Approximately 7-14 seeds per gram. Cucurbita pepo Lot# ZU42004 Round Zucchini is an impressive plant with speckled green leaves born on a vigorous bush-type plant. They are super-fast growing and are generally eaten when they are 7-10 cm (3-4”) in diameter. Fruits go from flower to fruit in about 7-8 days. Round Zucchini has a white to light green flesh that has a very mild flavour and they are perfect for any squash dish. It is a very heavy producer. Keep fruits picked for a continuous harvest until frost.
Direct sow the seeds in June once the soil is warm up to at least 21˚C (70˚F). Sow 4 to 5 seeds 12 mm- 2.5 cm (½-1”) deep into hills or rows. Space hills 91-121 cm (3-4’) apart. When the seedlings are 5-7 cm (2-3”) tall, thin them to 2-3 plants per hill. If planting rows, sow seeds 10 cm (4”) apart in 91-121 m (3-4’) apart. When the seedlings are 5-7 cm (2-3”) tall, thin to one plant every 45-61 cm (18-24”). For transplants, start indoors 3-4 weeks before transplanting outside. Sow 3 or 4 seeds per pot and thin to one or two plants. Harden off seedlings gradually by cutting back on water and expose them to sunlight daily. Seedling should have more than 2 to 3 true leaves prior to transplanting outside.
Soil Conditions: Well worked rich, loose well-drained soil. Ideal pH: 6.0-7.5
Planting Depth: Sow seeds 12 mm- 2.5 cm (½-1”) deep.
Germination: 3-10 days.
Height at Maturity:Round Zucchini plants reach 61-76 cm, (24-30”) tall. Spread is about is 91 cm (36") wide.
Days to Maturity: 42-65 days.
Watering: Zucchini plants require at least 4-5 cm (1½-2”) of water a week. This will ensure good growth, whether they are grown in single hills or wide rows. The amount of rain that falls during the week will help supplement how much you should water your garden. Soil should remain mildly moist. Do not water shallowly. The soil needs to be moist 4 inches down.
Sun/Shade: Full Sun
Spacing after Thinning: Space transplants one plant every 45-61 cm (18-24”) apart in rows 45-61 cm (18-24”) apart.
Additional Information You will not need to grow many of these plants as they are quite prolific producers unless you have lots of friends and family that enjoy zucchini. The bush habit is rather closed and can make harvesting a bit of a challenge. Sow zucchini in the garden as early as 2 weeks after the last average frost date in spring. To get a head start on the season sow zucchini indoors about 3 weeks before you transplant it into the garden. Sow successive crops every 2 to 4 weeks to extend the harvest and to protect against crop loss to insects or disease. Time all plantings so that squash comes to harvest before the first frost in fall.
