Here's my distilled experience in 10 actionable strawberry gardening pointers to transform your garden into a strawberry sanctuary, regardless of its size.

Zone 3-8 Strawberry Schedule:

  • January: Secure your bare-root plants
  • Early-Mid-Spring: Plant your strawberries, 18 inches apart for June-bearing, and closer for day-neutral, as soon as the ground thaws
  • Late-Spring - Early Summer: Choose between fruit and runners, and remove the unwanted to channel plant energy
  • Late-Spring-Early Summer: Nourish your plants with their initial dose of balanced fertilizer at soil level
  • Before the first frost: Blanket your strawberries with organic straw for winter insulation
  • Spring, Post-Dormancy: Peel back the straw to warm the soil, add balanced fertilizer, and remove weeds
  • Summer: Keep bed weeded and watered, and enjoy your harvests
  • Before the first frost: Again, insulate your strawberries with organic straw against the cold

1. Select the Best Variety for Your Goals and Climate

Choose the right type based on your goals - here’s how:

June-bearing, ever-bearing, and day-neutral—each type of strawberry has its peculiarities. The best fit for your garden depends on your climate and harvesting preferences.

June-bearing:

The hallmark of most gardens, June-bearing offers a generous, punctuated harvest in late June through early July.

This selection is the most popular among gardeners due to its perennial nature and hefty harvest hauls.

In my 1-acre garden, June-bearing strawberries deliver an early burst of excitement in the growing season. Then, I can pivot to focus on other crops as the strawberry season waxes.

Pros:

  • Predictable harvest time lets your focus shift as summer matures
  • Perennial nature with self-propagation

Cons:

  • Don't expect fresh strawberries beyond late July

Top Picks for June-bearing Strawberries:

  • Pacific Northwest Jewel - Hood Strawberry: Best in Zones 6-10, avoid areas with severe winters. A tried-and-true variety that excels in jams and as a fresh snack. Offers some disease resistance (Burnt Ridge Nursery).
  • Clay-Busting Champion - Shuksan: Thrives in Zones 6-9, perfect for gardens without acidic soil or superior drainage. Exceptionally winter-hardy and disease-resistant (Burnt Ridge Nursery).
  • Unique Flavor - Northeaster: Zones 4-8, Cornell University notes these berries may hint at grape-like undertones—an interesting twist for your palate.
  • All-around Delight: Jewel:  This variety offers fantastic flavor and disease resistance. This is a popular choice with farmers and home gardeners alike  (UVM).
  • Frost Fighter - Totem: Resilient down to Zone 3, and boasts commendable disease resistance (Burnt Ridge Nursery).
  • Vermont’s Pride - Cavendish: A hit among growers in cooler climes, yields ample large berries with standout flavor. Called an “Old warhorse” by Vermont farmers due to its high yields and longer farvest season (UVM).

Ever-bearing:

Savor modest yet steady yields all year, with gluts in early and late summer.

A fantastic complement to June-bearing types, ever-bearing strawberries promise an early summer surplus and a fall encore.

Those above Oklahoma’s latitude—where "long day" onions flourish—will find ever-bearing varieties a steady choice.

Gardeners in the South should lean towards day-neutral or stick with June-bearing for best results (Michigan State University).

Here’s what the choice comes down to: Hungry for fresh strawberries all season? Choose ever-bearing. Keen on jam? June-bearing might be your sweet spot. Want both? Plant two varieties to cover all your bases.

Pros:

  • Fresh strawberries throughout the growing season
  • Perennial nature with self-propagation

Cons:

  • Regular fruit checks are necessary for harvesting

Top Ever-bearing Strawberry Varieties:

  • Tried-and-True - Seascape: To complement my June haul, I nurture Seascape Everbearing Strawberries, cherished for their sublime flavor and sizable berries.
  • Heatwave Hero - Albion: Zones 3-9, noted for large, succulent fruit, excellent flavor, and robust disease resistance.

Day-neutral:

The newest berry type, day-neutral strawberries promise hefty yields and more evenly spaced harvests throughout the year.

Despite their appeal, day-neutral types need to be replanted yearly, which deters me from fully embracing them.

Additionally, the hot summers here would stifle their production, as temperatures above 85 degrees Fahrenheit halt their growth.

Yet, for those blessed with cooler summers, day-neutral strawberries could be your ticket to season-long, bountiful crops.

Pros:

  • Fresh strawberries all season
  • Manageable patches due to lack of runners
  • Impressive yields

Cons:

  • Typically grown as annuals, requires yearly replanting
  • Production ceases in high heat

Recommended Day-neutral Varieties:

  • Tristar
  • Tribute

advises that a 5-foot row typically yields one quart of strawberries. They suggest planting approximately 125 plants to keep a family of four berry-happy.

2. When to Plant Strawberries: Key Timing Schedule for Gardeners

Plant Procurement Period

Nurseries generally ship strawberry plants in springtime. In January, stay alert for pre-order announcements from your local plant suppliers.

Per guidance from Cornell University keep your bare-root strawberries chilled in the refrigerator until it's time to plant them outside.

You can also find potted strawberries for sale in late spring, but bare-root variants are a more cost-effective option with greater numbers for your dollar.

In warmer zones, like 9 and up, fall could also be when you plant your berry plants out.

The Perfect Time to Plant

If you’re in zone 8 and lower, early spring is the planting prime time. This schedule ensures your strawberries establish well and promises a fruitful harvest.

→ Planting Primer: The crown should be above the ground, with roots fanned out below. Space your plants about 18 inches apart, with ample room for runner development.

3. Pruning: The Art of Sacrifice for Greater Rewards

In the world of June-bearing strawberries, sometimes you must surrender the immediate gratification of fruit for the long-term vitality of your patch.

Cornell University suggests a strategic choice between two pruning paths:

  • Remove blooms: Opt for a runner's reign by removing all first-year flowers, forgoing fruit to bolster plant establishment. Patience here is key—with strong roots, the coming season will shower you in berries.
  • Remove runners: If your heart is set on enjoying fruit in the inaugural year, keep runners in check to concentrate your plants' vigor.

Each method directs your plants' energies to your desired outcome, ensuring your strawberry investment flourishes.

4. Optimal Watering Practices for Vigorous Growth

Drip irrigation reigns supreme in strawberry care. This directs water to roots to spare leaves from moisture that can beckon disease.

Your strawberries will communicate their thirst—wilt signals a cry for water, while excessive moisture invites fungal foes.

Fruiting season will mean your plants need more water. After all, the lusciousness of strawberries springs from their water content, and careful watering during fruit set is crucial for the best tasting berries.

For best results, keep the straw in strawberry—straw mulch is a boon for moisture conservation and soil temperature regulation. This will reduce the frequency of your watering needs.

→ Site Selection: Sunshine and Success: Full sun is best for strawberries. Seek out a spot that receives at least six hours of daily sun; those with extra sun will often yield the most bountiful harvest.

5. Fertilizer Frequency: Feeding Your Berries Right

Nutritional Know-How: Balanced organic fertilizer applications will provide a season of vigorous growth.

Here's an organic feeding schedule to bookmark:

  1. Spring: As your plants wake from winter's slumber, welcome them with balanced nourishment.
  2. May-June : 1-2 applications of balanced fertilizer will be supportive for plants
  3. Autumn: A final balanced meal preps your plants for their winter respite.

→ Field Tip: When the fruit comes on, apply pelletized organic fertilizer to enrich the soil at the base. Stay clear of the berries to avoid tainting your harvest.

Blend in compost or seasoned manure for an added surge of organic vitality.

6. How to Manage Runners

Cultivate Continuity with Runners: After the harvest, nominate the strongest runners to colonize new soil plots. This means you can have productive plants for eternity.

Eventually, older plants will wane. Introduce fresh runners to replace the weary to infuse new life into your patch.

Some yearn for orderly rows, but letting runners grow free can smother weeds and multiply your harvest without extra effort.

7. The Importance of Pollination for Abundant Harvests

Adequate pollination is the keystone of well-formed strawberries. If row covers are your shield against hungry deer and rabbits, remember to peel covers back during the day to let pollinators court your blooms.

Lure beneficial bees with flowers that bloom in harmony with your strawberry blossoms.

Strategically spaced plants aren't just aesthetically pleasing—they're a canvas for pollinators to paint their masterpiece.

8. Weeding Strawberries: An essential task

Stay vigilant with weeds, especially when runners are in play. Larger weeds, when uprooted, can damage your plants.

In my patch, the autumn is prime time for weed insurgencies. A focused effort then, followed by a secondary winter clearance, secures a season of serenity.

A robust application of straw mulch not only braces against the cold but also helps prevent weed invasion.

In a popular permaculture forum, folks suggest interplanting asparagus with strawberries to help keep weeds down. Since asparagus take several years to establish, this is a great way to still have their area be productive while you’re waiting for them to mature.

9. Keep Pests away from your Yield

Row covers can deter birds, deer, and insects from harvesting your strawberries for you. I drape our strawberries in a mesh row cover right when they first set bloom. The edges of the mesh row cover are secured with bricks, so no critters can come into the patch.

Row covers are one of the biggest keys to our patch’s success - if you take any advice from this article, let it be row covers!

10. Prepare your Patch for Winter

A Straw Blanket for Berry Dreams: In the chill of colder climates, a thick layer of straw mulch supports your plants against winter's chill.

Come spring, remove the mulch so that the soil can warm up. Then remulch as the temperature increases in the summer heat.

Now you're on your way to a pantry shelf lined with homemade strawberry jam

With these fine-tuned tips and tender care, your strawberry patch will blossom into a cornucopia of sweetness. Watch and adapt, for each plant and climate carves its unique path. Embrace this guide as your compass, and soon, you'll be the artisan of an edible Eden.
