When it comes to gardening, marigolds are a popular choice for many enthusiasts. The question of whether marigolds are perennials often arises, and the answer lies in the type of marigolds you're growing. In this article, we'll delve into the world of marigolds, exploring which ones are perennials and which are annuals, and provide you with step - by - step instructions on planting marigold seeds.
First, let's understand the difference between annuals and perennials. Annual plants complete their life cycle in one growing season. They germinate, grow, flower, produce seeds, and then die all within a single year. Perennial plants, on the other hand, live for more than two years. They may die back to the ground in the winter but regrow from their roots in the spring.
There are several types of marigolds, and their categorization as annuals or perennials can vary. Tagetes erecta, also known as African marigolds, are typically grown as annuals. These marigolds are known for their large, showy flowers and can add a splash of color to any garden. They are native to Mexico and Central America and thrive in warm, sunny conditions. African marigolds usually grow to a height of 1 to 4 feet and come in a variety of colors, including yellow, orange, and white.
Tagetes patula, or French marigolds, are another common type. Like African marigolds, they are also mostly grown as annuals. French marigolds are smaller in size compared to African marigolds, usually reaching a height of 6 to 18 inches. They have a more compact growth habit and are often used as border plants or in containers. Their flowers are smaller but more numerous, and they come in colors such as red, yellow, and bicolor combinations.
However, there are some marigolds that can be considered perennials in certain climates. Tagetes lemmonii, also called mountain marigold or Mexican bush marigold, is a perennial species. It is native to the southwestern United States and northern Mexico. This marigold has a shrubby growth habit and can reach a height of 3 to 6 feet. It produces small, yellow flowers and has a strong, pleasant fragrance. In regions with mild winters, it can come back year after year.
Now that we've identified which marigolds are annuals and perennials, let's move on to planting marigold seeds. The first step is to choose the right time to plant. Marigold seeds should be sown indoors about 6 to 8 weeks before the last frost date in your area. This gives the seedlings enough time to grow strong before being transplanted outdoors.
Prepare a seed - starting tray or small pots with a good quality seed - starting mix. Moisten the mix before sowing the seeds. Place the marigold seeds on the surface of the mix and gently press them in, but don't cover them too deeply as they need light to germinate. A light sprinkling of the mix over the seeds is sufficient.
Keep the seed - starting tray in a warm place, ideally at a temperature of around 70 - 75°F (21 - 24°C). You can cover the tray with a plastic dome or plastic wrap to help retain moisture. Check the soil regularly and keep it moist but not waterlogged. Once the seeds germinate, which usually takes about 3 to 7 days, remove the plastic covering and place the seedlings in a sunny location. A south - facing window is a good choice, or you can use grow lights if natural light is limited.
As the seedlings grow, you may need to thin them out. Leave the strongest seedlings in each pot or cell of the seed - starting tray. When the last frost date has passed and the soil has warmed up, it's time to transplant the marigold seedlings outdoors. Choose a location in your garden that receives full sun, at least 6 hours of sunlight per day.
Dig holes in the garden bed that are slightly larger than the root balls of the seedlings. Gently remove the seedlings from their pots and place them in the holes. Fill in the holes with soil and gently press the soil around the base of the seedlings. Water the transplanted seedlings well to help them establish in their new location.
Marigolds are relatively low - maintenance plants. They don't require a lot of fertilizer, but you can apply a balanced, slow - release fertilizer once or twice during the growing season. Water them regularly, especially during dry spells, but avoid over - watering as this can lead to root rot.
Deadheading, or removing the spent flowers, can encourage the marigolds to produce more blooms. Simply pinch off the faded flowers at the base of the stem. This will also keep the plants looking neat and tidy.
In conclusion, understanding the difference between annual and perennial marigolds is essential for successful gardening. Whether you choose the annual varieties for a burst of color in one season or the perennial types for long - term enjoyment, marigolds are a wonderful addition to any garden. By following the step - by - step instructions on planting marigold seeds, you can enjoy a beautiful marigold garden year after year.
