has two agricultural terms of cold dew and frost in October. During this period, the weather gradually turns cool. Especially after the frost, the Yellow River Basin and the north of China begin to frost. However, at this time, the climate in the South may still be warm, which is still suitable for the growth of all kinds of flowers. Then let the old yellow calendar introduce you to the flower arrangement in October.
in October every year, the climate in northern China and alpine areas has gradually cooled, and early frost may occur, but the south is still cool, warm and pleasant in autumn, with abundant rainfall. It is a suitable season for the growth of all kinds of flowers. Many flower events in September can continue in October. For some cold loving species, the main work in October is still seed collection, sowing, bulb growth, seeding, seedling raising, budding, branching, pot change, etc.and
annual flowers and biennial flowers in October is the season when a large number of seeds mature, which may be the last suitable period for seed collection. Because frost and snow may fall in the north and alpine mountains in November, underdeveloped and dry seeds will suffer freezing damage. The suitable date for autumn sowing ofand
biennial flowers generally lasts from August to November in China, which can be advanced or delayed in some cases. Among the species sown early, such as kale, pansy, calendula, Daisy, etc., it has reached the vigorous growth period in October. It should be placed in a sunny place and fertilized every 10 days or so.and
are all kinds of primroses. Due to the avoidance of strong light, they still need to be placed under the shade shed and apply extremely thick liquid fertilizer once a week or so. For all kinds of seedlings sown in September, they can be planted once or planted separately in October, and should not stay in the seedbed for too long. The planting is generally carried out when there are 2-4 real leaves, and the seedlings planted at one time can be slightly larger.
autumn chrysanthemum the early flowering varieties of autumn chrysanthemum open around October 1, often called National Day chrysanthemum. October is the viewing season, but there are not many varieties of chrysanthemums on national day, and the flower types are not rich. It is not the mainstream of autumn chrysanthemum. Most autumn chrysanthemum periods are concentrated from late October to mid November.and
are blooming autumn chrysanthemums. Since late September, the period of rapid development and increase of flower buds, and the need for fertilizer and water is increasing day by day. Therefore, after the emergence of flower buds, it is necessary to ensure that there is no water shortage and gradually increase the concentration of fertilizer. At least once a week, quick acting fertilizer containing nitrogen, phosphorus and potassium should be applied, and the total concentration of chemical fertilizer can finally be increased to 0. 2％。
stop fertilization immediately when the flower buds begin to develop color. Because the chrysanthemum plant has absorbed less nutrients from the root after the flower bud is colored. Most of the nutrients needed for flower bud development are transferred from leaves. Re fertilization is a waste, and sometimes it will lead to the adverse consequences of withered petals.and
autumn chrysanthemum should have sufficient sunshine at the flowering stage. Under sufficient sunshine, the flower color is more bright. Continuous rain not only makes it difficult to fertilize and spray medicine, but also detrimental to flowering, which may cause mechanical damage and even rot to some varieties with thin and soft petals. Rain prevention at the flowering stage is also a necessary measure, but there should be no water shortage at the flowering stage. The ramet propagation ofand
Paeonia lactiflora Pall was carried out from September to November. Peony mostly blooms in May and withers in October. After the aboveground withered, the last ten days of October was the optimum period for ramets. Early ramets are easy to promote germination and affect the growth of next year; If the ramet is too late, new roots cannot be developed in time due to the decrease of temperature, or the new roots are weak, which will weaken the new plants in the coming year, and even die due to the lack of new roots and drought tolerance. When dividingand
, carefully dig up the whole plant without damaging the root or less, and split the plant cluster with a sharp blade. Each cluster should have 3-5 buds, or 2-3 buds. Pay attention not to hurt the bud, dry it in the shade slightly, and then implant it into the soil after the wound is healed without watering to avoid wound decay. Generally, it is ramet once every 3-6 years.
lupin Lupin is sown in October. Lupin has developed taproot, few fibrous roots and is not resistant to transplanting. It must be broadcast directly, and the plant spacing is 30cm-50cm. It can also reproduce separately in October.
Lotus peony is resistant to cold and heat. The aboveground part withers in summer and autumn, and germinates again after the temperature drops in autumn. In October, dig up the whole plant before the germination of new seedlings, remove the old rotten rhizomes, divide the plant clusters into several small clusters and plant them according to natural sections, or cut the rhizomes into small sections for reproduction, but each section must have bud eyes. Sowing is also carried out in autumn, but it takes 3 years to blossom.and
four seasons Begonia. The suitable growth temperature of four seasons Begonia is 18 ℃ - 20 ℃. October is the suitable growth and flowering season. Sowing or cutting propagation can also be carried out. The seed life is short. The seeds of the current year must be used. The seeds are small and the seedlings are tender. The sowing substrate should be sterilized first. The top branch shall be used for cutting, take root after about 2 weeks and put into the pot immediately. Begonia should overwinter above 10 ℃. Autumn propagation is suitable for overwintering indoors in the South or in winter.
