Vegetable Garden Fertilizer: Balanced or High Potassium, Plus Organic Matter

Great vegetables start with soil organic matter. Fertilizer fine-tunes production.

Best Formulas

• Balanced: 10-10-10, 14-14-14, 20-20-20.
• High potassium: 10-10-20, 5-5-10, or side-dress with sulfate of potash (0-0-50).

What to Avoid

• Lawn fertilizers (29-3-4) — too much nitrogen.
• Bloom boosters (10-50-10) — excess phosphorus.

Foundation First

Annual compost incorporation is the #1 factor. Fertilizer + organic matter + consistent watering + label timing = excellent yields.
