Are you trying to grow fruit trees but dealing with alkaline soil? You’re not alone—and while it’s not the most ideal soil type for fruit trees, you still have options.
Alkaline soil, which has a pH above 7, can make it harder for certain fruit trees to absorb nutrients. But the good news is that some fruit trees are more tolerant of alkaline conditions than others. The key is choosing the right species and giving them the proper care.
Let’s help you turn your garden into a productive, fruit-bearing space—even with alkaline soil.Or, your fruit might not taste delicious.
What Causes Alkaline Soil?
Alkaline soil can be caused by the natural weathering of minerals or man-made sources such as pollution, softened water used for irrigation, and wet cooling towers. It can have pros and cons, such as making it possible to grow certain soil plants that won’t thrive in acidic soil but making it difficult to grow acid-loving plants and making nutrients less available.
Alkaline soil can be managed by adding organic matter to the soil to make it more acidic, adding fertilizer to supply any missing nutrients, and testing the soil regularly to ensure it is within the optimal range for the plants you are growing.
It’s also important to consider the soil’s climate and location, as alkaline soil is more common in hot places with lower rainfall. To ensure the soil stays at the optimal pH level for your plants, monitoring and adjusting the pH level as needed is important.
This can be done using a soil testing kit, which will give you the precise pH level of your soil. Additionally, it may be necessary to adjust the pH level by adding compost, sulfur, or lime.
Make Sure That You Have the Right Alkaline Soil
Before we get to the type of fruit trees you can plant in your alkaline soil, and you need to know what it is and its pH balance.
When using a soil tester, you will know exactly what type of soil you have. If you have acidy or alkaline soil, this is something that you need to test every time you are planting something in your garden. If the soil test shows a PH level below 7.0pH, then the soil is acidic.
When the soil is below 7.0pH, you have alkaline soil. We love this soil alkaline testing kit.
The Best Fruit Trees That You Can Grow in Alkaline Soil
By researching, you might find that fruit and vegetables there isn’t much you can plant in alkaline soil, especially if you want to plant fruit trees. However, these fruit trees will grow successfully in alkaline soil because they will tolerate high pH levels.
If you want to plant any one of these mentioned fruit trees, and the pH levels aren’t correct, you can add some nutrients that you can buy to make your soil alkaline soil with higher pH levels.
Apricot Trees
Apricot trees are among the best fruit trees for alkaline soil, thriving in conditions where the pH is above 6.0. In fact, they tend to perform better in slightly alkaline soil than in acidic soil, making them an excellent choice for gardeners working with higher pH levels.
However, while apricots can tolerate alkaline conditions, it’s important to monitor your soil’s pH. Ideally, keep it below 8.0 to ensure the tree can properly absorb nutrients. If the pH gets too high, nutrient uptake may be restricted, potentially affecting fruit quality and tree health.
To maintain optimal conditions:
Test your soil regularly to monitor pH levels
Add organic matter or sulfur-based soil amendments if the pH climbs above 8.0
Use a balanced fertilizer to support healthy growth and fruit production
By managing the soil carefully, you’ll help your apricot tree produce delicious, high-quality fruit and enjoy a long, healthy life in your garden.
Fig Trees
If you’re working with high pH (alkaline) soil, your options for fruit trees may seem limited—but fig trees (Ficus carica) are one of the few that truly thrive in these conditions.
Fig trees naturally prefer soil with a pH between 6.0 and 8.0, and in many cases, they grow even better as the pH climbs. Unlike many fruit trees that struggle to absorb nutrients in alkaline environments, fig trees remain healthy and productive, even when the soil is strongly alkaline.
Some key tips for growing fig trees in high pH soil:
Ensure the soil drains well; figs dislike soggy roots
Choose a sunny spot—they love full sun
Amend the soil with compost to improve structure and moisture retention
Water deeply but infrequently to encourage deep root growth
If your soil’s pH is consistently high and you’re looking for a low-maintenance, heat-tolerant tree with delicious fruit, figs are a reliable and rewarding choice.
Ensuring the fig tree gets enough water, sunlight, and the right feedings are essential for a correctly grown tree. A fig tree can die easily if you don’t take correct care of it.
Some Berries Varieties
If you love berries, then we have some good news for you. You will be able to plant a variety of berries in alkaline soil with a higher pH level than 7.0. But you need to be careful; not all berries prefer alkaline soil. Some prefer acidy soil and will die in soil that has a high pH level.
The berries that you can plant successfully will include:
- Alder-Leaved Serviceberry
- Black Sapote
- Blackberry
- Panama Berry
Guava
Guava trees are known for their versatility when it comes to soil conditions. While they generally prefer a pH just above 7.0, they can still grow successfully—and produce sweet, flavorful fruit—even in more alkaline soils. This adaptability makes them a great choice for gardeners working with less-than-ideal soil.
That said, guavas tend to perform best when given proper care, especially in challenging soil types. If you’re planting a guava tree in alkaline soil, it’s important to monitor the soil’s pH and avoid levels that are excessively high. Slightly amending the soil with organic matter can help improve conditions without making it overly acidic.
Before planting, keep in mind:
Guavas are temperature-sensitive and not suitable for colder climates. They thrive in warm, frost-free regions.
They require consistent watering and regular feeding—especially during the growing season—to ensure strong root development and fruit production.
Mulching around the base helps retain moisture and suppress weeds, while also providing slow-release nutrients.
If you’re willing to give your guava tree the care it needs, it can be a fruitful and rewarding addition to an alkaline-soil garden.
Citrus Fruit Trees
Citrus trees—including lemons, oranges, limes, and grapefruits—generally prefer soil with a pH slightly above 7.0, making them a suitable choice for alkaline or neutral soils. While they can tolerate clay-based soil, they do not thrive in salty or coastal soils, which can interfere with root function and overall health.
One of the reasons citrus trees are so popular among home gardeners is their ease of growth and high fruit yield during the season. With the right conditions, they grow into large, productive trees that offer both visual appeal and delicious fruit.
However, it’s important to remember that climate and weather play a critical role in their success. Citrus trees are sensitive to frost and cold temperatures, so they perform best in warm, subtropical, or Mediterranean climates. In cooler regions, container growing or frost protection may be necessary.
Tips for growing citrus trees in alkaline soil:
Ensure the soil drains well to prevent root rot
Apply balanced citrus fertilizer regularly, especially during the growing season
Water deeply and consistently
Mulch around the base to conserve moisture and regulate temperature
If you’re in the right climate and have slightly alkaline soil, citrus trees can be a delightfully rewarding addition to your garden.
Tips When Growing Fruit Trees in Alkaline Soil Successfully
- You need to make sure that you are testing the soil correctly. If you were planting fruit trees in alkaline soil and made a mistake with your testing and readings, you could be making a huge mistake.
- Planting trees and other plants in the wrong soil type will kill the tree and not grow successfully.
- If you are worried about getting the soil tested, you can always take a soil sample to a professional. Then, you will get a more accurate reading.
- Even if you plant your fruit trees in alkaline soil, you must remember that the trees still need feeding and the right temperature and climate to grow successfully.
Conclusion
Having alkaline soil in your backyard doesn’t mean that you will never be able to grow any fruit trees. It just means that you need to be careful about the type of tree you will plant. Most fruit and vegetable and fruits plants prefer lower pH levels, which means that it prefers acidy soil. But, the fruit trees we mentioned can also be planted in alkaline soil.
With all this information, you will know more about pH levels, fruit trees that can tolerate these levels, and other tips for growing fruit trees successfully.
