Strawberries – those juicy, sweet, and slightly tart berries – are a beloved treat for many. But did you know that growing strawberries in Northern Vietnam can be quite challenging? The region’s climate differs significantly from the strawberry’s ideal growing conditions, making many hesitant to try.
Don’t worry! This article will share the secrets to successful strawberry cultivation in Northern Vietnam, from A to Z, empowering you to harvest delicious, ripe strawberries right at home.
Preparing for Strawberry Cultivation in Northern Vietnam
1. The Ideal Planting Time in Northern Vietnam
October and November are the optimal months for planting strawberries in Northern Vietnam. During this period, the cool weather and high humidity create favorable conditions for the seedlings to take root and thrive. With just 2-3 months of care, you can harvest your first batch of strawberries.
2. Selecting the Right Strawberry Variety for Northern Vietnam’s Climate
Growing strawberries from seeds or seedlings is possible, but seedlings will save you time and effort. Choose healthy, pest-free seedlings, about 10-15cm tall.
Here are some strawberry varieties well-suited to the Northern Vietnamese climate:
- Everbearing Strawberries: Produce two crops per year, from spring to late summer or fall.
- June-bearing Strawberries: Fruit mainly in June, require ample space, and are not suitable for pot cultivation.
- Day-Neutral Strawberries: Produce continuously from summer to late fall, tolerate low temperatures (1-3°C).
- Hana Strawberries: A newer variety, high-yielding, juicy, and heat-tolerant.
3. Choosing the Right Pot for Strawberry Planting
Clay or plastic pots are suitable, as long as they have drainage holes. Pots with a diameter of about 20cm are ideal, allowing for healthy growth without frequent repotting.
4. Soil: The Key to Bountiful Strawberry Harvests
Strawberries require light, well-drained, nutrient-rich soil that retains moisture well. You can create your own mix using clean soil, coconut coir, rice husk charcoal, and organic compost in a 5:2:2:1 ratio.
Tip: Use Sfarm organic soil – a pre-treated, pathogen-free product blended with the right proportion of vermicast, saving you time and effort.
5. Planting Location: Well-Ventilated and Sunny
Strawberries need a well-ventilated and sunny location for photosynthesis and growth. The ideal temperature range is 7-30°C.
Balconies, windowsills, and terraces are ideal locations for growing strawberries. Ensure the plants receive sufficient sunlight, but not more than 12 hours per day, and avoid artificial light at night.
How to Plant Strawberries in Northern Vietnam
1. Planting Strawberries from Seeds
- Seed Germination: Soak the seeds in warm water (45-60°C) for about 6 hours. Remove and spread evenly on a plate lined with a damp cloth, covering with another damp cloth. Once the seeds sprout, air dry them for 30 minutes before sowing.
- Sowing: Sow the seeds in the prepared soil, watering twice daily to maintain moisture.
- Care: After germination, remove weak seedlings to ensure adequate spacing and nutrients for optimal growth.
2. Planting Strawberries from Seedlings
- Digging Holes: Dig small holes, about 5-7cm deep.
- Planting: Place the seedlings in the holes, gently covering with soil without compacting it.
- Watering: Water immediately after planting, gently to prevent the seedlings from falling over.
Note: Avoid planting seedlings too shallow or too deep, as this can affect root development.

Strawberry Care in Northern Vietnam: The Key to a Bumper Harvest
1. Initial Stage After Planting
- Protection: Shield the seedlings from rain and direct sunlight for the first 2-3 days.
- Sunlight: Ensure they still receive sufficient indirect sunlight for growth.
- Watering: Water regularly to keep the soil moist.
2. Pruning: Focusing Nutrients on Fruit Development
- Removing Flowers and Small Fruits: When the plant flowers and fruits, prune some flowers and small fruits to allow the plant to concentrate nutrients on the main fruits, resulting in larger, more uniform, and tastier strawberries.
- Ant Control: Ants are attracted to strawberries, so regularly check for and eliminate them.
- Fruit Positioning: Guide the strawberries towards the edge of the pot for even development and reduced pest and disease risk.
3. Runner Management: Propagation or Nutrient Focus?
Healthy strawberry plants will produce runners (new plants). You can:
- Remove Runners: If you want the plant to focus on fruit production, remove runners as soon as they appear.
- Propagate: When the runner’s roots reach about 0.5cm long, add soil for the runner to root. Once the runner develops into an independent plant, separate and transplant it into a new pot.
4. Watering: “Water is the Food of Plants”
- Water Quantity: Water each plant with 150-200ml of water, avoiding over or underwatering.
- Watering Time: Water early in the morning.
- Water Type: Use clean water. If using hydroponic solution, follow the instructions carefully.
5. Fertilizing: Replenishing Soil Nutrients
- Organic Fertilizer: Apply decomposed organic fertilizer (vermicast, chicken manure, cow manure) once a month from June to September.
- Inorganic Fertilizer: Supplement with NPK 20/20/20 fertilizer to increase yield and fruit quality. Apply 4-6 weeks after planting, in August, and after the first harvest.
- Note: Avoid fertilizing when the plant is fruiting and do not overuse fertilizers.
6. Pest and Disease Management: Maintaining a Healthy Strawberry Garden
- Yellow Leaves: Indicates a lack of water, nutrients, or sunlight.
- Overcrowding: Thin out excess seedlings and transplant them into new pots.
- Leaf Pruning: Regularly remove old, yellow, or diseased leaves.
- Pests and Diseases: Inspect regularly and eliminate insects and diseases as soon as they appear.
- Black Spot Disease: Remove affected leaves and apply fungicide (following the instructions carefully).
Note: Do not spray pesticides when the fruits are ripening.
