Natural Fertilizers for Hydrangeas
One alternative method to fertilize hydrangeas is to use natural fertilizers that are easily available at home or in the garden. Compost, composed of organic kitchen waste, yard clippings, and other biodegradable material, can be a great source of nutrients for hydrangeas. Manure from farm animals like cows, horses, or chickens is another natural fertilizer that can enrich the soil and promote healthy growth in hydrangeas. Wood ash from fireplace or bonfires is rich in potassium and can be sprinkled around hydrangea plants to boost their blooming ability. Epsom salt, which is magnesium sulfate, can also be used as a natural fertilizer for hydrangeas to promote vibrant flower colors and overall plant health.
DIY Fertilizers for Hydrangeas
If you prefer to make your own fertilizers for hydrangeas, there are several DIY options that you can try. A banana peel fertilizer can be created by chopping up banana peels and burying them near the base of hydrangea plants. The peels will decompose and release potassium and other nutrients into the soil. Another DIY option is to make a coffee grounds fertilizer by mixing used coffee grounds with water and pouring the mixture around hydrangea plants. Coffee grounds are rich in nitrogen, which can promote green leafy growth in hydrangeas. You can also create a homemade eggshell fertilizer by crushing eggshells and sprinkling them around hydrangea plants. Eggshells are a good source of calcium, which can help prevent blossom end rot and promote strong root development.
