2. Komatsuna: Japanese mustard greens

Carlton F1 Komatsuna:

Carlton F1 Komatsuna is resistant to bolting. I tested an heirloom variety before this one and it bolted within two weeks. With Carlton F1, I was able to enjoy multiple harvests that stretches out more than a month long. So I just need to sow seeds once a month versus every two weeks to maintain a consistent supply from September to March. Seeds purchased from Johnny’s Selected Seeds Company. I do offer $1 seed packet for this variety for those who are interested in splitting up the seed cost with me. Please refer to my Seeds For Sale Inventory on how to place a seed order in the Shop tab.

Notes: Carlton F1 Komatsuna seedling batch sown on 9/15/26 germinated on day 2.

General Information About Mustard Greens:

Here in Oviedo, Florida zone 10A, I grow mustard greens from September through March. I grow my mustard greens in Vego Garden 17-inch high raised bed. I also tested growing them directly in the ground. The plants growing in the ground tend to have some pest issues when weather is warm but grows fine when the weather cools down in the 70s and lower. Mustard greens are resistant to Root-Knot-Nematodes and grows well in pots, raised, beds, and in the ground for me. Mustard greens have a shallow root system so growing them in a 12-inch raised beds will work just fine too. All mustard greens have a spicy taste but how spicy each plant is depends on variety. So far, I think the Red Giant Mustard had the spiciest taste that reminds me of Japanese wasabi. Mustard greens are high in Vitamin E and folate compared to kale. Mustard greens if not grown for consumption are grown to serve as green manure where farmers grow mustard greens as a cover crop, chop it up and till it into the soil to enrich it.
