Flowering can slow down in summer heat and then increase when it gets cooler.

Sunlight is important

Your marigolds should be in full sun to ensure the healthiest and most beautiful flowers. The plant will produce less flowers if it is under poor conditions.

Best soil for Marigold

Marigolds aren’t fussy about their soil. You can keep them on track with good garden soil and a little water during dry times. Make sure the soil isn’t too acidic.

The soil pH should range from 6.0 to 7.0. You also don’t need soil rich in organic matter. This plant actually grows better in a lighter soil.

How to Water Marigold

You should ensure that your marigold seeds and plants get regular water when you plant them. They shouldn’t be in dry soil for more than a couple of days. If it is hot and sunny, water your new plants every day.

Once they’ve established a good root system, they will be more drought-tolerant, but for the best blooms, give marigolds a weekly watering. Don’t water from overhead but rather at the base of the plant.

Humidity and temperature

Because they love heat, marigolds thrive in summer heat. They can tolerate a wide range in humidity levels, but may develop powdery mildew in humid or damp summers.

If you plant in full sun and allow room for airflow you shouldn’t have a problem. This plant  prefer relatively dry air.

Fertilising Marigold

Marigolds do not require fertiliser unless the soil is very poor. Don’t fertilise them during growth as too much nitrogen will stimulate lush leaves rather than flowers.

To control weeds and keep soil moist, add mulch between plants. This is especially important for young plants. We’ve learned a thing or two about types of mulch for the garden and when and how to use it. Our ultimate mulch guide is available.

How to prune marigold

Deadheading marigolds on a regular basis is the best way to keep them in bloom. Simply remove the flower heads and deadhead faded flowers by pinching them off.

This encourages the plants to produce more flowers and not waste energy on making seeds. Deadheading also makes marigolds more attractive. The African marigolds have thick, double flowerheads that can rot in wet conditions.

Are you unsure when to begin the deadheading process. When a flower starts to go bad, cut its stem back to the nearest set of leaves. A marigold plant will grow larger and produce more flowers if it is able to cut back its early flower buds.

Your marigolds will continue to produce new flowers through the autumn by regular deadheading. Marigolds can be pulled from the ground and thrown out when they are damaged by cold temperatures.

You can leave some plants in the garden to self-seed. The marigold seeds are not eaten by birds, but the heads of the flowers are ripped apart by birds. This helps in the self-seeding process.

Marigolds Plant Information

Marigold flowers can be used to treat a variety of skin conditions

Marigolds, which are native to Mexico or Guatemala, were discovered in the 16th century. They quickly grew in local gardens after being brought to Europe and Northern Africa in late 16th century. Tagetes, the genus name, is derived from a mythical Etruscan goddess.

Based on their scientific names, this plant can be divided into two categories. The first category includes varieties of the Calendula familyLatin name meaning ‘, which is a name that means ‘. “little clock”.

The second group of marigolds is from the The family of Tagetes. This name is a result of a religious prophet named Tages who influenced Etruscan culture. The common name Marigold comes from the plant’s use as an offering to the Virgin Mary instead of using gold coins.

Marigolds were a symbol of grief and despair in Victorian times. The modern meanings for marigold flowers are based on their sunny colour and beauty, and offer a message of optimism and success.

In the Middle Ages, Marigold plants were used to attract a lover.

Marigold varieties

Marigolds produce flowers that look a bit like daisies or carnations. There are about 50 different species, but most marigolds we see in the garden are one of the following:

Tagetes Erecta

(African marigold, American marigold, or Mexican marigold)

Tagetes erecta is the tallest and most upright marigold, and produces large, full flowers

This marigold is the tallest and uprightest, and it produces large, full-flowered flowers. They’re native to Mexico and Central America and will happily thrive in drought-like conditions.

Tagetes patula (French marigold)

Tagetes patula do well in rainy conditions more than the other Tagetes species

French marigolds are smaller than T. erecta and have a bushier and more compact appearance. They are also often larger than their height. They thrive in rainy conditions better than other Tagetes species because their flowers are usually plain.

Tagetes tenuifolia, Signet marigold

Tagetes tenuifolia like hot and dry sites and make a great edging plant

These miniature marigolds are great for edging and love to be in hot and dry areas.

Calendula Officinalis (Pot or English marigold)

This is a product that originated in southern Europe. “marigold”It is not a true margold. It has bright, edible flowers with a peppery, tangy taste.

Pot marigold is actually not a true marigold

How to Grow Marigolds

How to Grow Marigolds

Marigolds love sun and can withstand very hot summers. The signet and African marigolds are drought-tolerant, while the French marigolds will tolerate wet conditions more.

These plants can be grown in any soil but they thrive in well-drained, fertile soil. To make the soil fertile and more consistent, you can dig down to 15 cm.

Planting Marigolds

When to Plant Tagetes

You can plant young signet and French marigolds from spring to the middle of the summer. The taller African varieties should be planted immediately in spring, as they take longer to mature.

Sow seeds directly into your garden when the soil is warm in spring. You can start seeds indoors if you prefer, but they germinate so easily outside so it doesn’t really make a difference.

African marigold is an exception. It can be grown indoors for approximately 4 to 6 weeks. This plant can be grown in warm climates for about a week and will produce flowers in approximately 8 weeks.

How to Plant Marigold

If your soil is lacking nutrients, you can add some slow-release fertiliser, preferably organic, into the planting hole. A 5-10-5 would be a good choice.

Wet the soil, then sow the seeds 2.5cm apart and no more than 2.5cm deep. Space French and signet types 20 to 25cm apart. The larger African marigolds should be at least 25 to 30cm apart.

Use a soil-based mixture if you are planting in containers. We have gathered the best soil for containers here.

Mixing slow-acting granular fertiliser can be done at planting time. Marigolds grown in containers may become crowded if they are not spaced properly.

Marigolds as Companion Plants

Marigolds are valued as companion plants in the garden. For example, marigolds can be grown next to your vegetable gardens.

This plant tend to guard your veggies from nibbling rabbits and deer, since they don’t like the scent. Marigold flowers attract ladybugs as well as beneficial insects like bees. They repel unwanted visitors such as whiteflies, tomato hornworms, and cabbage worms.

French marigolds are a great choice as they protect your garden against harmful nematodes that live underground and attack the roots.

These microscopic worms most often attack tomatoes, cucumbers and snap beans. They also affect squash, onions, garlic, onions, and garlic.

Just something to consider, your marigolds’ water needs may be different than the vegetables they are planted with so you might need to water them separately.

How to Propagate Marigolds

How to Propagate Marigolds

Propagation Marigold starting from a Cutting

It’s actually quite easy. These are the steps:

Use sharp scissors or secateurs (Find the best secateurs online.To cut pieces of about 10cm long green stems, use a knife. The stems must not have flowers or flower buds. All leaves should be removed from the lower half.

The cutting should be coated with rooting hormone. Once it is soaked, place it in a small container containing a mix of potting soil and sand. Tap down the potting soil mixture around the cutting.

The pot can be placed in a plastic bag that is loosely tied to create a greenhouse effect. The pot should remain in a bright and warm place, but away from direct sunlight. Lightly water the potting mixture every four to five days.

Once the cuttings have rooted, you can transfer them to larger pots filled up with regular potting dirt. They should be established before you plant them in your garden.

Marigold Propagation starting from Seed

Marigolds can also be grown from seeds. The seeds are large, and easy to manage. Marigolds can be started indoors, but they will germinate quickly outside if you sow them directly in garden soil.

Many marigolds from last year self-seed so quickly that you may not need to plant any new ones once they are in bloom.

If you are going to start marigold seeds indoors, sow them on the surface of a tray or small pot filled with ordinary commercial potting soil that’s slightly damp.

Cover the seeds with a thin layer vermiculite, then cover the tray/pot with plastic. It should be placed in a warm place. You do not need to let the seeds germinate or sprout until they are fully grown.

After the seeds sprout, take out the plastic and place the container in a sunny area that receives four to five hours of light each day. Even artificial lighting is fine.

To keep the potting mix moist, water from below. This will allow the pot to absorb water from a tray. Once the seedlings have produced a lot of new leaves, they are ready for transplanting outdoors.

Marigolds are afflicted by pests and diseases

Marigolds have very few pests or problems

Marigolds are very resistant to pests. However, spider mites can infest them. These pests can be controlled by spraying water on the plants or using an insecticide soap for a few days.

If you need to bring in the professionals, have a look at our garden pest control guide to help you decide which one is best for your garden.

Marigold Fungal Diseases

Sometimes marigolds are affected by fungal diseases such as powdery mildew if conditions are too wet. A good way to prevent this is to avoid getting water on the marigolds’ leaves and plant in well-drained soil. Also, do your best in managing weeds.

Marigolds are easy plants from seeds. However they can die very quickly when the seedlings are just starting to grow. The stems become fragile and eventually turn black. This is known as damping off disease. It is a fungal disease that can be caused by many different species of fungi.

It is impossible to prevent it. However, you can make sure that your pots are clean and allow for air circulation. Also, keep your seedling trays warm.

Taller Marigold Varietyes Flop Over

Marigolds that are taller can become top-heavy and fall over when they are subject to strong winds or heavy rains. To prevent this, you can make the plants more deeply and remove the lower leaves.

This creates a large root system that helps to hold the plant upright. If necessary, you can also remove withered flowers right after they have bloomed.

Slow Blooming Marigolds

Marigolds can sometimes slow down in blooming during the hottest months of summer. These heat waves are a good time to prune the plants.

The plants produce strong growth and flowering when the temperature starts to cool in the late summer and early fall.
