Sounds like a good bet--might even try one square of them at 6-inch spacing, since your soil is far richer than the average bed, and you can plant shallow leaf lettuces around the brocs.

With occasional use of thermal row cover, you should be able to garden year 'round in the Carolinas. Year before last, my peppers survived 3-day freezes uncovered--only the top layer of leaves died back at each freeze. I had red peppers on plants on January 1. The tomatoes (trellised on wire fencing) lost their leaves, but the green stems and roots continued to grow out the "marbles" I had left on the branches, and even set a few new fruits during warm spells. I had fresh maters in early December. And those were mainly just Celebrities, IIRC.

All the best for a fabulous Fall!

I planted broccoli, not 100% sure, but I think it's munchkin. Anyway, I planted them 1 per square foot. My excellent soil supports this and in fact my broccoli are growing extremely well. Almost too well. I have carrots, onions and other things next to my broccoli and the broccoli leaves are so huge they are shading the other plants and making it hard for them to grow. So I've been pinching off some of the larger leaves.

I think they need more than 1 square foot, maybe 16 inches x 16 inches. Next time I think I'll not fully plant the neighboring squares.

Howdy, Monika.

Sounds like your brocs are just fine--squarefooting is all about crowding. We crowd out weeds, crowd in more nutrients, and crowd more productivity out of our gardens.

You might just plant the brocs along bed edges or beside something big enough to fend for its own square. lol

Yes, my garden does seem a bit crowded, it's good to know that's what it's supposed to be like, this is my first year with a garden.

Not only are my broccoli space-hogs, but my beans are going crazy and shading out my onions and garlic. Maybe a little more planning next year to help contain everything in it's respective square. ;)

Broc's are doing fine in Boris' Box...

I always plant my broccoli no further than 1 foot apart in all directions & always get a bumper crop - even in hot weather. And that's with standard varieties.

I plant in deep well-composted free-form raised beds, & believe that the close-spacing keeps the soil cooler via the dense leaf cover. I've even managed to grow some lettuce under & around the broccoli plants that I'm able to harvest before the broccoli is ready.
