Where to Plant Melampodium

Plant melampodium in a location that receives full sun and has well-drained soil with a slightly acidic or neutral pH. This plant is not picky about its growing conditions as long as these basic requirements are met. Melampodium grows well in containers, garden beds, and mass plantings.

How and When to Plant Melampodium

Wait until all danger of frost has passed before planting melampodium. When transplanting a nursery plant, ensure the hole is at least the same size and depth as the pot. Water the plant well before removing it from its container, then place it in the ground and backfill with the original soil. Space multiple melampodium plants about 12 inches apart.

Melampodium Care Tips

Melampodium is a low-maintenance plant when grown in its preferred light and soil conditions.

Light

Melampodium thrives in full sun, which promotes abundant blooming and a compact growth habit. Insufficient sunlight can cause the plant to become leggy.

Soil and Water

Native to regions with rocky soil, melampodium requires well-drained soil to thrive. It prefers slightly acidic soil with a pH between 5.5 and 6.5 but can tolerate slightly higher pH levels. Regular watering is beneficial, but allow the soil to slightly dry out between waterings as the plant is drought-resistant.

Temperature and Humidity

Melampodium is heat-tolerant but not cold-tolerant. High humidity can lead to powdery mildew, so ensure adequate air circulation around the plant.

Fertilizer

To encourage continuous blooming, use a slow-release or general-purpose liquid fertilizer following label instructions.

Pruning

Melampodium typically outgrows its spent blooms quickly, so deadheading is not usually necessary. Planting in full sun and pinching back stems early can help prevent legginess.

Pests and Problems

Melampodium is generally resistant to pests and diseases, but powdery mildew can be a concern in hot, humid climates. Adequate spacing and air circulation can help prevent this issue. Slugs and snails may feed on the plant but can be removed by hand. Melampodium is deer-resistant.

How to Propagate Melampodium

Melampodium is propagated from seed. Directly sow seeds outdoors after the last frost in spring, barely covering them with soil as they require light to germinate. Keep the soil moist, and thin seedlings once they appear. Starting seeds indoors about six weeks before the last expected frost date can give you a head start on the growing season.
