There are few things more satisfying than harvesting a crop you tendered from seed.
Some plants do best started directly in the garden (carrots, spinach, turnips, corn, lettuce, potatoes, onions, etc. etc. etc.), but others can be brought inside or housed in a cold frame to give you a head start in areas where the growing season is iffy for those hot loving vegetables. In the US Northeast. these include peppers, tomatoes, eggplant and whole lot more. gaining an extra month or more on the season with protected seed starts can mean the difference between an impressive harvest and a first frost just prior to picking time.
Other plants (like sage, okra, etc.) tend to take a long time to germinate and don’t compete well with weeds. starting seeds in containers with these plants can mean the difference between a prolific crop and one that succumbs to competition.
It’s so much fun to feel responsible for raising what you eat. Consider trying a just a few varieties to start. You’ll make mistakes, but enjoy the learning experience and wisdom you gain from learning what works for you – and what doesn’t.
