It’s essential to note that expired pumpkin seeds may have a lower germination rate, and the resulting plants may be weaker or more prone to disease. To plant expired pumpkin seeds, make sure to provide them with optimal growing conditions, such as plenty of sunlight, water, and nutrients. You can also try to test the seeds for viability by soaking them in water and checking if they sprout.
