Rhododendron 'Gibraltar' · also called Gibraltar exbury azalea · flowering

Deciduous Azalea 'Gibraltar' is an Exbury hybrid grown for large, frilled, vivid flame-orange trusses with a warm yellow flare in late spring, often lightly fragrant, followed by good autumn leaf colour. It thrives in acidic woodland borders. Being a Rhododendron, all parts contain grayanotoxins and it is ASPCA toxic to pets.

Ideal humidity: 40-60%

Watch for — Powdery mildew: White coating and premature leaf drop in late summer, worse in dry-rooted plants. Keep roots moist and mulched, improve airflow, and remove badly affected leaves.

The watering schedule, season by season

Deciduous Azalea 'Gibraltar' flowers best on steady, even moisture — let it dry out hard and it drops buds; keep it soggy and the roots rot before it can bloom. The base rhythm for deciduous azalea 'gibraltar' is keep evenly moist; water deeply 1-2 times weekly through summer, more in heat, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.

Spring & summer (active growth): Spring and summer (active growth and bloom): keep evenly moist, watering when the top 2-3 cm is dry — typically when the soil tells you it is time.
Autumn (slowing down): Autumn: ease back as flowering finishes and growth slows; let it dry a little more between waterings.
Winter (rest / dormancy): Winter / rest: water sparingly while it rests, then resume as new growth and buds appear.

Shallow-rooted and drought-sensitive; summer dryness checks bud set and stresses the plant. Water through dry spells and mulch heavily to keep roots cool and moist. Use rainwater where tap water is hard.

Seasonal and environmental adjusters
