Zonal Geranium (Pelargonium zonale)
The plant does not present an active pathogenic disease, but rather a state of poor maintenance known as accumulation of senescent debris. It is visually identified by the presence of brown flowers and dry leaves that remain attached. If not removed, these organic residues can favor the appearance of fungi such as Botrytis, especially in conditions of high humidity or watering over the flowers, which would eventually damage healthy tissues.
Cut the stems of flowers that have already dried to stimulate new growth.
Remove yellowish or dry leaves from the base to improve ventilation.
Remove fallen petals and leaves from the substrate to prevent fungal growth.
Check the underside of leaves for the geranium plume moth (borer).
2-3 times/week in summer; let substrate dry between waterings.
Full sun or very bright partial shade; minimum 6 hours daily.
Ideal 15-25°C; protect from intense frost.
Universal mix with good drainage; avoid prolonged waterlogging.
Flowering plant fertilizer every 15 days (spring-summer).
