Tip: Be sure to read the seed packets before planting. Some seeds may need a head start indoors before moving outside.
Depth: General rule of thumb is to plant no deeper than a seed’s diameter. It is better to plant too shallowly than to plant too deeply. Seeds need air and moisture to germinate.
Space: Seed spacing refers to how closely you should plant your seeds. Spacing seeds reduces overcrowding.
Harvest: Harvesting applies to produce that you will be eating. Not all seed packets have this information. The number on the packet is subjective and gives you a general idea of when you can expect to get your vegetable or fruit.
Climate zones: Zone maps on seed packets were developed by the United States Department of Agriculture. This allowed farmers and gardeners to know which plants grow best in their area. The map listed on the seed packet shows when an indoor plant can be transplanted outside.
