Isolated Blossom-End Rot and Sunflower Germination Secrets

When only 1 of 8 tomato plants shows blossom-end rot, the cause is plant-specific, not systemic.

Single-Plant Blossom-End Rot

Likely causes: Root damage during transplant, slightly different microclimate (more sun/wind), or genetic variation in calcium efficiency.

Quick fix: Foliar spray 1 tbsp Epsom salts + 1 tsp calcium nitrate per gallon every 7–10 days. Mulch heavily. It typically resolves as roots expand.

Sunflower Germination Failures

Common culprits:

• Bird/vole predation: Seeds eaten before emergence.
• Planting too deep: 1 inch max; they need light to germinate.
• Cold, wet soil: Rots seeds. Wait for 60°F+ soil.
• Hard seed coat: Nick with sandpaper or soak 4–6 hours.

Proven Indoor-Start Method

1. Start in peat pots mid-April (3–4 weeks before last frost).
2. 1 seed per pot, ½ inch deep.
3. Bottom heat (70°F) speeds germination.
4. Transplant at 3 true leaves—plant entire peat pot to avoid root disturbance.
5. Harden off 7–10 days before planting out.

This bypasses nearly all field germination issues.
