How to Fix Calcium Deficiency in Plants

Extreme exhaustion, which includes a lack of energy and a general sense of sluggishness, can be brought on by low calcium levels. Insomnia may result from it as well. Along with fatigue, a calcium shortage can also cause lightheadedness, vertigo, and brain fog, which impairs concentration and causes confusion and forgetfulness.

Since plants absorb nutrients more effectively through their leaves than their roots, commercial foliar calcium sprays provide the quickest treatment for acute calcium insufficiency. It is frequently used to treat problems with container plants, particularly for seedlings and transplants.

Calcium deficiency in plants can occur for several reasons. Some of these causes are due to low transpiration rates and overwatering. Others are related to low pH. There are several ways to fix calcium deficiency in plants. To start, you can use Gypsum or Calcium-containing products.

Low Transpiration Rates

Calcium deficiency is a common plant disease; its symptoms include low transpiration rates. Low transpiration rates are caused by reduced evaporation, which leads to less water movement through the xylem. Other factors that can reduce transpiration rates include high humidity and cold temperatures. Therefore, understanding the importance of calcium in plants and the role of transpiration in plant growth and health is essential.

Calcium is a critical nutrient that is essential for healthy plant growth. It is the main force that moves calcium through the plants, so that low transpiration rates can result in calcium deficiency in lettuce. However, calcium is only present in the leaves when water moves through the plant. Therefore, most calcium deficiency in greenhouse plants is caused by environmental conditions, not nutrient deficiencies in the soil.

One common symptom of calcium deficiency is leaf deformity. This can cause the leaves to develop cupped or “tip burn.” In addition, a calcium deficiency can lead to decreased flower and fruit development. The result can be a crop that has poor yield or poor quality.


Gypsum is a highly effective mineral for fixing plant calcium deficiencies. It is a non-toxic compound that can be added to the soil. It also maintains the soil’s pH level. It can be used as a fertilizer. Alternatively, you can add eggshell calcium to your soil. Eggshell calcium is a good source of calcium for most types of plants. Store eggshell calcium in an empty container for a few days before adding them to the soil.

The best way to determine whether your soil needs gypsum is to do a soil test. First, mix a small amount of soil with 1/2 ounce of distilled water. Next, place this mixture in a glass jar about two-thirds full. Leave it for two hours. If the solution remains cloudy, your soil may be deficient in calcium.

Another way gypsum can help fix calcium deficiency in plants is by improving the soil’s pH. The mineral helps clay particles flocculate so they are not stuck together. This is helpful for crops that need to grow in soils with high pH. However, you should consult an agronomist before applying gypsum to your soil.

Calcium-Containing Products

Calcium is a vital nutrient for plants. Adding supplements to the soil can differentiate between healthy and unhealthy plants. Calcium-containing products help plants absorb nutrients more efficiently through the leaves. In addition, calcium-containing products can boost soil pH levels. One of the most effective calcium boosters is lime, which can be applied as a soil amendment.

Calcium-deficient plants often grow slowly. You can determine if your plants have a calcium shortage by testing the soil. In addition to calcium-containing fertilizer, you can add organic matter to the soil, such as bone meal, dolomite lime, eggshells, and gypsum.

It may affect calcium absorption if your soil has low pH or is humid. You can use fans to increase the amount of airflow. To determine the correct amount of calcium needed for your plants, you can test the soil’s pH level. The pH level will determine which calcium supplement products are best for your plants.

Moreover, plant-based products have higher bioavailability than dairy products. For example, 1 cup of cooked bok choy contains 160 mg calcium. This food also contains protein, fiber, and vitamins. As a result, it can improve your plants’ health and even protect them from various diseases.


Overwatering is one of the plants’ most common causes of calcium deficiency, but there are ways to fix the problem. The key is to properly water plants regularly. This prevents the soil from becoming too wet and prevents over-watering from affecting plant growth. If you notice that your plants are not taking in enough calcium, you should try a fertilizer containing calcium.

Overwatering can have the same effects on plants as calcium deficiency, including yellowing leaves, brown spots, and curling leaf edges. However, you can distinguish an over-watered plant from a calcium-deficient one by looking at the texture of its leaves. For example, if the leaves look spongy and limp, they are overwatered. Similarly, if the lower leaves have brown scaly spots, they are calcium-deficient.

In addition to adding extra water, you can also use a bone-meal supplement to help your plants absorb calcium. However, the pH of the nutrient solution should not be too acidic to allow the plants to absorb it properly. When your plants are experiencing symptoms of calcium deficiency, they will wilt and die. While it will take time to cure this condition, the following remedies will help you fix calcium-deficient plants.

‘Bitter Pit’

One of the essential nutrients for plants is calcium. Deficiencies in calcium can lead to stunted and deformed growth. A lack of calcium can occur for various reasons, including environmental factors like poor soil. By treating the soil correctly, calcium deficiency can be prevented.

The symptoms of a calcium deficiency are yellow leaves, brown patches, and curling leaf edges. Observe its leaves to tell whether your plant is suffering from a calcium deficiency. They’re likely overwatered if they’re soggy and the edges are crispy. In extreme cases, they’ll have brown spots and necrotic leaves.

In addition to adding more calcium to the soil, changing the watering schedule can also help. Soil pH should be neutral to encourage calcium uptake. The pH level should be between 6.5 and 9.5. If it’s outside this range, treat the soil with a neutralizing agent such as sulfur or lime. You can also supplement water with a calcium-rich fertilizer.

If the soil is too acidic, calcium deficiency flushing will help your plants take up the calcium in the soil. This will also restore the pH balance. A pH level of 6.5 is the ideal range for most plants.

Low Cation Exchange Capacity

Cation exchange capacity (CEC) is the capacity of a growing medium to exchange one cation for another. The measurement is usually expressed in milliequivalents (meq) per kilogram of soil or 100 g. There are several methods for calculating CEC.

The cation exchange capacity of soil is an essential factor for plant health. Many soils leach nutrients more quickly than others. Some soils have low cation exchange capacity, and turf crops will not grow well on them. The cation exchange capacity directly affects the soil’s fertility and the plants’ health.

Increasing the CEC of soil will help plants fix calcium deficiency. Plants need calcium and magnesium in a balanced ratio to grow. In soil with low CEC, the cations are more easily removed from the soil and leached into the growing medium.

Low cation exchange capacity is a common problem, resulting in plant calcium deficiency. Low-Ca plants can exhibit symptoms such as chlorosis on new leaves, necrosis along leaf edges, and even death of leaf buds. A low-Ca condition will also inhibit root growth and stunt plant growth.

Vitamin D Deficiency

Vitamin D deficiency has been linked to various health conditions, including increased risks for cancer, hypertension, cardiovascular disease, and autoimmune disorders. It is also linked to mood disorders and impaired brain function. In addition, the body must have enough vitamin D to produce healthy hormones and to repair and maintain tissue. Therefore, eating foods high in vitamin D, such as fish and eggs, is essential.

Vitamin D levels in humans have been associated with prostate cancer, and sun exposure has been shown to reduce the risk. However, prospective cohort studies have found little to no relationship between vitamin D status and the risk of breast cancer. Nevertheless, one large meta-analysis of 14 prospective studies found no statistically significant association between higher serum vitamin D levels and cancer mortality in both men and women.

No studies link low vitamin D levels in pregnant women with higher rates of autoimmune disease. However, vitamin D supplementation during pregnancy helps ensure adequate vitamin D levels.
