Points to consider when planting tree roses in different climates
Tree roses grow very differently under different temperatures, so there are many different points to consider when planting them in the north and south.
One, the suitable growing temperature for roses
Roses thrive well in daytime temperatures of 15-26°C and nighttime temperatures of 10-15°C.
Two, the cold resistance of roses
Tree roses can generally withstand temperatures as low as -15°C, and this is still just a preservation value. Cold resistance is not only related to temperature but also depends on three factors:
1. External environment: whether the climate is dry and cold or wet and cold, whether the wind is strong or weak;
2. Seedling growth: the size of the seedlings, generally larger seedlings are more cold-resistant;
3. Variety of roses: some varieties with strong cold resistance can withstand lower temperatures.
Based on the planting feedback from rose enthusiasts in various regions in recent years, it can be clearly stated: in areas south of Beijing, there is no need to consider the cold resistance of roses, as they can safely survive the winter without any anti-cold measures; in areas north of Beijing, where the temperature commonly drops below -20°C in winter, it is recommended to take anti-cold and windproof measures for all rose seedlings to prevent frostbite and desiccation.
Three, the heat resistance of rosesDifferent rose varieties have different degrees of tolerance to high temperatures. When the temperature is >35°C, some varieties may show slow growth, reduced flowering, and smaller flowers, while other varieties still perform well with vigorous growth and flowering.
Therefore, for rose enthusiasts in areas where the temperature is commonly above 30°C in summer, they can pinch off the rose buds in summer to accumulate nutrients for blooming in autumn, or they can choose heat-resistant rose varieties to plant.
Four, the dormancy period of roses
When the temperature continues to be below 5°C for a period of time, roses will gradually stop growing and enter a dormant state.
In winter dormancy, roses stop nutrient transport, and the nutrients in the branches are collected and stored in the roots. When the temperature warms up in spring, new buds and branches sprout, and the roots redistribute the stored nutrients for (G-Y) plant growth. In this way, the nutrition and energy accumulated over the winter have a very strong爆发力 in the spring.
In areas where the temperature is commonly above 5°C in winter, roses cannot enter dormancy, and many varieties that bloom only once a season or have poor blooming performance may show little or no blooming.
The above is [] a method introduction about the points to consider when planting tree roses in different climates, which can be used as a reference suggestion.
