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, Summer, Cosmos Hybrid is rated out of 5 by 4.Rated 2 out of 5 by Glenwood764 from WTF? Ordered a packet of these Cosmos summer squash seeds, which are supposed to be straight-neck, smooth skinned, and zucchini-like. They are none of these. I was expecting fruit at least similar to those pictured. Instead, I got a crookneck, thick skinned fruit with large bumps, and looking nothing like these pictures. I figured, what the heck, I'll give them a try. Turns out the skin is very tough and unpleasant to eat, compared to a zucchini. Even when picked very small with the blossom still on the end, the mushy seed chamber takes up 60%-70% of the body of the fruit, and is unpleasant to eat when steamed. The overall flavor is bland, not very sweet, with none of the "nuttiness" described. So I tried a more mature fruit. It had even thicker, tougher skin, 70-80% seed chamber taking up the volume of the fruit, with no improvement in flavor. The plants are vigorous, quickly out growing their spot, and are producing prodigious quantities of useless, mediocre fruit. Definitely not worth the money, time, or work to grow these! Certainly NOT AS DESCRIBED!Date published: 2015-08-06Rated 1 out of 5 by SDGardener from Problematic start 1st pkt of seeds dampened off, 2nd pkt didn't germinateDate published: 2015-03-18Rated 5 out of 5 by CrabbyDollfin from Great Yellow Squash I felt like I needed to write a review since this squash is definately deserving of a good review. This is a great summer squash and so far as been the best i've grown. The plants are open with large leaves and very easy to pick. We planted them closer than recommended but had no trouble at all with them overcrowdiing each other becuase they stand partially upright. Prolific producer and great fruit. We sautee them with onion and garlic and green pepper with scrambled eggs, or fsautee them with onion and olive oil for dinner, also used them as a layer in lasagna. There is nothing but good things to say about this item. Flavor is great. Once they start producing fruit the fun begins.Date published: 2014-07-12Rated 4 out of 5 by HiDesert from Pretty good These didn't do too bad for me this year. Pretty good production, although they did slow down for me way before my zucchini did. They are a little more compact than the zucchini plants. All in all a good product.Date published: 2013-08-24
