Caltrate is an external source of Calcium & vitamin D3 that doctors recommend to people for preventing osteoporosis (weak or brittle bones) and curing calcium deficiency. It is also a great source of vitamin D that helps the body to absorb calcium effectively.

Caltrate can play a crucial role in correcting the calcium and magnesium deficiencies in the soil and plants. To make a foliar spray, crush two tabs of Caltrate in a liter of water and spray it on the foliage of the plants when the sun is low. 

2. Nutrients for Indoor Plants

You can also add Caltrate to the soil as calcium helps strengthen cell walls and boost new growth. It also aids in root and pollen tube growth as well.

Crush 2-3 tabs, mix in the growing medium, and water well. 

3. Helps Plants to Form Healthier Fruits

Calcium plays a vital role in fruit and vegetable production in plants. If the soil does not have an adequate amount of calcium, it will prevent the uptake of nutrients in the fruits, causing them to grow smaller in size.

Adding Caltrate to the growing medium will significantly enhance the quality and size of the fruits. Add 3-4 crushed tabs in the growing medium once in 8-12 weeks for best results.

4. Prevent Stunted Growth in Plants

If the plants in your garden show signs of stunted growth, it might be due to calcium deficiency.

Calcium is taken up by roots from the soil and delivered to the shoot via the xylem. Symptoms of calcium deficiency first appear on younger leaves and tissues, where you can spot brown chlorotic spots developing along the margins, which eventually spread to unite in the center of the leaves. 

With its calcium supplement, Caltrate adds structural strength to the stems and aids in strengthening the cells, which makes the stems strong. 

Crush 3-4 tabs, mix it in water and use the solution to water the plants once in 4-6 weeks.

5. Get the Shine Back on Houseplants

As the University of Wisconsin states, blossom end rot is caused by a lack of calcium in the fruit. This lack of calcium may be due to low calcium levels in the soil. If you notice your tomatoes suffering from the same diseases, it would be great to use Caltrate to combat the problem.

Crush 4-6 tablets, make a fine powder, mix it with 2 liters of water and use it to water the plants once in 3-4 weeks. You can also use it as a foliar spray.

According to a report by Clemson University, calcium in Caltrate works in roses and petunias as much as it does in humans. It binds with materials in plant cell walls, making it more difficult for the fungus to penetrate and cause infection.

Spraying Caltrate solution on petunia flowers helps them increase tolerance to Botrytis infections.

Crush 4-6 tabs of Caltrate, make a fine powder, and add it to 2 liters of water. Use this solution to water these plants once a month.
