Pot marigold (Calendula officinalis)

Calendula officinalis prefers a moderate watering schedule where the soil remains consistently moist but not waterlogged. Each time you water, aim to give about 200 ml ensuring that the water reaches the roots but doesn't pool on the surface. This allows the plant to absorb water effectively, supporting its vibrant bloom. More About Watering Techniques→

Calendula officinalis flourishes under full sun conditions, achieving its best health and flowering capabilities. Proper lighting encourages robust growth and vibrant blooms, enhancing its overall resistance to environmental stresses. More About Sunlight Requirements Techniques→

Calendula officinalis thrives best in temperatures ranging from 60°F to 70°F. This range ensures adequate warmth for proper growth without causing heat stress. Within this range, Calendula can efficiently perform photosynthesis and metabolic functions, leading to strong flower development and vibrant color expression.

Calendula officinalis thrives in well-drained soil, which prevents waterlogging and root rot. Ensuring proper drainage allows the plant to absorb nutrients efficiently and helps promote healthy growth. This plant prefers nutrient-rich soils that support robust growth. Amending the soil with organic matter like compost enhances the availability of essential nutrients, leading to vibrant blooms. It is essential for the soil pH to be slightly alkaline to neutral for optimal nutrient uptake. This pH range supports enzyme activity and increases the availability of critical nutrients for the plant. More About Soil→

For Calendula officinalis, it is best to apply liquid fertilizer at half the strength recommended on the package. When using slow-release fertilizer, apply it sparingly around the base of the plant, ensuring it does not contact the stem. A teaspoon per plant every three to four months is generally sufficient.

Although Calendula officinalis benefits from regular pruning, avoid cutting the plant too aggressively. Over-pruning can stress the plant and hinder blooming. Instead, focus on removing dead or faded flowers and lightly trimming back lengthy stems. This approach prevents unnecessary stress while allowing the plant to channel its energy efficiently into producing more blooms. Be cautious when pruning during excessively hot weather. Intense heat can stress the plant, and pruning might increase the stress. Consider early morning or late afternoon pruning to minimize the plant's exposure to direct sunlight during peak heat. Additionally, ensure the plant is well-watered after pruning to aid in its recovery and resilience. More About Pruning Techniques→
