Plant Care Guide:

Light: Sweet William ‘Midget’ thrives in full sun, needing at least 4–6 hours of direct sunlight each day to encourage abundant blooming. The more sunlight it receives, the more prolific the flowers will be. However, it can tolerate partial shade, especially in hotter climates.

Watering: Water regularly to keep the soil moist but not soggy. Sweet William prefers well-drained soil, so ensure the plant is not sitting in water. Avoid overwatering, as this can lead to root rot. Allow the top layer of soil to dry out slightly between watering.

Soil: Well-draining, slightly alkaline soil is ideal for Dianthus barbatus ‘Midget’. The plant thrives in rich, loamy soil that is moderately fertile. If growing in containers, use a quality potting mix with good drainage to prevent waterlogging.

Humidity: Sweet William prefers moderate humidity but can tolerate drier conditions. If growing indoors or in an area with lower humidity, it’s important to ensure the plant gets adequate air circulation to prevent fungal diseases. Avoid placing it in overly humid or wet environments.

Temperature: This plant grows best in warm conditions with daytime temperatures around 20–25°C. It can tolerate higher temperatures but may require some afternoon shade during very hot periods to prevent wilting.

Fertilising: Use a balanced, slow-release fertiliser to promote healthy growth and vibrant flowering. Apply a fertiliser with equal proportions of nitrogen, phosphorus, and potassium (e.g., 10-10-10). Organic compost can also be applied to improve soil fertility.

Common Pests: Sweet William ‘Midget’ may be susceptible to pests such as aphids, spider mites, and mealybugs. Regularly inspect the plant for pests, particularly on the undersides of the leaves and flower stems. If pest problems arise, treat with an organic insecticidal soap or neem oil to keep infestations under control.
