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 are “dioecious” having 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 & 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.

Squash, Winter, Waltham Butternut is rated out of 5 by 9.Rated 5 out of 5 by grenthumbs from wonderful we got so much squash we almost did not know what to do with it. Great tasteDate published: 2015-04-05Rated 5 out of 5 by FarmerTK from Patience Rewards Yes, the Waltham does seem to take forever but hang in there - it's worth it in the end. Two other things you should know from my experience: 1-you will be duped into thinking you're getting loads of squash because of all the flowers that appear, but only a few of those will actually result in 'bearing veggie'; and 2-the vines roam like a nomad - I had one find its way into and 3 ft up a cucumber trellis several feet away from the base, so give yourself plenty of room and keep steering the vines into desired confines. As far as harvesting goes, I read that you're supposed to wait until the stem (where it enters the squash) gets woody (looks drier and more brown than green) and that means you're looking at upwards of five months (at least here in NY) before you can start reaping what you sowed. The good thing is that brings you to the cusp of soup season. We've roasted and souped a few so far and they've been great.Date published: 2014-11-09Rated 3 out of 5 by kabijo from Nice vines, unripe fruit I agree witht the last review - takes a long time to get ripe, so far no luck and the days are getting cooler so we may not get one this year. The vines are beautiful though.Date published: 2014-09-18Rated 3 out of 5 by Peter1142 from Takes forever to get ripe fruit It took nearly 4 months to get a truly ripe fruit, and the vines seemed to only be able to handle one at a time. Fruit that has not fully ripened is tasteless. There is a lot that can (and did) go wrong in that time frame, such as skin rotting (which thankfully was superficial) and bugs eating them, and thunderstorms breaking off a vine. On the plus side, they proved to be resistant to the powdery mildew and squash vine borers that plagued my acorn squash and zucchini.Date published: 2014-09-09Rated 5 out of 5 by Parker from Excellent Squash This was the first type of squash I've grown and it did extremely well. Even with little maintence, I had numerous, medium to large size squash.Date published: 2009-09-23Rated 5 out of 5 by Yardner from Top quality Wow! The plants not only took over the garden, they had large wonderful fruits with small seed cavities. If you don't like the chore of cleaning out the seeds this plant is for you. It even did well during a drought and I could only water once every other week.Date published: 2008-10-22Rated 5 out of 5 by DAHLIA from OLD TIME FAVORITE This was my first time growing butternut squash, but I could remember my dad bringing butternut squash home from his garden. The vines for me produced squash early in the season and produce more squash mid season. The butternut squash had rich color and excellent taste. My crop will not last during the winter because it is so delicious. I can't wait that long to eat them. I definitely will plant again :)Date published: 2008-08-29Rated 5 out of 5 by Kronos from Always reliable... My family has been growing this variety in our garden for years. Very productive. With one mound of 2-3 plants there was always enough for our family of five and extra to share with neighbors and friends. Only problems we ever encountered were with deer snacking on them just before harvest time.Date published: 2008-07-23
