Signet Marigold

Mounds of lacy foliage and a mix of bright paprika, pumpkin orange, and lemon yellow-color blossoms lend Signet marigold a delicate, refined appearance that is quite unlike its relative, the marigold. Just as easy-to-grow from seed and as long-flowering as the more common large marigold, Signet marigold is a vintage plant that is regaining popularity. Add this little wonder to containers and garden planting beds for months of easy-care color.

Signet Marigold Care Must-Knows

Signet marigolds grow best in full sun and moist, well-drained soil. They will tolerate periods of drought after they establish a strong root system. Start plants from seed or from transplants. Seeds can be started indoors 4 to 6 weeks before the last expected frost. Plant seeds 1 inch apart in a container of well-drained seed starting mix. Plant seeds ¼ inch deep, and keep the soil moist until you are ready to transplant them outside.

Or, you can sow seed directly into well-worked garden soil once all danger of frost is past. Space seeds 2 to 3 inches apart and plant them ¼ inch deep. Marigold seeds germinate quickly, so expect to see fine, grasslike foliage pop out of the ground about 7 days after planting. Water plants regularly for the best blossom. Fertilizing can improve flowering, but it is not necessary. If you decide to fertilize, use an all-purpose fertilizer every couple of weeks, following package application directions carefully. If plants become tall, lanky, and bedraggled looking, cut them back by half their height, and they will send forth new foliage and blossoms.

Geraniums have been a gardener's favorite for well over a century. The old-fashioned standard for beds, borders, and containers, geranium is still one of the most popular plants today. Traditional bedding types love hot weather and hold up well to dry conditions; many offer colorful foliage. Regal, also called Martha Washington, geraniums are more delicate-looking and do better in the cool conditions of spring and fall.Though most geraniums are grown as annuals, they are perennials in Zones 10-11. Bring them indoors to overwinter, if you like, then replant outdoors in spring. Or they can bloom indoors all year long if they get enough light.
