Place the "Mountain Fire" Pieris japonica plant in a location where it receives partial or full sunlight. Use soil that is slightly acidic and moist.
Water this plant frequently, at least once a week. Poke your finger in the soil, and make sure the first 3 inches of dirt are moist. Do not let the soil dry out, but avoid overwatering the plant.
Apply a thick layer of mulch that is 2 to 3 inches deep. Pine needles are a good mulch for this plant. Layer the mulch around the base of the plant. This helps the soil to remain moist.
Use a granulated even-ratio fertilizer, such as 10-10-10 fertilizer or cottonseed meal. You need 1 pound of fertilizer per 100 square feet of soil. Fertilize the plant in the winter and again in the spring after the plant flowers. After adding the fertilizer, water the plant well.
Remove any faded or dead flowers. Prune back damaged and diseased limbs.
Treat the plant once a week with neem oil or insecticidal soap in order to get rid of lace bugs.
