Getting Started Methods
1. Seed Starting (Most Economical)
- 1
Timing
Start indoors 4-6 weeks before last frost. March-April is ideal. - 2
Container Preparation
Fill seed trays or small pots with seed starting mix. Moisten. - 3
Seed Sowing
Sprinkle seeds on surface, cover lightly with 0.5 cm soil. Don't press. - 4
Light Requirement
Basil seeds need light to germinate. Don't bury deep. - 5
Waiting
Keep in warm (20-25C) and bright location. Germinates in 5-10 days. - 6
Thinning
If germination is too dense, thin by keeping the strongest seedlings.
2. Buying Seedlings (Fastest)
Advantages of buying ready basil from stores or nurseries:
- Immediate harvest
- Guaranteed success
- Time savings
Warning
Store-bought basil pots usually have too many plants. Divide and transplant to separate containers when you get home - otherwise they'll weaken from competition.
3. Cutting Propagation (Most Practical)
You can produce unlimited new plants from an existing basil:
- 1
Cut the Stem
Cut a 10-15 cm long stem without flowers. - 2
Remove Lower Leaves
Remove leaves from the bottom 5 cm. - 3
Place in Water
Put in a clear glass, keep leaves above water. - 4
Wait
Roots appear in 1-2 weeks. Plant in soil when roots are 3-5 cm long.
Container and Soil
Container Selection
| Feature | Ideal |
|---|---|
| Minimum diameter | 15 cm (single plant) |
| Ideal diameter | 20-25 cm |
| Depth | At least 15 cm |
| Drainage | Must have holes |
| Material | Ceramic or plastic |

Soil Mix
Basil loves well-draining, nutrient-rich soil:
- Ready potting soil: 70%
- Perlite: 20% (for drainage)
- Compost: 10% (for nutrients)
Garden Tip
Don't use garden soil! It's too heavy, may carry diseases, and compacts in containers.
Ideal Conditions
Light
| Condition | Result |
|---|---|
| 6-8 hours sun | Ideal, lush growth |
| 4-6 hours sun | Acceptable, slow growth |
| Under 4 hours | Insufficient, tall and weak growth |
Direction preference: Southwest or southeast balconies give best results.
Temperature
| Temperature | Effect |
|---|---|
| 20-30C | Ideal growth |
| 15-20C | Slow growth |
| Below 10C | Growth stops |
| Frost | Plant dies |
Fall Tip
When night temperatures start dropping below 10C, bring basil indoors or harvest it.
Care
Watering
Basil loves moisture but hates standing water:
- Finger test: Water when soil surface dries
- Summer: Once daily (morning)
- Spring/Fall: Every 2-3 days
- Base watering: Avoid water on leaves
Warning
Avoid evening watering! Leaves staying damp overnight invite fungal diseases.
Fertilizing
| Period | Fertilizer | Frequency |
|---|---|---|
| Early growth | Balanced liquid fertilizer | Every 2 weeks |
| Full growth | Nitrogen-heavy | Every 10 days |
| Before flowering | Reduce | - |
Garden Tip
If harvesting leaves, nitrogen is important. If allowing flowering, reduce fertilizing.
Pruning and Harvesting
This is the most critical part of basil care! Regular pruning:
- Increases branching
- Delays flowering
- More leaves = more harvest
- 1
Tip Pinching
When plant is 15-20 cm tall, pinch off the top shoot. This triggers branching. - 2
Regular Harvesting
Regularly pick the top 2-3 leaf pairs from each stem. - 3
Cutting Point
Always cut just above a leaf pair. - 4
Remove Flower Buds
Pinch off flower buds as soon as you see them. Flowering reduces leaf quality.
Common Problems
Tall and Weak Growth
Cause: Insufficient light Solution: Move to sunnier location, do tip pinching
Yellowing
Cause: Overwatering or nutrient deficiency Solution: Check watering frequency, light fertilizing
Brown Spots on Leaves
Cause: Sunburn or fungus Solution: Protect from midday sun, ensure air circulation
Aphids
Symptom: Sticky leaves, small insects Solution:
- Wash off with strong water spray
- Soapy water spray (1 tbsp liquid soap per liter of water)
- Neem oil
Bolting (Flowering)
Cause: Temperature stress, long days Result: Leaves become bitter Prevention: Regular harvest, pinch off flower buds
Harvest and Storage
Harvest Time
- Early morning (oils most concentrated)
- Before flowering (best flavor)
- Regularly (encourages branching)
Fresh Storage
| Method | Duration |
|---|---|
| In water (like a vase) | 1-2 weeks |
| Wrapped in paper towel (refrigerator) | 1 week |
| Plastic bag (refrigerator) | 3-5 days |
Garden Tip
Don't refrigerate basil! Cold darkens the leaves. It keeps best at room temperature in water.
Long-term Storage
Freezing
- Wash and dry leaves
- Place in ice cube trays
- Cover with olive oil
- Freeze
Drying
- Hang dry in shade, airy location
- Dehydrator (35C)
- Crumble and store in jars
Making Pesto
If you have abundant basil, make pesto and freeze!
Basic Pesto:
- 2 cups fresh basil
- 1/2 cup parmesan
- 1/3 cup pine nuts
- 2 garlic cloves
- 1/2 cup olive oil
- Salt, pepper
Seasonal Calendar
Spring Tip
March-April: Seed starting or seedling purchase. Balcony season begins!
Summer Tip
May-August: Full growth and harvest period. Regular pruning and watering are critical.
Fall Tip
September-October: Growth slows. Harvest abundantly, make pesto, freezing time.
Winter Tip
November-February: Won't survive outdoors. Continue by window with grow light.
Basil and Companion Plants
Good Neighbors
- Tomatoes: Improves flavor, deters pests
- Peppers: Similar requirements
- Oregano: Together for pesto!

Indoor Growing (Winter)
For fresh basil during winter months:
Requirements
- Grow light: 12-14 hours daily
- Temperature: 18-24C (not near radiator)
- Humidity: Increase with spraying
Conclusion
Basil is a perfect plant to start balcony gardening. It grows fast, yields abundant harvests, and is used in every dish. The secret to success: plenty of sun, regular watering, and harvesting before flowering.
3 golden rules:
