Volcano® Ruby Garden Phlox will benefit from using a slow-release granular formula when initially planted. When the first flowers fade, apply a balanced, diluted, liquid fertilizer to encourage a second flush of blooms. Incorporating generous amounts of organic matter into the soil, particularly if the soil is lean or sandy, delivers essential nutrients slowly to the roots. Try using peat moss, garden compost, or well-rotted manure.
Water Volcano® Ruby Garden Phlox regularly, ideally in the morning, maintaining moist but not soggy soil. Avoid overhead watering by using drip irrigation or hand watering at the base of the plant to avoid splashing water on the leaves. Deadhead terminal blooms to encourage longer flowering. New flower buds will appear along the stem for a second flush, and they will continue to flower, often up until fall. Divide Volcano Ruby Garden Phlox plants after 3 years.
