When will a bunch of red blossom? The planting method with pot planting!

A string of red herbs are labial herbs, which blossom continuously from late summer to late autumn, and are less likely to wither. A string of flowers are fiery red, spread all over the floor, like crackling firecrackers on the ground during the Spring Festival. So when will a bunch of red blossom? The planting method with pot planting!

When will a string of red blossom

1. The florescence of a string of red

A string of red blossoms are popular, which are more common festive flowers. The viewing period is very long, and usually the flowers can bloom from summer to autumn. Naturally, the florescence of a string of red flowers is from May to November, but if properly controlled during the breeding period, it can be a string of red flowers in the four seasons.

two。 Florescence control of a string of red

When controlling the florescence of a string of red, the most common methods are heart-picking and short-day treatment, as well as controlling the time of sowing.

Coring can run through a string of red growth, generally in a string of red plant height 20cm can be carried out when the coring, can promote its branches, in the branch growth period of time in the second coring, can make the plant short and strong, luxuriant branches, if in late August once, can be in the National Day when flowering.

Short-day control can promote the differentiation of a bunch of red flower buds, sowing early in spring, short sunshine time, which is beneficial to growth, but if the planting time is relatively late, short-day treatment is needed. specifically, shading in the morning and evening, sunshine about 8 hours a day can blossom faster.

Controlling the sowing date of a string of red seeds can control the time of flowering. If sowing in late August and potting in November, it can blossom on May Day if the light and temperature are right. Sowing in spring and picking hearts many times can make it blossom on National Day.

In addition, it can also make a string of red seasons bloom. if the inflorescences are all removed, then the flowers can bloom after 25 days. Attention should be paid to strengthening the management of water and fertilizer, and giving adequate light and temperature. If 0.2% potassium dihydrogen phosphate can be foliar sprayed, the flower color will be more colorful.

2. The planting method of a bunch of red potted plants

1. Control light and temperature

After planting a bunch of red, put it in a cool place for 3 days to slow down the seedlings. Then put it in the sun to ensure sufficient light. To facilitate the control of light intensity, a suggested scaffolding can be built above the flowerpot. Shade 50% when the light is too strong, especially at noon in summer. Once at a low temperature, it is necessary to put on a plastic film for proper heat preservation, which can usually be done at night or on rainy days.

two。 Maintain moisture and humidity

A string of red likes a humid environment and should be sprayed with water once a day, except on rainy days. When watering, the difference between ground temperature and water temperature should not exceed 5 ℃. When the temperature is high, water is often sprayed to the surrounding environment to lower the temperature and increase the humidity of the air. Clean the branches and leaves regularly to improve photosynthesis, once every 15-20 days.

3. Give priority to extra-root topdressing

Soil provides an important guarantee for the growth and development of flowers, but does not guarantee the healthy growth of plants. It is far from enough to rely on a little water, fertilizer and air in the soil. The specific methods are as follows:

After potted for a week, fertilize outside the root once. Spray once a day for the next three days. The fertilizer was mixed with urea plus potassium dihydrogen phosphate and a small amount of calcium superphosphate. The spraying time is in the early morning and evening.

After that, watering was combined with fertilization, and extra-root fertilization was carried out 8-12 hours after watering. Note that it can be applied around in windy days or in strong light.

4. Control the date of flowering

When sowing in different seasons, the flowering time is also different. Sow in spring and blossom in autumn; sow in greenhouse in autumn and blossom from April to May the following year. The florescence can be controlled in the following ways during flowering:

Cutting off the branches of the buds in time can postpone the flowering period appropriately.

After each flower failure, pick off the residual flowers in time, strengthen the water and fertilizer management, a string of red can re-branch and blossom, prolong the flowering period.

5. Timely pruning and topping

Potted plants need to top 3 times after transplanting to inhibit their growth and promote the germination of lateral buds. The plants grown in this way are short and strong, and there are more flower heads.
