How to Properly Lime Your Tomato Plants

Apply 1 cup of hydrated lime for every 20 feet of the tomato row in order to raise soil ph to the required amount for tomato growth. Lime application frequency should be based on soil conditions and ph testing.

Tomatoes are warm-weathered and sun-loving plants popular in home gardens due to their ease of cultivation and abundant produce. However, successful tomato cultivation requires adequate attention to planting preparation, pest and disease management, and nutrient delivery. One key aspect of nutrient uptake is soil ph, which plays an essential role in plant growth, nutrient availability, and soil microbial activity. For tomato plants, the ideal soil ph level is slightly acidic, ranging between 6. 0 and 6. 8. Gardeners must, therefore, apply lime to lower acidic soil ph for successful tomato yields. But, how much lime to put around tomato plants? And, what other factors should gardeners keep in mind when applying lime? Keep reading to find out.

How to Properly Lime Your Tomato Plants


What Is Lime?

Lime is a type of mineral used in gardening to help with soil acidity balance. It also contains nutrients like calcium, magnesium, and potassium, all of which are essential for plant growth. There are different types of lime, such as dolomitic and agricultural lime, and each offers unique benefits.

Dolomitic is rich in magnesium, which aids in plant cell development. On the other hand, agricultural lime is made from crushed limestone and helps in neutralizing acidic soil. Lime is crucial for tomato plants, allowing them to grow healthier, bear more fruit and prevent blossom end rot.

Adding lime to the soil around your tomato plants can enhance their productivity and add essential nutrients to the soil.

Importance Of Ph Levels For Tomato Plants

Ph levels play an important role in the growth of tomato plants. The optimal ph level for tomato plants is around 6. 0 to 6. 8. If the ph level is too high or too low, it can affect the growth and yield of the plant.

Too high or too low ph levels can cause nutrient deficiencies and toxicity. For instance, if the ph level is too high, the plant may not be able to absorb nutrients like iron, manganese, and phosphorus. Similarly, if the ph level is too low, the plant may suffer from aluminum toxicity.

Therefore, it is essential to maintain the ph level of soil to ensure the healthy growth of tomato plants and a bountiful harvest.

Using Garden Lime on Tomatoes

Understanding Acidity In Soil

Soil acidity is a crucial factor that affects the growth of tomato plants. It refers to the level of hydrogen ions in the soil, which determines the ph level. When the ph level is too low or too high, the plants can’t access the necessary nutrients from the soil.

Soil acidity measuring methods include chemical soil tests, litmus paper, and ph meters. Soil ph can be adjusted by adding additional lime, which is a common soil amendment. As a general rule, 5-10 pounds of lime per 100 square feet can be added to bring ph levels up.

The amount of lime needed will depend on soil type, desired ph, and other factors. Therefore, it’s essential to measure soil acidity to determine the appropriate amount of lime to apply around tomato plants.

How Lime Helps Tomato Plants

Lime is crucial for tomato plants as it neutralizes soil acidity, boosting nutrient availability. In addition, it also enhances soil structure, ensuring that the tomato plants grow optimally. Without adequate lime, the tomato plants may not receive the necessary nutrients and may not thrive, affecting the yield.

The amount of lime to put around tomato plants varies depending on soil ph levels and type. To establish the right amount, get a soil test done to determine the ph level and amount of lime needed. Apply the right amount of lime around the tomato plants in a circular manner, about three to four inches away from the stem.

Consider adding a layer of compost over the lime to help enrich the soil further.

How Much Lime To Apply

Tomato plants can benefit from the addition of lime to the soil. The recommended amount of lime varies based on the ph level of the soil. Soil that is acidic requires more lime than alkaline soil. A general rule is to apply around 1/4 to 1/2 cup of lime per plant.

Factors such as rainfall can also affect the amount of lime needed. It’s best to conduct a soil test to determine the exact amount of lime needed. To apply lime, scatter it evenly around the base of the tomato plant, being careful not to let it come into direct contact with the plant.

Lime can be applied in the spring or fall for best results.


After reading this article, you now have a better understanding of how much lime to put around tomato plants. It is important to maintain the correct ph level in the soil to ensure that your tomato plants receive the nutrients they need to grow healthy and strong.

A ph level between 6. 0 to 7. 0 is ideal for tomato plants. By applying the correct amount of lime, you can also prevent blossom end rot and other common tomato plant diseases. Keep in mind that over-liming your soil can lead to other problems, so it is best to carefully follow the recommended guidelines.

Remember also to apply the lime at the right time – ideally, at least two months before planting. Using lime is just one aspect of tomato plant care, but it is a crucial one that should not be overlooked. Good luck with your tomato planting!
