• Weeding: Remove weeds weekly to minimize competition for nutrients.

Pro Tip: Water early in the morning to reduce fungal issues.

12. Pest & Disease Management

Integrated Pest Management (IPM) keeps issues at bay without harsh chemicals:

• Companion Planting: Grow marigolds, nasturtiums, and chives to deter pests.

• Organic Sprays: Apply neem oil or insecticidal soap at first signs of infestation.

Pro Tip: Scout your garden daily to catch problems early.

13. Harvesting & Storage Guide

Proper harvest timing and storage maximize flavor and shelf life:

• Corn: Harvest at “milk stage” when kernels release milky juice; shuck and blanch immediately, then freeze.
• Beans: Pick when pods snap crisply; store unwashed in perforated bags in fridge up to 5 days.
• Pumpkins: Cure in sun for 7–10 days, then store in cool, dry place (50–55°F) for up to 6 months.
• Peppers & Tomatoes: Ripen on vine for best flavor; refrigerate only if fully ripe, then use within 3 days.
• Zucchini & Dill: Use fresh within 2–3 days or chop and freeze in ice-cube trays with water.
• Sunflowers: Dry heads upside down in paper bags; extract seeds once fully dry.

Pro Tip: Label and date frozen veggies in airtight containers to track freshness.
