How do you save strawberries for the winter?
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.
What does frost do to strawberries?
Strawberries Frost Tolerance and Injury Symptoms – Strawberry flower buds and fruit are susceptible to frost injury any time after bud break (-1ºC or lower). Frost damages the center of the flower with the center turning black while the petals and leaves appear uninjured.
The blackening occurs within a few hours to one day after the frost. Frost can also damage the developing fruit, deforming the berries. Frost injury rarely causes complete crop loss because the strawberry plant produces flowers over a two to three week period. The first flowers to open are the largest and face the greatest risk of frost injury.
Closed buds are also sensitive to frost damage. Frost losses can range from 20 to 80% depending on the temperature and the duration of the frost, the cultivar, vigor, stage of development and the weather preceding the frost. Strawberry flower buds can tolerate lower frost temperatures depending on its stage of development.
When should I uncover my strawberries?
Remove straw in the spring – A strawberry field immediately after straw was removed in spring. Remove straw from strawberries when they first begin growing in the spring. Delaying mulch removal too long will delay harvest and decrease yield. However, removing it too early increases the risk of spring frost damage. Time straw removal based on:
Strawberry leaf growth under the straw. Soil temperature and moisture. The weather forecast.
To decide when to remove straw, check for strawberry leaf growth under the straw every couple of days starting in early April. Remove it once new leaves emerge, and do not prolong removal very long past that point. New leaves are those that are emerging from the crowns.
They may be green or yellow. Early fruiting varieties typically produce leaves earlier than late-season varieties. Check the soil temperature with a soil thermometer. The top 2-4 inches of soil should be above 40 degrees F before removing straw. Check the weather forecast, and plan straw removal accordingly.
If a string of very cold days are in the short-term forecast, consider waiting until the coldest temperatures have passed before removing the straw. Sometimes, warm spring temperatures make plants exit dormancy early, increasing the chance that they may be affected by a late spring frost later on. A hand-built hydraweeder to remove straw.

How do you freeze strawberries for months?
Basic method for freezing strawberries –
Prep the strawberries by washing them in cold water and patting dry with kitchen paper.Cut and discard the stems, then freeze whole or cut to desired size.Lay the prepared strawberries on a tray and put in the freezer and until solid. Once frozen, transfer to labelled resealable freezer bag, ensuring you remove any excess air before sealing. Frozen strawberries are best used within six months.
How do you store strawberries for the longest life?
How to Store Strawberries – When stored properly in the refrigerator using one of the below methods, strawberries should stay fresh for up to one week. Always examine your berries for mold and other signs of spoilage before eating them.
Place in air-tight glassware: Transfer unwashed strawberries into a glass food storage container or mason jar and make sure it’s sealed tight. Paper towel method: Place a clean, dry paper towel in a container and put unwashed strawberries on top. Close the lid and place the container in the refrigerator. Rinse with vinegar solution: Soak strawberries in a vinegar solution (one-part white vinegar and three parts water) for a few minutes. Then drain them, pat them dry, and place them on a clean paper towel in a glass container. Loosely place the lid on and store in the refrigerator.

- As for the texture, they were still soft.
- So while this trick might make your berry a little brighter, there’s not much difference in the texture after sitting in water.
- It won’t hurt to give them a little more life, so go ahead and give this one a shot if your carton looks lackluster.

If they’ve got mold, they’re too far gone. We didn’t test other berries but suspect blueberries, raspberries, and blackberries would also likely benefit from this treatment. Strawberry season is right around the corner. Use these tips for making the most of your strawberry haul.
When purchasing or picking berries, they should be firm but not crunchy. Unlike apples or bananas, strawberries don’t ripen after they are harvested. Avoid bruised or shriveled berries or berries that look dull. Berries with a bright red surface will have maximum sweetness and flavor. Store strawberries in the fridge’s crisper drawer as soon as you get home and plan on consuming them within 3 to 4 days. Keep in the container they came in or a produce keeper ($23, Bed Bath & Beyond) To help berries retain flavor, texture, and nutrients, avoid washing or removing their caps until ready for use. Yes, you should always wash your fruit ! Strawberry flavor is at its best at room temperature. Remove the berries from the refrigerator an hour or two before serving.
Keep in mind that the shelf-life of your juicy berries depends on how ripe the fruit is when purchased or picked. Enjoy them asap for the best quality. If you don’t think you’ll be able to eat them before they go bad, put them to delicious use in a berry-filled sweet such as strawberry shortcakes or easy strawberry jam.
What is frost resistant strawberries?
Frost-resistant strawberries reduce the need to use chemical pesticides because a gene has already been inserted into the plant to prevent what the pesticides would fight off, such as harmful bacteria.
