Aspabroc broccoli matures in just 56 days from transplant, delivering tight, dense heads packed with vitamins C, K, and B-complex minerals. What makes this variety remarkable is broccoli's calcium bioavailability: your body actually absorbs the mineral more effectively from broccoli than from milk, making every harvest a genuine nutritional powerhouse. Grown in full sun with consistent moisture and well-draining soil between pH 6.0 and 7.0, this upright cultivar rewards quick harvests with a secondary benefit: cutting the main head encourages vigorous side-shoot production for continued picking throughout the season.

At 56 days to maturity, Aspabroc delivers speed without sacrificing the dense, tight heads that signal peak harvest time. The real advantage lies in its side-shoot productivity: once you cut the main crown, the plant keeps producing smaller florets for weeks, extending your harvest window far beyond a single cutting. For gardeners seeking efficiency in a compact footprint, spacing just 4 inches apart with 18-inch row spacing, Aspabroc lets you grow abundance in tight quarters.
Aspabroc is grown as a fresh vegetable crop, valued for both its main head and the secondary side-shoots that continue producing after the primary harvest. The dense heads are best harvested at peak firmness and immediately prepared fresh, though proper storage extends usability. The abundance of side-shoots makes this variety particularly suited to gardeners seeking multiple harvests from a single plant rather than a one-time cutting.
No timeline data available yet for this variety.
Start seeds indoors 4 to 6 weeks before your last spring frost to time transplants for the optimal window. Keep soil temperature between 65 and 75°F for consistent germination.
Transplant hardened-off seedlings into the garden after the last frost date, when soil has warmed and daytime temperatures consistently exceed 50°F. Space plants 4 inches apart with 18 inches between rows.
Direct seed outdoors beginning in April in suitable climates. Direct-seeded Aspabroc requires 81 to 91 days total to maturity (the 56-day count applies to transplants only). Sow seeds 1/4 inch deep in prepared soil.
Harvest the main head when it reaches tight, dense firmness and before yellow petals emerge, as flowering signals the onset of decline. Remove the entire head plus at least 6 inches of stem using a sharp knife angled to prevent water pooling on the cut surface. Once the primary head is harvested, monitor side-shoots regularly and cut them as they reach harvestable size to encourage further production. Time your main harvest for 56 days after transplanting to catch peak quality.
No formal pruning is required for upright growth. Instead, harvest the main central head when tight and dense, before any yellow petals appear, by cutting at least 6 inches of stem with a clean, sharp knife angled to shed water away from the cut surface. Regular cutting of developing side-shoots encourages continued branching and extends your harvest window significantly.
