The leaves of the rose I just bought are yellow
Early summer is the golden time for planting roses, but many flower friends find that new rose seedlings often have yellow leaves. Faced with fading and curling leaves, improper maintenance may directly lead to plant wilting. This article will systematically sort out the coping strategies for yellow rose leaves to help novice flower farmers quickly master scientific maintenance methods. Management key points during the environmental adaptation period: Precise pruning and preservation of vitality. Newly purchased roses need to immediately cut off the yellow leaves and open flowers. The seemingly cruel operation actually follows the plant growth law of "removing, saprotic and rejuvenating". Keep 3-4 healthy green leaves. Excessive retention of damaged tissue will continue to consume the nutrients stored by the plant. The golden rule of water regulation Yellow leaves do not mean water shortage, and 80% of cases stem from excessive watering. After pouring thoroughly with root-fixing water for the first time, wait until the surface layer of the soil is 3 centimeters dry before replenishing water. Combined with leaf spray in the morning and evening, it is better to maintain air humidity of 50%-60%. Growth factor balance strategy Light intensity gradient transition Rose undergoing transportation takes 7-10 days to slow down seedling stage. It is recommended to place north-facing window sill to receive scattered light. After the new shoots germinate, gradually increase the duration of direct light to avoid sudden exposure to cause secondary stress reactions. The principle of suspension of nutrient supply is strictly prohibited until the root system is restored. Capillary root damage caused by transportation requires a 2-3 week repair period. A small amount of rooting powder can be added to promote recovery, and thin fertilizer can be applied frequently after the new leaves have been unfolded for 3 pieces. Micro-environment optimization techniques maintain a temperature difference of 8 ° C between day and night to facilitate recovery, with a ventilation period of at least 4 hours per day. It is recommended to use perlite mixed humus soil for basin soil to improve the permeability of the substrate. Rotate the flowerpot regularly to ensure uniform light reception and prevent yellow leaves on one side.
After three weeks of systematic maintenance, 90% of yellow-leafed roses can be restored to vitality. The key is to grasp the three cores of "slow adaptation, fine pruning, and water control" and combine the gradual adjustment of environmental factors to allow the newly started roses to smoothly pass the adaptation period and bloom healthy new shoots.
