Yes—mandevillas can enter true dormancy, but only under specific, controlled environmental conditions: consistent temperatures between 45–55°F (7–13°C), near-total cessation of growth, and a sharp reduction in water and light. Unlike deciduous trees, mandevillas do not require dormancy to survive—but inducing…
Most plants showing leaf drop, stem browning, or apparent stillness in late fall through early spring are dormant—not dead. True death is confirmed only when all living tissue—including cambium under the bark, root tips, and crown—has turned uniformly brown, mushy,…
Applying dormant oil to fruit trees is a proven, low-risk, highly effective method of pest suppression—but only when done correctly. Dormant oil works by physically suffocating overwintering insect eggs, soft-bodied adults (like scale crawlers and spider mites), and fungal spores—not…
Yes— tropical hibiscus (Hibiscus rosa-sinensis) typically enter a state of dormancy—or at least pronounced metabolic slowdown—when exposed to sustained cool temperatures below 50°F (10°C), shorter daylight hours, and reduced light intensity. This is not true dormancy like that seen in…
