Best Calcium Fertilizer For Tomatoes

Calcium is an important nutrient for your tomato plants. It’s needed for the development of the plants’ cell walls, as well as for the production of chlorophyll. Calcium also helps with proper growth, which is why it’s important to add calcium to your soil when growing tomatoes.

The best calcium fertilizer for tomatoes is a water-soluble form of calcium called gypsum. It’s a good idea to add gypsum to your soil before planting, but if you don’t have time for that, you can use it at any time during the season.

Gypsum improves the soil structure by adding more air spaces between grains of sand or clay particles. This allows air and moisture more easily into the root zone where they are needed by plant roots. Gypsum also helps improve drainage and prevents compaction problems in sandy soils by acting as a binding agent between sand particles so they don’t fall apart as easily during rainstorms or heavy winds (which may happen during tomato plant growth).

Best Calcium Fertilizer For Tomatoes

The best calcium fertilizer for tomatoes is a great way to keep blossom-end rot from happening. While the actual cause of this fungus isn’t known, it is likely a result of poor uptake of calcium. Fortunately, there are several different ways to supply your plants with this essential mineral. Here are three options. Read on to learn more about each. To find out which one is best for your tomato plants, read on.


The best way to provide the perfect conditions for growing tomatoes is to add a bit of calcium to the soil. While calcium is necessary for healthy plant growth, it is not the only nutrient that tomatoes need. Gypsum is a great source of calcium, as well as other essential nutrients. When applied to the soil near the tomato plants, gypsum has many beneficial effects on the plants.

Apply gypsum around the tomato plants every year. If lime is not available, you can substitute it with calcium chloride. However, the resulting growth will be slow. In addition to providing calcium, gypsum also has a pH-neutral effect. In addition, lime can also be used in place of gypsum. Regardless of whether you choose to use gypsum or calcium chloride, it is important to remember that the former is more cost-effective.

A good way to determine whether gypsum is needed is to have your soil tested. You can obtain these results from a Cooperative Extension Service. Check for the pH level of the soil. You can see if it is alkaline or acidic by obtaining a test result. If your soil is alkaline, gypsum is not necessary. A pH-neutral test will give you a reliable indication of whether or not you need to add more calcium.

Wood ash

If you’re considering adding wood ashes to your garden, you should know that this type of compost contains many nutrients that tomato plants need to thrive. The nutrients may vary, depending on the type of wood you burn. Hardwood may have more than softwood, but either way, wood ash contains calcium, potassium, and magnesium. Calcium is important for tomato plants because it helps to prevent blossom end rot, which is common in soils lacking calcium.

When used as a soil fertilizer, wood ash is a great source of calcium. It can also contain a high amount of potassium, which may prevent yellow shoulders and blotchy tomatoes. Wood ash also has trace amounts of other nutrients, including magnesium. It is water-soluble and neutralizes soil acidity. The best part about wood ash is that it is completely safe for your garden.


The use of eggshells as a fertilizer for your tomato plants is an effective way to increase the amount of calcium and other minerals in your soil. The Permaculture Research Institute has used eggshells to rehabilitate the soil’s fertility. Eggshells contain calcium carbonate, and a combination of vinegar and eggshells can help your tomato plants grow healthy and strong. Vinegar breaks down the calcium carbonate in eggshells to water-soluble calcium acetate.

In addition to being a source of calcium, eggshells contain essential micronutrients for plants. They contain magnesium, calcium, iron, manganese, and calcium carbonate. The shells are also rich in trace minerals such as potassium, zinc, and selenium. Crushed eggshells are ineffective as a fertilizer, and they break down too slowly to be useful. If you want to use eggshells as a fertilizer for your tomato plants, you must crush the shells with a pestle or a rolling pin. Then, you can store the eggshell powder in jars and use it as a fertilizer on your plants.

To make the eggshell fertilizer, you need to wash the eggshells thoroughly. Put the shells into a plastic bag and crush them. Alternatively, you can use a blender to powder eggshells. This fertilizer is best placed around tomato plants and other fruits and vegetables. The eggs will also help to prevent blossom end rot, which is the cause of black patches on one end of your vegetable.

Gypsum is a natural source of calcium

If you’re trying to grow healthy tomatoes, you’re probably wondering how to add calcium to your soil. While you can buy a variety of plant-based calcium fertilizers at garden centers, you should avoid ammonia-based fertilizers. Ammonia-based fertilizers are often harmful to soil and tend to absorb calcium. However, gypsum is a natural source of calcium for tomatoes and can provide these plants with other essential nutrients as well.

To make a simple solution, simply mix gypsum with water in a spray bottle. Spray the mixture on the plant’s leaves and stems, and wait for it to work. Repeat this process at least three times per week. You should start spraying after the second set of flowers has bloomed. Be aware, however, that foliar sprays don’t penetrate the soil well and rarely get to the fruit.

Another natural source of calcium for tomatoes is eggshells. While molasses is a good source of calcium, it’s not the best choice if the ground is too salty. For that reason, garden centers sell fertilizers with high calcium content, but these products are mostly for pH control. And, of course, they’re also great for preparing compost. When choosing calcium fertilizer for your tomatoes, you should consider the type of soil you have in your garden.

Gypsum is a soil conditioner

A good soil conditioner for tomatoes is gypsum. This mineral is known to improve the soil’s pH level and supply sulfur and calcium to plants. In particular, gypsum helps prevent blossom end rot in tomatoes and peppers. Symptoms of a calcium deficiency include premature shedding of blossoms, dead buds, weak stems, and abnormally dark green leaves. The most effective dose of gypsum to apply is 20 pounds per 100 square feet and tilled into the soil. A small amount of gypsum per plant is applied when tomatoes begin to bloom.

Some studies indicate that gypsum can enhance the response of a plant to fertilizers. Some studies have shown that gypsum increases the availability of iron and zinc, which are essential for plant growth. It also helps keep clay particles off roots, tubers, and bulbs. When used in combination with water-soluble polymers, gypsum enhances the effectiveness of fertilizers and can even help prevent soil compaction.

Gypsum is a good source of calcium

If you are trying to grow tomatoes, you should consider adding Gypsum to the soil. This nutrient is a secondary nutrient that plants need. It is a balancing element in the plant’s diet, helping protect them from low pH levels, high nutrient levels, and heavy metal contamination. It is also good for the structure of the soil. It is widely available and is a good source of calcium for tomatoes.

If you are worried about the acidity of your soil, gypsum can be helpful for tomatoes. This mineral is not only a good source of calcium, it also provides the other nutrients they need to grow. When used properly, gypsum can be spread near tomato plants and watered in to promote absorption. While tomatoes do not require a lot of calcium, they will grow better if you add it to the soil.

Too much salt can harm the plant’s roots. Excess salt can inhibit the production of chlorophyll, which is essential for photosynthesis. If the plant is suffering from excess salt, the leaves and flowers will be brown instead of green. Gypsum can replace the lost salt in the soil and encourage new growth. But remember that it will take longer to reap the rewards of your efforts.

Gypsum is the best source of calcium for tomato plants

If your soil is low in calcium, you may need to add more gypsum to your soil. Calcium sulfate, or gypsum, is a natural source of calcium. Taking a soil pH test can help you determine whether you need to add more. It is easily absorbed by plants and doesn’t change the soil’s acidity. You can purchase gypsum at your local home improvement or gardening center. You should apply it near the tomato plants to help the soil absorb the calcium. Watering is also necessary to encourage the absorption of gypsum.

Other common fertilizers are rich in calcium. Bat guano, soft rock phosphate, and kelp are all-natural sources of calcium. You can also purchase special fertilizers for tomatoes that contain calcium. Apply the fertilizer to the soil by tilling it and do not disturb the roots of the tomato plants. Apply half a cup of 8-8-8 fertilizer to the soil. Sprinkle the mixture around the tomato plants every two to three weeks.

Other calcium sources

Tomatoes require calcium from the soil for good quality fruit. In addition to calcium nitrate, other sources of calcium for plants are limestone and shellfish. Calcium is needed to maintain a firm fruit structure and increase sugar content, but there are other sources of calcium for tomatoes. Avoid using ammonium-based fertilizers, which decrease the pH of the soil and cause BER. Boost the calcium content of the soil with these other natural sources.

Another great source of calcium for tomato plants is soluble fertilizer. Many common fertilizers are calcium-rich, including bat guano and soft rock phosphate. Calcium-containing fertilizers are available in granular or liquid form. It is important to water tomatoes deeply since shallow watering will negatively affect growth. Soak the roots of the plant before applying fertilizer. Another option is using a half cup of 8-8-8 fertilizer in the soil.

When planting your tomatoes, remember to add calcium to the soil as it is important for proper growth and fruit development. This mineral aids in building strong roots, developing healthy flowers, and producing seeds. Tomato plants can absorb calcium from the soil naturally, but a calcium-deficient soil can result in stunted growth and poor fruit production. You can also add calcium fertilizer as the tomatoes grow and develop. Soil pH can also interfere with calcium absorption, so it is important to choose the right kind of soil and fertilizer for your plants.
