They don't come much easier than the common marigold. It's
a plant that will stand up to the hot summer sun and smile back with its
own sunny yellow, orange, or bronzed-hued face.
Marigolds can laugh at bugs too. One sniff of its pungent
leaves and most insects head for the next county. In fact, some people plant
them around more vulnerable flowers in order to act as a natural insect repellent. This is known as companion planting. There is even a bug spray made from the plant. Marigold bug spray
Marigolds can bloom all summer especially if you keep the spent
flowers from going to seed by plucking them. You can encourage their growth by giving them manure tea or liquid fertilizer every four to six weeks. Marigolds are grown in masses, along border bed and in containers.
The plants are easy to grow from seed and are also available in
six packs from every garden center. There are basically two types of marigolds, shorter, more commonly grown French marigolds and taller African marigolds. (see below) Put them in a sunny spot and they will
grow from 12 to 18 inches and bloom a riot until Jack Frost calls an end
to the party.
Starting marigolds from seeds is also a fine way to introduce
children to gardening. Save some of the seeds and plant them next year if you want to demonstrate how flowers are a plant's way of making new plants.
