Why Are My Marigolds Dying?

Marigolds (Tagetes) are beautiful plants that produce bright yellow flowers. They can be easily propagated from seed, and they grow well in most soil conditions. However, sometimes they just don’t stay healthy and there are some problems that can result in a Marigold plant dying.

The most common reasons for a Marigold plant dying are improper watering, over-fertilization, acidic soil pH, diseases, pests, or inadequate sunlight.

Why Are My Marigolds Dying

If you are noticing that your marigolds are wilting and dying, it is most likely because you have been overwatering them or fertilizing them unnecessarily. Both of these actions can cause your plants to lose water and energy, which ultimately leads to the death of your marigolds.

Try not to overwater your plants, and only give them what they need in order to survive; this will help save your marigolds from destruction. Fertilize sparingly, if at all – too much fertilizer can actually be harmful to a plant’s health. By following these simple tips, you can keep your marigolds healthy and thriving – even during tough times like drought.


If you’re overwatering your plants, they will eventually die. Overwatering causes the soil to become saturated, which means it can’t hold water anymore. This water then seeps into the plant’s roots and eventually reaches the leaves.

  • Overwatering is a common problem that can kill your plants. The best way to avoid overwatering is to use a watering timer and adjust the water level accordingly.
  • Watering plants too much can cause them to become stressed, which can lead to problems such as wilting, brown patches on the leaves, and even death.
  • Too much water can also cause root rot, which will destroy the roots of your plants.
  • When watering plants, make sure to use enough water but not too much water; this will help you prevent over watering and loss of plant life.
  • Overwatering can be caused by a number of factors including incorrect irrigation techniques, heavy rainfall, or overwatering from a hose that has been left running overnight

Fertilizing Unnecessarily

One of the most common causes of wilting or death in plants is when they are fertilized unnecessarily. A plant needs fertilizer to grow and flourish, but if it’s applied too often or in the wrong doses, it can damage the plant’s roots, foliage and flowers.

Not Using the Correct Fertilizer

Not using the correct fertilizer can lead to your marigolds dying. There are a few things you need to keep in mind when fertilizing your marigolds: the type of fertilizer, how much to use, and when to apply it.


Watering your plants too much can kill them. Too much water can cause roots to rot, leaves to droop, and flowers to wilt. Aim for an occasional watering rather than frequent drenching.

Giving Your Marigolds Too Much Nitrogen

Nitrogen is one of the main components of fertilizer and is often used to boost plant growth. However, over-fertilizing with nitrogen can lead to excessive foliage growth and weak stems, which may eventually cause your marigolds to die.

Failing to Water Deeply enough

When watering your plants, make sure that the water reaches deep into the soil and roots area. This will help prevent moisture from being lost quickly through evaporation or direct contact with sunlight.

Not Sowing in Good Soil

A good soil mix should have plenty of organic matter (moss, straw etc.), good drainage qualities, and proper pH levels–all of which are important for healthy marigolds

How To Repot A Marigold

If you’re noticing that your marigolds are dying, it’s probably time to repot them. Marigolds need regular soil changes in order to stay healthy and grow tall. Follow these steps to repot a marigold:

1. Dig a hole twice the size of the plant’s root ball in moist, well-drained soil. Make sure the soil is evenly moist before planting.
2. Remove the old pot, if there is one, and place the marigold in the hole. Use a garden trowel or spade to spread the roots out as much as possible.
3. Add enough moist soil to cover the plant completely and tamp it down gently with your hand or the back of a rake. Water well until water runs out of the drainage holes at the bottom of the pot, then let dry between watering sessions.

  • Repotting a marigold is an easy way to ensure that the plant gets the proper amount of water and nutrients and that it stays healthy.
  • To repot a marigold, first make sure that the pot is empty and clean. Next, fill the pot three-quarters of the way with fresh soil mix. Make sure that the soil is evenly moistened before you add the marigold.
  • Once the marigold is in its new pot, water it well and fertilize it according to package directions.
  • Keep your marigold in a sunny location and away from direct heat or cold drafts during winter months.
  • Marigolds are hardy plants and will usually survive repotting if done correctly.

How To Water Marigolds

If you’re noticing that your marigolds are wilting and dying, there’s probably a reason why. Marigolds love water, but if you don’t give them enough, they’ll start to die. Try giving them a good soak every couple of days or putting them in a rain barrel.

Fertilize With Nitrogen

Marigolds are a succulent that need to be watered with nitrogen to help them grow. When you water marigolds with normal tap water, they will not get the proper amount of nutrients and they may die. To water your marigolds with nitrogen, purchase a Garden-N-Water fertilizer specifically for succulents and dilute it according to the directions on the label.

Water Regularly

Make sure to water your marigolds regularly in order for them to thrive. Marigolds are prone to wilting if they do not receive enough water. Water the soil until it is saturated then wait an additional hour before watering again.

Avoid Overwatering

Watering too much can kill your marigolds, so make sure to avoid watering them more than once a week if possible. Over watering can cause roots to rot and leaves to droop.

Monitor The Plant’s Progress

If you notice that your marigold is starting to look unhealthy or its leaves are wilting, stop watering it immediately and consult a gardening expert for assistance. If you continue to neglect your plant, it may eventually die due to lack of hydration.

Why Are My Marigolds Dying

If you’re noticing your marigolds are wilting and dying, there may be a few reasons. One possibility is that the soil in which they are growing is too dry. Another possible cause is overwatering. If you see this happening repeatedly, it might be best to consult a gardening expert for help.


Water can be a major cause of wilting and dying plants. Over watering can lead to root rot, which will kill the plant. Marigolds are particularly susceptible to this type of damage because they are often used as ornamental plants.

Fertilizing Late

It is important to fertilize your marigolds at the correct time of year in order to provide them with the necessary nutrients. Fertilizing too late in the season can cause foliage damage and death. This problem is most common during colder months when there is less sunlight available.

Poor air circulation

Poor air circulation can also be a main cause of wilting and dying plants. Poor airflow can occur due to dense vegetation, obstructions within the planting area, or faulty ventilation equipment.

Insects and Disease

Insects and diseases can also be a big contributor to plant death. Insects like aphids feed on plant sap, which causes signs of wilting and eventually death. Diseases like spider mites spread through contact with infected plant material, which can lead to weakened leaves and even death in some cases.


Waterlogging is another common cause of wilting and dying plants. When water accumulates on the surface of the soil, it creates an environment that is hostile for plants and can eventually kill them off.

To Recap

Marigolds are susceptible to a range of problems that can kill them, so it is important to inspect your plants regularly and take any action necessary to prevent or fix any problems.

Many Marigolds plant problems have similar symptoms, so it is really important to inspect your plants carefully before deciding what action to take. It’s not always possible to fix a dying Marigold, but gardening is a continual journey of learning, so and we often learn far more from our failures than our successes.
