Hop Trellis Planner

Design a small-to-medium hop yard. Trellis height, row spacing, materials BOM, plant count, expected yield. Backyard scale through small-commercial.

Plan your hop yard

Yard dimensions

Trellis style Commercial 18 ft (standard) Commercial 20 ft (high yield) Reduced 12 ft (small farm) Backyard 8 ft Low-trellis 8 ft (commercial dwarf)

Number of rows

Row length (ft)

Spacing between rows (ft) Tractor-passable: 14 ft. Hand: 8-10 ft.

Plants

Plant spacing in row (ft) 3-4 ft typical; 5 ft for vigorous cultivars

Strings per plant 2 strings (training to 4 bines) 3 strings (6 bines, vigorous cultivars)

Primary cultivar (yield estimate) Cascade — 1.5 lb/plant dry Centennial — 1.8 lb/plant dry Chinook — 2.0 lb/plant dry Citra — 1.2 lb/plant dry Columbus / CTZ — 2.3 lb/plant dry Mosaic — 1.0 lb/plant dry Willamette — 1.6 lb/plant dry Nugget — 2.0 lb/plant dry East Kent Goldings — 1.4 lb/plant dry Hallertau — 1.4 lb/plant dry

Trellis style comparison

Style	Height	Use case	Cones / acre
Commercial 18 ft	18 ft	US standard commercial	800-1500 lb dry
Commercial 20 ft	20 ft	Pacific NW high-yield	1500-2200 lb dry
Reduced 12 ft	12 ft	Small farm; easier harvest	400-700 lb dry
Backyard 8 ft	8 ft	Home brewing	~50-100 lb at scale
Low-trellis 8 ft (dwarf cultivars)	8 ft	Mechanical harvest; specialty cultivars (Summit, Comet)	600-900 lb dry

Building the trellis

Standard 18-ft commercial hop yard structure:

• Posts: 25-foot pressure-treated poles (Class 4 / Class 5 utility poles), set 5-6 ft deep. End posts with deadman anchors. Line posts every 30-45 ft within rows.
• Top wire: 12.5-gauge high-tensile galvanized wire across the top, anchored to end posts.
• String / coir: Coir twine or sisal, dropped from top wire to ground for each bine. Replaced annually.
• End-anchors: Deadman blocks (precast concrete or wood), or screw anchors, set 8-10 ft into the ground at angles opposing the wire pull.
• Spacing: Rows 14 ft apart (tractor) or 10-12 ft (hand). Plants 3-4 ft within rows. Plants per acre at 14×3.5 ft spacing: ~890 plants.

Year-by-year yield expectations

Year	What happens	Yield (% of mature)
Year 1	Establishing crowns; minimal aboveground growth; do not train aggressively	0-25% (often pinched off)
Year 2	First real harvest; partial vigor	50-75%
Year 3+	Full vigor; sustainable production	100% of cultivar potential
Year 10-15	Crown decline begins; consider replanting	Decreasing

Critical management notes

• Hops are heavy feeders. N applications: ~150-200 lb/acre annually, split between bud-break and pre-bloom.
• Disease pressure is high. Downy mildew is the main threat — fungicide rotation needed for most cultivars in humid regions.
• Hops are dioecious — only female plants produce cones. Buy named female cultivars, never volunteer seedlings.
• Crowning / training is annual. Cut early-emerging shoots in spring (these are weaker), train second-flush bines clockwise around strings (their natural rotation).
• Wind exposure matters. Hops in heavy wind tear off the trellis. Site selection and trellis stability are critical.
• Hop yards last 10-20 years per planting. Cultivar replacement requires complete removal — crowns persist for years.
