Nutri-Cal Liquid Calcium, Concentrate, 16 oz

Although Nutri Cal is actually a mild fertilizer, added calcium can help prevent blossom end rot, which is a common disorder in tomatoes, cucumbers, and squash.

This product provides the calcium your plants need in an easily absorbed form. Great for lawns, too. Apply as a foliar spray every 2 weeks. Non-toxic and safe when used as directed.
