Why is the New Growth on a Rose Plant Drying Out?
New growth on a rose plant can dry out for several reasons:
Underwatering: Newly developing shoots and leaves require adequate moisture to sustain their growth. Ensure the rose plant is receiving regular irrigation, especially during periods of drought or hot weather.
Pest damage: Aphids, spider mites, and other pests can infest new growth, causing it to wither and dry out. Inspect the plant regularly for signs of infestation and apply appropriate insecticidal treatments as needed.
Disease: Fungal diseases such as powdery mildew and black spot can affect new growth, causing it to become discolored and dry. Treat the plant with fungicide to prevent further spread of the disease.
Nutrient deficiency: Roses require a balanced supply of nutrients for healthy growth. If the plant is deficient in essential elements like nitrogen or potassium, it can impact the development of new growth, leading to drying out. Fertilize the rose plant regularly with a balanced rose fertilizer.
Environmental stress: Extreme heat, cold, or wind can stress the rose plant, causing new growth to become damaged and dry out. Provide the plant with adequate shade or protection from harsh weather conditions.
