Marigolds are a great choice for the beginning gardener. Children as well as adults love them for their brilliant orange and yellow hues and their ease of growth. They can survive in less than ideal soil, and will produce blossoms from early summer right up to the first frost. The most common varieties grow to a height of 6-8 inches, but there are others that may reach three or four feet.
Although marigolds are easy to start from seed, most garden centers have an abundant supply of established plants ready to set directly into your garden. The one requirement is a sunny location. Once any danger of frost has passed, plant them at the same depth or slightly deeper than the dirt enclosure in which they came. Space them 6-8 inches apart and water well. Continue to water them throughout the summer when the soil feels dry. Removing the dead flowers will allow the plant to use its energy for future blossoms.
