History
Catskill Brussels Sprouts is one of the most celebrated heirloom Brussels sprouts varieties in American gardening history — a compact, productive, and deeply flavorful strain that has been a staple of home gardens since its introduction in the 1940s. Named after the Catskill Mountains of New York, this variety was developed specifically for American growing conditions, producing shorter, more manageable plants than the tall European strains that preceded it while delivering larger, more uniform sprouts with exceptional flavor. Catskill quickly became the go-to Brussels sprouts variety for home gardeners across the country, prized for its reliability, compact habit, and the rich, nutty flavor of its tightly packed sprouts. Open-pollinated and non-GMO, Catskill remains the benchmark heirloom Brussels sprouts variety for good reason.

Flavor Profile
Catskill Brussels Sprouts deliver the rich, nutty, slightly sweet flavor that Brussels sprouts lovers crave — bold and savory with a pleasant bitterness that mellows beautifully with roasting or a touch of frost. The sprouts are dense and tightly packed with a satisfying, meaty texture that holds up to high-heat cooking. After a light frost, the flavor sweetens noticeably as the plant converts starches to sugars — one of the great rewards of fall gardening. These are the Brussels sprouts that change minds about Brussels sprouts.
Growth Type & Harvest Yields
Catskill is a vigorous, upright cool-season crop that produces abundant sprouts along a central stalk over a long harvest window. Its compact 24–30 inch height makes it more manageable in raised beds than taller varieties. Sprouts develop from the bottom of the stalk upward — harvest lower sprouts first as they mature, allowing upper sprouts to continue developing. A single plant can yield 50–100 sprouts over the course of the season, making Catskill one of the most productive heirloom Brussels sprouts available.
Disease Resistance
- Good tolerance to clubroot and black rot — improved over older European strains
- Performs best in cool, moist conditions — heat causes loose, bitter sprouts
- Susceptible to cabbage worms and aphids — monitor regularly and use row covers if needed
- Tip: Rotate brassica crops annually and maintain soil pH above 6.5 to reduce clubroot pressure
Growing Tips & Planting Dimensions
- Spacing: 18–24 inches between plants, rows 24–30 inches apart
- Sow depth: ¼–½ inch deep indoors; transplant when seedlings are 4–6 weeks old
- Germination: 7–10 days at soil temps of 65–75°F
- Full sun — at least 6 hours of direct sunlight daily
- Prefers rich, firm, well-drained soil — loose soil leads to loose, open sprouts
- Stake plants in windy locations — tall stalks can topple under the weight of a full crop
- Remove yellowing lower leaves as the season progresses to improve air circulation and sprout development
When to Plant
Start indoors 6–8 weeks before your last frost date for a fall crop — Brussels sprouts are best grown as a fall crop, maturing in cool weather and after light frosts for peak flavor. Transplant outdoors in midsummer so plants mature as temperatures cool in fall. In mild climates, can also be grown as a spring crop — start indoors in late winter and transplant early. Brussels sprouts do not direct sow well outdoors. Find your frost dates and hardiness zone at the USDA Plant Hardiness Zone Map.
