Lots of calendars exist to help you organize your vegetable beds. Time to seed, time to transplant, time to harvest. But when planning a new flower bed I struggled to find something to help me organize my thoughts. Hence the bloom calendar- and now something you can use too.
Fill in however much you need. I like to color in each month (with the corresponding color of the plant). That way, I can ensure I have coverage across as much time as possible with a wide array of plants suitable for pollinators. I don’t much pay attention to gardening with a color theme, but when selecting a new plant to fill in a time or space without a lot of blooms, I do use the calendar to help me select which colors I should gravitate towards.
