Drench the soil surface until excess water begins to flow out of the bottom of the pot.Light pruning, deep watering, and a layer of mulch in fall help hibiscus conserve energy and stay protected through winter. Bring tropical varieties indoors before it hits 40°F, and cut back on watering to prevent root rot. Fall prep boosts blooms by keeping roots strong and reducing pest issues.Hibiscus plants can benefit from the occasional use of coffee grounds as alternate fertilizers.

They perform best when they receive ample sunlight, but too much shade can cause the plants to become leggy, with fewer buds and reduced flowering.A Hibiscus might not bloom or bloom as much if the plant receives too much Nitrogen. Hibiscus generally does well with higher Nitrogen levels, but if the threshold is met, it can stop the plant from blooming.Hibiscus syriacus, or simply hibiscus, is a deciduous shrub known for blooming in the summer with large, colorful, 5-petaled flowers that can grow to be 3 or 4 inches across and which have a prominent stamen at the center.

Hardy Giant Hibiscus Species Information Lifespan – Can live up to 50 years or more when planted in optimal conditions. Type – Deciduous. Soil Requirements – Prefers well-drained, slightly acidic to acidic, moist, rich, and fertile soil with full sun exposure. Growth Rate: Perennial hibiscus generally reach their mature height within two or three years and return to that height each year. Best growth occurs when plants have ample moisture. Many hardy hibiscus can bloom the first year from seed started in early spring.Both hardy and tropical hibiscus plants need special care in fall to survive the winter, but how much depends on which hibiscus you are growing. In winter, hardy hibiscus can remain outdoors with a few precautions to keep harsh weather from damaging or killing it, while tropical hibiscus should be overwintered indoors.Hardy hibiscus is adapted to colder climates, thriving in USDA Zones 5–8.

This will help your plant survive those cold winter winds and will make it easier to apply mulch. Apply a thick layer of mulch. This is the most important step to successfully overwinter your hibiscus.
