How to fix drooping roses
Roses are the favorite flowers of most boys and girls. Their bright colors and rich floral fragrance are extremely intoxicating. Planting a rose in a pot at home can not only add beauty and color to the interior, but also increase the interest of life. In the process of raising roses, yellowing of leaves often occurs, which greatly affects its ornamental value. Today I will analyze the reasons and solutions for yellowing of rose leaves:
Too much water causes yellowing
If there is no obvious change in the old leaves of the rose, but the new leaves are small and yellow-green, and the new shoots are shrinking and not long, it is most likely that the plant is waterlogged and has root rot due to excessive watering.
If the yellow leaves of the rose are mild, you can control the watering and wait until the pot soil is completely dry before watering again. If the yellow leaves are severe, you need to check whether the plant’s root system is rotten, trim the rotten parts and replant them in a new pot.
Insufficient light causes yellowing
Placing roses in a dark room for a long time is extremely detrimental to their growth. It will inhibit the formation of chlorophyll on the plant, causing the entire leaves to turn yellow and fall off.
Try to place the rose in a sunny place for maintenance. If it is always hidden indoors, you need to move it to the sun for a few hours every few days. Avoid direct sunlight at noon in summer.
Nutrient deficiency causes yellowing
If the rose is planted for too long, the root system of the rose will gradually absorb all the nutrients in the soil. If fertilizer is not applied in time to meet the normal growth of the plant, the color of the old leaves will become lighter, the new leaves will turn yellow, and even the flower buds will wither. .
Improper fertilization causes yellowing
Applying too much fertilizer to roses at one time or applying too concentrated fertilizer can easily burn the plant roots, causing the leaves to turn yellow and scorch, and in severe cases, the plant may die. Therefore, fertilization must be done sparingly.
If you want to prevent the leaves of roses from turning yellow, you need to pay attention to daily maintenance, watering and fertilizing properly, and getting plenty of sunshine.
Rose daily care tips
①Ambient temperature
Roses are light-loving plants. Sufficient light is beneficial to the growth and flowering of roses. It is recommended to keep them by a sunny window or in a yard. When the light is too strong, they should be properly shaded to avoid exposure to the scorching sun. If roses are placed indoors with insufficient light for a long time, poor ventilation will cause the leaves to turn yellow. If this happens, remove the yellow leaves in time and place them in a well-ventilated place. The optimal growth temperature for roses is 22-28°C.
②Water and fertilizer management
Since roses are fibrous plants with thin leaves that cannot store water, they must ensure sufficient water during the maintenance process. Strictly adhere to the principle of “don’t water without drying, water thoroughly”. It is recommended to use the method of soaking the pot to water thoroughly. Conducive to the matrix fully absorbing water. Roses bloom all year round, have dense branches and leaves, and require a lot of fertilizer. Too high or too low a fertilizer concentration will affect the growth of roses. It is recommended to directly purchase 3-4 months of slow-release fertilizer for fertilization, which can effectively avoid root burn due to insufficient fertility or excessive concentration. Condition.
③Control height topping
If you want roses to bloom continuously, have a plump plant shape, and have strong branches, you need to control the height and topping, and prune them in time. First, prune the withered flowers, three or four nodes downward from the flowers to promote buds. After pruning the remaining flowers, the height will be uneven. Cut the long branches appropriately to keep them at the same height. The height of the plant can be based on your own needs. If you want the plant to be tall when planting in the garden, top it from the middle or three-quarters of the bottom of the plant. If it is a potted plant, the plant should not be too high. Top it with one-half height from the bottom. After topping, the water absorption of the plant will be reduced, and the watering frequency can be reduced according to the actual situation to avoid root rot due to excessive water.
④Pest and disease control
Roses are commonly known as “medicine jars”. They focus on prevention and treat the disease with the right medicine. Once a single pot becomes infected, it is recommended to isolate and treat it to prevent the spread. The main pests include red spiders, aphids, thrips, etc. For minor pests, physical control can be used first, such as removing the damaged parts, flushing away the pests with high-pressure water, wiping the leaves with alcohol, hanging yellow boards, etc. If this is not possible, then consider purchasing corresponding chemicals for spraying. Give. Common diseases include downy mildew, powdery mildew, black spot, etc. You can buy medicines for common diseases every half month for preventive spraying. Regularly clean the dead rose leaves and weeds in the pot. You can clean the bottom leaves to keep the environment ventilated. ; If a certain disease appears serious, purchase the corresponding agent separately and spray it.
