Many plants do not thrive in acidic soil, which can make it difficult for them to absorb essential nutrients.
Some examples of plants that do not tolerate acidic soil include hydrangeas, gardenias, and azaleas.
These plants require a soil pH of around 6.5 to 7.0 to thrive, so if the soil in your garden is more acidic, consider growing plants that are more tolerant of acidic conditions.
What plants do not like acidic soil?
plants which prefer soil with a pH of 6.5 to 7.5. If your soil is too acidic, you can add lime to raise the pH. However, it is important to test your soil first to determine the correct amount of lime to add. Too much lime can also be harmful to plants.
Some plants do not thrive in acidic soil, including:
- Hydrangeas: These popular flowering shrubs prefer slightly alkaline soil, with a pH of 6.5 to 7.5. In too acidic soil, their leaves may turn yellow, and they may not produce as many flowers.
- Gardenias: These fragrant shrubs also prefer slightly alkaline soil, with a pH between 6.0 and 6.5. In too acidic soil, they may experience iron deficiency, which can cause their leaves to turn yellow.
- Rhododendrons: These beautiful flowering shrubs are sensitive to acidic soil, with a preferred pH between 5.0 and 5.5. In too acidic soil, they may experience iron deficiency and stunted growth.
- Azaleas: These colorful flowering shrubs are closely related to rhododendrons and have similar soil preferences. They also prefer slightly acidic soil with a pH between 5.0 and 5.5. In too acidic soil, they may experience iron deficiency and stunted growth.
- Ficus: These popular indoor plants, also known as fig trees, prefer slightly acidic soil, with a pH between 6.0 and 6.5. In too acidic soil, they may experience nutrient deficiencies and stunted growth.
It is essential to match the soil pH to the specific needs of the plants you are growing in your garden.
Table of Plants Do Not Like Acidic Soil With pH Range
| Plant | Preferred pH Range |
|---|---|
| Hydrangeas | 6.5 to 7.5 |
| Gardenias | 6.0 to 6.5 |
| Rhododendrons | 5.0 to 5.5 |
| Azaleas | 5.0 to 5.5 |
| Ficus | 6.0 to 6.5 |
What is acidic soil?
Acidic soil has a pH level of less than 7.0 on the pH scale. This means that the soil is rich in hydrogen ions, which give it a sour or acidic taste.
why do some plants not like it?
Some plants, such as hydrangeas, gardenias, and azaleas, do not tolerate acidic soil well because it can make it difficult for them to absorb essential nutrients.
These plants require a soil pH of around 6.5 to 7.0 to thrive, so if the soil in your garden is more acidic, you may want to consider growing plants that are more tolerant of acidic conditions.

What are some common plants that thrive in acidic soil?
Many plants thrive in acidic soil. Some common examples include azaleas, rhododendrons, blueberries, potatoes, and hollies.
These plants have adapted to grow in soil with a low pH, which means it is more acidic.
In general, acidic soil is typical in regions with high amounts of rainfall, such as the United States Pacific Northwest.
Acidic soil can also be found in areas with many pine trees since the needles from these trees can make the soil more acidic over time.
How does it affect plants?
- Acidic soil can cause nutrient deficiencies in plants, leading to stunted growth and other problems.
- Alkaline soil can also be harmful to plants, causing toxic levels of certain nutrients.
- Most plants grow best in soil with a neutral pH of around 7.0.
- Testing and adjusting the pH of the soil is essential for ensuring the health and growth of plants.
FAQ
What are the symptoms of plant damage from acidic soil?
The symptoms of plant damage from an acidic soil can vary depending on the acidity’s severity and the plant type.
Some common symptoms include:
- Stunted growth
- Yellowing of leaves
- Wilting or drooping of leaves
- Loss of leaves
- Poor fruit or flower production
- Death of the plant
How can I adjust the pH of my soil to make it less acidic?
To adjust the pH of the soil to make it less acidic, you can add lime, use compost, plant acid-loving plants, or use sulfur.
These methods can help neutralize the acidity in the soil and create a more balanced environment for plants to grow.
Are there any plants that cannot grow in acidic soil at all?
Most plants can grow in slightly acidic soil, but some plants may not be able to tolerate highly acidic soils.
For example, plants that prefer alkaline soil, such as lilacs and gardenias, may struggle to grow in acidic soil.
Plants that cannot tolerate acidic soil will show signs of stress, such as stunted growth, yellowing leaves, and poor flower or fruit production.
If you are unsure whether a particular plant can tolerate acidic soil, it is a good idea to do some research or consult a gardening expert before planting it.
