Roses bloom beautifully, with full and beautiful flowers and a long flowering period. They bloom in spring, summer and autumn, but not in winter. So how cold-resistant are roses? Many flower-growing friends know that roses cannot be watered all the time. Keeping the soil moist is not good for the growth of roses. Why is this? When can we water them? Let's take a look at what's going on with these questions! How is the cold resistance of roses?Roses are not very cold-resistant, and in ancient times they were called "medicine jars". If pests and diseases are not prevented during the maintenance process, they will be easily infected by pests. Once the plants are infected with pests and diseases, they will not bloom and the plants will wither. Therefore, during the maintenance process, it is necessary to ensure indoor ventilation, disinfect regularly, and spray with 1000 times diluted benomyl. Why can't the soil of roses be kept moist for a long time?Usually we water the plants when the soil is dry and when it is wet. When the surface of the pot soil is dry for two or three centimeters, we should water the plants in time. We cannot water them as we please, depending on our mood. If we are in a good mood, we may even water them two or three times a day! You should know that water in the soil generally evaporates from top to bottom. In this repeated cycle of dryness and wetness, the roots of the plants, after experiencing a slight sense of crisis, will redouble their efforts to stretch and grow new roots in order to find and absorb more water. How to know if roses are lacking waterWhen watering, avoid watering halfway. To water the roses properly, you must understand the natural habits of the roses, and you must also balance the dryness and wetness of the pot soil according to seasonal changes, temperature conditions, and the size of the plant. Only in this way can the water content of the rose pot soil meet the water requirements necessary for its growth. Roses need a moist growth environment. They are neither drought-resistant nor flood-resistant. They need soil with a certain water retention and good drainage. If the roots of roses are soaked in water for a long time, the roots will rot due to lack of oxygen. Therefore, you should see that the surface of the pot soil is dry. You can only see the moist soil by pressing down 2 cm with your finger. Then water it. |
