It's the dominant weed, joined also by lambsquarters, purslane, and cheese-weed, and a few grass species in the mulched areas. I think the mulch brought in the grass seed--I should make more of an effort to identify it, but I usually pull it out before it's big enough to do so conclusively.
