Get a jump on next season!
Sowing perennial flower seeds in late summer and fall will give you a head start on those second-year perennial blooms! Why now? In nature, after perennials have flowered, they drop their seeds right around this time (late summer/fall). Those fallen seeds germinate just as the conditions become right; in other words, as soon as possible.
4 Reasons to Sow
Perennials in the Fall
1. Hassle-free stratification: Some perennials' seeds need stratification-periods of cold temperatures combined with moisture (like that from snow and rain during winter) to break a natural dormancy, allowing them to germinate. Take advantage of nature's process by sowing in the fall.
2. Earlier blooms and larger plants: Perennials live for more than two years, and can take several years to get to their mature size. By sowing perennial seeds in the fall, plants will be more mature the following year than if spring sown, allowing many types to flower their first growing season.
3. Care-free moisture management: Most regions have winter rain and/or snow, providing essential moisture without you lifting a finger. Cool weather also reduces the need to water as frequently, when rain and/or snow is not adequate.
4. Control weeds with ease: Cool weather slows weed germination and growth, making your nicely prepped and sown garden area easier to maintain in the upcoming season.
