A garden journal is the best way to keep track of your garden's harvest so that you can plan for the future. Write down how many plants you grow, how far apart they are, when you plant and when you harvest them, and how much each plant or row produces. Write down what worked or did not work for each type of plant. Over time, this historical information becomes very useful because it helps you replan your plantings, rotate your crops better, and start the right number of seedlings each season to meet your goals for consumption and storage. Digital gardening apps can also be a convenient tool for tracking your garden's progress and yield, offering the added benefits of reminders and community advice.
