Growing Tips for Bachelor's Button in Crenshaw County

Direct sow Bachelor's Button outdoors after March 12 in Crenshaw County when soil has warmed and frost danger has passed.

With Crenshaw County's clay soil (31% clay), work in 3-4 inches of compost before planting Bachelor's Button. Avoid tilling when soil is wet to prevent compaction.

Common pests for Bachelor's Button in this region include aphids and slugs. Use row covers early in the season and inspect plants weekly.

General growing tips

Direct-sow in early spring as soon as soil can be worked; seeds need a brief cold period for best germination (refrigerate for a few days before planting if spring arrives quickly). In zones 6+, fall-sow for the earliest spring bloom. Thin to 12 inches; do not over-fertilize — too much nitrogen produces foliage at the expense of flowers. Deadhead to prolong blooming or allow self-seeding for a naturalized colony.
