Iowa’s rich prairie soils and consistent rainfall provide excellent conditions for growing vigorous June-bearing strawberry plants. If you’re looking for the best strawberries to grow in iowa, you need varieties that handle cold winters and humid summers well. Strawberries thrive here when you pick the right types for your garden.
Growing your own strawberries means sweet, fresh fruit right from your backyard. You avoid store-bought berries that traveled thousands of miles. Plus, homegrown strawberries taste way better than anything from a supermarket.
Let me walk you through the top strawberry varieties for Iowa gardens. I’ll cover what grows best, when to plant, and how to care for your plants. This guide makes it simple to choose and succeed.
Best Strawberries To Grow In Iowa
Iowa’s climate suits three main strawberry types: June-bearing, everbearing, and day-neutral. Each has pros and cons for your garden. June-bearing varieties produce one large crop in late spring or early summer. They give you the biggest harvest at once, perfect for making jam or freezing.
Everbearing strawberries produce two to three crops per season. You get berries in spring, summer, and fall. Day-neutral varieties keep producing fruit all season long as long as temperatures stay between 40 and 85 degrees Fahrenheit.
For most Iowa gardeners, June-bearing strawberries work best. They handle winter cold better and produce larger yields. But everbearing and day-neutral types can extend your harvest season significantly.

How To Plant Strawberries In Iowa
Planting strawberries correctly sets you up for success. Iowa’s climate requires specific timing and techniques. Follow these steps for a healthy, productive strawberry patch.
Choose The Right Location
Strawberries need full sun for best production. Pick a spot that gets at least 6 to 8 hours of direct sunlight daily. The soil should drain well. Avoid low areas where water pools after rain. Strawberries rot easily in wet soil.
Test your soil pH before planting. Strawberries prefer slightly acidic soil with a pH between 5.5 and 6.5. Iowa soils often have higher pH, so you may need to add sulfur or peat moss to lower it.
Prepare The Soil
Prepare your strawberry bed in fall for spring planting. Remove all weeds and grass. Till the soil to a depth of 8 to 10 inches. Mix in 2 to 3 inches of compost or well-rotted manure. Add a balanced fertilizer like 10-10-10 according to package directions.
If you’re planting in spring, prepare the bed as soon as the soil can be worked. Iowa’s spring weather can be unpredictable, so wait until the soil is dry enough to crumble in your hand.
Planting Time
Plant strawberries in early spring as soon as the soil is workable. In southern Iowa, this is usually mid-March to early April. In northern Iowa, wait until late March to mid-April. You can also plant in late summer or early fall, but spring planting gives better results.
Space plants 12 to 18 inches apart in rows 3 to 4 feet apart. Dig a hole deep enough to cover the roots completely. The crown (where leaves meet roots) should sit at soil level. Covering the crown too deep causes rot. Leaving it too high dries out the roots.
Watering After Planting
Water your new strawberry plants thoroughly after planting. Keep the soil consistently moist for the first few weeks. Strawberries need about 1 to 1.5 inches of water per week during the growing season. Drip irrigation works best because it keeps leaves dry and reduces disease.
Caring For Your Strawberry Plants
Strawberries need regular care to produce well. Follow these tips for healthy plants and big harvests.
Mulching
Mulch helps strawberries in several ways. It keeps soil moist, suppresses weeds, and protects berries from dirt. Use straw, pine needles, or shredded leaves. Apply a 2 to 3 inch layer around plants after planting.
In winter, mulch protects plants from freezing and thawing cycles. Apply 4 to 6 inches of straw or hay after the ground freezes in late fall. Remove most of the mulch in early spring when new growth appears.
Fertilizing
Fertilize strawberries in early spring when new growth starts. Use a balanced fertilizer like 10-10-10 at a rate of 1 pound per 100 square feet. Avoid high-nitrogen fertilizers because they promote leaf growth at the expense of fruit.
For June-bearing varieties, fertilize again after harvest. This helps plants produce strong runners for next year’s crop. Everbearing and day-neutral varieties benefit from light monthly fertilizing during the growing season.
Watering
Strawberries need consistent moisture, especially during fruiting. Water deeply once or twice a week rather than shallow daily watering. Aim for 1 to 1.5 inches of water per week including rainfall. Use soaker hoses or drip irrigation to keep leaves dry.
During hot, dry spells, increase watering. Strawberries stressed by drought produce small, tough berries. Mulch helps retain soil moisture and reduces watering frequency.
Weed Control
Weeds compete with strawberries for water and nutrients. Keep your strawberry patch weed-free. Hand pull weeds regularly, being careful not to disturb strawberry roots. Mulch helps suppress weeds significantly.
You can use pre-emergent herbicides labeled for strawberries, but hand weeding is safer for home gardens. Avoid using herbicides near your strawberry plants unless you’re certain they’re safe.
Renovating June-Bearing Strawberries
Renovate June-bearing strawberry beds after harvest each year. This process keeps plants productive for 3 to 4 years. Mow or cut leaves about 1 inch above the crowns. Thin plants to 4 to 6 inches apart within rows. Remove excess runners and weeds.
After renovating, fertilize with 1 pound of 10-10-10 per 100 square feet. Water well to encourage new growth. This prepares plants for next year’s crop.
Common Strawberry Problems In Iowa
Iowa’s climate creates some challenges for strawberry growers. Here are common problems and how to handle them.
Diseases
Gray mold (Botrytis) is common in wet weather. It causes berries to rot on the plant. Improve air circulation by spacing plants properly. Remove infected berries immediately. Fungicides can help if applied early.
Leaf spot and leaf scorch cause brown spots on leaves. These diseases rarely kill plants but reduce vigor. Remove infected leaves and avoid overhead watering. Resistant varieties like Allstar and Honeoye help prevent these issues.
Red stele root rot is serious in poorly drained soil. It causes plants to wilt and die. Plant in well-drained soil and choose resistant varieties. Once present, red stele is hard to eliminate.
Pests
Spider mites cause leaves to turn yellow and stippled. They thrive in hot, dry weather. Spray plants with water to knock them off. Insecticidal soap works well for severe infestations.
Slugs and snails eat holes in ripe berries. They’re active at night and in wet weather. Remove mulch around plants during fruiting. Set out beer traps or use slug bait labeled for gardens.
Birds love strawberries as much as you do. Cover plants with bird netting when berries start to ripen. Scare devices work temporarily but birds get used to them quickly.
Winter Damage
Iowa winters can kill unprotected strawberry plants. The main danger is freezing and thawing cycles that heave plants out of the ground. Mulch heavily after the ground freezes. Remove mulch gradually in spring to protect new growth from late frosts.
Choose winter-hardy varieties like Honeoye and Jewel. These handle Iowa’s cold better than less hardy types. Avoid planting in low spots where cold air settles.
Harvesting And Storing Strawberries
Harvest strawberries when they’re fully red. Pick in the morning when berries are cool. Hold the stem just above the berry and twist gently. Don’t pull the berry itself because it bruises easily.
Harvest every 2 to 3 days during peak season. Berries left on the plant too long rot or get eaten by pests. Check plants daily once berries start turning red.
Store unwashed strawberries in the refrigerator. They last 3 to 5 days when stored properly. Wash berries just before eating to prevent mold. For longer storage, freeze strawberries whole or sliced on a baking sheet, then transfer to freezer bags.
Frequently Asked Questions
What Is The Best Time To Plant Strawberries In Iowa?
Early spring is the best time, as soon as the soil can be worked. In southern Iowa, this is mid-March to early April. In northern Iowa, wait until late March to mid-April. Fall planting is possible but less reliable due to winter kill.
Can I Grow Strawberries In Containers In Iowa?
Yes, strawberries grow well in containers. Use pots at least 12 inches deep with drainage holes. Fill with quality potting mix. Place containers in full sun. Water more frequently than in-ground plants because containers dry out faster. Bring containers to a protected area during severe winter cold.
How Long Do Strawberry Plants Live In Iowa?
Strawberry plants produce well for 3 to 4 years. After that, production declines. June-bearing varieties need renovation each year to stay productive. Replace your strawberry patch every 3 to 4 years for best results. Plant new beds in a different location to avoid soil-borne diseases.
Do I Need To Protect Strawberries From Frost In Spring?
Yes, late spring frosts can damage flowers and young fruit. Cover plants with row covers or old sheets when frost is forecast. Remove covers during the day so bees can pollinate flowers. Floating row covers provide several degrees of frost protection.
