This is when the plant begins to grow intensively and needs many vitamins and minerals, which it can obtain directly from the soil. To fertilize rhododendrons, you can use commercially available liquid nutrients. Those dedicated to rhododendrons will work best. They are rich not only in phosphorus and potassium, but also contain nitrogen. This ingredient increases and stimulates flowering. However, nitrogen fertilizers should not be used in autumn. Nitrogen can extend the growing season, which means that the plant will not have time to prepare for the coming winter.

One of the simplest home ways to fertilize rhododendrons is using coffee grounds. For them to be effective, you do not need to prepare liquid mixtures. Just take a shovel and mix the coffee grounds into the soil around the bushes. In this way, you will not only provide vitamins and minerals for the plant to absorb, but also loosen the soil and prevent moisture loss. Acid grounds slightly acidify the soil, which rhododendrons love. Additionally, they contain nitrogen, phosphorus and potassium, i.e. all the ingredients needed for the proper growth and flowering of rhododendrons.

Water the rhododendrons with the conditioner prepared in this way once every three weeks.
Apple peels, like banana peels, are rich in vitamins and minerals valuable to plants. They contain potassium, phosphorus and nitrogen, which are necessary for the proper growth and flowering of plants. Fertilizers based on apple peels will quickly nourish the bushes and make them more resistant to diseases and pests. Rhododendrons fertilized in this way will bloom like never before.
