What it is

Broccoli (Brassica oleracea italica) is in the Brassicaceae (Mustard) family. Harvest the central head, then keep cutting side shoots for weeks. A cool-season heavy hitter.

How to grow it

It wants full sun, water it even, and give it rich soil. Target a soil pH around 6.0–7.0. Space plants about 18 in apart. Expect roughly 60–90. Cool-season.

How it's used

Broccoli is used: steamed, roasted, raw.

🔎 How to identify it

  • Blue-green leaves
  • Dense flower-bud head
  • Side shoots after main cut

The grow guide

How to grow & propagate broccoli

Everything I've worked out about starting this one, keeping it alive through a Texas year, and turning one plant into many — free.

How to propagate broccoli

The cabbage family is a cool-season seed crop. Start the heading types (cabbage, broccoli, cauliflower) in trays 5–6 weeks before you want them in the ground; sow the fast roots and greens (radish, turnip, mustard, arugula) straight into the bed. They all cross with each other readily, so if you're saving seed, only let one variety of a given species flower at a time.

Growing broccoli in Texas

Give it full sun and rich soil. Match the spot to the plant and most of the battle is already won.

This is a cool-season crop. On the Texas Gulf Coast that means your real windows are fall and late winter, not summer — sow as the heat breaks in September–October and again in late winter, and you'll harvest through our mild winters while the rest of the country is frozen out.

Keep moisture even, especially while it's young — deep, less-frequent soaks build better roots than a daily sprinkle.

Harvesting

Figure on roughly 60–90 before you're harvesting. Harvest at peak and keep harvesting — most vegetables produce harder the more you pick, and one left to over-mature tells the plant its job is done. The part you're after: heads, side shoots, leaves, stalk.

Making more for free

Every seed we sell is open-pollinated, which means you can save your own from the best plants and it'll grow true next year. Let a few of your strongest plants finish and go to seed, dry it fully, and store it cool and dark. That's the whole point of heirlooms — buy once, grow forever.

🌤 Before you plant: check the live 7-day garden weather to time it right for frost and heat.
