FLS005 Colorful Roses Seed (200 seeds/bag)

·      This pack contains 200 seeds of colorful roses. These seeds come from different - colored rose varieties. They are oval - shaped, mostly dark brown in color, with fine textures on the surface. Rose is a perennial woody flower. The plant has diverse forms, with different growth habits such as upright and spreading. There are usually prickles on the stems. The leaves are odd - pinnate compound leaves, and the edges of the leaflets have serrations. The roses grown from these seeds have rich flower colors, covering various colors such as red, pink, yellow, and white. The flowers are generally double - petaled, with layers of petals overlapping each other, having a beautiful flower shape. The diameter is usually between 5 - 15 centimeters, and they emit a charming fragrance. Roses not only have extremely high ornamental value and are often planted in courtyards, parks, and other places for beautifying the environment, but also in the field of floral art, they are important materials for making flower bouquets and flower - arranging works. At the same time, their flowers can also be used to make rose tea, rose essential oil, and other products, with a wide range of uses.

1. Soil preparation: Select loose, fertile, well - drained soil that is slightly acidic to neutral, with a pH value of 6.0 - 7.0 being appropriate. Mix leaf mold, garden soil, and perlite in a ratio of 3:2:1 evenly and put it into a seed - raising pot or planting container. Before filling the soil, lay a layer of broken tiles or ceramsite at the bottom of the container to enhance drainage performance. Then water it thoroughly to make the soil in a moist but not waterlogged state.

2. Seed treatment: To improve the germination rate, soak the seeds in warm water for 4 - 6 hours to allow the seeds to fully absorb water. After soaking, take out the seeds, wrap them with a damp cloth, and place them in a warm (20 - 25℃), well - ventilated place for germination. Rinse them with clean water once a day. After about 2 - 3 days, when some seeds show white, they can be sown.

3. Sowing operation: Since the seeds are small, mix the seeds evenly with an appropriate amount of fine sand and then evenly sprinkle them on the soil surface. Try to make the seeds evenly distributed, keeping the seed spacing at about 2 - 3 cm to avoid overcrowding. After sowing, cover a thin layer of soil about 0.5 cm thick, and then gently compact the soil to make the seeds closely contact the soil.

4. Moisture and light preservation: After sowing, use a sprayer to gently spray water to keep the soil moist. Cover a layer of plastic film or plastic wrap on the seed - raising pot or planting container to maintain humidity and temperature. Place it in a brightly lit place but avoid direct sunlight. The suitable germination temperature is 18 - 22℃. Open the film for ventilation for 1 - 2 hours every day to prevent the seeds from mildewing due to excessive humidity.

5. Management after emergence: Generally, the seeds begin to emerge about 7 - 10 days after sowing. After emergence, remove the covered film in time and gradually increase the light duration, but avoid direct strong light to prevent burning the seedlings. Keep the soil moist, following the principle of "watering when the soil is dry". That is, when the soil surface is dry 2 - 3 cm, water it, and water thoroughly each time. When the seedlings have 2 - 3 true leaves, thin out the seedlings, remove the weak and over - dense seedlings, and keep the strong seedlings to provide sufficient growth space for them. When the seedlings have 4 - 5 true leaves, they can be transplanted into a larger flowerpot or planting area. Try to transplant with soil clumps to protect the roots of the seedlings.

a. Temperature requirements: The germination of rose seeds and the growth of seedlings are relatively sensitive to temperature. If the temperature is too low, the seeds germinate slowly or do not germinate at all; if the temperature is too high, the seedlings are prone to spindly growth and weakness. When sowing in early spring or late autumn, take heat - preservation measures, such as covering with plastic film; in high - temperature summer, pay attention to shading and cooling to avoid the excessive temperature from affecting seed germination and seedling growth.

b. Light management: Roses need sufficient light for photosynthesis, but in the initial stage of seed germination and the seedling stage, too strong direct light will damage the seedlings. After emergence, gradually increase the light duration, but in the high - temperature period of summer, especially at noon, appropriate shading is required to avoid direct strong light. As the plant grows, the light intensity can be gradually increased to promote the robust growth and flower bud differentiation of the plant.

c. Water control: From sowing to emergence, keep the soil moist, but there should be no waterlogging, otherwise the seeds are easy to rot. After emergence, water the plants reasonably according to the dry - wet condition of the soil. Avoid over - watering, which may cause root hypoxia and rot, and also prevent the soil from being too dry, which will affect the growth of the plants. Generally, water when the soil surface is dry 2 - 3 cm, and water thoroughly.

d. Fertilization points: In the initial stage of rose seedling growth, a small amount of thin nitrogen fertilizer can be applied appropriately to promote the growth of the plant's stems and leaves. When the plant grows to a certain stage and enters the vigorous growth period, the application amount of phosphorus - potassium fertilizer, such as potassium dihydrogen phosphate solution, should be increased to promote the branching of the plant and flower bud differentiation, and improve the flower quality. When fertilizing, pay attention to applying thin fertilizers frequently to avoid burning the roots with concentrated fertilizers.

e. Pest and disease control: Common pests and diseases of roses include powdery mildew, black spot, aphids, red spiders, etc. Keep the planting environment well - ventilated, regularly clean up diseased leaves and plants, and reduce the breeding environment of pests and diseases. Regularly check the plants. Once pests and diseases are found, take corresponding control measures in a timely manner. For powdery mildew and black spot, fungicides such as carbendazim and chlorothalonil can be used for spray control; for aphids and red spiders, insecticides such as imidacloprid and abamectin can be used for control.
