Best Time to Sow in India

Critical Timing: Lupins need cool weather for germination and growth but cannot handle extreme heat during flowering.

North India:

• Plains: October to November (blooms February-March)

• Hills: March to April (blooms June-July)

South India:

• October to November (blooms January-February)

• Hill stations: Year-round in moderate climates

West & Central India:

• November to December (blooms February-March)

Pro Tip: Sow so plants flower before temperatures exceed 30°C consistently.

Seed Starting Master Guide

1. Essential Seed Treatment

Lupin seeds have hard coats that require scarification:

Method 1: Physical Scarification

• Gently rub seeds between sandpaper

• Or nick seed coat with nail clipper

• Be careful: Don't damage the inner embryo

Method 2: Hot Water Treatment

• Soak seeds in hot (not boiling) water for 24 hours

• Water should be about 80°C when poured over seeds

• Seeds that sink are viable

Method 3: Overnight Soaking

• Soak in room temperature water for 12-24 hours

2. Perfect Seed Starting Mix

Lupins are sensitive to damping off and need excellent drainage:

• 40% cocopeat

• 30% vermicompost

• 20% perlite

• 10% fine sand

• Pinch of trichoderma powder (prevents fungal issues)

3. Sowing Technique

Individual Pots Recommended (they hate root disturbance):

1. Fill 3-inch pots with prepared mix

2. Sow 2 seeds per pot ¼ inch deep

3. Water gently with spray bottle

4. Cover with clear plastic for humidity

5. Keep at 15-20°C for germination

Germination Details:

• ✅ Time: 14-30 days (be patient!)

• ✅ Temperature: 15-20°C ideal

• ✅ Light: Bright indirect light

• ✅ Success Rate: 60-70% with proper treatment

---

Critical Seedling Care

Post-Germination (Weeks 1-4):

• Remove weakest seedling from each pot

• Provide morning sun gradually

• Keep soil moist but not waterlogged

• Good air circulation to prevent damping off

When to Transplant:

• Wait for 4-6 true leaves

• Height: 3-4 inches tall

• Critical: Minimize root disturbance

• Best to transplant from pots without breaking root ball

---

Transplanting to Final Location

Soil Preparation is Crucial:

Lupins need slightly acidic to neutral, well-draining soil:

Ideal Soil Mix:

• 40% garden soil

• 30% compost

• 20% cocopeat

• 10% sand

• Additives:

  • 1 tablespoon sulfur per plant (for acidity)

  • Handful of bone meal

  • 1 tablespoon neem cake

Spacing Guidelines:

• Tall varieties: 18-24 inches apart

• Dwarf varieties: 12-15 inches apart

• Container growing: 1 plant per 12-inch pot

---

Growing Conditions for Success

Sunlight Requirements:

• Full sun: 6-8 hours in cool weather

• Partial shade: Afternoon shade in warmer regions

• Hill stations: Full sun acceptable

Temperature Preferences:

• Germination: 15-20°C

• Growth: 10-25°C

• Flowering: 15-22°C ideal

• Above 30°C: Plants decline rapidly

Watering Wisdom:

• Consistent moisture during growth

• Avoid overhead watering - causes fungal issues

• Deep watering 2-3 times weekly

• Reduce watering when temperatures rise

---

Feeding for Fabulous Flowers

Fertilizer Strategy:

Lupins fix their own nitrogen, so focus on other nutrients:

Monthly Feeding:

• Liquid seaweed solution

• Phosphorus-rich fertilizer (NPK 5-15-5)

• Epsom salt for magnesium (1 tsp/gallon)

Avoid:

• High nitrogen fertilizers

• Fresh manure

• Chemical-heavy feeds

Soil pH Management:

• Ideal pH: 6.0-7.0

• Test soil before planting

• Add sulfur if soil is too alkaline

• Add lime if too acidic (rare in India)

---

Seasonal Care Schedule

October-November (Sowing):

• Treat and sow seeds

• Maintain cool germination conditions

December-January (Growth):

• Transplant seedlings

• Provide morning sun

• Begin light feeding

February-March (Flowering):

• Peak bloom period

• Regular deadheading

• Protect from rising temperatures

April-Onwards (Decline):

• Plants naturally decline in heat

Troubleshooting Common Problems

---

Propagation Methods

Seed Propagation (as above):

• Collect seeds when pods turn brown

• Store in cool, dry place

• Viability: 2-3 years

Division (Limited Success):

• Divide established plants in early spring

• Replant immediately

• Water well after division

Basal Cuttings:

• Take cuttings from base of plant in spring

• Root in sand + cocopeat mix

• Moderate success rate

Special Tips for Indian Conditions

1. Choose Early-Flowering Varieties to beat the heat

2. Morning Sun Only in warm regions

3. Raised Beds for better drainage

4. Mulch Heavily to keep roots cool

5. Grow as Annuals in most Indian plains

6. Container Growing allows moving plants to cooler spots

Companion Planting Ideas

Perfect Partners:

• Spring bulbs - tulips, daffodils

• Other cool-season flowers - snapdragons, stock

• Ornamental grasses - for contrast

• Silver foliage plants - artemisia, dusty miller
