How to Care for Creeping Zinnia

Creeping zinnia (Sanvitalia procumbens) is a low, mounding-to-trailing annual covered in cheerful little golden-yellow daisies with dark centers. Despite the name it isn't a true zinnia, but it shares the same love of heat and sun. It's a superb, easygoing choice for edging, containers and hanging baskets.

Light

Full sun is essential. Creeping zinnia flowers most heavily with at least 6-8 hours of direct light and can bloom nonstop all season in a hot, bright spot. In shade it grows sparse and flowers poorly.

Water

Low to moderate water; it is notably drought-tolerant once established. Let the top of the soil dry between waterings and avoid keeping it soggy, which invites rot. Container plants dry faster and need more regular water than those in the ground, but the plant generally prefers to run on the dry side.

Soil & Potting

Grows in average, well-drained soil and even tolerates poor, sandy ground. Sharp drainage matters far more than fertility. For containers and baskets use a light, free-draining potting mix; its trailing habit spills attractively over edges.

Humidity & Temperature

A warm-season annual that thrives in heat and tolerates dry air. Wait until after the last frost and warm soil to plant, as it is frost-tender. High heat and sun bring out its best, most continuous flowering.

Feeding

A light feeder. Too much fertilizer, especially nitrogen, produces leggy growth and fewer flowers. Poor-to-average soil suits it; if desired, use a dilute balanced or bloom fertilizer occasionally for container plants, but restraint gives the best flowering.

Propagation

Propagated from seed. Sow after the last frost where it is to grow, or start indoors a few weeks early. Seed needs light to germinate, so press it onto the surface and do not bury it. It germinates readily in warmth and often self-sows modestly in the garden.

Repotting / Pruning

As an annual it needs no repotting. It is self-cleaning and generally doesn't require deadheading, though a light shearing mid-season revitalizes plants that grow tired or stretched and encourages a fresh flush of bloom. Pinching young plants encourages a fuller, bushier mound.

Common Problems & Pests

Remarkably trouble-free and pest-resistant. The main risks come from overwatering and poor drainage, which cause root and stem rot, and from crowding in humid, stagnant conditions, which can invite powdery mildew or fungal spotting. Give it sun, airflow and lean, dry-ish soil and problems are rare.

Seasonal Care Tips

Sow or plant out after frost into warm soil. Water to establish, then keep it on the dry side through summer for maximum bloom. Shear lightly if it flags in midsummer heat. It flowers continuously until frost ends the season.
