I bought a marigold plant two weeks ago and it started by a beautiful bloom. However, some of the biggest flower slowly becomes brown and wilted. The leaves are curling and dried too. So I cut out the dried part.

I am not sure if it's due to overwatering, underwatering, or fungus? The other buds are okay and seems to bloom just fine. It's just quite many leaves and small branches are drying, it makes me worry. The stem is not mushy, though.

I live in Southeast Asia, which has a tropical climate and sun all year round. The plant was placed in west-facing balcony, so it receives a full sun from 1pm to 5pm. Water it once a day except during rain, so the soil is pretty moist but not flooded. I thought Marigold likes sun, because the seller put it on the open space instead of in the shade and they were fine and healthy when i bought it. I haven't changed the potting mix ever since I bought it.

Some people suggested to cut the flower, but I still left it because I wanted to get the seed out of it. But I am not sure if I can have it, looking at the flower condition.

Here is the picture: pic of wilted flower

The last time I picked the wilted flower, the seeds are underdeveloped. Could it be because no pollination was going on? There was also a fuzzy white spot (small one) which I am afraid is kind of fungus.

Anyone can give me suggestion on what's going on with it and what to do to make it healthy again?


  • Looks like fungus indeed, try to cut back the infected parts leaving only healthy parts before it may spread out.

Remove the spent flower by clipping it off just above the nearest healthy leaf. It looks almost as if its been exposed to quite a lot of rain, which will often cause this browned, soggy look to this type of marigold flower. When you water, just water the soil in the pot, keep the water off the flowers.

Your marigold is Tagetes erecta,common name African marigold - these can get up to 120 cm in height and should be quite big, bushy plants. One of the problems your plant/s have is the size of pot they're in - they need to be in bigger pots with more soil available for their roots, so find some larger containers with drainage holes and move them, carefully, packing more potting soil around the root balls in the new pots. Afterwards, water in well, allowing excess water to drain away freely. Ongoing, you may need to water a bit more often, but you can check by feeling the top of the soil with your finger, and if it feels just about dry, water thoroughly - you need not worry about overwatering so long as any excess water is able to drain away readily from the bottom of the pot. Full sun is usually recommended for these in places like the UK, but where you are I assume you have higher temperatures and hotter sun, so half a day's sun is fine.

One other thing - you have used the 'houseplant' tag, but these plants do not do very well as houseplants.


It needs more root space. Try that first, as for the flower itself, they do that during blooming season. You pull the flower off and harvest the seeds. It will help the plant continue to put out new blooms all season long.

It sounds to me like the plant is stressed out and overwatered. When the plant is stressed, it invites pests. You will want to treat the soil, spray the plant leaves, and look underneath the leaves for signs of bugs. Identifying what bugs you're dealing with is critical to knowing how to attack. The main thing you will want to do is remove the affected leaves and allow your plant to slightly dry out before watering again. Keep in mind marigolds don't like a lot of water

It sounds like your marigolds may be feeling a bit stressed. Several factors can cause drying of flower and curling of the leaves in marigolds.

Over-watering can lead to root rot, which can cause wilting. On the other hand, under-watering can also cause the wilting of flowers and curling leaves.

Marigolds generally require a good amount of sunlight to thrive. If they're not getting enough sunlight, they may wilt.

Lack of essential nutrients can cause wilting and other symptoms. Consider using a balanced fertiliser according to the manufacturer's instructions.

Check your marigold plant for signs of pests such as aphids, spider mites, or diseases like powdery mildew. These can cause damage to the plant.

Extreme temperatures, either too hot or too cold, can stress marigold.

Inspect your plant closely to identify any signs of the above issues, and take necessary actions to address them. If you're unsure, you can consult with a gardening expert.
