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 Zucchini Hybrid is rated 4.8 out of 5 by 25.
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
