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, Butterstick Hybrid is rated 4.8 out of 5 by 26.
Rated 5 out of 5 by from I call it "Zucch-zilla" So this was a VERY odd year for squash. Vine borers found my garden for the first time ever. We had record rainfall in April, May, and June followed by extreme heat and little to no rainfall in July. I had to wait until May 15 to put out all my cucurbits because it was still 38 degrees in late April, when I should've been starting these. I start seed inside due to having lots of birds that have actually scratched up some melon seedlings in the past. Long story short - I planted about 12 plants in a 4' x 12' bed that was well prepped (I meant to thin them to 6 plants). Think I overdid it with the lime (hit it pretty heavy with Jobe's organic AND bone meal since I'd grown tomatoes pretty unsuccessfully in the same bed the prior year). Was trying to get the pH down - it had measured 5.5 the year before and I'd done nothing to adjust it. Think I went too far in the opposite direction because I had trouble with Pic N Pic throwing TONS of small shriveled squash. Pollination was also an issue due to all the rain. GRANTED, I was forced to pull the Burpee's Best Hybrid Zucchini before I got any fruit due to the vine borers. I also pulled the Pic N Pic just after independence day because only 1 of the 4 plants was producing, and there were voids around the seeds. Found vine borers in them as well. I had problems with squash bugs last year, and there's a few this year I'm barely staying ahead of, but there's an army of toads helping me out due to all the rainfall early in the season. ANYHOW, it's July 18 and the only significantly productive plant that was started just over 2 months ago has yielded around 25 of these buttery awesome zooks. The one plant puts it on FAST - anything around 6" would be darn near 15" by the time I'd get home at night. But even the large fruit was tasty and the seeds weren't a problem. I'm ALMOST tired of Cheese Please Squash casserole. Wait, no I'm NOT. DISCLAIMER - Burpee's info says the spread is 18" - my experience was closer to 18'. Realistically, when I remove the vine when it quits producing, it's probably be around 8-10' long and the leaves spread nearly 4' out away from the vine. See pics for details. The heat will cause some green streaking on the fruit. Used some Gypsum and Jobe's granular around the time it really started taking off. 2 fruit / day.

Rated 5 out of 5 by from Beautiful, Delicious, Prolific, and Cruel This is the first year that I've had luck with squash/zucchini--it's the first year I've tried Butterstick, and only my second year with a garden in the ground rather than pots. I planted four of these, plus two green zucchini (also from Burpee, but old seeds, nothing special). These plants are twice as big as the greens and are yielding at least three times as much squash, plant-for-plant. A couple got bigger than I planned on allowing, but they were still tender and delicious. My one point of caution, especially if you are gardening with children, as that the plants are very spiny. My shins were covered in scratches from late June through mid July, and now that it's August, my forearms are in rough shape. If you space your plants appropriately and are better than me about wearing your gardening gloves, it shouldn't be an issue. I stake my plants, so I've interacted with the spikes far more than the average gardener will, but they're intense enough to be noteworthy. I'm excited to grow these again next year (and will replace my old, boring green zucchini with the green tiger ones from Burpee).

Rated 5 out of 5 by from Great Producer and Overall Healthy Plant I enjoy planting zucchini and this variety far exceeded my expectations. The zucchini plants which I started from seed are healthy and produces delicious zucchini. This Butterstick variety actually outperformed my favorite yellow Summer Golden zucchini. I will be planting them both next year and we will see which variety wins next year. Definitely will be purchasing more of the Butterstick.

Rated 5 out of 5 by from Burpee Butterstick is a champ! I took a chance & planted seed when Omaha had a brief warm spell in late April. It germinated like a champ & now there already are 10+ baby squash that will be ready to pick by mid-June!

Rated 5 out of 5 by from Couldn't keep up with them!! Decided to buy this squash growing season 2017. These plants were AMAZING!! I could not keep up with all the squash it produced! The plants grow rapidly and have huge leaves that easily take over, keep that in mind when placing the plants. The fruits would double and triple in size in just a few days. The taste was amazing and a favorite to everyone I gave them too. Had a minor issue with squash bugs, but placed some potted mint plants in the area and that got rid of them.

Rated 5 out of 5 by from large, healthy plants I bought this and started the plants in my greenhouse along with other vegetables. When I transplanted them into my garden, this variety larger than my other zucchini plants and is delicious!

Rated 5 out of 5 by from The Butterstick is Back I am very glad you brought the butterstick back. You had it years ago and I liked it then. My plants have died off now. I had 3 heels I planted 3 seeds in each heel. They did real good I averaged 5 to 6 1-1/2"to 2" dia. x 7"to 8" long every day.THANK YOU FOR BRINGING THE BUTTERSTICK BACK Gary
