First, the suitable sowing time of Dianthus multicolored.
The time of sowing carnation is not certain, because there is a big difference in climate and temperature between the north and the south, so we should look at the temperature rather than the time when sowing. The most suitable temperature for the germination of carnation seeds is 21~ 22℃, which is generally in spring and autumn.
As for when to plant the colorful Dianthus caryophyllus, it depends on the actual situation. Even the colorful Dianthus caryophyllus planted in spring will only grow leaves in that year and will not bloom until the following year. Moreover, the colorful Dianthus caryophyllus is cold-resistant and heat-resistant, so the best sowing time is generally September ~10 in autumn.
Second, the method of planting Dianthus multicolored 1, and the preparation of pot soil
First, prepare pot soil for sowing. The size of flowerpot depends on the number of sowing, and the soil is preferably fertile and loose sandy soil, which can be mixed with peat soil, fine sand and vermiculite. Before sowing, disinfect the soil.
2, reasonable sowing
Because the seeds of Dianthus multicolored are very small, a thin layer of soil can be properly covered on the seeds after sowing to prevent the seeds from being blown away. Then irrigate enough water to keep the soil moist.
3, curing emergence
After sowing, move the pot soil to a ventilated place with scattered light for maintenance, keep the pot soil moist, control the temperature at about 2 1℃, and the seedlings can grow in about 10 days. It can be cultivated directly in flowerpots, or transplanted after the seedlings of Dianthus multicolored grow to 4-5 leaves.
Third, the maintenance skills of carnation 1, appropriate watering
When watering carnation, we should follow the principle of not watering it, but pouring it thoroughly. Carnation is afraid of waterlogging, especially if there is no water in the basin, otherwise it will easily lead to root rot. There is no fixed number for watering in the four seasons. When watering at ordinary times, just keep the basin soil slightly moist, and pay more attention to observing the situation of the basin soil.
2. Appropriate lighting
The growth of colorful carnation needs plenty of sunshine. If it is a potted plant cultivated indoors, it is best to put it on the balcony or other sunny places for maintenance, and keep the light for more than ten hours every day to make it bloom better and earlier. If it is shaded for a long time, it will lead to excessive branches and leaves, few flowers or even no flowers.
3. Rational fertilization
Dianthus multicolored does not have a high demand for fertilizer, and thin fertilizer water can be applied every other month during the growth period, and the fertilizer is mainly nitrogen fertilizer. Apply more phosphorus and potassium fertilizer before the flowering period of Dianthus colorata to promote the differentiation of flower buds and improve the quality of flowering.
4, appropriate pruning
During the growth of Dianthus multicolor, it needs to be pruned properly. Besides pruning some dead branches and diseased branches, after flowering, the residual flowers should be pruned in time, which can save nutrients and continuously promote the opening of new flowers.
Conclusion: After reading the above contents, I believe everyone should know the suitable time for planting carnation. It is best to choose autumn sowing, and the autumn environment is more suitable for the germination and growth of carnation, and it will bloom in the next year.
