About this plant
Mrs. G.G. Gerbing is an evergreen azalea prized for its pristine white spring blooms and reliable performance in the Southeast and Gulf Coast regions.

Questions before you buy
Which size should I choose?
The 1-gallon container is a younger plant ideal for budget-conscious buyers or those comfortable waiting a season for fuller structure. The 3-gallon offers an established specimen that makes an immediate visual impact and reaches maturity faster.
When should I plant my azalea after it arrives?
Plant as soon as possible after arrival to minimize transplant stress. Spring and fall are ideal planting seasons; if arrival coincides with summer heat, water deeply and provide afternoon shade until the plant is fully established.
How large does Mrs. G.G. Gerbing get?
Expect mature dimensions of 6-8 ft tall and 5-7 ft wide; in ideal Southeast conditions over many years, it can reach 8-10 ft. Growth is moderate, roughly 8-12 inches per year, so full size takes 8-10+ years to achieve.
How much sun does this azalea need?
Mrs. G.G. Gerbing performs best in partial shade to filtered sun, with morning sun and afternoon shade being ideal. In cooler, humid climates, it tolerates more direct sun; in hot regions, afternoon shade is essential to prevent leaf scorch.
What are the hardiness zones for this plant?
This variety is rated for USDA zones 7-10, with most reliable performance in zones 7b-9. It performs best in the Southeast and Gulf Coast; gardeners in zone 7a should choose a sheltered, protected location with good drainage and wind protection.
What should I do during the first year after planting?
Water consistently to keep soil evenly moist but not waterlogged. Apply 2-3 inches of mulch around the base, avoid fertilizing the first year, and allow the plant to focus energy on root establishment. Prune only to remove any damaged branches.
