Planting Instructions:

• - Transplant during any frost-free period when temperatures remain above 45°F

Soil Preparation:

• - Ideal soil pH: 6.0-7.0

Watering Specifics:

• - Water consistently, keeping soil moist but not waterlogged

Fertilizer Type:

• - Right after transplanting: Use a fertilizer with a higher middle number (phosphorus) to encourage strong root growth. A 12-24-12 formula is ideal, but if that’s not available, look for something like 10-20-10 or 11-22-11. Apply 1 teaspoon per plant, keeping it at least 2 inches away from the stem to prevent root burn.
• - 7, 14, and 21 days after transplanting: Switch to a fertilizer with a higher first number (nitrogen) to support leafy growth. A 20-10-10 blend is best, but if you can’t find it, look for something similar where the first number is the highest, like 18-9-9 or 21-11-11. Use 1–3 teaspoons per plant, adjusting based on the plant’s health.
• - Additional option: Apply Neptune’s Fish and Seaweed as a foliar spray to provide extra nutrients and boost plant vigor.
