PRODUCT POST: Lawn & Garden Plant Calcium

Calcean’s Lawn & Garden Plant Calcium is essential to large- and small-scale gardeners’ success, from backyard gardens to flowerpots. It can also be ordered in bulk (SandyCal) for large-scale crop fields (ask us how!).

Lawn & Garden Plant Calcium provides calcium, retains nutrients deliverable in fertilizers, and promotes healthy microbial communities in the soil, translating to healthier plants and increased yields.

Calcium is one of the most important nutrients for plants, especially fruiting plants. Our Plant Calcium is the most bioavailable calcium on the market, providing the critical nutrient all plants need to thrive.

At a glance, here’s how your lawn and garden benefits from Plant Calcium:

  • RENEWABLE & SUSTAINABLE

    Calcean’s Plant Calcium is derived from oolitic aragonite sand, a renewable form of calcium carbonate that naturally regenerates in the ocean

  • BIOAVAILABLE CALCIUM

    High elemental calcium combined with high surface area and microporosity means aragonite is the most bioavailable calcium on the market

  • COST-EFFECTIVE

    Plant Calcium is effective in smaller quantities compared to standard limes, and can reduce fertilizer usage over time

  • EFFICIENT pH BUFFER

    Plant Calcium quickly and effectively buffers and maintains soil pH, correcting acidic soil

  • INCREASES TOLERANCE

    Plant Calcium increases tolerance to harsh conditions such as drought and close mowing

  • IMPROVES SOIL & FERTILIZER EFFICIENCY

    Plant Calcium immediately starts working in the soil, reviving and supplying nutrients, and it works with fertilizer to keep nutrients in the soil where they belong

  • EASY STORAGE & MAINTENANCE

    Calcean Plant Calcium requires no covering for outdoor storage. It spreads easily both wet and dry, with little to no dust, and is free-flowing (does not clog equipment)


Calcean recommends a soil test be conducted to ensure the correct amount of Lawn & Garden Plant Calcium is used. However, as a general guide for lawn and garden application, please see the dosage chart at right depending on your area’s size. Spread the recommended dosage of Plant Calcium over your lawn or garden using a standard spreader or mix into the soil.

As another helpful guide, check out our blog post for more on how to care for your potted plants! There, you’ll find a potting soil chart guide to reference when adding Plant Calcium to your container plants. Feel free to add a little more or less at your discretion!

For farmers and gardeners who use hydroponics systems and/or large-scale irrigation systems, Calcean also mills its Plant Calcium into a fine powder that can be mixed with water for applying calcium to plants through watering methods. The powder can also be mixed into soil, like its granular counterpart. For more information on OceanCal, please contact us.
