As such, they should be planted outdoors in the late fall, or treated seeds can be sown indoors in the spring 8-10 weeks before frost season ends.Planting should be done AFTER a killing frost in your area, or after you’re quite sure the growing season has ended, and your seed won’t sprout until spring. In heavy winter areas, that means from late September or October up until the ground freezes.
How to start geum seeds?
Geum seeds benefit from a cold stratification treatment before planting. This can be done naturally by sowing the seeds outdoors in the late fall, allowing winter weather to prepare the seeds by spring. Or, you can mix the seeds in sand inside a plastic bag, placing it in the fridge for 3-4 weeks before sowing. Sowing means planting a seed or putting the seed in the soil. Sow seeds early in the morning so the water has enough time to permeate the soil and get warm throughout the day. You can do it in the evening but make sure the seed flats stay warm overnight.You can sown seeds at various times of the year, depending on the type and variety of seed. April is usually the time when there is a more intense flourish of seed sowing. The longer days and warmer temperatures mean that the conditions for sowing successful seeds outside are better.As a general rule, seeds are started indoors about 6 weeks prior to your last frost date. During a cold spring, it’s better to delay sowing to ensure the soil temperature is warm enough than to be hasty and get disappointing results.
Do geums only flower once?
No, Geums will flower throughout the summer, and will keep flowering if they are deadheaded regularly. Deadhead regularly to prolong flowering (taking flowered stems down to the ground). Geum has attractive seedheads which if left on the plant will last well into winter.
