When to Plant Strawberries in NZ: Timing, Care & More

There’s something special about picking your own strawberries from the garden, especially when you’ve timed the planting just right. In New Zealand, the ideal window runs from June to November, but getting the best harvest means matching your planting to your local climate zone. Whether you’re on a Northland lifestyle block or a Southland backyard, this guide covers timing, companion plants, and seasonal care to help you succeed.

Planting window in NZ: June to November · Ideal temperature: 15–25°C · Sunlight needed: 6–8 hours daily · Time to harvest: 60–90 days after planting

Five key facts every NZ strawberry grower should know, from soil requirements to spacing.

When should you plant strawberries in New Zealand?

When to plant strawberries in Auckland?

• Auckland sits in a warm northern region, so plant from June to September (The Kiwi Country Girl).
• Mitre 10 recommends June to October for northern areas (Mitre 10 Easy As Garden).
• Avoid late spring planting when soil warms up – earlier gives stronger crowns.

When to plant strawberries in winter?

• Winter planting is possible in warmer regions if you protect plants with cloches or raised beds (Palmers garden centre).
• For most of NZ, the classic window is late winter to early spring (July–September).
• In cooler areas like Southland, wait until August–September.

When to plant strawberries in pots?

• Same timing applies: June–November, with early spring (August–October) considered best (Kings Plant Barn).
• Pots warm up faster than ground, so you can plant a few weeks earlier in sheltered spots.

Planting steps:

1. Choose a sunny, sheltered spot – strawberries need at least 6–8 hours of sun (Bonnie Plants).
2. Prepare soil: slightly acidic (pH 5.5–6.5), rich in organic matter (Palmers).
3. Space plants 30 cm apart, rows 40 cm apart.
4. Plant so the crown sits just above the soil line (Palmers).
5. Water well after planting and mulch to retain moisture.

The pattern: In New Zealand, strawberry planting is not a one-size-fits-all date — your location and local microclimate determine the ideal window. Failure to match timing to your region can leave plants struggling through frost or missing the summer heat for ripening.

Do strawberry plants do better in pots or ground?

Three key differences between container and in-ground growing, with trade-offs for each.

The trade-off: For most home gardeners, a mix of both works best — a few pots for mobility and a ground patch for larger harvests, as long as you rotate the ground bed every three years.

What should you not plant strawberries next to?

Plants to avoid near strawberries

• Avoid members of the Solanaceae family: tomatoes, peppers, potatoes, eggplants – they share soil-borne diseases (Gardenia.net).
• Keep brassicas (cabbage, broccoli, kale) away – they compete for nutrients.
• Garlic can inhibit strawberry growth; use onions or chives instead (Gardenia.net).

Best companion plants for strawberries

• Borage attracts bees and improves flavour (Gardenia.net).
• Lettuce and spinach act as living mulch, shading soil and suppressing weeds (Gardenia.net).
• Thyme and chives help deter pests.
• Alyssum, calendula, and scabiosa attract pollinators (Gardenia.net).

Why this matters: A well-planned companion planting scheme reduces the need for chemical sprays and can boost yields by improving pollination and soil health.

What does Epsom salt do for strawberries?

Benefits of Epsom salt (magnesium and sulfur)

• Magnesium supports chlorophyll production and fruit development. Some gardeners apply Epsom salt as a supplement, though results are anecdotal.
• Bonnie Plants notes that strawberries prefer slightly acidic soil (pH 5.5–6.8) – Epsom salt can help maintain that balance when used sparingly (Bonnie Plants).

How to apply Epsom salt

• Mix 1 tablespoon of Epsom salt per litre of water and apply as a soil drench once a month during the growing season.
• Avoid overuse – too much can lead to salt buildup in pots.

Using coffee grounds and baking soda

• Coffee grounds add nitrogen and acidity; sprinkle lightly around plants (Palmers notes the ideal pH is 5.5–6.5, so use coffee grounds in moderation).
• Baking soda diluted as a spray (1 teaspoon per litre of water) is sometimes used as a DIY fungicide, but controlled studies are lacking.

The implication: Soil amendments can help, but they’re not a substitute for proper planting time and site selection. Treat them as fine-tuning, not a magic fix.

What do I do with strawberry plants in autumn?

End of season care in NZ

• After the last harvest (usually late January to March), cut back old foliage to 5 cm above the crown (Daltons).
• Mulch around crowns with straw or pine needles for winter protection.
• Remove any diseased leaves to prevent overwintering pathogens.

Transplanting strawberries in October

• October is spring in NZ – it’s a good time to transplant established runners to a new bed.
• Water well before moving, and replant with the crown just above soil level.
• October planting is also ideal for late-blooming regions like Canterbury.

Dividing strawberry plants

• Divide plants in early spring (August–September) or right after fruiting (January–February).
• Choose vigorous crowns from 1–2 year old plants.
• Replant divisions at the same depth and water generously.

“We do however recommend when planting to get them into the soil early in the morning or late in the day.”

— Palmers garden centre

“Any time from June-September for warmer climates and August/September for cooler climates.”

— The Kiwi Country Girl

“Strawberries are best planted from June to November, with early spring from late August to October highlighted as the best time.”

— Kings Plant Barn

Every region in New Zealand has its sweet spot. For Auckland gardeners, the window is June to September; for Southland, August to September. The key is to match your planting to your local microclimate – and to act early, because strawberries that go in on time produce consistently longer harvests. For gardeners in cooler areas, skipping the winter rush and waiting until early spring gives plants a stronger start. The choice is clear: plant in the window that fits your zone, or face a disappointing summer.
