Calcium is critical to the health of your plant, contributing to the strength of cell membranes and regulation of nutrient use. Calcium is known to play a major role in the quality of many crops, including peppers, tomatoes, and watermelon. It is also able to reduce the effects of heat stress in plants. CalCarb foliar booster works great in both indoor and outdoor environments where the atmosphere cannot be contained. As always Xtreme Gardening products are free of GMOs (genetically-modified organisms) and harmful pesticides.

Foliar Booster is for indoor & outdoor use’”no tanks or burners required!

Established Plants – Foliar Spray – Add 1 tsp per quart (liter) of water [1 tbs per gal] into sprayer. Mix well. Spray foliage focusing on underside of plant leaves. Repeat every 5-7 days for best results.

NOTE: CalCarb leaves a beneficial white residue of natural calcium. It may be rinsed off after 36 hrs, but left on will achieve best results. CalCarb is best applied alone; wait 36 hrs before applying other foliar nutrients. Clean sprayer after every use.

Fruiting & Flowering Plants – Foliar Spray – Add 2 tsp per quart (liter) of water. Mix well and add to sprayer. Spray focused “pop-shots” on the underside of outermost leaves. CalCarb need only be applied to 4-5 leaves. No need to saturate entirety of foliage. Avoid fruits and flowering bodies.
