The real advantage of gardening in San Francisco is that planting season rules are a lot like the pirate code.
Guidelines.
Guidelines that I cheerfully ignore. Sure I might get a failure or two (or three or four) but due to the weird late fall hot weather I might get some wild successes.
There are a few tricks with corn, and I know them from my parent’s wild corn successes when I was a kid.
One- corn is wind pollinated. This means that corn needs to be fairly densely planted so that it can pollinate it’s neighbors when it’s windy out.
Two- once the corn has been pollinated, it needs to be as warm as possible for the ears of corn to grow to full size and ripen fully.
The invisible point three is that they need a fair amount of water. The reason my parents stopped growing corn was that when I was around 8 we went into a drought. But our winter this year was so abysmally wet we were still having rain earlier *THIS MONTH* so I think I can get away with corn this year.
I think the late planting might actually work heavily in my favor as to point two.
Traditionally in San Francisco our hottest month was around August or September. Used to be it was a week or two we’d call “Indian Summer”. We’d have a mild early summer, and a hot late summer/early fall.
Then the last few years have gotten hotter and hotter. And last year we had sustained heat with only a few foggy days from mid-August to goddamn early November.
So yeah, climate change is real, and San Francisco’s weather patterns have definitely been altered.
That’s… really not a good sign for the overall health of the planet- but I’m growing vegetables in the climate I have not the climate I wish I had.
I can take advantage of this. I’ve already rolled the dice on late season tomatoes-now it’s corns turn.
Gardening is gambling.
If the last two years are any indicator my corn will be ripening this year at the best time.
As for it getting pollinated- I clustered one type of corn in a clump and the other type of corn in a right angle around the edge of the bed. The wind will do the rest, and as my garden is so windy I have to put all my herbs in ceramic pots so they don’t fall over- I think Mother Nature has that one covered.
Pictured, my rapidly growing apple mint, transplanted from a cruddy plastic pot that I had to wedge in between other pots to prevent a spill, into a proper ceramic pot that laughs in the face of wind.
In other less technically fraught planting news, I transplanted my green onion starts into their new home. This is a former pepper pot that now houses the dirt I saved from the potato bag I harvested. Got to save your good dirt! I figured since I seem to be all in on tomatoes this year and not into peppers, I might as well put the scallions here. I’ll probably seed another few six-packs tomorrow so I can just have perpetual green onions. One of the best things about San Francisco weather is that things like scallions can basically be grown year round.
Another vegetable that has an elongated growing season is any squash. These little beauties are spaghetti squash- which oddly I’ve never grown before. I’ve been growing them from seed, and now they’re going in opposite the pumpkin. As long as it isn’t raining you can grow squash here- they don’t like their leaves getting wet.
And lastly I potted one of my Roman mints. This was taken as a cutting from the dying thunderdome, and lovingly grown in a series of plastic pots. It has now graduated to a ceramic pot of its own. This means the mint thunderdome no longer serves a purpose and I can compost the twigs and re-purpose the pot. The mint thunderdome was an interesting experiment, but the roots of the mint plants are basically suffocating each other and its time has come.
Speaking of pirates- I have some new feline invaders. This is a lovely tuxedo cat that comes around from time to time, and is apparently female, not a tom as previously assumed, as she’s toting around two fat little kittens that were too fast to photograph from my window. I nearly tripped over them today while watering, and they cartoonishly flung themselves over the fence to get away from me.
Kitten season. Oh joy. If I can impart any lesson to my readers it’s this. Please spay and neuter your outdoor cats!
I’d rather not spend my time outdoors sneezing my head off.
The Neanderthal Gardens 
That looks exactly like that cat that’s been loitering around my garden!
Your garden is looking great (and making me hungry)! I have a shady lot that gets enough sun to squeeze out some short season plants, but I’ve learned (after many stubborn attempt) that the angle of the sun just isn’t right for anything like squash or melons.
I do not grow corn because of the space and water it wants, and because it is so cheap in the store. The last time I grew it was for a naughty reason. My neighbors were complaining that I was doing my own landscape maintenance, and they could see from the sidewalk that vegetable plants hanging over the fence. (Vegetable plants, like hanging laundry, were to be kept out of view in the backyard.) Anyway, I planted corn right along the driveway as ‘ornamental grass’. It was gratifying, and surprisingly productive. It was some sort of grain corn that I put out in a single row. It really was just there for aesthetics, as I did not expect a single row to pollinate itself. Nonetheless, it made good fat ears of grain corn that I did not know what to do with. If I had known it could pollinate itself, I would have grown something useful, like sweet corn or pop corn; but of course, if I had, it probably would not have been so successful. All we could do with the grain corn was bash it up and make polenta with it. It was not very good, like raspy grits with tomato sauce.
