Lavender Yellowing? Here’s What You Should Do Immediately

Many gardeners have experienced lavender yellowing at some point. This problem can cause a lot of worry, as it can make plants look unhealthy and unsightly. 

Lavender yellowing is a common problem that can be caused by a variety of factors. It’s important to understand the causes of this problem so you can take steps to solve it.

There are several things you can do to prevent or fix lavender yellowing. By following these tips, you’ll be able to keep your plants looking healthy and beautiful.

Lavender yellowing: Top causes and solution

High Humidity:

One of the most common reasons for lavender yellowing is high humidity. Lavender plants prefer low humidity, so if the air is too moist, it may cause the leaves of your lavender plant to yellow.

To combat this problem, make sure that your lavender plant is in an area with good air flow. This will help to keep the surrounding air dry, reducing the risk of humidity-related yellowing.

Solution: 

If your lavender plant is experiencing yellowing due to high humidity, there are several steps you can take to solve the problem.

  • One of the most effective solutions is to simply move your plant to an area with lower humidity levels. If this is not possible, you can try increasing air circulation and ventilation in the area where your plant is located.
  • Put your plant in a sunny area to ensure there is no humidity

Root Rot Due To Overwatering 

It is relatively easy to grow and does not require a lot of water. You can water it as less as twice a week for a grown outdoor plant. However, overwatering can cause root rot, which will lead to yellowing leaves and even death of the plant.

To prevent lavender yellowing due to overwatering, be sure to check the soil for moisture before watering your plants. Generally speaking, if you are able to stick your fingers into the soil up to your first knuckle, they do not need water.

If the leaves on your plant begin to turn yellow or drop off, then you may be overwatering your lavender. If this is the case, it’s important to stop watering completely and allow the soil to dry out completely before resuming regular watering patterns.

Solution to root rot: 

One way to save a yellowing lavender plant with root rot is to repot it in dry, well-drained soil.

Start by gently removing the plant from its current pot.

Next, inspect the roots and trim away any that are black or mushy. It is important to be thorough; even a small amount of rot can spread quickly.

Once the roots have been trimmed, replant the lavender in a pot with fresh, dry soil. Be sure to water sparingly and only when the soil is completely dry; too much water can lead to new problems. With proper care, a lavender plant that has been affected by root rot can be successfully saved.

When you repot them, ensure that

  • Soil is porous and sandy (for example, 30% sand/gravel and 70% soil): This will allow the soil to dry out easily and prevent root rot.
  • There are proper drainage holes in the pot
  • Reducing water frequency: If you find that your lavender plants are always wet, it may be a good idea to reduce the frequency with which you water them.

Lavendar Turning Yellow Due to Disease or Pests

Lavender plants are relatively resistant to disease and pests, but they can still be susceptible to problems. Common diseases that affect lavender include powdery mildew and root rot.

Powdery mildew is a white or gray powdery fungus that appears on the leaves of affected plants. This disease is most often caused  by dry or hot weather and improper watering habits.

There are other pests and diseases as well.

Sometimes, because of the root rot or overwatering, there is fungal problems.

When soil becomes too wet, it can create a favorable environment for pathogens like fungi and bacteria to grow and thrive.

In addition, blocked drainage areas in the soil can lead to even more moisture build-up and increased risk of plant diseases.

Solution:  

To prevent disease and pest problems with your lavender plants, be sure to provide them with proper care.

For example, make sure that

  • you are watering them correctly (not too much or too little),
  • using a well-draining soil mix, and
  • providing proper sunlight and
  • air circulation for the plant.

If you notice signs of disease or pests on your plants, it’s important to address the problem right away. You may need to use a fungicide or pesticide specific to the cause of the issue in order to prevent damage and protect your plant.

It is also important to be aware of potential risks for diseases in your geographic area, such as fungal or bacterial diseases that are common in humid or wet climates.

Besides this, you should also

  • Keep the infected plants away from healthy plants
  • Dispose off any infected material properly to avoid spread of infections 

Adding Too Many Nutrients Through Fertilization:

The one thing you need to know that lavender are native to the Mediterranea which means,  they are used to sandy, lean, poor soil.

Lavender plant needs minimum nutrients, and  they are quite tolerant of poor soils. In fact, they actually prefer lean soils that are not too rich in nutrients.

However, if the soil is too rich in nutrients, it can cause the plant to produce more leaves and fewer flowers. In addition, too much nitrogen in the soil can cause the leaves to turn yellow (and sometimes may cause the lavender plant to look leggy).

That means, fertilization can  actually be detrimental to your lavender plants.

To prevent this problem, it’s important to take care when fertilizing your plants.

You should only provide the plant with a small amount of fertilizer, and if possible, choose a fertilizer that is low in nitrogen. Additionally, you should avoid overfertilizing or using too much organic matter in the soil, as this can also lead to nutrient build-up.

Solution:  

To prevent nutrient problems with your lavender plant, it’s important to give them the right care. For example, you should avoid overfeeding or over-fertilization: This can lead to nutrient build-up and cause the leaves of your plants to turn yellow.

  1. Use a fertilizer that is low in nitrogen: This will help to prevent the leaves from turning yellow.

Only use a small amount of fertilizer: Too much fertilizer can be detrimental to your plant.

And finally, make sure that you are using well-draining soil: This will help to prevent nutrient build-up and ensure that your plant gets the nutrients it needs.

2. Repot your lavender: If the damage is done, you can repotting your lavender. If you notice signs of yellowing or other nutrient problems in your lavender plants, it may be a good idea to repot them with new soil mix.

This will help to ensure that they are getting the right nutrients and proper drainage in their soil,  preventing issues like yellowing leaves and root rot.

To repot your lavender plant, you will need a pot at least 2 inches larger in diameter than the original pot, new soil mix, and a clean gardening trowel.

First, loosen up the old soil with your hands or a garden fork, being careful not to damage the roots of your plant. Then, transfer the plant to its new pot and add fresh soil mix around the roots, tamping it down lightly with your hands.

Finally, water your plant well and place it in a sunny location.

Unsuitable Pot or Container Choice:

If your lavender plant is showing signs of yellowing or other nutrient problems, it may be a good idea to repot the plant using different container.

This will ensure that the plant has proper drainage and is not overfed with nutrients.

To begin with, you should plant your lavender in a big enough pot with well-draining soil. It should also be wide and deep.

If you don’t use a wide and deep container,  the roots of your plant may become overgrown or even rot due to oversaturation of the soil.

Solution: 

When it comes to growing lavender, picking the right pot is essential for ensuring your plants flourish. A good starting point is to choose a pot that is noticeably wider and deeper than what you think you need. 

This allows for optimal root growth and prevents water from stagnating around your plants. In addition, look for pots with multiple drainage holes at the bottom to allow excess water to flow out freely. 

With these considerations in mind, you can be sure that your lavender will thrive and produce gorgeous purple flowers year after year. So go ahead, pick the perfect home for your lavender plants today!

Unsuitable Soil pH + lack of proper Drainage:

Two other key factors to consider when growing lavender are soil pH and drainage. Lavender plants need well-draining soil and a pH level of 6.0 to 7.0 in order to thrive.

Remember that lavender plant needs minimum nutrients, and  they are quite tolerant of poor soils. In fact, they actually prefer lean soils that are not too rich in nutrients. 

However, if the soil is too rich in nutrients, it can cause the plant to produce more leaves and fewer flowers. In addition, too much nitrogen in the soil can cause the leaves to turn yellow.

Besides that, if the soil is too wet or doesn’t drain well, the roots of the plant can become overgrown or even rot. This will cause the plant to look wilted, stunt its growth, and lead to yellowing leaves.

Soil:

Lavender prefers soils with a pH of 6.5-7.0. Not acidic, but alkaline in nature.

You can increase the pH of the soil by adding wood ash or lime. Check the pH of the soil regularly to ensure you’re at the right numbers.

Drainage:

Additionally, the plant requires well-drained soil in order to prevent root rot.

You can achieve proper drainage by adding sand or gravel to your potting mix, or by planting your lavender in a raised bed.

The best way is to make a 30:50 or 50:50 soil

Solution:

  • Check for drainge in the pot
  • Check for the pH of the soil and adjust if necessary. If the soil is acidic, don’t plant your lavender in it.

Lavender Yellowing Due to Too Little Sunlight:

Finally, it is important to provide your lavender plant with plenty of sunlight. Not only does this help the plant produce more flowers, but it also helps prevent water stress and yellowing leaves.

To ensure that your lavender gets sufficient sunlight, place it in a spot where it will get at least 6-8 hours of direct sun per day.

If you live in an area with hot summers, it’s best to provide some afternoon shade to prevent the leaves from scorching.

Solution: 

Place your lavender plant in a sunny location where it will receive at least 6-8 hours of direct sunlight per day. If you live in an area with hot summers, provide some afternoon shade to prevent the leaves from scorching.

Some Kind of Stress:

Lavender plants are also susceptible to stress. This can be caused by a number of factors, including transplanting, hot weather, and pests or diseases.

When lavender is stressed, it may produce fewer flowers and the leaves can turn yellow.

Solution:

To reduce stress on your lavender plant, be sure to

  • Care for it as suggested in the article
  • Protect it from unwanted weather conditions and others
  • Examine your plants and soil in regular intervals
