3 cups water
dilute to make 2 gallon solution for 2~4 Rose plants.
coffee grounds. They can be reused as homemade fertilizer to give roses the acidic conditions they need to thrive. They also provide small amounts of potassium, nitrogen and magnesium. Simply sprinkle a handful of dry coffee grounds on the surface of the soil around rose bushes. Banana peels also contain potassium and are a rich source of the mineral. To use them as rose fertilizer, gardeners can bury the banana peels 4 to 6 inches deep at the base of the plants. Egg shells are another kitchen leftover ideal for re-purposing in the garden. They contain large amounts of calcium carbonate, an ingredient found in agricultural lime. They make an excellent addition to compost, and when crumbled into tiny pieces, they can be applied directly to the soil around roses. Pulverizing egg shells in a blender turns them into a fine powder for easy application. White vinegar adds acid to the soil, but it does not provide many nutrients, so is best used as a supplemental fertilizer. To make an acid-boosting solution for roses, combine 1 tablespoon of white vinegar with 1 gallon of water. The vinegar solution should replace one regular watering every three months. Epsom salts consist of sulfate and magnesium, nutrients that roses need to carry out many essential functions. For example, magnesium assists in photosynthesis and sulfate aids nutrient uptake. A mixture of 1 gallon of water and 1 tablespoon of Epsom salts should replace a regular watering once per month." — https://homeguides.sfgate.com/homemade-fertilizers-roses-31073.html
