Bachelor buttons are often confused with mountain bluets, as they are both called cornflowers. Ensure you get the right flowers by checking the scientific name. You want the annual Centaurea cyanus, not the perennial Centaurea montana. [2] X Research source
For cold climates, start your seeds indoors 6-8 weeks before the last frost, then transfer them outdoors. [5] X Research source
Bachelor buttons grow best in a sandy loam topsoil. You can also ensure an alkaline pH while adding drainage by mixing gritty materials like lime into your original garden soil.

Add about a 2 in (5. 1 cm) layer of mulch around the base of the plant after seeds have sprouted to prevent too much evaporation in drier areas. [12] X Research source Look for mulches that include organic materials, like shredded bark. When placing the mulch, make sure it does not touch the stems. This can transfer diseases that will harm your bachelor buttons down the line.
To attract more birds, bees, and other wildlife with their bachelor buttons, feel free to limit deadheading. [16] X Research source
Guarantee a full bloom by cutting your bachelor buttons in the morning. Flowers that have not yet opened will do so as the day goes on, making them ideal for bouquets. [18] X Research source
