Can Althaea be planted in summer?
Compared to what most people know about whether Althaea can be planted in summer and the green plant and flower aspects of Althaea planting methods and timing, let's follow the editor to see the specific content!
Althaea is native to Sichuan Province, China, and is also known as a丈red, chessboard flower, big Althaea, and Weizu Althaea. Althaea seeds are usually planted in spring and autumn, and the plants that are sown in summer will bloom in the following year. Althaea is a biennial herbaceous plant, with a blooming period from June to August, and it can bloom continuously for 3 months. Below is a detailed introduction to how long Althaea can bloom after sowing in summer and the sowing methods.
I. Bloom Time After Sowing in Summer
Althaea seeds mature in August or September and remain viable for 4 years after harvest. The germination temperature for Althaea seeds is between 15 and 30°C. Under favorable weather conditions, they can germinate about a week after sowing. The seeds sown in summer are from previous harvests, and they will not bloom in the same year. Seeds sown in early summer can grow vigorously in a temperature range of 25 to 30°C, but they will not bloom in autumn and will bloom in June of the following year.
II. Althaea Sowing Methods
1. Sowing Time
In southern regions, sowing is mainly done in autumn, while in the North China region and further north, sowing is usually done in spring. In the North China region, plants sown in spring can bloom by summer. However, in the Northeast, if you want to bloom in summer, you need to start with indoor or outdoor film mulching seedlings before transplanting. In southern regions, Althaea seeds can be sown in the same year they mature.
2. Seed Germination
After harvesting, the seeds should be cleaned in clear water to remove impurities, then soaked in warm water until they swell, after which they are taken out and disinfected, and then dried in a cool, well-ventilated place.
3. Soil Selection
Suitable for sowing is fertile, deep, well-drained, and aerated sandy soil. A mixture of decomposed leaf soil and peat soil can be prepared, and a base fertilizer should be applied.
4. Sowing Process
Althaea can withstand cold and can be grown by indoor sowing or direct sowing in the field. When sowing, place the seeds in small holes and cover them with a thin layer of fertile fine soil. For spring sowing in the field, a layer of plastic film needs to be covered, with small holes pierced in the film to maintain a suitable temperature.
5. Post-Sowing Care
After sowing, the plants need ample direct sunlight and moist soil. Generally, they can germinate within 7 to 15 days. Once the seedlings have grown 3 to 5 true leaves, they can be transplanted and planted.
