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, Gadzukes! Zucchini Hybrid is rated 4.4 out of 5 by 16.
Rated 5 out of 5 by from Best zucchini I've grown this zucchini for years and will keep growing it next year. We use it in salads ,sautéed,baked and zucchini bread. It doesn't get watery like others even when gets large.

Rated 5 out of 5 by from I have planted gadzukes for many years and love it I ended up with 3 plants started inside. One didn't come up. Now that they are bearing, one isn't a gadzukes. It is striped but no ridges stick out. It is just smooth. It tastes good, but I love the ridges for slicing etc.

Rated 5 out of 5 by from Flavorful! We have tried other zucchini but always insist on growing Gadzukes! as well. While not as productive as other zucchini (a plus?), Gadzukes! delivers on flavor over other zucchini. While to trailing, this is a large-leafed plant and will get to about four feet tall, so give it a little extra room than regular zucchini.

Rated 1 out of 5 by from Did not like this squash I grew this several years ago and was not impressed. The plant was very prolific, but the texture of the flesh was soft and mushy. The flavor wasn't very good, either.

Rated 5 out of 5 by from Best Zucchini By Far My wife and I simply won't plant another variety of zucchini than Gadzukes!.. When I ran out of seeds a few years ago, I thought Gadzukes were just another Italian zucchini. Wrong! The flavor was never the same and the ribbing didn't stand out like this one does. We like that the seeds stay small and the fruit stays smaller in diameter when it gets older They just get longer. There is a nice, nutty flavor. We love to just dip them in eggs, coat them in flour, then fry them. It's not low-fat but BOYdo they taste great. Even our two kids just gobble them down. We've been growing them for almost 10 years and will never switch.

Rated 5 out of 5 by from Great producer I tried several different varieties of Zuchs this year this was the best producer. The Italian ribbed has a slightly better flavor if you tasted them raw but Gadzukes was definitely the best producer. Mine did not have the very ribbed appearance shown in the picture in fact once picked it was hard to tell the difference between the Italian ribbed and the Gadzukes. Love this zuchinni and will be planting this next year.

Rated 5 out of 5 by from Best Zuke flavor This by far my favorite zucchini for flavor. Easy to grow and even the large ones have great flavor grilled or fried. A definite must if you are a zucchini lover.

Rated 3 out of 5 by from Very cool looking Zuke These were very good tasting and would grow like crazy. Unlike the standard Zuke, the skin would get tough as they would get somewhat bigger. I'd love to chop up the small ones into salads.
