I use a garden sprayer and spray the plants once a week until harvest. We had great success with this product last year and things are looking good for this year as well. **Q: Can this be used on other plants like peppers or zucchini or is it just for tomatoes?** A: Yes it can be used on any type of vegetable that would benefit from extra calcium. **Q: is this organic?** A: it is pure organic calcium when your soil is low in calcium that is what causes end rot in your veggies. I have an degree in horticulture and own my own farm market . Been gardening over 30 years. you must applying weekly as once the plants get a taste of calcium that they were lacking naturally in the soil they devour the calcium you spray on to get healthy again.Granted the instructions on the bottle are not the best. weekly is the best plan. trust you will not be disappointed. **Q: I have only 4 tomato plants. How much liquid of product do I mix with water for a one quart bottle sprayer?** A: 1 tablespoon of the concentrated liquid per each quart of water. Spray liberally on all parts of plant surfaces. Provides needed calcium which is a common deficiency in all growing plants. Bonide 166 is concentrated Calcium Chloride solution. If you want extra nutrition, add .5 teaspoons of dry magnesium chloride crystals commonly known as Epsom salts. dsthornton_2005@yahoo.com ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Product! *by H***N on 30 June 2025* ### ⭐⭐⭐⭐⭐ This stuff works! *by R***W on 14 August 2025* ### ⭐⭐⭐⭐ Great *by R***I on 11 January 2025* ## Frequently Bought Together - Bonide Rot-Stop Tomato Blossom End Rot, 16 oz Concentrated Liquid Garden Fertilizer for Calcium Deficiency Indoors & Outdoors - Chapin 20000 Made in USA 1 -Gallon Lawn and Garden Pump Pressured Sprayer, for Spraying Plants, Garden Watering, Weeds and Pests, Polypropylene, Translucent White - Bonide Captain Jack Copper Fungicide 16 oz Concentrated Plant Disease Control Solution for Organic Gardening --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/254583308-166-rot-stop-tomato-blossom-end-rot-concentrate-fertilizer](https://www.desertcart.gr/products/254583308-166-rot-stop-tomato-blossom-end-rot-concentrate-fertilizer) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-04-23*
