Type: Hybrid (F1)
Class: Zucchini
Relative Days: 55
Shape: Cylindrical
Color: Dark Green
Life Cycle: Annual
Characteristics:
Tribute F1 is a hybrid zucchini maturing in about 55 days, producing an abundance of straight, cylindrical fruit with an attractive dark green color accented by light flecks. The plant has a medium, upright habit with an open vine structure, making harvest easier and more efficient. Known for its high yield potential, Tribute consistently delivers uniform fruit of marketable quality throughout the season. This variety is also disease resistant, adding extra reliability for growers.
Summer Squash (Cucurbita pepo)
Summer squash are harvested immature with soft skin and short shelf life. They are grown in both spring and fall in some climates. Varieties include:
- Straightneck: Yellow, bottle-shaped, straight neck.
- Crookneck: Yellow, bottle-shaped, curved neck, more difficult to harvest.
- Scallop: Flattened and ridged; white, green, or striped.
- Zucchini & Cocozelle: Green and yellow types; zucchini is the most common.
Commercial production favors straightneck and zucchini due to easier handling.
Temperature
Squash is a warm-season crop. Plant after frost. Germination is best at 85°F and poor below 60°F. For earlier harvests, use plastic mulch, row covers, proper orientation, or transplanting.
Soil
Best in sandy loam with high organic matter and pH 6.0–6.5. Use lighter soils for early crops. Avoid poorly drained fields. Rotate with non-cucurbit crops every 3 years to avoid soil-borne disease buildup.
Planting
Sow seeds 1–1.5" deep in rows 36–48" apart. Thin to 18–28" spacing. Use 3 lbs/acre (dribble) or 1 lb/acre (precision seeder). For plastic mulch, double rows spaced 18" apart are common. Plant every 10–14 days for a longer season, up to 60–70 days before frost.
Spacing
12–36" in row, 48–72" between rows
Harvest
Harvest when fruits are glossy and tender. Frequency depends on conditions—every 1–2 days is common. Leave a short stem on fruit. Use gloves to avoid skin damage. Quality declines as skin dulls. Harvest a planting for 2–3 weeks then move to the next.
Harvest standards by type:
- Crookneck & Straightneck: 1¼–2" diameter
- Zucchini: 6–8" long
- Scallop: 3–4" diameter
- Patty pan / Round: 2–3" diameter
Malformed first fruit is common due to poor pollination but resolves with more male flowers. Harvest consistently 2–3 times per week for best results.
Harvesting Blossoms: Harvest in mid to late morning when fully open. Cut 1–2" below flower base. Harvest only male flowers if fruit is desired from same planting.
