How do you grow roses so they bloom abundantly with lush foliage? An introduction to common rose colors
Roses are a symbol of love. Every Valentine's Day, these flowers sell especially fast, and many people grow roses in large quantities, so that at a glance along the streets and alleys almost all you see are roses. So what is the secret to growing roses? Let's find out.
How to grow roses so they bloom abundantly with lush foliage
1. Soil
When growing roses, you must choose suitable soil and a suitable growing location for them. Generally, roses grow better when planted in a sunny spot with good ventilation, and the soil is usually neutral or slightly acidic. Suitable soil and environment are the prerequisites for healthy rose growth.
2. Nutrients
When growing roses, you first need to ensure there are sufficient nutrients. At planting time, apply a generous amount of fertilizer as a base fertilizer, and afterward you will also need to apply additional fertilizer. Generally, applying additional fertilizer 4 times a year is enough: once when buds break in early spring, once before flowering and once after flowering, and once before winter arrives. Through these repeated applications of additional fertilizer, the roses' nutrient needs can be met, helping them bloom better.
3. Watering
During the rose growing period, they need to be watered thoroughly. Ground-planted roses should be watered appropriately in early spring and during relatively dry weather. Potted roses need more watering. Generally, during the rose growing season, water once every 2——3 days, and in summer, because evaporation is stronger, water generally every day.
4. Picking flowers
During the rose flowering period, you need to promptly pick flowers that have just opened, because the number of times roses bloom is related to picking the flowers. If you do not pick the flowers, they may bloom only once a year.
What colors are there
1. Red rose
Basically, the red rose is the most common rose. It is a very common cut flower and also a flower used between lovers to express affection. In fact, a true red rose does not exist; the cut flowers on the market are actually Chinese roses (Rosa chinensis), while the red roses in herbal tea are mostly Pingyin roses.
2. Yellow rose
The yellow rose is also a common flower, elegant in form and bright in color, and it is often used to express friendship. In fact, the yellow roses among cut flowers are mostly a type of cut-flower Chinese rose.
3. Purple rose
The purple rose is also a variety of rose. Its flowers are relatively small, but its fragrance is quite strong. The purple rose has many benefits, including beauty care and regulating the human body.
4. White rose
The white rose is also a rose that must not be forgotten. It likes light and is rather afraid of cold. When growing it, it grows better in loose, fertile neutral or slightly acidic soil. In fact, the common white roses among cut flowers are mostly white Chinese roses.
5. Black rose
The black rose is actually the black Chinese rose. There are two common types of black Chinese rose used as cut flowers, and each has its own unique appearance and ornamental value.
6. Green rose
Legend has it that the green rose comes from Israel and is also called Bihai Yuntian. However, a true green rose does not actually exist; the green roses among cut flowers are actually Chinese roses.
7. Orange rose
The orange rose is also a variety of rose, and its flower language is friendship as well as youthful beauty.
8. Blue rose
The blue rose is a genetically modified rose, implanted with a gene that can produce blue pigment, so its petals appear blue.
Blue Enchantress is not a blue rose, but a rose that has been artificially dyed, with white roses dyed blue.
9. Rainbow rose
The rainbow rose is also a type of rose produced by color adjustment, and it too is transformed from the white rose. During cultivation, pigments and dyes are added to the water, and when the petals absorb the water, they become these colorful hues.
The colors of roses all look so dreamy. No wonder they are a symbol of love. These colorful shades are just like love itself, with joy, anger, sorrow and happiness all present.
How to make primroses lush with leaves and abundant in flowers
Primrose is an important ornamental flower for winter and spring. This flower was originally cultivated by a German horticulturist, introduced into our country in 1987, and afterward many excellent varieties were carefully bred by our country's horticulturists. Its flower colors are gorgeous, it has a slight fragrance, and the petals have a velvety sheen. The plant height is 10-15 cm, the leaves are thick and large, the growth is robust, and the cold tolerance is good. It is suitable for planting in both northern and southern parts of our country and is very popular among people.Primrose
Primrose is a perennial herbaceous flower of the genus Primula in the family Primulaceae. The leaves are basal, forming a rosette-shaped leaf cluster; the leaves are long-elliptical, with drooping edges and irregular rounded serrations, and the undersides of the leaves have fine hairs. Flowers or scapes emerge from the plant base, forming either single flowers or umbel-like flowers on the scape, with 5-7 petals. The flowers come in many colors such as red, white, yellow, purple, pink, orange-yellow, peach red, rose red, bicolor and color-changing, and are very gorgeous and pleasing to the eye. The flowers bloom from December to May of the following year, and the ornamental value is extremely high.
How to make primroses lush with leaves and abundant in flowers; based on the author's many years of practical experience growing primroses, attention should be paid to the following care and management tasks:
Sow early and transplant seedlings early. Primroses should be sown in May-June. When the seedlings grow to 2-3 leaves, begin transplanting, and when they grow to 4 true leaves, transplant once more. For transplanting soil, humus soil is best. Because this time is the height of summer, with high temperatures, the seedlings should be shaded and cooled, and a 50% carbendazim 500-800 times solution can be sprayed weekly, with plenty also sprayed onto the potting soil, to prevent stem rot. After two transplants, the seedlings have thick, well-developed root systems and short, sturdy plants, and by September-October they can be divided and potted up.
Apply additional fertilizer frequently. After autumn begins, the weather gradually becomes cooler, and primroses gradually enter a vigorous growth period. At this time, fertilizer and water management should be strengthened, applying a thoroughly rotted, dilute cake fertilizer solution once every 7-10 days. In the early stage, appropriately apply more nitrogen fertilizer to promote plump, strong branches and leaves; in the later stage, appropriately increase the phosphorus fertilizer component, and at the same time spray a 0.3% potassium dihydrogen phosphate aqueous solution onto the leaves every half month, to encourage more buds and flowers, until buds appear.
Water appropriately. Primroses like a moist environment, but should not be overwatered; if the potting soil is too wet, the roots will rot. In summer, improper watering can cause seedling plants to die, so in summer attention should be paid to controlling the amount and frequency of watering. Generally, water once each morning and evening, and when the weather is especially dry and hot around midday, spray water on the plants and the ground around the pots to increase air humidity and lower the temperature, creating a cool, moist climate environment favorable for growth. When autumn turns cool, appropriately reduce the amount and frequency of watering. After being brought indoors in winter, attention should also be paid to appropriate watering as the plants grow and buds and flowers form.
Suitable light. Primroses like light, but avoid strong direct sunlight. In summer during the seedling stage, place the potted plants in a cool, ventilated place with plenty of scattered light. From September onward, the potted plants can receive more scattered light, and from October onward, the potted plants can be placed in full light so they receive more late-autumn light, promoting growth and flower bud differentiation.
Remove flower scapes to encourage more tillering. Primroses are generally best moved indoors to a warm, well-lit place in mid-to-late October. At this time the temperature is suitable, and the seedlings grow rapidly. When the plant grows to 10 leaves, flower scapes will be produced, which can bear more than ten flowers and consume a large amount of the plant's nutrients. To make the plant tiller more and form more buds and flowers, you can remove the first flower scape as soon as it appears, so as to encourage more tillering and expand the plant. In this way, by around the Spring Festival, each pot can produce more than 5 flower scapes, with flowers filling the pot, and the umbel-like inflorescences clustered above the green leaves, colorful and very pleasing to admire.
Control the temperature appropriately. Primroses are somewhat cold-tolerant and do not like high temperatures. In winter, the indoor temperature should preferably be kept at 15-20°C, and maintained at 8-10°C at night. In December, when primroses bloom one after another, the room temperature can be controlled at around 5°C, which can extend the flowering period and add color and splendor to the holiday.
Prevent and control pests and diseases. Common diseases of primroses include leaf spot and stem rot. For the former, spray a 50% zineb 2000 times solution, once every 10 days; for the latter, spray an 80% wettable zineb 500 times solution monthly, and promptly pull out diseased plants. If harmed by red spider mites, spray a 40% dicofol 1200 times solution for control, and at the same time pay attention to ventilation.
How to grow cineraria
Cineraria is a perennial herbaceous plant. The leaves are heart-shaped, large like melon leaves; the flower colors are usually red, light red, white, pink, rose and other colors, as well as colors from sky blue to deep blue, and bicolor varieties with a white center and edges in flesh color, purple, red, white and so on. The petals may be wide, narrow, flat or curled, and single or double, etc. The flowering period is very long.
Cineraria likes warmth and humidity, and avoids heat and dryness. It fears strong light and frost. It requires sandy loam rich in humus, loose and fertile, and well-drained. To make cineraria lush with leaves and abundant in flowers, pay attention to the following aspects:
1. For the potting soil, use a culture soil mixed evenly from leaf mold, garden soil, sandy soil and a small amount of cake fertilizer powder.
2. When the plant grows 5-6 leaves, remove the terminal bud to encourage lateral buds to sprout. Generally keep 3-5 lateral buds per plant and let them grow into flowering branches, which can make the plant shape fuller and the leaves lush and flowers abundant. During the growth period, lateral buds sprouting from the base of the plant should be removed at any time so that nutrients are concentrated.
3. Because cineraria has a relatively large leaf area and needs more water, it must be watered frequently to keep the potting soil moist, to prevent wilting.
4. The flowering time is long and consumes many nutrients, so during the growth process fertilizers need to be replenished in time to ensure continuous blooming with large, brightly colored flowers. The number of fertilizer applications should be determined according to the actual growth situation. If the plant grows slowly and the leaves are pale and thin, apply a light fertilizer once every 10-14 days. If the leaves are spread out and dark green, the number of fertilizer applications can be reduced as appropriate. During the seedling stage, fertilizer should be mainly nitrogen fertilizer, and after winter begins, switch to a liquid fertilizer combining nitrogen and phosphorus, to help promote flower bud differentiation.
5. Cineraria is a light-loving plant. During the growth period, only when placed in a sunny spot can the leaf color be dark green and the flower colors bright; it fears strong light and high temperatures. If exposed to strong direct sunlight, the leaves easily dry and curl; encountering high temperatures easily causes excessive stem and leaf growth, affecting flowering.
6. After summer arrives, attention should be paid to appropriate shading. In midsummer, move the flower pots to a cool, ventilated place to avoid scorching sunlight. At the same time, in summer watering should be sufficient, and it is also necessary to frequently spray water on the plants and sprinkle water on the ground around the flower pots, to lower the temperature and increase humidity. This is beneficial for leaf growth and keeps the leaves upright.
