5 Common Issues When Growing Plants and How To Fix Them

5 Common Issues When Growing Plants and How To Fix Them

Have you ever felt like your garden needed a visit from a plant doctor? Gardening can seem like a breeze when your green buddies are thriving. But when your plant starts wilting or yellowing, it's like sounding an alarm that something's not right.

Understanding what's going wrong with your plants can feel like a puzzle, especially if you're new to the gardening game. However, getting to grips with a few common gardening hurdles can make all the difference. It's all about spotting the signs early and knowing the right fix.

Let's dig into some typical plant predicaments and how you can turn your garden's luck around, making it a lush, flourishing haven once again.

Troubleshooting Common Issues


1. Light Power and Currents Problems

1. Light Power and Currents Problems

Plants need light -- it's essential for them to thrive. However, understanding their light requirements is more complicated than just providing them with as much light as possible. Here's a simple guide to help:

  • Understand Light Needs: Not all plants are the same. Some need just a little light; others might require direct sunlight. Know your plant's needs.


Beware of Too Much Light:

  1. Duration: Too many hours of light can harm some plants by disrupting their natural growth cycles.
  2. Intensity: Very bright, direct light can be too harsh for many plants, leading to damage or dehydration.
  • Causes of Excess Light: Sometimes, we unknowingly place plants in spots where they get too much light. Other times, misinformed decisions lead to excess exposure. Knowing what your plant needs can help avoid these situations.


Signs of Too Much Light:

  • Leaves drooping or showing changes like pale or brown spots, while the veins may remain green.
  • Dry patches on leaves or browning tips.
  • Younger plants may wilt, and leaves may curl downward, reducing overall growth.



  • Move the plant to a suitable location, considering seasonal changes in light intensity.
  • Know the light requirements of your plants to ensure they're in the best spot from the beginning.
  • Choose plants based on the available light in your home to prevent future issues.


By taking these points into account, you can ensure your plants receive the right amount of light they need to be healthy and beautiful.

2. Nutrient Deficiencies

2. Nutrient Deficiencies

Just like people, plants need a balanced diet to grow strong and healthy. When they don't get the right nutrients, they start showing signs like discoloration or not growing as much as they should. It's kind of like when you feel a bit off because you haven't been eating well.

Causes and Solutions

  • Signs to Look Out For: Keep an eye out for leaves turning yellow or brown and if your plant isn’t growing as much as it used to. These can be hints that your plant buddy is missing some vital nutrients.
  • The Fix: Sure, adding some fertilizer sounds like an easy fix, and sometimes, it is! But it's not just about adding more; it’s about adding the right kind. Different plants need different things. You might need to do a little detective work or ask for advice at your local garden center to figure out exactly what your plant needs.
  • Complicated Diets: Remember, some plants are picky eaters with complicated diets. They need a special mix of nutrients. If your go-to fertilizer isn’t helping, it might be time to look into specialized options that match your plant's specific needs.


3. Heat Stress

3. Heat Stress

When it gets super hot, plants can really struggle, kind of like how we feel during a scorching summer day. If plants get too much sun and heat, they can't handle it well. They need a cool spot, just like we do! Most plants like it best when it's between 68 and 86 degrees Fahrenheit. If it gets hotter than that, either in the air or the ground, plants start to have a hard time.

Here's a simple guide on how to tackle these signs:

  • Leaves Rolling Up: Move your plant to a shadier spot or create some shelter to protect it from the intense heat. This will help it conserve water and stay cooler.
  • Wilting: Ensure the plant is well-watered early in the morning or late in the evening to avoid evaporation. If the plant recovers in cooler temperatures, it’s a sign it was just too warm.
  • Dry Edges on Leaves: Increase the humidity around your plant. This can be done by misting the leaves or placing a water tray nearby. Also, keep your plant in indirect light where it won’t dry out as quickly.
  • Ozone Damage: If the air quality is poor, try to move your plant indoors or to a cleaner area. Using air-purifying plants around your garden can also help improve the local air quality.
  • Flowers or Fruits Dropping Off: Regularly water and mulch around the base of the plant to keep the roots cool and moist. This helps the plant to focus on maintaining its blooms and fruits even in high temperatures.
  • Bolting: Provide ample water and shade to cool down the plants. Sometimes, planting a little later in the season can help avoid bolting triggered by early heat waves.
  • Sunscald: Use nets or shades to protect exposed fruits from the direct sun, especially during the peak hours between 10 AM and 4 PM.
  • Blossom-End Rot: Ensure consistent watering and consider using calcium-rich mulch-like crushed eggshells around the base of the plant to prevent the rot and protect it from excessive heat.


By adopting these strategies, you can alleviate the effects of heat stress on your plants, helping them to thrive even during the warmest months.

4. Pest and Fungus Investigation

4. Pest and Fungus Investigation

Controlling pests in your garden starts with knowing who's causing the trouble. Here's a quick guide to help you identify and deal with common pests safely and effectively:

  • Identify the Pest: Properly identifying the pest is the first step. This helps determine the best way to manage them.
  • Know the Stage: Understand at what developmental stage the pest is best managed.
  • Choose Your Tools Wisely: Non-chemical tools can be very effective and include:
  • Using a stream of water to remove insects.
  • Wiping pests off with a cloth.
  • Picking pests off the plant by hand.
  • For More Help: If you're unsure or need more information, especially about chemical control options, reach out to your county Extension office.


Common Houseplant Insects and Their Damage





Tiny green, brown, or black insects usually found on the undersides of leaves.

Causes stunted plant growth and curled or distorted foliage due to feeding.


Scale insects with a white cottony appearance found on stems, undersides of foliage, and nodes.

Feeding results in stunted plant growth.


Tiny, light-colored arachnids (not insects).

Produce webbing on foliage and stems, with feeding resulting in distorted yellowish foliage.


Oval or round, brown insects located on stems and leaves.

Suck plant juices, leading to poor or stunted plant growth.


Extremely tiny, adults are light tan to dark brown; appear white when young.

Feed on foliage and flowers, causing distortion and discoloration.


Small, white, gnat-like insects.

Feed on foliage and flowers, causing distortion and discoloration.


By taking these points into account, you can ensure your plants receive the right amount of light they need to be healthy and beautiful.

5. Light Burn and Sunburn

5. Light Burn and Sunburn

Plants love the sun, but just like us, too much of it can hurt them. It's easy to think more sun equals happier plants, but that's not always the case. It's natural for older leaves to turn yellow and drop, but when your plant looks more yellow than green, it's time to act. Here's how:

Causes and Solutions

Low Sunlight

Check if your plant's too cold. Plants can get chilly, too, especially near drafty windows or doors. Move your plant to a happier spot where it can bask in adequate sunlight and wave goodbye to those chills.

Excessive Sunlight

Sunlight is good, but too much can overwhelm your plant, turning leaves yellow. Think of it as a sunburn. Move your plant to a place with more shade to protect it from the harsh rays.

Low Light

If the issue is not enough light, the solution is simple - give your plant more light. Move it to a brighter spot where it can enjoy the sunlight it needs to thrive.

Frequently Asked Questions


How do you solve plant problems?

To tackle plant problems effectively, always clean up fallen leaves and other debris around your plants to keep the area tidy and disease-free. When watering, aim right at the base to avoid creating damp conditions that foster fungus. Keep plants spaced well apart to ensure they get enough air, and if a plant is really sick, it might be best to remove it completely to protect the others.

What are 4 factors that affect plant growth and how to deal with them?

All plants, no matter if they're in the ocean or a desert, need four basic things to grow: light, water, nutrients, and air. One of the most crucial factors for a plant's growth is light. It's not about how warm the light is, but the energy it carries that plants use to make food through photosynthesis.

How can we improve plant growth?

To boost plant growth, ensure they receive the right mix of water, light, air, and soil nutrients. It's also essential to keep them in the perfect temperature and show them a little love and care. These basic elements work together to help your plants thrive.

How do you fix root rot?

Root rot needs to be dealt with quickly. Start by removing the plant from its pot and shake off as much soil as you can. Then, rinse the roots gently with lukewarm water and cut away any roots that look dead or rotten using clean secateurs. Don't forget to disinfect the pot before putting the plant back in with fresh compost.

How do you save an unhealthy plant?

To save a struggling plant, sometimes all it needs is a fresh start. If it hasn't reached the point of no return, or its roots are peeking out from the pot, gently shake off the old soil, trim away any dead or slimy roots, and give it a new home with fresh potting soil.

Can you fix a dying plant?

To bring a dying plant back to life, try soaking it in water for a few hours, then stick to a consistent watering schedule using the same amount of water. If many leaves have turned brown, it's a good idea to remove them, as they won't recover.

The Takeaway

The key to keeping your plants healthy and beautiful is understanding their needs and giving them the right care. Whether it's dealing with pests, making sure they have the right amount of light, or solving common problems like root rot, every plant deserves a little TLC to thrive. Remember, plants are like people. Each one is unique and has its own requirements for a happy and healthy life.
