how long do celery seeds take to germinate
The best way to germinate celery seeds is by starting the plants indoors in seed flats. Celery seeds take 14 to 21 days to germinate and emerge from the soil.When starting seeds indoors, use a seed-starting flat filled with a soil-less seed-starting mix. Commercial seed-starting mixes are designed to be porous, sterile and to provide good drainage, all important factors for good germination rates.hen celery seedlings grow 6 inches tall, about 10 to 12 weeks after starting seeds, they are ready to transplant out into the garden.
