What is the Lowest Temperature Marigolds Can Tolerate?

The lowest temperature marigolds can tolerate is 50 degrees Fahrenheit. Marigolds are not frost-tolerant, so they will not survive in temperatures below 50 degrees Fahrenheit. If the temperature drops below 50 degrees Fahrenheit, the marigold plants will die.

Marigolds are a beautiful and popular flower that can be found in many gardens. They are known to be fairly tolerant of different temperature ranges, but there is a lower limit to how cold they can tolerate. Marigolds can begin to experience damage at temperatures below 50°F.

This is because their leaves and flowers can start to freeze and thaw, which causes them to become discolored and wilted. In extreme cases, the plants may die. However, as long as the temperatures don’t dip too low for too long, marigolds should be able to bounce back once the weather warms up again.

Can Marigolds Survive a Freeze?

Yes, marigolds can survive a freeze. In fact, they are one of the hardiest annual flowers and can tolerate temperatures as low as 20 degrees Fahrenheit. However, if the temperature dips below this for an extended period of time, the flower heads will turn brown and die.

The leaves may also suffer damage, but the plant will typically recover once warmer weather returns.

How Do You Protect Marigolds from Frost?

If you’re growing marigolds (Tagetes spp.) in the garden, you’ll want to protect them from frost to extend the blooming season. Marigolds are annuals that grow best in full sun and well-drained soil. They come in a variety of colors including yellow, orange, and red.

There are several ways to protect marigolds from frost: – Cover the plants with a light cloth or frost blanket when temperatures are forecast to dip below freezing. Be sure to remove the cover during the day so the plants don’t overheat.

– Move potted plants indoors or into a sheltered area such as a garage or porch where they won’t be exposed to cold temperatures.

– Apply an anti-transpirant spray to the foliage of outdoor plants. This will help reduce moisture loss and prevent damage from freezing temperatures.

Can Marigolds Be Planted before Last Frost?

Yes, marigolds can be planted before the last frost. In fact, it is recommended that you plant them about 6-8 weeks before the last frost date in your area. This will give them time to establish themselves and bloom before the summer heat sets in.

When Can You Put Marigolds Outside?

Marigolds are annual plants, which means they only live for one growing season. They can be planted outside as soon as the last frost has passed and the soil has warmed up. In most areas of the country, that is late April or early May.

Marigold Temperature Requirements

Marigolds (Tagetes erecta) are one of the most popular annual flowers, known for their bright colors and ability to bloom throughout the summer. They’re easy to grow from seed, and they’re tolerant of a wide range of growing conditions. However, there are a few things to keep in mind if you want your marigolds to thrive.

One of the most important factors is temperature. Marigolds prefer warm weather and will do best in temperatures between 70-85 degrees Fahrenheit. If it gets too hot or too cold, they may stop blooming or even die.

So if you live in an area with extreme temperatures, it’s best to plant them in a protected spot or choose a different flower altogether. Another thing to consider is moisture levels. Marigolds don’t like wet feet, so make sure you plant them in well-drained soil.

If possible, elevated beds or containers are ideal. Watering should be done at the base of the plant rather than overhead to prevent fungal diseases. And finally, deadheading (removing spent flowers) will encourage continuous blooming throughout the season.

With just a little bit of care, marigolds can add beauty and color to your garden all summer long!

What Temperature is Too Hot for Marigolds

Marigolds are a popular choice for many gardens, but did you know that there is such a thing as too hot for them? Marigolds can actually suffer in temperatures over 85 degrees Fahrenheit. The leaves will begin to wilt and the flowers will droop.

If the temperature rises above 90 degrees, the marigold plants will start to die. So, if you’re growing marigolds in an area with high temperatures, be sure to provide some relief from the heat, such as shade or misting with water.

Can You Bring Marigolds Inside for the Winter

If you live in a climate where it gets cold in the winter, you may be wondering if you can bring your marigolds inside to keep them from freezing. The answer is yes! Marigolds are quite hardy and can withstand a fair amount of cold.

However, there are a few things to keep in mind if you want to successfully overwinter your plants. First, make sure to choose a variety of marigold that is suited for cooler temperatures. French marigolds (Tagetes patula) are a good option as they can tolerate frost and even some snow.

Second, gradually acclimate your plants to indoor conditions by moving them into a protected area outdoors for a week or two before bringing them inside for the winter. This will help them adjust to the change in temperature and light levels. Once they’re indoors, place your marigolds in an area that receives bright indirect sunlight and keep the soil evenly moist but not soggy.

Avoid drafts from windows or doors, as this can cause the leaves to brown and drop off. With proper care, your marigolds should thrive all winter long!

Can Marigold Seeds Be Planted in the Fall

Marigold seeds can be planted in the fall, but they may not germinate until spring. The best time to plant marigold seeds is in late summer or early fall, when the weather is still warm. Plant the seeds in a sunny location with well-drained soil.

Water the seeds regularly and keep them moist until they germinate. Once the seedlings appear, thin them out so that they are spaced about 6 inches apart.


According to the blog post, marigolds can tolerate temperatures as low as 50 degrees Fahrenheit. However, they will not flower if the temperature is below 60 degrees. The author recommends covering them with a frost blanket or bringing them indoors if there is a chance of frost.
