Marigolds
Marigolds are common annual plants grown in many garden settings here in southern Illinois. The long flowering period and relative ease of growing marigolds make them a popular choice in many gardens.
The scent of marigolds is very strong. Some literature gives this plant credit for repelling insects. Though many gardeners like their smell, some find it repulsive.
Marigolds are suitable for containers or as mass plantings. Their deep orange or bright yellow color will brighten any garden. Today, there are many shades of crimson, orange, or yellow to choose from.
Planted in early spring these plants will bloom through fall with proper care. Mulch helps conserve moisture and monthly fertilization will keep plants growing. Dead heading, which is removing spent blooms, keep the flowers showy.
Large thriving plants or container plants will require additional water in hot weather.
Marigolds prefer full sun and the plants should be spaced 6-24" apart. Of course, dwarf varieties should be closer. That's right, the variety choices go from dwarf to near four feet so read the label of the variety you choose. Marigolds can be direct seeded into their location or one can purchase transplants.
Marigolds are attractive to butterflies as well. Butterflies do prefer the single petal varieties though. This colorful flower can be an aromatic addition to any landscape. Remember to add it next year.
