hyacinth is cold-resistant -10~-15℃, has strong cold-resistant, can sprout and bloom in early spring, and the bulbs can grow into roots at 2℃, and will not be frostbite when tolerate low temperatures of -15℃ for a short time. However, in order to ensure that the plants can overwinter smoothly, the room temperature must be stabilized between 12 and 25℃ during daily maintenance.
Winter maintenance method of hyacinth
When soil cultivation and maintenance of hyacinths, the amount of watering needs to be strictly controlled after the temperature drops in winter. You can regularly observe the wet and dryness of the pot soil, and then water it appropriately after the pot soil is dry. Before watering, place the water in the sun to dry to increase the water temperature and avoid cold water irritating the root system.
When raising and protecting hyacinths, you should pay attention to changing the water frequently during winter maintenance. During this period, you can change the water every 5 to 7 days to avoid contamination of water quality. The water temperature must be consistent with the room temperature every time you change the water, otherwise it will cause frostbite of the leaves and withering and yellowing.
The germination and growth of hyacinths cannot be separated from the nourishment of light. When maintaining hyacinths in winter, sufficient light must be ensured. In winter, the light is weak, so it can be placed in an environment with good lighting. If it grows in a dark and dull environment for a long time, it will make it difficult for hyacinths to germinate and resume growth, and it is easy to grow poorly in the later stage.
