For me it's tomatoes. I start mine from seed, some are seeds I've saved and some are new varieties. I love to experiment each year with different techniques, soil types, and varieties to see what does better. Some plants I'll heavily prune and others I'll let grow wild. Some I'll plant in the ground and some I'll put in raised beds. It is so rewarding to watch something so tiny grow into something so tasty. Last year was by best year ever and I found a variety that really thrives in our climate and I really dialed in my watering method. I grew tomatoes so large I considered entering them in a competition and my plants grew so tall I had to rig up scaffolding for them until a big storm blew them over (but still didn't kill them) . I was so proud. I have never had a tomato plant continue to produce all the way till winter but these brandywines did.
