Culture skills of tricolor whorl

I. planting environment

This kind of plant is usually cultivated for a year, and most of it is creeping. Because of its appearance and habits, it is very suitable for decoration of fences or for covering slopes. In addition, fences and brackets are also good choices. If you like, you can also transplant it into a flowerpot and use it as a potted plant or flower bed decoration.

2. Soil

Tricolor whorl is not very strict on the soil and can be planted directly with seeds or plants. During the plant growth period, in order to prevent the plant from lodging during the growth process, you can support the plant by supporting several pillars in the flowerpot, or simply use a hanging pot to plant it so that its branches can droop and grow like a hanging orchid. In addition, in the process of breeding, the soil should be kept in a state of slight tide in case the plant is short of water, but also be careful not to have stagnant water.

Third, temperature

Tricolor flowers can grow healthily in spring, summer and autumn. Early spring or early spring is the best time to sow seeds, when the temperature should be maintained between 18-25 degrees, usually about 1-2 weeks, the seeds will germinate. When it is hot in summer, it is best to put the plant in a ventilated and cool position for maintenance, and do not put it in the sun, it is best to put it in a position that can accept astigmatism, so as to prevent the leaves of the plant from burning.

4. Moisture

Tricolor flowers like a wet environment, so the soil should always be kept in a moist state, and give the plant sufficient water, and be careful not to let the soil dry, which is not conducive to plant growth.

5. Fertilizer

Tricolor flowers usually blossom about 70-90 days after sowing, because flowering consumes a lot of nutrients, so it should be given sufficient nutrients before flowering, usually one month to half a month before flowering. Fertilizer should be applied every 14 days to ensure plant growth and nutrient accumulation. In order to ensure the normal flowering of the plant.

6. Pruning

Pruning is also a necessary step in order for plants to grow better. Especially in the growth period, plants grow too fast and are easy to lodge. In addition to column fixation or hanging basin culture, plants can also be properly pruned to reduce the number of messy branches. The number of times is not too much, as long as it is appropriate.

Tricolor spiral flower is not very difficult to raise plants, as long as you are in the maintenance, more careful, tricolor spiral flower will be able to bloom brilliant!

The cultivation technique of tricolor spiral flower can be cultivated with organic patch culture soil. during the growth period, the soil should be kept moist and should not be made dry, and it should be placed in a place with plenty of light outdoors. It will blossom after about 70-90 days after sowing. It can be fertilized one to one and a half months before flowering, once every two weeks, to increase the fertility of flowering and make the flowers bright. The branch has a trailing nature, so when the stem branch is elongated during the growth period, it can be moderately trimmed and propped up to prevent lodging, and it can also be planted in the hanging pot or flower bed, allowing it to droop and grow, which is also a good choice. Although the heat tolerance of tricolor Chaoyan is good, when the hot summer comes, the muggy weather is easy to weaken the plants, so it is necessary to maintain the ventilation of the cultivation environment; and the evapotranspiration is relatively fast, so it is necessary to pay attention to the supply of water, but the cultivation medium used needs to be well drained so as not to make the roots rot easily in hot and humid conditions. And its cold tolerance is also good, so the cultivation period can be extended to early autumn. Most of the propagation methods of tricolor spiral flowers are propagated by sowing method, and the sowing time is about from early spring to early summer, and the optimum temperature for germination is about 18: 25 ℃. It can be sown in the seedling tray, covered with thin soil, keep the soil moist, and can be covered with transparent plastic sheet on the seedling plate to maintain moisture, but the plate can not accumulate water, and it can germinate in about 7 to 14 days. At this time, the plastic sheet can be removed and placed in a place with bright light, waiting for 3 leaves. Can be transplanted in the basin, but the tricolor facing the face of the seedling is not resistant to transplantation, so the transplantation should be careful, it can also be broadcast in the basin from the very beginning.
