My new favorite

I don't change loyalties easily, and have long been a yellow crookneck devotee, but Cube of Butter is The One. Prolific, consistent, good even when it's gotten really large, with a buttery flavor that must have influenced its name. One plant is enough for my family with some left for the neighbors.

Great blossoms for frying and still plenty of squash

This is a garden standout - the blossoms are delicious stuffed with ricotta and herbs, battered and fried. The squash are yellow, tender and delightful, and make beautiful baby vegetables for dishes like pasta primavera. Highly recommend this one, and I'm not a zucchini fan. Give it a try!

Amazing squash!

After reading the two existing glowing reviews, I decided to give this variety a try. 100%, I agree with the other reviewers. Tender, tasty, healthy, prolific. In addition, it has proven both cold (for a squash) and heat tolerant. I have 2 of these in my garden (and recently started two more), I gave a couple to my mother-in-law who's a pro grower, and a couple to a friend who really struggles to get any harvest from any plant. All of us already have fruit from this variety! I've also got Suntripe and two types of scallop going, and this produced the fastest. The fruit is very tender and has a mild flavor. Eaten raw the flavor reminds me of snap peas, and cooked it is equally sweet and delicious. My husband and daughter, not big squash fans, both ate it happily. It's also a gorgeous pale creamy yellow, not bright like standard yellow zucchinis. The only slight negative is that it seems more prone to powdery mildew than the others (we had a lot of rain for our region, and it got very humid a few weeks back), but it doesn't seem to be harming the plant or the production. It's dealing very well with our Central Oregon cool nights, and with this terrible late June 2021 heat wave that's ponding the entire NW. It has fertilized and continued to produce even with temps soaring way over 100. I will absolutely grow this every year from now on, and I highly recommend it.

Best of the yellows

Even my 85 year old neighbor, a gardening pro who swore by traditional yellow crookneck, agrees. In every kind of NW summer, cool or hot, Cube of Butter has always been early, tender, tasty, and (of course) prolific. The flavor is so good that my zucchini hating spouse will gladly eat it, and the neighbors don't run from the overflow. This year I'm also growing Chiffon, and so far Cube of Butter has it beat. I can't tell much difference in flavor, texture or appearance, but Cube has been faster to produce, more prolific, and the seeds seem no larger at the medium sizes I'm picking. I agree with Jim's review on all counts.

Cucurbita spp. In the diverse family of squash are true nutritional powerhouses, encompassing a wide array of forms, flavors, colorations, and culinary applications. Squash are rich in the carotenoids necessary for vitamin A production and boast a wide complement of amino acids. While starchy, most of the carbohydrates in the fruit come from special polysaccharides, pectins, which have exhibited strong antioxidant, anti-inflammatory, and anti-diabetic, insulin-regulating properties.

Days to maturity are from date of direct seeding.

• Fertile, well-drained soil gives best results
• Squash is a warm season crop, so avoid planting too early; raised beds and plastic mulch help keep roots warm
• Squash are monoecious (bearing separate male and female flowers on the same plant) and require insect pollination
• Poor fruit set is often the result of inadequate pollination; plant bee attractant flowers

Direct Sowing
• Plant after frost danger when soil warms to 65°F
• Work in shovelful of compost and 1/2 cup TSC's Complete fertilizer into hill
• Keep soil evenly moist but not wet as too much moisture causes seed to rot
• Bush varieties: sow 3-4 feet apart
• Vining varieties: sow 4-6 feet apart

• Start indoors 3-4 weeks prior to anticipated transplant date in 4 inch pots
• Work in shovelful of compost and 1/2 cup TSC's Complete fertilizer into hill
• Transplant carefully as to not disturb roots

Insects & Diseases
• Common insects: Spotted and striped cucumber beetles, vine borers and squash bugs
• Insect control: Row covers and/or apply Pyrethrin
• Moschata species are resistant to vine borer
• Common diseases: See chart below; diseases vary by region
• Disease prevention: 3-4 year crop rotation, and fungicide applications

Harvest & Storage
• Summer squash: Harvest regularly when fruits are young to keep plants productive
• Winter squash: Leave on vine until fully mature, rinds should be firm
• When winter squash is mature cut stem leaving 2-4 inches remaining, gently wash in sanitizing solution; 10 parts water to 1 part bleach
• For best results move winter squash to a warm dry area 80-90°F to cure; see each type (below) for curing requirements
• Store winter squash at 50-60°F with 50-75% relative humidity and good air circulation

Curing Requirements
• Acorn: Curing not required; Stores 2-3 months
