🌱 Starting Ivy Geraniums from Seed

Growing Ivy Geraniums from seed is simple and rewarding — and it starts with one little nursery secret.

The Fridge Trick for Better Germination

Before sowing, wrap the seeds in a slightly moist paper towel, seal in a bag, and refrigerate for 24 hours. This cold-moist conditioning helps synchronize germination and produces stronger seedlings.

Germination Conditions:

  • Temperature: 73°F (23°C)

  • Light: Not required for germination

  • Media: Fine, sterile mix with good drainage

  • Moisture: Level 5 (saturated) until sprouting

  • Time: ~4 days to germinate

Once sprouted, move seedlings to bright light and maintain media pH at 5.8–6.2. Feed lightly at 75–125 ppm N.

🌞 Growing & Care Tips for Healthy Plants

Light: Ivy Geraniums are irradiance plants — they bloom faster and stronger with high light. Aim for 12–14 mols/day DLI or supplement under cloudy conditions.

Temperature:

  • Day: 68–72°F

  • Night: 60–62°F

Fertilizer: 125–175 ppm N, balanced formula
Moisture: Alternate between level 2 (medium) and 4 (wet). Avoid keeping soil constantly wet.
Transplanting: Move to finished pots once seedlings have 3–5 true leaves.

When growing for hanging baskets, plant:

  • 4” pots: 1 plant per pot (8–9 weeks)

  • 10” baskets: 3–5 plants per basket (10–11 weeks)

  • 12” baskets: 5–6 plants per basket (10–12 weeks)

💧 Troubleshooting Common Ivy Geranium Problems

Even healthy geraniums can show signs of stress. Here are the most common issues — and how to fix them:

🟡 Yellow Leaves:

  • Caused by low pH (<5.8) or overwatering.

  • Keep soil slightly dry and feed at 125–175 ppm N.

🌿 Weak or Stretched Growth:

  • Caused by low light or excessive warmth.

  • Provide bright light (12–14 mols/day) and cooler nights.

🌺 Poor Flowering:

  • Caused by too little light or high nitrogen.

  • Reduce fertilizer slightly and move to full sun.

🌱 Root Rot or Wilt:

  • Avoid saturated soil and recycled irrigation water.

  • Use clean trays, media, and strong airflow.
