In this article, we will explore some of the plants that are well-suited to alkaline soil
What is Alkaline Soil?
Alkaline soil has a pH level above 7 This type of soil is common in arid and semi-arid regions, as well as in areas with high levels of limestone in the soil. While some plants thrive in alkaline soil, others may struggle to grow in these conditions.
Alkaline soil is characterized by a pH level higher than 7.3. The pH scale ranges from 0-14, with each number representing a different level of acidity or alkalinity. A pH level of 7 is considered neutral and neither acidic nor basic (alkaline).
5 Examples of Plants that Like Alkaline Soil
Now that I briefly explained what alkaline soil is, let’s look at examples of plants that thrive in Alkaline soil.
1. Rosemary:
Rosemary is a perennial herb that can grow up to 4 feet tall. It has aromatic leaves and flowers, which are used for culinary purposes as well as for their medicinal properties.
Rosemary thrives in hot and dry environments with poor soil drainage. The plant prefers full sun but can also tolerate partial shade.
These herbs are known to do well in soil that is above 7.3 ph levels.
2. Lavender
Lavender is a fragrant herb that is popular for its beautiful purple flowers and calming scent. It is also a tough and versatile plant that can tolerate a range of soil conditions.
Lavender prefers well-draining soil with a pH level between 6 and 8. Alkaline soil is generally within this range, making it a good choice for growing lavender. One of the key benefits of growing lavender in alkaline soil is that it is less prone to certain diseases and pests.
For example, lavender is resistant to root rot, which is a common problem in soil that is too acidic. Additionally, lavender is resistant to pests such as aphids and mites, which can be attracted to plants growing in acidic soil.
3. Hydrangea
Hydrangea is a popular flowering shrub that can grow up to 3 feet tall. The plant has large, showy clusters of flowers that bloom in mid-summer and fall.
There are many varieties of hydrangea available, including oak leaf and lace cap. Oak leaf varieties produce leaves that have an oak-like shape while lacecap varieties have rounded flower heads.
4. Lilac
Lilac is a popular flowering shrub that is known for its beautiful, fragrant blooms. It is a hardy plant that can tolerate a range of soil conditions, but it prefers slightly acidic soil with a pH level between 6.5 and 7.0. In alkaline soil, lilac may struggle to absorb nutrients and may produce fewer flowers.
Like hydrangea, there are a few strategies you can try to improve the chances of growing lilac in alkaline soil. Adding organic matter to the soil can help lower the pH level and improve the soil structure.
You can also try using an acidifying fertilizer, such as sulfur, to help balance the pH level of the soil. It is also a good idea to mulch around the base of the plant to help retain moisture and suppress weeds
5. Cabbage
Cabbages are a popular vegetable that many gardeners grow. However, the plants can be sensitive to soil pH levels. The ideal pH range for cabbage is between 6.0 and 7, due to its preference for slightly acidic soil.
In alkaline soil, cabbage may suffer from nutrient deficiencies and lower yields than it would in a more acidic environment. You can try adding compost or other organic matter to help improve the texture of your soil so that nutrients can better penetrate it
Final Thoughts
In conclusion, these are 5 examples of plants that grow on Acidic soil, there are plenty of other plants that do too. If you’re a gardener looking for some inspiration, these 5 plants are sure to be a great place to start!
