How long does the blooming period of lilacs last?
An introduction to the blooming period of lilacs and how many times they bloom in a year will surely be helpful to you. Let's learn about it together! Lilacs, scientific name Syringa, are deciduous shrubs or small trees of the Oleaceae family known for their unique fragrance and elegant flowers. The blooming period of lilacs is usually in spring, with specific timing varying by species and climatic conditions, but the blooming period of most species can last for about 10 to 20 days. Some varieties may bloom a second time in early summer, but this is not common.
The length of the blooming period of lilacs is influenced by various factors, including geographical location, climatic conditions, and planting environment. In temperate regions, lilacs usually bloom between April and June, while in warmer areas, the blooming period may start as early as March or extend to July. Moreover, the blooming period of lilacs is also affected by temperature, with warm springs possibly advancing the blooming period, and cold springs delaying it. How many times lilacs bloom in a year mainly depends on the species. Most lilac varieties bloom only once a year, but a few can bloom twice. These twice-blooming varieties usually bloom again in early summer after appropriate pruning and care following their spring blooming. However, this second blooming is not common and the number of flowers and fragrance may be less than that of the first spring blooming. Here are some common lilac varieties and their blooming period characteristics: 1. Common lilac (Syringa vulgaris): This is the most common lilac variety known for its purple flowers. The blooming period of common lilac is usually from April to May, lasting about 10 to 15 days. 2. White lilac (Syringa alba): This variety has white flowers and a blooming period similar to that of the common lilac, from April to May, lasting about 10 to 15 days. 3. Meyer lilac (Syringa meyeri): Meyer lilacs have light blue flowers, a slightly later blooming period, usually from May to June, lasting about 10 to 20 days. 4. Persian lilac (Syringa persica): This variety has light purple flowers, blooming from May to June, lasting about 15 to 20 days. 5. Double lilac (Syringa chinensis): Double lilacs have white or light purple flowers, blooming from May to June, lasting about 15 to 20 days. 6. Twice-blooming lilac varieties: Although not common, some varieties like 'Katherine Havemeyer' and 'Charles Joly' can bloom twice a year with appropriate pruning and care. To extend the blooming period of lilacs, the following measures can be taken: 1. Proper pruning: After lilacs bloom, pruning dead and diseased branches in a timely manner can promote the growth of new branches and help extend the blooming period. 2. Sufficient sunlight: Lilacs enjoy plenty of sunshine, ensuring the plants receive adequate sunlight helps with flower opening and fragrance release. 3. Appropriate watering: Keeping the soil moist but not waterlogged helps the plant's growth and extends the blooming period. 4. Reasonable fertilization: Fertilizing appropriately in spring and summer can provide the necessary nutrients for the plants, helping with flower growth and extending the blooming period. 5. Pest and disease control: Timely pest and disease control can protect the plant's health and help extend the blooming period. In summary, the blooming period of lilacs is usually in spring, lasting about 10 to 20 days, and most varieties bloom only once a year. Through appropriate pruning, lighting, watering, fertilizing, and pest and disease control measures, the blooming period of lilacs can be extended. However, twice-blooming lilac varieties are not common and require special care and management.
