Suitable flowers for the Northeast
In the cold and long winter region of the Northeast, many flower enthusiasts are often troubled by the problem of plant overwintering. In fact, by choosing varieties with natural cold resistance genes and cooperating with scientific maintenance methods, a colorful sea of flowers can also bloom in a garden with temperatures as low as -30 degrees Celsius. The following five cold-resistant flowers, verified by practice, will completely change your understanding of growing flowers in the Northeast.
Winter Jasmine: The harbinger of spring on the frozen earth
Growth characteristics in extreme cold environments
As the first flower of early spring in the Northeast, winter jasmine can survive in an environment of -15 degrees Celsius, and its lignified stems can effectively resist frost damage. Special physiological mechanisms allow it to maintain vitality under snow cover and quickly sprout after thawing.
Landscape matching skills
It is recommended to plant with evergreen shrubs. The bright yellow flowers are more vibrant against the deep green background. During the full bloom period, the contrast with the remaining snow can create a unique visual effect.
Syringa: The fragrant cold-resistant model
Key points for overwintering maintenance
Use the deep planting method, with a soil depth 10cm more than usual. Keep the natural fallen leaves in winter to cover the roots, forming a natural insulating layer. Pay attention to maintaining slightly acidic soil (pH 5.5-6.5).
Suggestions for variety selection
In the Northeast, 'Siberian Syringa' and 'Red Syringa' are preferred, with a flower bud differentiation temperature threshold of -25 degrees Celsius, and ariel density 40% higher than that of common varieties.
Malus: All-around player for flower and fruit appreciation
Low-temperature adaptation mechanism
By accumulating a large amount of soluble sugars to reduce cell freezing point, the fruit hanging on branches over winter makes it an important landscape element in the winter garden. Pay attention to choosing suitable varieties for the north, such as 'Winter Red'.
Light management tips
Plant in an east-west direction to ensure 4 hours of scattered light per day. In summer, set up a sunshade net to prevent leaf scalding and premature defoliation.
Hosta: An amphibious star indoor and outdoor
Suitable flowers for the Northeast
Temperature transition plan
Plants need to be moved indoors before the end of October, maintaining a dormant temperature of 2-5 degrees Celsius. Use a gradual temperature adjustment method to prevent dormancy disorders caused by sudden temperature changes.
Disease prevention system
Establish a comprehensive control system focusing on biological control: regularly spray garlic extract to prevent gray mold, and hang yellow sticky boards to monitor the density of thrips populations.
Hemerocallis: Low-maintenance high-yield model
Soil improvement plan
Add 5kg of decomposed pine needles per square meter to improve clayey soil and use ridge cultivation to enhance drainage. Apply bone meal in spring and autumn to increase frost resistance.
Strategies for extending the flowering period
Use the method of dividing plants alternately, dividing the plants into early, middle, and late stages of maintenance, which can extend the overall flowering period from the usual 20 days to 45 days.
By scientifically selecting varieties and targeted maintenance, the Northeast region can completely create a garden with scenery all year round. It is recommended to establish a local flower enthusiast group to share microclimate data of various communities and try to introduce advanced cold-resistant varieties such as珍珠梅 (Pearl梅花) and 锦带花 (锦绣带花) to gradually enrich the diversity of garden plants.
