Main factors affecting the blooming of geraniums

Today's sharing: The cultivation content of the herbaceous flower geranium, the main factors affecting the blooming of geraniums, are introduced as follows:

Geranium, also known as the common name "pelargonium," is native to South Africa and is a perennial herbaceous plant. The leaves are palmate with long petioles, the edges are mostly serrated, and the leaf surface has deep annular patterns. The corolla usually has five petals, the inflorescence is umbrella-shaped, and grows at the top of the erect flower peduncle. Because the flowers are dense and round like a ball, it is also known as the "common name 'pelargonium'." Flower colors range from red, white, pink to purple. The blooming period starts from early winter and continues until early the following summer. Potted plants are suitable for indoor and outdoor decoration; they can also be used as flowers for spring flower beds.

The main factors affecting the blooming of geraniums are as follows:

(1) Overwatering or exposure to rain, causing long-term waterlogging in the pot, leading to root rot, yellowing of leaf edges, or excessive growth of the plant, all affect blooming.

(2) Over-fertilization, especially excessive nitrogen fertilization, can easily cause excessive growth of branches and leaves, resulting in no flowering or sparse flowering, and poor flower quality. However, insufficient or no fertilization will also affect the normal growth and flowering of the plant. Therefore, more phosphorus and potassium fertilizers should be applied appropriately in early spring or early autumn.

(3) Excessive or low temperatures, with indoor room temperatures above 20°C in winter and poor ventilation, can cause excessive growth of branches and leaves, affecting blooming the following year. However, if the temperature drops below 0°C during the winter, it can easily suffer frost damage, causing the leaf edges to turn yellow and become soft. Geraniums are also sensitive to temperature changes; sudden changes can cause flower drop.

(4) Too much sunlight, with direct exposure to the sun in summer, can easily cause leaf edges to suffer sunburn, resulting in poor growth or the dropping of flowers and leaves.

(5) Over pruning and too few leaves for an extended period can delay the growth period and reduce the number of flowers. Moreover, if there is insufficient light indoors during winter and spring, it can cause excessive growth of the plant without flowering, and even formed buds can wither due to insufficient light. Therefore, it is important to provide sufficient light during the winter.
