Seed companies are businesses that specialize in producing and selling seeds for various plants, including vegetables, fruits, and flowers. They play a crucial role in agriculture by providing farmers and gardeners with high-quality seeds that are essential for growing healthy crops. These companies often invest in research and development to create new seed varieties that are more resistant to diseases and pests. In addition to selling seeds, many seed companies also offer resources and support to help customers with planting and cultivation. They may provide information on best practices for growing plants, as well as guidance on soil health and pest management. Some well-known seed companies include Burpee, Johnny's Selected Seeds, and Baker Creek Heirloom Seeds.
