How do I plan my first market garden season?

Follow the steps of Getting Started in order: they take you from a blank farm to a planned season, and Heirloom does the arithmetic along the way. Its crop values, built on the market gardener method, are already filled in, so your first plan starts from numbers that work.

1. Draw your field blocks and greenhouses with their beds: Create a field block.
2. Pick the crops you will grow this season: Choose your favorites for the season.
3. Add your plantings, and your successions in one entry each: Plan a succession.
4. Place each planting on its beds: Assign plantings to beds.
5. Follow the tasks your plantings create, week by week: How plantings create your tasks.
