Why Growing Cucumbers in Wisconsin is a Great Choice 

You should consider growing cucumbers in Wisconsin because they thrive in the state’s continental climate with warm, humid summers and cold, snowy winters. Cucumbers prefer temperatures between 70 and 85 degrees Fahrenheit, making them well-suited to Wisconsin’s summer weather. However, it is important to note that cucumbers cannot tolerate frost, so it is recommended to plant them after the danger of frost has passed, typically in mid-May.

When choosing cucumber varieties for your garden in Wisconsin, you have a few options. Pickling cucumbers are small and crisp, perfect for pickling. Slicing cucumbers are larger and have a milder flavor, great for eating fresh or adding to salads. Burpless cucumbers are long and thin with a delicate flavor, ideal for fresh eating. Consider the intended use (pickling or fresh eating) when selecting a cucumber variety.

Before planting your cucumbers in Wisconsin soil, make sure the soil is well-drained and fertile. If the soil is heavy or clay-like, amend it with organic matter like compost or manure to improve drainage and nutrient content. Testing the soil before planting can help determine any nutrient deficiencies that may need addressing.

Once your soil is prepared, and the danger of frost has passed, it’s time to plant your cucumber seeds or seedlings outdoors. Cucumbers need full sun exposure, at least 6 hours per day. Space cucumber plants about 2 feet apart to allow room for growth.

Cucumbers require regular watering throughout their growing season. Deep watering encourages deep root growth and prevents diseases; therefore, it’s best to water them deeply during dry periods. Fertilizing cucumbers with nitrogen-rich fertilizers before planting will help promote healthy growth.

Harvesting cucumbers should be done when they reach around 6-8 inches long for optimal flavor and texture. Consider using insecticidal soap, ladybugs, row covers, or insecticides to control pests such as aphids, cucumber beetles, and squash bugs.

Growing Zones in Wisconsin

When planting cucumbers in Wisconsin, it is important to consider the growing zones. Wisconsin is divided into four main growing zones: Zone 3 in the north, Zone 4 in central areas, and Zones 5 and 6 in the southern part of the state. These growing zones are determined by factors such as average annual minimum temperature and frost dates.

Knowing your specific growing zone is crucial because it helps you determine the best time to plant cucumbers. In Wisconsin, it is recommended to plant cucumbers after the danger of frost has passed, typically around mid-May. However, if the weather is still cool after mid-May, you can start your cucumber seeds indoors and transplant them later when the weather warms up.

In addition to considering your growing zone and timing, there are other factors to keep in mind when planting cucumbers in Wisconsin. Choose a cucumber variety that suits your preferences – pickling cucumbers for pickling, slicing cucumbers for fresh eating or salads, or burpless cucumbers for a delicate flavor. Ensure that you have well-drained and fertile soil by amending heavy or clay-like soil with organic matter like compost or peat moss.

When planting your cucumber plants outdoors, make sure they receive at least six hours of sunlight per day and space them about two feet apart. If space is limited, you can train them to grow up trellises or fences to save space and make harvesting easier. Water regularly and deeply during dry periods to prevent drought stress.

When to Plant Cucumber Seeds in Wisconsin

Consider starting your cucumber seeds indoors if the weather in Wisconsin is still cool after mid-May. Starting your seeds indoors gives them a head start and ensures that they have enough time to mature before the first frost.

To start your cucumber seeds indoors:

  1. Fill seed trays or pots with a good quality seed starting mix.
  2. Plant one or two seeds per pot, about half an inch deep.
  3. Keep the soil moist but not waterlogged, and place the trays or pots in a warm location where they can receive plenty of sunlight or under grow lights.

Once the seedlings have grown their second set of true leaves, you can transplant them into larger pots or containers. When all danger of frost has passed, and the weather has warmed up, you can then transplant your cucumber seedlings outdoors into your garden.

When choosing a location for planting cucumbers outside, ensure they receive at least 6 hours of direct sunlight each day. Cucumbers also need well-drained soil that is rich in organic matter. Before transplanting, prepare the soil by adding compost or aged manure to improve its fertility and drainage.

When planting your cucumber seedlings outdoors, space them about 2 feet apart to allow room for growth and airflow between plants. You can also consider using trellises or fences to support the vines and save space in your garden.

Remember to provide regular watering for your cucumber plants, especially during dry periods. Deep watering is important as it encourages deep root growth and prevents diseases.

How to Protect Cucumbers from Frost

To protect your cucumbers from frost, there are a few steps you can take.

First, if you have potted cucumber plants, simply bring them indoors when a frost is predicted. This will give them the protection they need from the cold temperatures.

For cucumbers planted directly in the ground, covering them with burlap can be effective. Wrap the burlap around the plants and secure it at the base to keep it in place. This creates a barrier that traps heat and prevents cold air from reaching the plants.

It’s important to closely monitor weather conditions and be prepared to protect your cucumbers if late frosts occur. Keep an eye on local weather forecasts and be ready to take action if necessary.

In addition to frost protection, it’s also crucial to plant your cucumbers at the right time for optimal growth. Planting them after the danger of frost has passed, usually mid-May, will reduce the risk of damage. If you live in an area with cooler spring temperatures, consider starting cucumber seeds indoors and transplanting them later when it warms up.

Common Mistakes When Growing Cucumbers in Wisconsin

One common mistake when growing cucumbers in Wisconsin is neglecting to plant them early enough, which can result in small or no cucumbers. Cucumbers need warm temperatures between 70 and 85 degrees Fahrenheit to thrive, and they cannot tolerate frost. It is important to wait until after the danger of frost has passed before planting cucumbers outside, which typically occurs in mid-May in Wisconsin. However, if the weather is still cool at that time, consider starting cucumbers indoors and transplanting them later.

Another mistake to avoid is inadequate spacing between cucumber plants. Cucumbers should be spaced about 2 feet apart to ensure proper air circulation and prevent overcrowding. Insufficient spacing can lead to disease transmission and hinder growth.

Additionally, it’s crucial to provide cucumbers with regular watering, especially during dry periods. Cucumbers require deep watering to encourage deep root growth and prevent diseases. Watering in the morning allows the leaves to dry before nightfall, reducing the risk of fungal infections.

In Wisconsin, watch out for common pests such as aphids, cucumber beetles, and squash bugs. Control these pests using insecticidal soap, ladybugs, row covers, or insecticides as needed.

Lastly, neglecting nitrogen-rich fertilizers can also impact cucumber growth. Before planting cucumbers, add nitrogen-rich fertilizer to the soil for optimal nutrition. Side dressing with compost or manure during the growing season can further enhance their growth.


In conclusion, growing cucumbers in Wisconsin can be a rewarding and delicious endeavor. By considering the climate and timing for planting, choosing the right variety, preparing the soil, and providing proper care and maintenance, you can enjoy a bountiful harvest of fresh cucumbers.

Remember to protect your plants from frost, watch out for pests, and harvest them at the right time. With these tips and resources at your disposal, you’ll be well-equipped for growing cucumbers in Wisconsin successfully.
