My mom gave me a hanging rose pot but it started to die or maybe is dead. I would like to do or try something to bring it back to life.

    I think the coffee grounds are used to add acidity to the soil, which roses love. Eggshells are usually used to keep away slugs and snails by irritating and cutting their bodies when they crawl over them. Good luck!

    Hi, I'm pretty sure that the egg shells have calcium in them which is very good for plants. I don't know why some call for the use of coffe grounds but have been told by many to mix in the "dryed" grounds with my plants to help with the soil. Sorry, wish i knew more. You could Google broken egg shells for roses or same with coffee grounds and see what you get. Or Pintrust and Hometalk.com are great places to get info. Hope this helps.

    Crushed egg shells add much-needed calcium to the soil as they break down – which can help prevent blossom rot in tomatoes. Blossom rot is better known to most as “those dreaded black spots” that form on the end of tomatoes, peppers and squash that can all but ruin a crop. It just so happens that blossom rot is caused by a lack of calcium in the soil – which crushed egg shells can help to add back.

    Coffee grounds are a great addition to planting holes and around plants as well

    Along with those egg shells we add in a few tablespoons of coffee grounds to the planting hole as well. Coffee grounds release nitrogen, potassium, phosphorus and other minerals as they break down – acting as a great natural slow-release fertilizer to the plants.
