I am starting seeds for several varieties of primula for transplanting outdoors in February. When should I start these seeds for February bloom? |
Seeds of primula require a pre-chill prior to germination, so you can place them in the refrigerator for 8-10 weeks and sow them indoors, or you can plant them outdoors in the autumn and they'll go through a natural chill. If you want them to bloom in February, you should start the seeds as soon as possible. Primula species need time to mature before they'll bloom. |
