How to Sow

  • Sow seeds directly in the garden in fertile, warm soil in full sun after danger of frost has passed.
  • Be sure to choose an area when you did not plant squash or related crops within 2 years.
  • Sow 1-2 seeds about 36 inches apart. Cover with 1 inch of fine soil.
  • Firm lightly and keep evenly moist.
  • Seedlings emerge in 10-14 days.
  • Thin to one plant when seedlings have two sets of leaves.

How to Grow

  • Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their seeds from germinating. 
  • Squash plants have a shallow root system, mulches help retain soil moisture and maintain even soil temperatures.
  • Keep plants well-watered during the growing season, especially during dry spells. Plants need about 1-2 inches of rain per week during the growing season. Use a rain gauge to check to see if you need to add water. It's best to water with a drip or trickle system that delivers water at low pressure at the soil level. If you water with overhead sprinklers, water early in the day so the foliage has time to dry off before evening, to minimize disease problems. Keep the soil moist but not saturated.
  • Squash plants have both male and female flowers on the same plant. Male flowers will open first and the female flowers will open later.
  • Monitor for pests and diseases. Check with your local Cooperative Extension Service for pest controls recommended for your area.
  • Attract bee pollinators by planting daisies such as sunflowers, cosmos, zinnias and coneflower, and mints such as beebalm, sage, oregano and lavender. More bees mean more chances flowers will be pollinated and develop into fruits. Border squash plots with rows of beans, herbs, peppers and tomatoes.

Harvest Summer Squash & Preserving

  • Harvest when fruits are small and the skin is shiny. Harvest often. To keep summer squash producing pick all fruit at this stage. If fruit is allowed to mature the plant may stop producing.
  • To pick summer squash give the fruit a gentle twist until it snaps off.
  • Store summer squash in plastic bags in the refrigerator for up to a week.
  • Male squash blossoms are also delicious and sweet, try dipping in batter and frying.

Harvest Winter Squash & Preserving

  • Wait to until the fruit has matured to harvest.
  • Fruit will have a dull skin that is too hard to pierce with your thumbnail.
  • To harvest, cut fruit from the vine with shears leaving a 2- 3 inch stem on each squash.
  • Allow winter squash to cure in the sun for a week to harden skin.
  • Store winter squash in a cool dry place.

Squash, Summer, Sure Thing Zucchini Hybrid is rated 3.8 out of 5 by 21.
Rated 2 out of 5 by from Disappointed On April 25th, I planted 2 hills of these seeds and thinned the plants to 2 plants per hill. For two and a half months, all I had was sterile blossoms. Finally some blossoms formed with fruit. But my total harvest was only 8 zucchini before the vine borers killed all the plants. That was a complete waste of money and effort. At the end of August I planted more seeds in a different bed, and blossoms with fruit have developed. I hope I will be able to harvest some zucchini before frost kills the plants in October. I won't be ordering these seeds again.

Rated 1 out of 5 by from Mistake re Acorn Squash I ordered Early Hybrid Acorn squash in the spring. The package I received was labeled correctly, however I planted the seeds and when the plants grew to maturity it wasn't acorn squash at all but it was zucchini! I had also ordered the Summer Sure Thing zucchini hybrid which did produce zucchini. Needless to say I had way too much zucchini!

Rated 1 out of 5 by from 30 Percent Gemination Very disappointing experience. Only two out of six seeds germinated and growing slow and sickly. My other zucchini varieties germinated 100 percent and are growing fast and strong.

Rated 4 out of 5 by from Good plant that produces well The Sure Thing zucchini squash is one of the several squash plants in my garden this year. While it doesn't get as much sunlight as the other squash, it still produces a hefty amount of zucchini for me! What's even crazier is that despite getting a ton of its stem eaten, poked, smashed, and cut out as resultant of a month-long battle between squash vine borers and myself, this zucchini plant is still chugging along. It definitely is a fighter. The only qualm I have is that while it produces a lot, I find the taste to be a little boring, as far as zucchini goes. Otherwise, great hardy plant!

Rated 2 out of 5 by from Not my favorite, but starts nice and early. It did come on fast and hard, but seemed to fade. It did continue to produce for months, but not at the rate it started at. The plant stayed healthy, but the yield just tapered off.

Rated 4 out of 5 by from Getting Fair yields even with a late start Due to buying a house that took longer than expected I didnt get the transplants in the ground until mid June and they were certainly a good 2 weeks over due to be planted and were not in the most vigorous shape. They rebounded and produced a wave of fruits late July, a week and nothing and now I have 2 or 3 more fruits growing. I have 4 plants, 3 appear to be this variety. The other one is either a tiger hybrid or camoflage hybrid. No big deal here since I think most zukes taste the same. The problem is that I always have this problem with Burpee not having quality control with their seeds, particularly squash. Ive grown fordhook in the past and got some of those same stubby striped things in those seed packets also. I have 2 jack be little plants this year I grew from seed also OR so I thought. One plant is but the other one is growing round white things

Rated 4 out of 5 by from I was left wanting more... This Zucchini was quite the delicious treat. I had a lot of Zucchini in the beginning but the plant itself just died very quickly. I was left wanting more because usually I am up to my ears in Zucchini, but I would recommend this Zucchini for its taste and beautiful markings.
