What Should I Do About Brown Stems On My Succulents?

If you’ve ever noticed your succulents looking a bit worse for wear, you’re not alone. Brown stems can be a common issue for these otherwise hardy plants, and figuring out what’s going on can feel a bit like detective work. But fear not—your succulent doesn’t have to suffer in silence!

In this post, we’ll chat about the possible reasons behind those brown stems, how to bring your plant back to its vibrant self, and some handy tips for keeping your succulents looking their best. So grab your watering can, and let’s get into all things succulent care.

Understanding Brown Stems: The Culprits

Brown stems on succulents can be caused by a variety of factors, each with its own telltale signs. To get to the root of the problem, it’s essential to consider what might be affecting your plant. Here are some common causes:

• Overwatering: Succulents are adapted to arid environments and don’t need as much water as other houseplants. Too much water can cause root rot, which often manifests as brown or mushy stems.
• Underwatering: While less common, underwatering can also lead to brown stems. If your succulent is too dry, the stems may shrivel and change color.
• Sunburn: Direct sunlight is great for succulents, but too much can lead to sunburn, causing discoloration and browning on the stems and leaves.
• Pest Infestation: Pests like mealybugs or spider mites can damage the stems, leading to browning and other issues.
• Nutrient Deficiency: If your succulent isn’t getting enough nutrients, this can also affect stem color and health.

Now that we’ve identified the potential suspects, let’s take a closer look at each one, and see how you can address these issues.

Overwatering: The Usual Suspect

Overwatering is probably the number one issue when it comes to succulents with brown stems. These plants store water in their leaves, which means they need less frequent watering than other houseplants. But what happens when they get too much water?

Excess water can cause the roots to rot, leading to brown, mushy stems. If you suspect your succulent is suffering from overwatering, here’s what you can do:

• Check the soil: If the soil feels damp, hold off on watering until it’s completely dry. You can stick your finger about an inch into the soil to test for moisture.
• Repot if necessary: If the plant is in soil that retains too much moisture, consider repotting it in a well-draining cactus mix.
• Adjust your watering schedule: Water only when the soil is dry, and make sure your pot has good drainage.

Remember, it’s better to underwater than overwater when it comes to succulents. They’re more likely to bounce back from a dry spell than from soggy roots.

Underwatering: The Other Side of the Coin

While succulents are drought-tolerant, they still need a bit of hydration to thrive. Underwatering, though less common, can also lead to brown stems. If the stems are shriveled and dry, this might be your problem.

Here’s how you can help:

• Increase watering frequency: Check your watering schedule and ensure your plant gets enough water, especially during the growing season.
• Soak the soil: When you water, do it thoroughly so that the water reaches the roots. Allow the soil to dry out completely between waterings.
• Monitor the plant: Keep an eye on your succulent to see if the stems return to a healthy color and plumpness.

Finding the right balance can take a little trial and error, but with some attention, your succulent should perk up in no time.

Sunburn: When Too Much Sun Isn't a Good Thing

Succulents love sunlight, but they can get too much of a good thing. If your plant is exposed to intense, direct sunlight, it might end up with sunburn, which can cause brown patches on the stems and leaves.

To protect your succulent from sunburn, consider these steps:

• Relocate: Move your plant to a spot where it gets plenty of indirect light but is shielded from harsh midday sun.
• Gradual exposure: If you’re moving your succulent outside for the summer, gradually acclimate it to the sunlight.
• Use sheer curtains: If you’re growing your succulents indoors, a sheer curtain can help filter intense sunlight.

With the right light conditions, your succulent will thrive without the risk of sunburn.

Pests: Tiny Invaders, Big Problems

It’s amazing how such small creatures can cause big problems for our plants. Pests like mealybugs, spider mites, and aphids can all damage succulents, leading to brown stems and other issues.

If you suspect pests, here’s how to address the problem:

• Inspect your plant: Look for signs of pests, such as small webs, sticky residue, or the bugs themselves.
• Remove pests manually: For small infestations, you can remove pests with a cotton swab dipped in rubbing alcohol.
• Use insecticidal soap: For larger infestations, insecticidal soap can be an effective treatment.
• Isolate affected plants: Keep infested plants away from others to prevent the spread of pests.

Regularly checking your plants can help you catch pest problems early before they cause serious damage.

Nutrient Deficiencies: Feeding Your Succulent Right

Just like us, plants need a balanced diet to stay healthy. If your succulent isn’t getting enough nutrients, this can lead to brown stems and other signs of poor health.

Here’s how you can ensure your plant is well-fed:

• Use the right fertilizer: Choose a fertilizer specifically formulated for succulents and cacti.
• Follow the instructions: Over-fertilizing can be just as harmful as under-fertilizing, so be sure to follow the package instructions.
• Feed during the growing season: Fertilize your succulents during the spring and summer when they’re actively growing.

With the right nutrition, your succulent will look healthier and more vibrant.

Proper Potting: The Foundation for Healthy Succulents

Sometimes, the issue might be as simple as the pot you’re using. Succulents need pots with good drainage and soil that doesn’t retain too much moisture.

Here’s what to consider when potting your succulents:

• Choose the right pot: Opt for pots with drainage holes to prevent water from pooling at the bottom.
• Use well-draining soil: A cactus mix or a homemade blend of potting soil, sand, and perlite works well.
• Repot when necessary: If your succulent outgrows its pot, repot it in a larger container.

With the right potting setup, your succulents will have the foundation they need to thrive.

Environmental Factors: Temperature and Humidity

Succulents are hardy, but extreme environmental conditions can stress them out, leading to brown stems and other issues. Here’s how temperature and humidity play a role:

• Temperature: Succulents prefer warm temperatures but can be damaged by extreme heat or cold. Keep them away from drafts and heating vents.
• Humidity: Too much humidity can lead to mold or rot, while too little can dry out your plant. Aim for a balance that mimics their natural desert habitat.

By keeping an eye on the environment, you can help your succulents stay healthy and happy.

Repotting: When to Give Your Succulent a New Home

Repotting might seem daunting, but it’s an important part of keeping your succulents healthy. If your plant is showing signs of distress, it might be time for a change of scenery.

Here’s when and how to repot your succulent:

• Signs it's time to repot: If the roots are growing out of the drainage holes or the soil isn’t drying out, it might be time for a new pot.
• Choose the right time: The best time to repot is during the growing season, typically spring or early summer.
• Repotting process: Carefully remove the plant from its old pot, shake off excess soil, and place it in a new pot with fresh soil.

With a bit of care, your succulent will thrive in its new home.
