Gardening books will tell you that when growing Bachelor Buttons, they should be planted in full sun. But this gardener can tell you from experience, that they grow well on a slightly shaded side of the house, too. While we suggest you strive to provide them with full sun, a little shade should not hurt their growth.
The plants will do well in average soils and tolerate dry soil conditions. Soil should drain well.
Add a general-purpose fertilizer once a month.
Water the plants during the hot, dry summer months.
Keep young plants well-weeded. Then, mulch around the plants to keep weeds down and help retain soil moisture.
Once your plants are established, they will produce a burst of flowers, then slow down their production. Flowers will continue at a slow, regular pace even after a light frost.
While they are annuals, the plants are somewhat hardy. Growth may slow as the weather gets colder. But they often survive a light fall freeze.
Garden tip: Deadhead spent blooms to prolong the blooming period.
Ideal Soil pH: 6.8 – 7.2.
