3 Succession-Planting Programs for Single-Stem Sunflowers

3 Ways to Expand Your Sunflower Harvest

A season-long sunflower harvest can be achieved through succession planting. There are two basic ways to plant for a successive harvest, and a third, combination approach:

  1. Example Chart 1 • A single planting of multiple varieties that have different days to maturity.
  2. Example Chart 2 • Multiple plantings of the same variety at 7–14-day intervals.
  3. Example Chart 3 • Planting multiple varieties with varying days to maturity at 21–28-day intervals.

Use these charts as a guide to plan for a full season of blooms, modifying your dates according to the varieties you choose and your growing conditions.

A single planting of multiple varieties

The easiest way to succession-plant sunflowers is to grow several single-stem varieties with different days to maturity, planting them all at once, then harvesting over several weeks.

Multiple plantings of a single variety

A second way to extend your sunflower harvest is to plant a single variety on multiple seeding dates (7–14-day intervals). You then continue seeding and harvesting as long as your growing season will allow.

Multiple plantings of multiple varieties

The third approach is to plant multiple varieties with varying days to maturity. This combined approach requires fewer seeding dates (21–28-day intervals) and provides for the longest sunflower harvest window.
