Reasons for Rosemary Leaf Curling and Remedial Treatment Methods
You may not be aware of the reasons for rosemary leaf curling and the methods for remedial treatment in terms of horticulture knowledge. Let's take a look together.
Reasons for Rosemary Leaf Curling and Remedial Treatment Methods
Rosemary leaf curling may be caused by improper watering, incorrect fertilizing, or pest infestations. Therefore, during the growing period, it is necessary to water moderately, maintain the soil slightly moist without waterlogging, and apply a dilute fertilizer solution once a month to meet the growth requirements. If over-fertilized, it is necessary to loosen the soil and water immediately to dilute the fertilizer, and apply pesticides for pest control.
What Causes Rosemary Leaf Curling?
Rosemary leaf curling may be caused by improper watering, incorrect fertilizing, or pest infestations. Excessive watering and fertilizing during maintenance can damage the rosemary roots, leading to leaf curling.
If rosemary leaves curl and fall, it may be due to pests and diseases. We should strengthen management during planting, take care of aspects such as lighting, temperature, and watering, focus on prevention, and apply pesticides in a timely manner for prevention.
Reasons for Rosemary Leaf Curling
During the growing period, if rosemary leaves curl, it may be due to an unsuitable environment. Rosemary prefers a warm and well-ventilated climate. If it is kept in a closed and dark environment for a long time during maintenance, the leaves will curl and turn yellow. If the environment is unsuitable, it should be placed in a suitable environment for care.
Rosemary leaf curling may also be due to excessive fertilizing or high fertilizer concentration during maintenance. If caused by improper fertilizing, it is necessary to loosen the soil for rosemary and ensure drainage.
Methods for Treating Rosemary Leaf Curling
If rosemary leaves curl and dry, they can survive with timely emergency measures. Rosemary has strong drought resistance, and watering immediately after the leaves dry can restore growth.
1. Sufficient lighting in the growing environment: Rosemary can be grown in a well-lit environment, but during the hot summer, it needs to be shaded. It can also grow in a semi-shaded environment, but it should not be placed in a poorly lit area, otherwise the branches and leaves will grow excessively and become thin.
2. Sufficient nutrients during the growing period: Rosemary also needs fertilizing. In addition to preparing fertile soil, a dilute fertilizer solution should be applied once a month during the growing period to meet the growth needs of rosemary, making the roots more developed. When rosemary forms flower buds, appropriate supplementation of 1-2 times of phosphorus fertilizer can promote flowering.
3. Pinching to inhibit excessive growth and promote branching: Rosemary grows quickly. When using it, first select the overgrown or leggy branches, and after cutting the top of the leaves, it will inhibit the excessive growth of rosemary and promote more branching, making the plant more full and the branches stronger. Pruning can also increase ventilation and light.
Rosemary Leaf Curling and Yellowing
Rosemary does not grow very fast, but if the ventilation in the growing environment is poor, the leaves may turn yellow. At this time, it should be placed in a well-ventilated area for care. Otherwise, the whole plant may become weedy due to poor ventilation.
Rosemary Leaf Curling with Pests
If there are few pests, they can be captured directly, or they can be repelled with water or soap water, which is simple and effective. Alternatively, you can purchase professional pesticides from a pharmacy and spray them on the plant.
