How do you winterize strawberry plants in Wisconsin?
Winterizing Strawberry Plants Protecting strawberry plants from winter’s cold temperatures is vital to ensure a crop of juicy berries next year. Winterizing strawberry plants isn’t difficult or expensive. It’s actually an easy chore on your garden to-do list.
Learn tips for winterizing strawberry plants. By the time fall frosts arrive, strawberry plants have already set buds for next spring’s flowers. Temperatures below 15° F can damage those new buds and diminish your berry crop next year. This is why it’s vital to winterize strawberry plants and protect them from cold winter air.
Another reason to protect plants is that, when soil repeatedly freezes and thaws, it tends to push plants up. This process is called heaving and puts plants at risk in several ways. First, it can expose plant crowns to drying air, freezing air temperatures and hungry critters looking for a winter meal.
Second, heaving can break roots, allowing them to be lifted completely out of soil. Either results in plant damage or death. Winterizing strawberry plants helps prevent heaving. Winterizing strawberry plants simply involves heaping mulch over plants so they’re not exposed to cold winter air. The trick is knowing when to apply the mulch.
You want to cover plants when they’re fully dormant. Cover too soon, and plants may fail to harden off, which means they’ll definitely be damaged by cold air. A too-soon mulch also risks rotting plant crowns. It’s safe to apply winterizing mulch to strawberry plants when the top one-half inch of soil has frozen and daytime temperatures stay consistently in the 20s.
- In mild winter areas, apply mulch once soil temperatures hit 40° F for three days in a row.
- Definitely winterize strawberry plants before temperatures dip below 20° F.
- Precise timing varies depending on region.
- Fine-tune the timing with a call to your local extension office.
- To winterize strawberry plants, heap a loose mulch over plants to a depth of 3 to 5 inches.
Use a material that won’t compact heavily. Good choices include straw, clean hay, bark chips, chopped cornstalks or cobs, evergreen branches or pine straw. Materials like leaves or grass clippings aren’t a good choice because they tend to mat. After mulch settles, it should still provide a 2- to 3-inch depth for best protection.
- Using a frost blanket to winterize strawberry plants is another great choice because it allows light to reach plants, which results in more flower buds being formed.
- The tricky part is that plants experience faster flower development in spring, which means they’ll be at greater risk for cold damage if you fail to protect plants when a late-season frost is predicted.
To winterize strawberry plants in a pyramid, apply mulch 6 to 8 inches deep. Wrap large strawberry pots or barrels with burlap and/or bubble wrap and stuff the top opening with straw 6 to 8 inches deep. Move strawberry jars into an unheated garage for winter.

A Seasonal Berry Guide for Wisconsin 
Berry picking is one of my favorite things to do in the summer. There’s something so satisfying about having a pail full of berries, carefully hand-picked and ready to eat. Every summer, I plan a picking day for each type of berry. Whether it’s heading to a local Wisconsin farm or searching for them out in the wild, I find berry picking to be a rewarding (and delicious) summertime hobby. 
Late June to early July | Strawberries Strawberries are the first berries to bloom! Due to the cooler weather this year, the strawberry farms here in Wisconsin are a bit behind schedule. Normally, you can pick strawberries from late June to early July.
Keep in mind, strawberries have one of the shortest seasons and only lasts 2-3 weeks. It’s easy to miss, so mark those calendars! Early July to September | Raspberries The middle to the end of summer is when you can expect to pick raspberries. They have a longer season than strawberries so there are plenty of opportunities to go picking and to try out new farms.
Mid July through August | Blueberries Next on the schedule blueberries! There doesn’t seem to be as many blueberry farms in Wisconsin compared to strawberry and raspberry farms. So I tend to go wild blueberry picking each year instead. Since they grow so low to the ground, wild blueberries are a little trickier to spot alongside the road.
Look for forest clearings and sunny hillsides. Blueberries also tend to prefer sandy soil, so northern Wisconsin is a great place to find them. Once you find a patch, you’ll be picking for hours! August and September | Blackberries Last but not least, blackberries! This is another berry that’s hard to find at a farm but fairly easy to find in the wild; especially in the Northwoods! Go for a slow drive down some backroads and look for blackberries growing along ditches and sunny hillsides.
Once you spot one blackberry patch, you’ll start noticing them everywhere! To give you an idea of what they look like, check out this Remember to check the berry farm’s Facebook page for the most accurate, up-to-date picking information.
