Growing your own garden plants from seeds is not only fun and rewarding, it’s practical. You open the door to a wide range of varieties you won’t find at local nurseries. And for the price of one pack of annuals at the garden center, you can buy one packet of seeds and get 10 times the number of plants. Marigolds are among the easiest seeds to save. The most important thing is to make sure the seeds are completely mature and dry before you store them. You can let the flowers dry in the garden, or you can dry them after cutting them off the plants. Start with a bouquet of disease-free flowers past their prime for beauty. If the flowers are cut while in full bloom, the seeds will not be completely mature. Wrap a rubber band around the stems and hang the bouquet upside down in a paper bag in a cool spot. As the seeds dry, they will fall into the bag. Store the fully dried seeds in a covered jar in a dark, cool location (a refrigerator is ideal). Next spring you can start the fun again.
