You can’t plant a pumpkin without seeds. You’ve got two options here: You can either remove seeds from a fresh pumpkin that you recently bought or you could purchase seeds from a garden store. When you’re using store-bought seeds, there are lots of varieties to choose from. You can check online or get advice from the garden centre staff about which one matches your needs best. For example, if you plan on carving pumpkins, you want to choose a variety like a Jack-o’-lantern.
If you’re reusing the seeds from a pumpkin you’ve recently carved, make sure that you rinse the seeds and separate them. Then allow them to air dry. You can store them in a dark, cool space until you’re ready to put them into the ground.
It’s usually safer to plant store-bought seeds as the chances of them turning out the way you want are higher than storing your own seeds.
