How to Propagate Primroses? Detailed Methods and Precautions
Primrose, also known as cuckooflower and Qichonglou, has become increasingly available in more colors in recent years due to its development, and its bright blooms are very appealing. Primroses like warmth and tolerate cold slightly; when primroses are cultivated artificially, fertilization needs to be reduced during their full bloom period.
Primrose
Primrose seeds are harvested when the capsules begin to turn yellow, dried in the shade, and must not be exposed to the sun. After drying, remove the seed shells and store. Primroses are commonly propagated by sowing. The seed germination rate is 40%, and seeds kept for over a year rarely germinate. The seeds are tiny and not easy to collect. In China, from south to north, around March to May, when the primroses in the pot are blooming, loosen the potting soil and let the seeds fall into the pot on their own. If the original pot is relatively small, you can collect the seeds and sow them. The seeds can be sown in a large pot used as a seedbed. Use the bottom-watering method to soak the potting soil thoroughly, cover with glass, and provide slight shade. The suitable germination temperature is 15°C to 20°C, and seedlings emerge in 5 to 6 days. After emergence, remove the glass to avoid leggy seedlings. The seedlings need to be thinned out every half month. In summer, pay attention to shading, ventilation, and maintaining appropriate dryness. By early September, when the seedlings have produced true leaves, pricking out and potting up can be done. Sowing can also be done from August to September; management is more convenient, but the plants grow shorter.
Some double-flowered primrose varieties often do not easily produce seeds, so they can only be propagated by cuttings or division. Cuttings are taken from May to June, while division is best done in autumn. Common indoor potted primrose pictures. After the seedlings are potted up and have established, gradually let them receive sunlight and apply thin fertilizer. After late October, move the pots indoors to a sunny spot. From November onward, they will bloom successively. Primroses are relatively tolerant of low temperatures and can overwinter at 0°C. If the room temperature is maintained at 5°C to 10°C and attention is paid to ventilation, they will produce abundant flowers and lush leaves. Around New Year's Day, flower stems are produced and flowering begins, entering full bloom at Spring Festival. After the flowers fade, cut off the spent flower stems, and new flower stems can be produced to continue blooming. When flowering ends and the weather gradually becomes hot, they should be moved to a cool, ventilated place and kept moist, not too dry. After a semi-dormant period, repot from September to October, and they can still bloom in winter. If kept in a 10°C to 12°C environment in summer, they can also bloom as usual. The key maintenance points for primroses are: after the seedlings emerge, when they grow to 5 true leaves, transplant them into small flower pots with a diameter of 10 cm, and a small amount of bone meal or decomposed cake fertilizer powder should be applied at the bottom of the pot. When the seedlings reach a certain height, plant them in flower pots with a diameter of 16 cm. For the potting soil, use a cultivation soil of 7 parts leaf mold and 3 parts garden soil, with a small amount of base fertilizer added. When first potting up, pay attention to providing appropriate shade. About 10-15 days after the seedlings have recovered, apply 1 time a dilute liquid fertilizer combining nitrogen and phosphorus or a compound chemical fertilizer. During the growing period, water according to the principle of "dry before wet," avoiding water accumulation in the pot. After the flowers fade, promptly cut off the spent flowers and apply 1-2 times thin fertilizer to promote the growth of new flower branches, so that flowering can continue. Primrose seedlings are weak and highly susceptible to damping-off, which causes the seedlings to rot and die, so early prevention and control should be noted. To grow primroses well and keep them blooming continuously, pay attention to: separate planting and transplanting. When the sown seedlings grow 2-3 true leaves, first plant them separately in small pots, cultivate for about 1 month, then transplant them into medium pots. Fertilization and watering.
How to Grow Primroses: Cultivation Methods and Precautions for Primroses
Primrose, also known as cuckooflower, is a plant of the genus Primula in the family Primulaceae. It mostly grows in wild fields and along field edges, and is native to Yunnan and Guizhou in China; it is cultivated in various places and is quite ornamental. Primrose is a kind of flower and grass people often see, and is one of the plants with ornamental value, often used to beautify the home environment. Many people do not know how to grow primroses. This article introduces the cultivation methods and precautions for primroses.
Growth Habits of Primroses
Primrose is a typical warm-temperate plant. The vast majority of species are distributed in higher latitudes at low altitudes or lower latitudes at high altitudes. It likes cool, humid climates and well-drained soil rich in humus. It is not tolerant of high temperatures or strong direct sunlight, and most are also not tolerant of severe cold.
Primroses generally used as cool greenhouse pot flowers, such as Primula obconica and Primula sieboldii, are suitable for cultivation in neutral soil. They are not tolerant of frost and have an early flowering period. The European primrose (Primula vulgaris), used for open-ground flowerbed arrangements, is suitable for growing in shady slopes or semi-shady environments and likes well-drained soil rich in humus.
Cultivation Methods for Primroses
1. Soil: For potting soil, use a cultivation soil of 2 parts leaf mold and 1 part garden soil, with a small amount of base fertilizer added. This cultivation soil is loose and fertile, mostly slightly acidic, which benefits root development.
2. Light: Primroses like light but avoid strong 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. 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.
3. Temperature: Primroses like warmth and tolerate cold slightly. The suitable growth temperature is about 15°C. If the indoor temperature in winter is maintained at 10°C, they can overwinter above 0°C. In summer, the temperature must not exceed 30°C; they fear strong direct light, so shade and cooling measures should be taken.
4. Watering: Primroses like a humid environment, but should not be watered excessively; if the potting soil is too wet, the roots will rot. In summer, improper watering can cause seedling plants to die, so in summer pay attention to controlling the amount and frequency of watering. Generally, water once each in the morning and evening every day. When the weather is especially dry and hot around noon, spray water on the plants and the ground around the pots to increase air humidity and lower the temperature, creating a cool, humid climate environment conducive to their growth. When autumn becomes cool, appropriately reduce the amount and frequency of watering. After moving indoors in winter, attention should also be paid to appropriate watering as they grow and produce buds and flowers.
5. Fertilization: After the seedlings have recovered, apply 1 time every 10 days a dilute liquid fertilizer combining nitrogen and phosphorus or a compound chemical fertilizer. After autumn begins, the weather gradually becomes cooler, and primroses gradually enter a vigorous growth period. At this time, strengthen fertilizer and water management, applying 1 time every 7-10 days a fully decomposed dilute cake fertilizer liquid. In the early stage, appropriately apply more nitrogen fertilizer to promote plump and strong branches and leaves; in the later stage, appropriately increase the phosphorus fertilizer component, and at the same time spray the leaves with a 0.3% potassium dihydrogen phosphate aqueous solution once every half month to promote more bud formation and flowering, until buds appear.
6. Pests: Primrose seedlings are weak and highly susceptible to damping-off, which causes the seedlings to rot and die, so timely spraying for prevention and control should be noted. If the disease has already occurred, take a small amount of 70% Dexon original powder and mix it with 40 times fine sandy soil and apply it into the potting soil, or prepare an 800-fold solution and spray it on the soil surface; both have good control effects.
7. Pruning: During the flowering period, select plants that have just set seeds, remove part of the flower branches, and apply 1-2 times more dilute liquid fertilizer mainly based on phosphorus fertilizer, so that the seeds are plump and full. After the flowers fade, promptly cut them off and apply 1-2 times thin fertilizer to promote the growth of new flower branches, so that flowering can continue.
Primrose is a flowering plant that blooms in early spring. Its colorful flowers in red, pink, yellow, white, purple, and more are very beautiful. The flower posture of low, compact potted plants is exquisite and lovely, and it is one of the flowers commonly used to decorate the home. The cultivation methods and precautions for primroses are introduced here; we hope this is helpful to everyone.
Cultivation Methods and Precautions for Primroses
Primrose is a flower plant unique to China, mainly distributed in Yunnan, Guizhou, and other places. Primroses bloom in early spring, have rich flower colors and a long flowering period, and are very suitable for potted appreciation. So how do you cultivate primroses? Next, let's learn about the cultivation methods and precautions for primroses.
I. Growth Habits of Primroses
Primroses like warmth and are slightly tolerant of cold. The suitable growth temperature is about 15°C. If the indoor temperature in winter is maintained at 10°C, they can bloom from February of the following year. Pay attention to ventilation; they can overwinter above 0°C. In summer, the temperature must not exceed 30°C; they fear strong direct light, so shade and cooling measures should be taken. Spent flowers should be cut off in time. During flowering, in order to prolong the viewing period, temperature and light should not be too high. After the flowers fade, to keep them blooming continuously, promptly cut off the spent flowers and stems and apply additional fertilizer, while promoting renewed growth and flowering. During the growing period, the potting soil should be kept moist, not too dry or too wet, and at the same time apply 1 time every 10 days a liquid fertilizer mainly based on nitrogen fertilizer; during the bud stage, apply 2-3 times a liquid fertilizer mainly based on phosphorus fertilizer. During the full bloom period, reduce fertilization, and stop fertilization after the flowers fade. Before fertilizing, stop watering and let the potting soil be somewhat dry to facilitate fertilizer absorption. When fertilizing, be careful that the fertilizer water does not contaminate the leaves; you can spray water once after fertilizing. Temperature and light.
