Geranium Tips and Care for Thick, Full Plants 🍃🌸// How's It Growing?

About Geranium

Geraniums burst with vivid red, pink, and white flowers from spring to fall. Their bushy growth and zoned leaves make them patio stars and indoor favorites.

Native to South Africa, they thrive in warm, dry spots with well-drained soil. That's why they handle drought like champs.

Indoors, give them sun and smart watering for years of blooms. Outdoors, plant after frost for summer color.
