Volcano phlox will tolerate a range of soils but will perform best in a well-worked fertile soil.
Will tolerate moderately dry conditions. Performs best when well-watered. Watering at the base with a soaker hose is encouraged. Overhead watering, or watering at night can promote conditions conducive to mildew.
In Spring, use a slow release balanced plant food suitable for flowering plants.
Very tolerant but not entirely impervious to mildew.
Phlox can be affected by spider mites and thrips.
Volcano phlox are very mildew tolerant, but it's good gardening practice in general to take steps to avoid conditions that can promote mildew. Follow spacing recommendations when planting. Crowded plantings can reduce air circulation and promote mildew. Water phlox at the base of the plant and not from above. Soaker hoses are great. Never water your garden at night, as this promotes mildew and other diseases in all plants in your garden. Morning is the best time to water the garden.
