Why Grow Summer Squash in Wisconsin
There are several reasons why it’s worth growing summer squash in Wisconsin.
First and foremost, Wisconsin’s climate is ideal for growing summer squash. The state provides the conditions for a successful harvest with its continental climate and four distinct seasons. Summers have an average temperature of around 80 degrees Fahrenheit, perfect for growing summer squash in Wisconsin. Additionally, the state receives a good amount of rainfall during these months, which is beneficial for the plants.
Another reason for growing summer squash in Wisconsin is the wide variety of suitable squash varieties available. Acorn squash, butternut squash, and pumpkins are recommended choices for this region. These varieties are tolerant of colder temperatures and shorter growing seasons that characterize Wisconsin’s climate. Depending on your purpose – whether it be decorative or culinary – you can select larger varieties with good color for decoration or smaller ones with excellent flavor for cooking.
Preparing the soil properly is crucial when growing summer squash in Wisconsin. Squash requires well-drained soil with high organic matter content. Adding compost to your soil is an effective way to improve its organic matter content. You can create your own compost by collecting yard waste and kitchen scraps or purchasing compost from local nurseries or garden centers.
Regarding planting time, it is recommended to plant summer squash in late May or early June after the last frost date has passed. However, it’s important to check with your local cooperative extension office or reliable online resources to determine the accurate last frost date specific to your location.
Once planted, caring for summer squash involves regular watering during dry periods and fertilizing every few weeks with a balanced fertilizer. Weeding around the plants will help prevent competition for nutrients.
Growing Zones in Wisconsin
Wisconsin is divided into different growing zones that can affect the success of growing various plants. It’s important to understand your specific zone in order to choose the right plants for your garden. Here are some key points about growing zones in Wisconsin:
– Wisconsin is divided into four USDA hardiness zones: Zone 3, Zone 4, Zone 5, and Zone 6.
– Each zone has its own average minimum winter temperatures, which determine what plants can survive in that area.
– Zone 3 has the coldest winters, with average minimum temperatures ranging from -40°F to -30°F.
– Zone 4 has slightly milder winters, with average minimum temperatures ranging from -30°F to -20°F.
– Zone 5 has even milder winters, with average minimum temperatures ranging from -20°F to -10°F.
– Zone 6 has the mildest winters in Wisconsin, with average minimum temperatures ranging from -10°F to 0°F.
– The growing season also varies across these zones:

– Zones 5 and 6 have longer growing seasons with fewer frost risks.
Knowing your specific zone can help you choose plants that are suitable for your climate and ensure their successful growth. It’s also important to consider factors like soil type, sunlight exposure, and rainfall patterns when selecting plants for your garden.
When to Plant Summer Squash Seeds in Wisconsin
To ensure successful growth of your summer squash seeds in Wisconsin, it’s important to plant them after the danger of frost has passed. Summer squash is a warm-season crop that thrives in temperatures between 70 and 85 degrees Fahrenheit. Planting too early can expose the tender seedlings to frost damage, stunting their growth or even killing them.
In Wisconsin, the average last frost date varies depending on your location. To determine the best time to plant your summer squash seeds, consult local resources such as cooperative extension offices or online gardening forums for accurate information specific to your area.
Once you’ve determined the appropriate planting time, prepare your soil by loosening it with a garden fork or tiller. Remove any weeds or debris and amend the soil with compost or well-rotted manure to improve fertility and drainage.
When planting summer squash seeds, space them 24 to 36 inches apart in rows or hills. If planting in hills, create mounds of soil about 48 inches apart and sow four to five seeds per hill. Plant the seeds about an inch deep into well-drained soil.
After planting, thoroughly water the seeds and keep the soil moist but not waterlogged throughout the growing season. Mulching around the plants can help retain moisture and suppress weeds.
As your summer squash plants grow, provide support for their vines by using trellises or stakes. This will prevent them from trailing on the ground and reduce disease issues.
Harvesting can begin when the fruits are small and tender, usually around six to eight weeks after sowing. Regularly harvest mature squash to encourage continuous production.
How to Protect Summer Squash from Frost
Once the danger of frost has passed, it’s important to protect your summer squash from any potential frost damage. Here are some practical tips to help you safeguard your plants:
Covering the Plants:
– Use blankets, sheets, or tarps to cover your squash plants when frost is forecasted.
– Support the covering so the plant/leaves are not directly contacting the cover.
– Secure the covers with stakes or rocks to prevent them from blowing away.
– Ensure that the covers reach all the way down to the ground and completely cover the plants.
Providing Heat Sources:
– Place small heaters or heat lamps near your squash plants to provide additional warmth during cold nights.
– Be cautious when using heat sources and follow safety instructions carefully.
Remember, even a brief exposure to freezing temperatures can harm your plants and hinder their growth. It’s essential to stay vigilant and monitor weather forecasts regularly during those early spring nights when frost is still possible.
Additionally, practicing good garden hygiene by removing fallen leaves and debris from around your plants can help prevent pests and diseases that thrive in damp environments. Keep an eye out for signs of powdery mildew or cucumber beetles, as they can negatively impact your squash crop. Treat affected plants with organic insecticidal soap or neem oil according to package instructions if necessary.

Common Mistakes When Growing Summer Squash in Wisconsin
One common mistake people make when growing summer squash in Wisconsin is not providing enough sunlight for the plants to thrive. To ensure successful growth and yield, it’s important to give your summer squash plants the right amount of sunlight. Here are some practical tips to help you avoid this mistake:
– Choose a sunny location: Select a spot in your garden that receives at least 6-8 hours of direct sunlight daily. Summer squash plants require ample sunlight for proper photosynthesis and fruit production.
– Clear away obstructions: Trim or remove any overhanging branches, tall weeds, or structures that may cast shade on your squash plants. This will allow them to receive maximum sunlight throughout the day.

When to Start Summer Squash Indoors
Starting your squash indoors gives them a head start and allows you to extend the growing season, which is important when growing summer squash in Wisconsin. Begin about four to six weeks before the last frost date in Wisconsin, which is typically in late May or early June.
Fill small pots or seed trays with a good-quality potting mix. Plant one seed per pot or cell, placing it about an inch deep into the soil. Water gently but thoroughly after planting.
Place the pots or trays in a warm area where temperatures stay around 70-85 degrees Fahrenheit during the day and above 60 degrees at night. You can use heat mats to provide additional warmth if needed.

Once the seedlings have sprouted and developed their first set of true leaves, you can begin fertilizing them with a balanced liquid fertilizer diluted according to package instructions. This will help promote healthy growth.
When all danger of frost has passed, and outdoor temperatures consistently reach around 60 degrees Fahrenheit, your seedlings will be ready for transplanting into the garden. Harden off the plants by gradually exposing them to outdoor conditions over a period of one to two weeks before planting them in their permanent locations.
How to Transplant Summer Squash Seedlings Outside in Wisconsin
Now that you have started your summer squash seedlings indoors, it’s time to transplant them outside in Wisconsin. When growing summer squash in Wisconsin, transplanting seedlings can be a critical step in ensuring their success, so it’s important to do it correctly.
