Marigolds

Marigolds are very low-maintenance once established, and they are notably pest-free. In fact, they are often used to keep pests away. Marigolds can bloom almost non-stop and will keep going all summer, until frost. To achieve that non-stop flowering, keep your marigolds deadheaded.For the most flowers and the healthiest plants, plant your marigolds in full sun Any good garden soil (and a little water during dry spells) should keep them happy, as long as the soil is not too acidic. Keep the soil pH above about 6.0. They also don't need a soil that is particularly rich in organic matter and seem to grow better in a leaner soil.
