What are the precautions for sowing verbena?
1. Select fresh seeds
Choose fresh seeds, not old ones.
2. Proper sprouting
Before sowing, stratification and sprouting can be carried out to improve the germination rate.
3. Low soil requirements
Loose, fertile soil is best, but ordinary soil will also do.
4. Water appropriately before sowing
Watering before sowing should be moderate; do not let the soil become completely soaked, as this is not good for the growth of fine-leaf verbena.
5. Careful care
After sowing, careful care is needed, with appropriate watering and fertilizing and suitable light.
Now everyone knows the sowing time and precautions for verbena, right! Verbena flowers are small and lovely, with strong vitality. The cultivation method is also relatively easy. Friends who like verbena might as well sow in spring and autumn according to these precautions and take careful care of them!
When is verbena sown? Management after sowing verbena
Verbena is planted in groups at park entrances, in square flower beds, in roadside planting troughs and along lawn edges, fresh and pleasing to the eye, full of a natural and harmonious atmosphere. So, when is verbena sown? How should it be managed after sowing?
Verbena is often sown in autumn after mid-to-late September: Disinfect the substrate - disinfect the substrate used for sowing; the best method is to put it in a pot and heat it by stirring, and any diseases and pests will be scalded to death. Sprouting: soak the seeds in warm hot water (about the same temperature as face-washing water) for 3 to 10 hours, until the seeds absorb water and swell. For very common seeds that germinate easily, this step can be skipped.
Sowing verbena: For tiny seeds that are difficult to pick up with hands or other tools, you can moisten one end of a toothpick with water, stick the seeds one by one onto the surface of the substrate, cover with substrate 1 cm thick, then place the sowing pot into water, with the water depth at 1/2 to 2/3 of the pot height, and let the water slowly soak up (this method is called the "pot soaking method"); for larger seeds that can be picked up with hands or other tools, place the seeds directly into the substrate and sow them in spots at a spacing of 3 x 3 cm. After sowing, cover with substrate, with a covering thickness of 2 to 3 times the seed size. After sowing, use a sprayer or a fine-holed watering can to wet the sowing substrate, and later when the pot soil is slightly dry, water again, still taking care that the force of watering is not too strong, so as not to wash the seeds away.
Management after sowing verbena: After sowing in autumn, when encountering a cold wave and low temperatures, you can wrap the flower pot with plastic film to help keep it warm and moist; after the seedlings emerge, uncover the film in time, and let the seedlings receive sunlight before 9:30 every morning, or after 3:30 in the afternoon, otherwise the seedlings will grow very weak; after most of the seeds have emerged, appropriate thinning is needed: pull out the diseased and unhealthy seedlings so that the remaining seedlings have a certain amount of space between them; when most of the seedlings have grown 3 or more leaves, they can be transplanted into pots.
Verbena has a short, dense plant cluster, a long flowering period, and abundant, brightly colored flowers. It is suitable for pot cultivation and hanging basket cultivation, decorating windowsills, balconies and corridors, bright and elegant, full of charm. And through the above introduction, everyone should now understand the sowing method of verbena and the management after sowing!
Verbena planting methods: precautions for verbena cuttings
Verbena is also known as grass five-color plum, creeping verbena, creeping brocade, four-season hydrangea, etc. It is a perennial herbaceous plant of the genus Verbena in the Verbenaceae family, native to South America. It can be used as flower bed and flower border material, and can also be grown as pot flowers in large areas in places suitable for potted ornamental display or for arranging flower terraces, garden gaps and tree beds. Now let us take a look at the cultivation methods of verbena!
Growth habits of verbena
Verbena likes sunlight and is not tolerant of shade; it is relatively cold-tolerant, has poor shade tolerance, and is not drought-tolerant. In the north it is mostly cultivated as an annual herbaceous flower, and it can bloom normally in hot summers. It grows in sunny, loose and fertile soil and blooms profusely. It likes a warm and humid climate, likes sun, and is not drought-tolerant. It has low soil requirements, but in loose, fertile, relatively moist neutral soil it can root at every node, grow robustly, and bloom profusely. In Shanghai, in places with a relatively warm microclimate, it can overwinter in the open ground.
Propagation methods of verbena
1. Sowing: The germination rate of verbena seeds is relatively low, only about 50%, and germination is very slow and uneven. At a temperature of 15 to 17°C, it takes 2 to 3 weeks to begin emerging. The sowing time is mostly in spring. After the seeds are sown, they should be placed in a dark place, and not only should the soil be kept moist, but the air should also be kept humid. When watering, do not water directly from top to bottom; use a shallow pan or other container to hold water 3 to 4 cm deep, then immerse the flower pot in it, letting the water enter through the drainage hole at the bottom of the pot, and take it out after the soil is moist, otherwise the germination rate will be even lower.
2. Cuttings: Verbena cuttings can be taken in May to June, when the temperature is around 15°C. First take slightly woody branches, cut them into 5 to 6 cm long sections as cuttings, insert them into a moist sand bed, then shade them immediately. After 2 to 3 days, they can receive a little morning and evening sunlight to promote growth. After about two weeks, they can sprout new shoots and take root. When the seedlings grow 5 to 6 true leaves, transplant them, and when they grow to 7 to 8 cm, plant them in their final position.
Cultivation methods of verbena
1. Soil: Verbena has low soil requirements, but in loose, fertile, relatively moist neutral soil it can root at every node, grow robustly, and bloom profusely.
2. Watering: Because verbena has a relatively shallow root system, attention should be paid to watering in summer to prevent drought. During the maintenance period, too much or too little water is not good for growth. With too much water, the stems become slender and spindly, and the number of flowers decreases; with a lack of water, the plant grows and develops poorly, and there will be a phenomenon of early seed setting.
3. Sunlight: In spring, summer and autumn, verbena needs to be maintained under shaded conditions. When the temperature is relatively high, if it is placed in direct sunlight for maintenance, the leaves will noticeably become smaller, the internodes of the branches will shorten, the lower leaves will turn yellow and fall off, and growth will be very slow or it will enter a semi-dormant state.
4. Temperature: Verbena likes a warm climate and avoids intense heat. When the summer temperature is above 34°C, growth is clearly poor. It is not tolerant of frost and cold, and when the winter temperature is below 4°C, it enters dormancy or dies. The most suitable growth temperature is 15 to 25°C. It is generally sown in autumn and winter to avoid the high temperatures of summer.
5. Fertilizing: Like other herbaceous flowers, verbena has a relatively high demand for fertilizer and water, but the fertilizing (watering) principle of "light fertilizer applied frequently, small amounts more often, complete nutrition" should be followed, and after fertilizing, the leaves and flowers should be kept dry at night.
6. Pruning: Before flowering, verbena is generally pinched back twice to encourage more flowering branches to sprout.
