What Is A Homemade Fertilizer For Hydrangeas

Natural fertilizers such as compost, manure, and nitrogen-fixing bacteria can help feed hydrangeas for glorious blooms. Compost is simply decomposed organic matter. Manure is better for providing vital nitrogen to the soil. Nitrogen-fixing bacteria can help keep your soil healthy and provide a steady release of nitrogen to the plants.

Choose an organic fertilizer with a slow-release formula that has been specially formulated for acid-loving plants like hydrangeas. Avoid fertilizers that are high in quick-release nitrogen, as they can burn young or tender roots. 

Fertilize at least once in spring and again after buds are set or during the peak flowering season. To avoid overfeeding, use a maximum application rate of 5 lbs/1000 sq ft every 3 months. Applying granular fertilizer pellets directly on top of foliage often damages leaves and stalks, so keep them away from the stem area at all times.

Mix one part fertilizer to four parts water before applying it to established hydrangea plants — small amounts used often are more effective than heavy applications less frequently. A diluted liquid solution around the drip line is ideal, but avoid oversaturating the soil near the base of the bush as this may lead to root rot issues. For best results, follow with watering afterward for optimum absorption into the root system.
