Sundial Series portulaca seeds are known to perform in poor soils and gardens prone to heat and drought. Avoid overwatering because plants will not perform well in wet and poorly-drained soil, making plants susceptible to crown rot, mold, and mildew. No serious pests or diseases but monitor regularly for aphids.
