Growing Guide

When to Grow

Start seeds indoors 6 to 8 weeks before the last expected frost date, as ageratum is a warm-season annual that should not be transplanted outdoors until all danger of frost has passed. Seeds require light to germinate and should be surface sown without covering. Maintain warm soil temperatures of 70–75°F during germination for best results. In warm climates, a second sowing in midsummer can provide a fresh flush of fall blooms.

How to Sow and Plant

Surface sow Ball Mixed ageratum seeds by pressing them lightly into moist, well-drained soil without covering. Ageratum prefers fertile, consistently moist, well-drained soil and does not perform well in dry or compacted conditions. Space transplants or thin seedlings to 6 to 9 inches apart to allow for good airflow around the compact plants. Incorporating compost into the planting area before setting out transplants will support healthy, season-long growth and flowering.

How to Grow

Keep soil consistently moist throughout the growing season, as ageratum is sensitive to drought stress and will decline quickly in dry conditions. Mulching around plants helps retain moisture and moderate soil temperatures. Apply a balanced fertilizer every four to six weeks to support continuous flower production. Deadhead spent flower clusters regularly to keep plants tidy and blooming vigorously. In hot climates, partial afternoon shade can help extend the blooming season and keep plants looking their best.

How to Save Seeds

Allow a few flower heads to dry fully on the plant at the end of the season. Ageratum produces small seeds within the dried flower clusters; seeds are ready when the heads are fully dry and papery.

  • Cut dried flower heads and place in a paper bag to finish drying and capture any seeds that fall
  • Gently crush or rub dried heads to release seeds, then clean away chaff
  • Allow seeds to dry completely before storing
  • Store in a sealed container in a cool, dry, dark place for up to 2 years

Note that seeds saved from a mix may not reproduce the full range of colors in subsequent generations.
