Rhododendron fertilizer: Answer: fertilizer

Dear Angela,
in general, for rhododendrons, fertilizers are used for acidophilic plants; It is preferable to use a slow release granular fertilizer, to be spread on the ground around the plant, which will melt with rain and watering. An administration of granular fertilizer is sufficient for 4 months. If the foliage does not maintain a beautiful dark color over time, a couple of treatments with a soothing fertilizer should be used.
