Growing herbs outside in a pot in Wisconsin” is a smart and satisfying way to enjoy fresh herbs, even with the state’s tough climate. Pots can be easily transported indoors when there are chilling winters or off-season snowfalls.
In addition to that, they can utilize some warm places indoors or some protected areas outdoors so that there is an extended period of cultivation.
Because of the wet spring season in Wisconsin and its in-ground garden limitations to expose more soil, pots are suitable with this climate change since they are raised well off the ground and have proper drainage.
They can be seen as great vessels for gardening even in small balconies or large patios, as pots of herbs can be easily planted to provide herbs all year round.
In this blog post, we will explore how to grow herbs outside in a pot in Wisconsin, the selection of appropriate pots and soils, and the maintenance of the plants in each season.
Why Grow Herbs Outside in a Pot in Wisconsin?
Growing herbs outside in a pot in Wisconsin offers many advantages. The state’s climate brings warm summers but very cold winters, with temperatures ranging from 70°F to 85°F (21°C to 29°C) in summer and dropping as low as -20°F (-29°C) in winter, especially in the north.
Spring and fall can be unpredictable, with warm days and cool nights, and the growing season is short, from May to September. By using pots, you can move herbs to sunny spots in cooler months and bring them inside during frost.
Pots also allow for better soil control, helping herbs grow longer and stay fresh, even with Wisconsin’s challenging weather.
Choosing the Right Herbs for Pots in Wisconsin
Choosing the right herbs for pots in Wisconsin means picking ones that can handle changing weather. Basil, mint, chives, thyme, oregano, parsley, rosemary, cilantro, lavender, and sage are all good choices.
These herbs grow well in containers, so you can move them inside if it gets too cold.
Mint, chives, thyme, and sage are especially hardy and can handle Wisconsin’s chilly weather and light frost. With these tough herbs, you’ll have fresh flavors to enjoy all season!
Wild Herbs in Wisconsin
Wild herbs in Wisconsin include plants like wild bergamot, echinacea, goldenseal, and wild ginger. These herbs grow naturally in the area and can be found in places like forests and fields. People often use them for cooking or for natural remedies.
Medicinal Herbs in Wisconsin
Five medicinal herbs commonly found in Wisconsin are echinacea, goldenseal, wild ginger, wild bergamot, and American ginseng. These herbs are valued for their therapeutic properties and can be used to support immune health, digestion, and overall wellness.
Selecting the Right Pot to Grow Herbs Outside in a Pot in Wisconsin
Picking the right pot for your herbs is important for healthy growth. The pot size should match the herb’s roots. Basil and mint need larger pots, around 12 inches wide, while thyme and chives grow well in smaller pots, about 8 inches wide.
Avoid pots without holes, as they will cause the water to accumulate. Pot material should also be considered. Terracotta pots are porous and allow ventilation, but the moisture condition changes very quickly.
Watering with plastic and ceramic pots is uncomfortable since they keep more water for a longer time. With proper size of the pot, drainage, and the right material, your herbs will be healthy and grow beautifully.
Best Location to Grow Herbs Outside in a Pot in Wisconsin
The best location for optimal growth of potted herbs in Wisconsin is where they get 6-8 hours of direct sunlight each day. A south-facing wall or a sunny patio is great for this.However, ensure that the spot is protected from strong winds.
You can place pots along walls, fences, or large structures to block the wind but still allow good air flow. Also, a balcony or raised deck is a good choice, especially if it faces south or southwest. This allows for sunlight and some shelter from harsh weather.
In addition, ensure the herbs are in a position where watering is easy and near the kitchen for convenient plucking. You should be able to pick the pots up and move them in case of unfavorable weather or in case of a late frost.
How to Plant Herbs in Pots
To plant herbs in pots, start by choosing containers with drainage holes. Use a good potting mix made for containers, not garden soil, as it can get too compacted and won’t drain well.
To make the soil better for drainage, mix in about 25% perlite or coarse sand. Add a small amount of slow-release organic fertilizer for steady nutrients.
Before planting, moisten the potting mix well. Fill the pot, leaving 1-2 inches at the top for watering. For transplants, dig a hole bigger than the root ball.
Place the herb at the same depth it was in the old container. Gently press the soil around the roots to remove air pockets, but don’t pack it too tight.
For seeds, follow the packet’s instructions. Usually, plant them twice as deep as their size. After planting, water the herbs well until water comes out of the holes.
Add a light layer of mulch around the plants, but keep it away from the stems. This will help keep the soil moist and at a good temperature.
Caring for Your Herbs Garden in Pots
Watering Your Potted Herbs
Herbs in pots need regular watering. Check the soil every day by sticking your finger about an inch deep. If the top is dry, water thoroughly. Be careful not to overwater, as this can cause root rot.
During hot summers in Wisconsin, water every 1-2 days. In cooler months, water less often. Always make sure water drains from the bottom of the pot.
Fertilizing Your Herbs
Use a balanced, water-soluble organic fertilizer. Mix it at half strength and apply every 4-6 weeks during the growing season. Alternatively, you can add slow-release organic granules when you first plant your herbs.
Pruning Your Herbs
Regular pruning helps herbs grow better. Pinch back the tips of herbs like basil, oregano, and mint to make them bushier.
If you see flower buds, remove them unless you want to save seeds. Never cut off more than one-third of the plant at once.
Preparing for Cold Weather
When the temperature drops below 40°F in Wisconsin, move your herbs inside. Put them near a sunny window or in a heated greenhouse.
For hardy herbs like thyme and sage, you can move them to a sheltered spot outside, like against a house wall.
Protect them with straw or bubble wrap to keep them warm. Alternatively, you can transplant them into the ground for winter.

When to Plant Herbs in Wisconsin
In Wisconsin, the best time to plant herbs outdoors is after the last spring frost. This usually happens between mid to late May, depending on where you live.
Wisconsin has a short growing season of about 120-180 days. To get a head start, many gardeners plant seeds indoors 6-8 weeks before the last frost, usually in late March or early April.
You can use grow lights or place the seeds in a sunny window.
Hardening Off Indoor Plants
Before moving herbs outdoors, you need to “harden off” indoor-started plants. This means gradually exposing them to outdoor conditions.
Start by placing them outside for 1-2 hours in a sheltered spot. Increase the time outside each day over 7-10 days. This helps prevent plant shock.
Planting Outdoor Herbs
For warm-season herbs like basil and oregano, wait until the soil temperature reaches 65°F. Hardy herbs, like thyme, sage, and chives, can handle cooler temperatures.
You can plant them earlier, around early May. Use row covers or cold frames to protect them from unexpected temperature drops.
Pest Control and Troubleshooting
Common Pests and How to Control Them
Container herbs in Wisconsin can attract pests like aphids and slugs. To get rid of aphids, mix one tablespoon of mild dish soap with a gallon of water and spray it on the plants.
Ladybugs are also helpful, as they eat aphids. For slugs, use copper tape around the pots or sprinkle diatomaceous earth around the plants.
Troubleshooting Yellowing Leaves
If the leaves of your herbs are turning yellow, it might be due to overwatering or poor drainage. Make sure your pot has drainage holes, and reduce the watering frequency. Check the soil to see if it’s too wet.
Dealing with Wilting Leaves
Wilting leaves, even when the soil is moist, may be a sign of root rot. Carefully remove the plant from the pot and check the roots. Healthy roots should be white or light-colored, while rotting roots will appear brown and mushy.
Preventing Fungal Issues
To avoid fungal problems like white powdery mildew, ensure your plants have good air circulation and don’t water from above.
For white powdery mildew, mix one part milk with nine parts water or use a solution of baking soda and soap. Spray it on the leaves to prevent and treat the mildew.
Conclusion
