Marigolds will always remain one of my favorite plants to grow indoors because of their gold and copper-colored flowers’ ability to bloom cheerfully throughout summer. Unfortunately, their beauty is not enough to protect them from drooping. So, what causes these plants to droop, and are there any fixes?
Your marigolds are drooping because of inadequate care or pests and diseases. Overwatering or a poor water drainage system can cause your marigold to wilt and droop. Other factors like pests, diseases, and inadequately-sized pots could also make your plant droop.
Similar to all living things, plants respond to environmental changes. If your marigold’s leaves and flowers start to droop, there’s a problem. So, keep reading to learn more!
1. Inadequately-Sized Pots
Using a small pot for your marigold may not seem like a problem. But as your plant grows, its roots will need to expand. There are two major marigold species; the African Marigold and the French Marigold. Although these marigold plants possess fibrous roots—which are shorter than tap roots—they still need enough room to grow.
When you leave these plants in poorly sized pots, they tend to get rootbound. Their roots coalesce into a densely-packed shape that will not allow the plant to grow further.
How To Fix
If you want to fix this, the first thing you’d need to do is to repot your plant. Remove your plant from its current pot, and loosen the densely-packed roots.
Purchase a bigger pot that can accommodate your plant’s roots. 8 and 9-inch (20-22 cm) pots are the best way to go.
Furthermore, I highly recommend you change your potting mix—reuse one-third of the original potting mix surrounding your annual plant for best results.
Wilting is a condition that can affect any plant. Simply put, it is the process where a plant becomes limp because of several factors like improper access to heat, sunlight, and water.
Wilting and drooping are very similar concepts. More often than not, one of the earliest symptoms of wilting is droopy leaves.
Your marigold needs the right amount of water, sunlight, fertilizer, and humidity to grow. Without these, wilting may occur. When a plant wilts, it loses its sturdy structure and cannot stand upright, causing the plant to droop.
How To Fix
Keeping your marigold plant from wilting and ultimately drooping requires paying attention to its needs. So, I recommend you ensure your plant receives just the right amount of nutrients, water, and sunlight. Letting it get these allows your plant to feed itself properly and, thus, maintain its sturdy structure.
Also, ensure you use room-temperature water when watering your plants. Allow the surrounding soil to dry out between watering sessions. Water thoroughly, and your plant should stop dropping or wilting in no time.
Many marigold species are susceptible to diseases like powdery mildew, rust, botrytis blight, and even root rot. What’s worse is that these diseases are challenging to detect in their early development stages. Although marigolds can withstand quite a lot, it’s not invulnerable to infections.
Many of these diseases will make your plant’s leaves droop and fall off in extreme cases. In addition to dropping, each of these diseases affects your plant differently.
For example, botrytis blight not only makes your plant droop but also makes its leaves turn papery brown. Root rot—caused by several pathogens— causes the general degradation of your plant’s foliage. Over time, these diseases can kill your plant if left untreated.
How To Fix
I recommend spraying with fungicides or neem water. This measure will protect your plant from contracting common diseases like powdery mildew.
Regularly groom and inspect your plant for more severe conditions like botrytis blight and root rot. If you see any infected spots, prune them from the main body of the plant.
Pests are annoying creatures that can negatively affect your marigold. Like many other plants, they are affected by garden pests such as aphids, earwigs, caterpillars, and spider mites. It’s essential to keep your plants as pest-free as possible.
How To Fix
Getting mild infestations is usually an easy fix, as pest repellents will do the trick. For more severe cases, you may have to cut off several parts of your marigold plant to prevent infestations from spreading. If you see any visible pests, handpick and dispose of them.
5. Poor Air Circulation
Many beginners and veteran gardeners underestimate the importance of air circulation to their plant’s health. The marigold is one of those plants that require constant air circulation to remain in top shape. If this plant doesn’t get gentle, constantly flowing air, its stem won’t be able to hold leaves up correctly.
How To Fix
Indoor plants naturally get less airflow than outdoor plants. Luckily, there’s a quick fix for this. The best thing for plants like this is to place them near a window where they can benefit from the air that comes in. Alternatively, you can introduce a gently-blowing fan.
6. Poor Soil Drainage
Many plant owners underestimate the dangers of improper soil drainage. Most plants dislike wet soil, but marigolds are particularly averse to it. Although African, Signet, and French marigolds generally love water, constantly sitting in it could pose several problems, like root rot and other fungal diseases.
Ultimately, the absence of an inefficient soil drainage system may cause your plant to droop and die in severe cases. If you don’t want that to happen, I suggest you use a well-draining pot.
How To Fix
Plant pots like carribean planters HC Companies Plastic Caribbean Planter (available on Amazon.com) are your best bet. This particular pot is highly durable while remaining lightweight and of course. It also has a contoured base that directs excess water to a removable drain plug.
A draining tray is also a good buy, especially if you bottom water your plants. Using a drainage tray will prevent water from remaining at your plant’s base. However, remember to properly dispose of water and replace the tray as soon as it begins to collect.
Finally, do not water your plants overhead. Instead, directly water the soil. Using rich, organic, well-draining soil will also significantly help water drainage.
7. High Humidity Levels
Humidity levels are always a topic of concern regarding the marigold. As I mentioned earlier, marigolds don’t thrive in constantly damp atmospheres. They also don’t respond well to extremely harsh weather. When exposed to these extreme conditions, they tend to droop and wilt.
How To Fix
Solving this requires you to track the air’s humidity at all times properly. These plants love dry, flowing air, so try to attain the appropriate humidity levels that facilitate suitable dry air. From past inference, this should be between 40 to 50%.
You can track the humidity of your air by using a hygrometer, available at your garden store or online.
8. Poor Watering
Overwatering is a common mistake. When your marigold starts to show signs of dullness, your first instinct might be to give it a drink. Although plants like water, too much can be harmful.
Alternatively, you could also decide to supply your marigold with little to no water to “correct” wet soil. While this isn’t inherently bad, taking this to the extreme will also cause your plant to droop as soil moisture drops to dangerous levels.
How To Fix
Rather than overwatering or underwatering your plant, it’s best to water occasionally but thoroughly during each watering session. Wait for the soil to almost completely dry out between each watering session.
If you’ve overwatered your plant, do not add any additional water for a week. Let the soil dry out before watering again.
9. Low Sunlight Exposure
Few plants love sunlight as much as the marigold. Provide this plant with ample sunlight and watch it bloom all year long. On the other hand, an inadequate amount of sunlight will make your marigold’s leaves and flowers droop.
How To Fix
Remember to give these plants adequate sunlight as a general rule of thumb. Plant them in sunnier parts of your garden rather than in shady areas.
If you’re growing this plant indoors, make sure you put them next to windows that supply a healthy amount of sunlight. These plants require at least six hours of constant sunlight daily to remain healthy.
Marigolds are amongst the most beautiful annual plants in the world. Initially discovered in Mexico and Guatemala, this annual plant can withstand quite a lot. However, when it doesn’t meet its daily requirements, it will likely start to droop to protect itself. Over time, drooping can cause plant death.
Thankfully, most problems are fixable if you don’t let them get too bad before you correct them. Regardless, prevention is better than curing, so keep an eye on your marigolds and ensure they have all they need.
