About Mashed Potatoes Acorn Winter Squash Seeds
Cucurbita pepo (hybrid)
An acorn type squash with stark white skin and nearly white flesh. Fruits are 1-1.5 lbs on highly productive plants, typically producing three to four fruits per plant. Vines are compact and most fruit are found on the crown set. The crown set is the first female flowers produced before vining starts. This means that "Mashed Potatoes" produces more female flowers earlier in its growth stage. Fruits will still appear on longer vines, just less of them. Color of the fruits hold into late fall.

Coverage & Planting Details
| Coverage | This packet sows up to 6 mounds. |
|---|---|
| Row Spacing | 3'-4' |
| Seed Depth | 1/2"-1" |
| Seed Spacing | 2-3 seeds per mound |
| Thinning | When 3 leaves, thin to 1 - 2 plants per mound |
| Germination | 5- 10 days |
| Start Indoors | Not recommended except in very short growing seasons, 2 to 4 weeks before transplanting. Roots are sensitive to disturbance; sow in biodegradable pots that can be planted directly into the ground. Transplant when soil temperature is at least 60°F. |
| Direct Sow | RECOMMENDED. 1 to 2 weeks after your average last frost date, and when soil temperature is 70°-85°F. |
| Special Care | To help protect plants against common pests like squash vine borer and cucumber beetles, use floating row covers, and remove covers when plants begin flowering. To further protect against vine borers, you can also cover the base of the stems near the ground with mulch, foil, or fabric material, as the base of the stem is where insect eggs are laid. Squash plants are susceptible to fungal disease, too, so make sure plants have ample space for air circulation. Sowing pollinator-attracting plants near squash can assist in proper pollination, resulting in a bigger harvest and well-shaped fruit. |
| Growing & Harvesting | Harvest when the squash's rind is hard enough that you can't dent it with your fingernail and before first frost. Cut stem, (don't break it off) leaving 2" of stem attached, which keeps the squash whole, leaving no opening for infection. Though fruits are hard and may seem indestructible, treat them gently; bruising can spoil squash. Harvesting Blossoms: Look for pollen-producing flowers that have long stems and harvest just before use (fruit-producing flowers have a very small, developing squash at the base of the flower and shorter stems). |

- Erica M.MI, United StatesVerified BuyerRated 5 out of 5 stars9/17/26Cute! These are just so cute!!!
Zone 6B backyard/raised bed gardener here, pretty new to the gardening scene. I was a little chaotic in my planting this year and direct sowed a few weeks after memorial day. They required very little space to grow, and flowed off the edge of my garden bed where I had some bare space. Read- my gardening efforts are "if it lives, great, if it doesn't make it, I wont even notice" kind of thing. These little things were all for it. Germination went well, the plants flourished, and they took up very little space. I now have the CUTEST little white squash ready for picking, each plant was pretty small in comparison to the amount of little treats it gave me.
These were my happy little surprise this year and I will definitely keep growing these.

Great products, selection and with quick service!
- LauraVerified ReviewerRated 5 out of 5 stars8/6/26Amen to this Superior Squash!
I second all the other 5 Star reviews. It's way better than original mashed potatoes. It takes very little butter and salt to get an amazing dish. I only have 1 plant, but so far it's pumped out 6 babies. Plan to sow many more next year! Thank you BI for offering this one!

- Marina M.Verified BuyerRated 1 out of 5 stars7/30/26None of the seeds germinated for me.
I am a regular buyer of this seed company. Sadly, not one single seed germinated for me. I'm at a loss here. I have a beautiful, vibrant garden and have several squash plants growing. I tried in the ground, in a raised bed. I tried a few weeks apart. Nothing. I'm reading the wonderful comments and have serious FOMO. I have 2 more packets in my cart. Last chance. I'm in Southern California. Los Angeles County.
