☀️ Light - the more, the better!
Light requirement: Tagetes is a plant that loves full sun - at least 6-8 hours a day!
Full sun (6+ hours)
Full shade (poor flowering)
What happens in the absence of light?
- Poor flowering: fewer flowers or none at all
- "Reglony" plant: long, weak stems
- Disease susceptibility: May suffer from mold
💧 Irrigation - balanced and correct
Key principle: Tagetes prefers soil that dries out slightly between waterings - not too wet, not too dry !
Watering frequency:
- In the garden: once a week (thorough watering)
- In a pot: every day or two in the summer
- Rule: When the soil is dry to a depth of 2-3 cm
Irrigation method:
- Water at the base of the plant , not on the leaves!
- Wetting leaves causes fungal diseases
- Deep and extensive watering is better than shallow and frequent.
🪴 Soil and pot
Soil type:
Drains well - most important!
- ✅ Mixed sandy or clay soil
- ✅ pH 6-7 (slight to neutral acidity)
- ✅ Soil rich in organic matter
- ❌ Heavy, water-retaining soil
Soil preparation:
- Dig to a depth of 15-20 cm.
- Mix in compost or humus
- Add perlite to improve drainage.
Planting intervals:
- French tagetes: 20-25 cm
- American Tagetes: 25-30 cm
- Large varieties: 45-60 cm
🌡️ Temperature
Ideal range: 18-28°C - but also tolerates Israeli heat!
- ✅ Loves heat - thrives in summer
- ✅ Tolerates up to 35°C+ in full sun
- ❄️ Frost sensitive - dies in freezing temperatures
- 📅 Plant after the last frost (March-April)
🌱 Planting and growing from seeds
Tagetes is very easy to grow from seed - one of the simplest plants to start with!

🧪 Fertilization
Tagetes doesn't require much fertilizer - in fact, over-fertilizing will result in leaves at the expense of flowers!
Fertilization recommendations:
- In the garden: adding compost before planting is usually sufficient
- In a pot: Balanced liquid fertilizer once a month
- Fertilizer type: High potassium fertilizer (for flowering)
- Avoid: Nitrogen-rich fertilizers (will cause leaves instead of flowers)
✂️ Pruning and maintenance
Thinning Flowers (Deadheading) - A Must!
Removing wilted flowers is the secret to continued flowering :
- ✂️ Remove flowers that have started to wilt.
- 🌸 This encourages the formation of new flowers
- 📅 Do this regularly throughout the season
- 💪 The plant will bloom until the first frost!
Pinching
For denser, more lush plants:
- Pinch the young head when it has 4-6 leaves.
- This will cause splitting and more branches.
- More branches = more flowers!
Seed collection
Want to save seeds for next year?
- Leave some flowers to sow at the end of the season.
- Wait until the flower is completely dry.
- Collect the long, black seeds.
- Store in a cool, dry place.
