How to Grow Marigolds

Marigolds are an annual plant that offers an impressive array of colors to enhance your garden. They are easy to grow and do well in most areas. They are also very hardy, thriving in temperatures as low as 20 degrees.

They are drought tolerant and bloom well into the fall. They can be grown from seed, either directly sown into the garden or started indoors a few weeks before the first expected frost date.

These flowers can be planted in beds and borders, in mixed plantings, and in containers on patios or decks. They are a favorite of many gardeners because they do not require much attention and can provide a spectacular show for the entire summer.

Their bright, bold colors and dazzling rays of sunshine make them an ideal addition to any flower bed or landscape design. They are suitable for planting in full sun to part shade and can thrive in both dry and wet conditions.

The most common types of marigolds include the French and African varieties. These are tall, compact perennials that produce double flowerheads up to 2 inches across. They come in shades of orange, yellow, red, and gold, some with highlights of copper or brass.

For the best blooms, plant your marigolds in full sun. In shady areas, they will become leggy and flower less robustly.

Deadhead spent flowers promptly to promote further blossoms. Cut spent flowers from the stem, as close to the next leaf node on the plant as possible. Pinch new growth to encourage bushier plants, which will also increase the amount of flower buds and blossoms.

Pinching the tips of young marigolds will force them to branch out and eventually form fuller, bushier flower stalks. It also helps keep the plant from getting too leggy and causing it to die back early in the season.

To help your marigolds thrive, water them regularly but do not soak their leaves when you do. Overwatering may cause their foliage to break off and the plants to become droopy and sickly looking.

If you plan to plant marigolds in a container, a light dressing of mulch can help conserve water and discourage weeds from forming. Apply about an inch of mulch between each set of plants.

Avoid heavy potting soil, as it can be too difficult for the plant to absorb the nutrients it needs. Instead, mix in a granular slow-acting fertilizer at planting time and irrigate with diluted liquid fertilizer as needed.

Use a soil pH that is roughly neutral, from 6.0 to 7.0. This will ensure that the plants have a healthy root system and that the soil is not too acidic, which can cause the roots to decompose more quickly.

A good quality soil is essential to the success of any marigold. It should be free of weed seeds and have an organic matter content that is high enough to support the root development and growth of the plant.

In general, marigolds prefer rich, slightly moist but well-drained soil with a pH range of between 6.0 and 7.0. They are a bit more fussy about soil moisture than other flowers, but they can usually handle dry periods with ease. A light application of mulch will make your marigolds less likely to wilt and can keep the soil cooler in hot weather.
