Down to Earth Liquid Calcium 5% | 1gal - OMRI Listed - Makes 128 Gallons - (Case of 4)

Foliar-Ready Liquid Calcium to Prevent Blossom End Rot, 1gal

Blossom end rot in tomatoes, peppers, and squash traces back to inadequate calcium availability in developing fruit tissue, often made worse by inconsistent watering or excess nitrogen that limits how calcium moves through the plant. Down To Earth Liquid Calcium 5% delivers calcium in a foliar-ready liquid form so growers can correct or prevent that deficiency directly at the leaf and fruit level rather than waiting on slower root uptake alone.

The 1gal size, sold as a case of four, makes up to 128 gallons diluted and suits market growers and larger operations applying Liquid Calcium regularly across a season of fruiting crops.

Frequently Asked Questions

What causes blossom end rot in tomatoes?

Blossom end rot is tied to inadequate calcium availability in developing fruit tissue, which can result from calcium deficiency itself, inconsistent watering that limits uptake, or excess nitrogen that restricts calcium movement within the plant. Foliar calcium applications address the availability side of that equation directly.

Is Down To Earth Liquid Calcium 5% OMRI Listed?

Yes, all three sizes of Liquid Calcium 5% carry OMRI Listing. The concentration and certification stay the same whether you buy the 32oz, 1gal, or 2.5gal size.

How is Liquid Calcium 5% applied as a foliar spray?

Foliar applications of calcium are a common way to correct or prevent deficiency symptoms. Dilute according to the current label and apply directly to leaf surfaces.

What plants benefit most from Liquid Calcium 5%?

Fruiting vegetables such as tomatoes, peppers, and squash benefit the most, since calcium deficiency in these crops commonly shows up as blossom end rot and other fruit-quality problems. Any plant showing new-growth yellowing or tip burn from calcium deficiency can also benefit.

Can Liquid Calcium 5% be applied through irrigation instead of as a foliar spray?

Yes, it can be applied as a soil drench or run through irrigation in addition to foliar spraying. Follow the current label for dilution rates specific to each application method.
