As far as flower-growing is concerned, marigolds definitely fall into the fool-proof category. Wait to plant their seeds until after the spring frosts have come to an end. Just about any bedding type will suit them, although moist, well-drained soils are preferable. Marigold enthusiasts usually get their seeds by purchasing them in packets, which come with specific instructions about spacing and other topics. Cover the seeds with a small amount of dirt, don’t let the soil get too dry, and uproot some of the seedlings as needed. In exchange for this minimal effort, you’ll get vibrant flowers that will stick around until football season.
