Attributes of Scarlet gilia

Growth Rate

During its active growth season in the summer, scarlet gilia experiences a rapid growth phase, often marked by a quick increase in height, accelerated foliar production, and vibrant flowering. This rapid growth contributes to its impressive vertical reach and abundant nectar production which attracts pollinators. However, outside summer, growth speed considerably slows down.

Ideal Temperature

Water: Scarlet gilia thrives in temperate climates with moderate rainfall and prefers consistent moisture without being waterlogged. Weekly watering is ideal during its active growing season to promote optimal bloom and health, as it is typically grown outdoors due to size and ornamental flowers.

Fertilize: Scarlet gilia thrives with high phosphorus fertilization for enhanced blooms. Use a slow-release formula (5-10-5) in early spring, then a half-strength dose mid-summer. Limit to 1/4 cup per plant and stop fertilizing in late summer. Water post-application to ensure nutrient absorption.

Pruning: Scarlet gilia thrives with periodic pruning to maintain shape and encourage blooms. Prune from early to late spring, removing dead stems and spent flowers to foster new growth. Avoid heavy pruning to prevent stunted growth, while enhancing air circulation and reducing disease risk.

Propagation: Scarlet gilia is a vibrant perennial with striking red flowers. Propagation involves sowing seeds on well-draining soil without covering them. Consistent moisture is crucial, but avoid oversaturation. Using a slow-release fertilizer enhances growth, and acclimatization to outdoor conditions ensures survival post-germination.
