Buying Guide: Key Purchase Considerations
- Seed Type and Heritage: Heirloom and open-pollinated varieties preserve flavor and adaptability, while non-GMO options may appeal to strict purity preferences. Consider your climate and soil when choosing a heritage variety.
- Germination And Growth: Look for seed packets with clear germination rates and planting instructions. Many varieties favor cooler climates or shorter growing seasons, so match to your USDA zone.
- Planting Method: Some types benefit from direct sow, while others perform better started indoors and transplanted. Certain colorful or ornamental types require cluster planting for proper pollination.
- Pollination And Spacing: Corn is wind-pollinated; ensure adequate spacing or block planting to maximize pollination. Decorative varieties may have different spacing needs than sweet corn.
- Harvest Timeline: Maturity ranges vary by variety (e.g., 75–100 days vs. around 90 days). Plan your planting schedule around your growing season length.
- Organic And Certification: If organic certification matters, verify certifications and filtering for non-GMO and organic seed lines.
- Seed Availability and Packaging: Check seed counts per packet and whether seeds are sold in bulk, especially for large plots or survival gardening.
