How to cultivate and manage Central Plains Peony in different months?

January

From the first ten days of January (slight cold) to the last ten days of January (severe cold): The weather is cold, and the peony is in a dormant state, so pay attention to cold protection and overwintering, and you can accumulate fertilizer during this period.

February

The monthly average temperature is 1.11℃; 5 cm ground temperature is 2.32℃, and 15 cm ground temperature is 4.33℃.

beginning of spring: It's still cold.

Late February (rain): The soil thaws and the roots move faster. The upper scale buds began to sprout and expand. At this time, I began to hoe the ground and finished hoeing in early March. The seedlings of the seeds began to sprout, and the plastic film on the seedling bed and the attached soil above the mark were scraped off, and only 3.3 cm thick soil was eaten on the seeds.

in March

the monthly average precipitation is 18.8mm; The monthly average temperature is 5.88℃; The ground temperature is 6.55℃ for 5 cm and 7.83℃ for 15 cm.

in the first ten days of March (startled sting), the scales sprout, and in the middle of March, the leaves show buds. Seedlings began to sprout, continue to hoe the ground, and began to fertilize. One year, the mound of grafting nursery can be relaxed, and some of the thick soil layer can be stripped off, and the upper part of the terminal bud is still about 3.3 cm, so that the seedlings can be unearthed by themselves.

in late March (vernal equinox), buds appear when peony leaves are released, and the overwintering mulch on the upper part of peony that is more than 2 years old begins to be stripped, and the basal soil should not be greatly moved. When the soil buds grow 3 ~ 4 cm above the ground, 3 ~ 4-year-old peony takes the over-dense soil buds and carries out shaping and pruning. The seedlings of seed seedlings are unearthed, the ground is watered once, and some sesame or rapeseed cake fertilizer is chased.

in late March, topdressing was applied to 2-4 year-old peony in combination with hoeing, but topdressing was not required for 1-year-old peony, and quick-acting fertilizer was applied to 2-year-old grafting nursery.

April

The monthly average precipitation is 34.88 mm; The monthly average temperature is 14℃; 5 cm ground temperature is 14.7℃, and 15 cm ground temperature is 15.99℃.

Early April (Qingming): Buds enter the vigorous growth period, and the work of fixing branches and taking buds is continued.

Late April (Grain Rain): Peony blooms, with early flowering varieties opening 3-5 days in advance and late flowering varieties starting to bloom 3-5 days after Grain Rain. The whole flowering period is 1-15 days, and the single flowering period can reach 5-7 days. In sunny weather, artificial pollination is carried out.

in may

the monthly average precipitation is 44.56 mm; The monthly average temperature is 19.9℃; 5 cm ground temperature 21.3℃, 15 cm ground temperature 22℃.

Early May (long summer): After the flower withers, the plants are growing vigorously, and the flower buds are beginning to differentiate. The peony plot should be topdressed generally, and combined with topdressing, shallow ploughing or deep hoeing to loosen the soil once. The 23-year-old peony branches that are ready to be cut after autumn are cultivated at the base.

late may (xiaoman): when the weather is getting hotter, hoe the ground in time to conserve moisture, and in case of drought, ditch and irrigate it in time, especially for peony cutting and seed nursery. Water once every 7-1 days in drought. Leaf spot disease begins to occur, which can be controlled by spraying.

in June

the monthly average precipitation is 13.6 mm; The monthly average temperature is 25℃; 5 cm ground temperature 26℃, 15 cm ground temperature 26.5℃.

early June (awn seed): the temperature is getting higher and higher, so we should continue to loosen the soil and conserve moisture. More attention should be paid to drought watering in seedling raising and cutting peony. Since the middle of this month, peony has turned into a semi-dormant state in summer due to high temperature. The seeds have begun to grow, so you can chase some phosphorus-containing quick-acting fertilizers after rain or watering.

late June (summer solstice): continue to prevent diseases, insects, soil loosening and weeding. If there is more rain, shallow hoe should be used after the rain; Start the second pruning work, and cut off the "soil buds" and the extra buds sprouted from the old branches from the root and neck.

in July

the monthly average precipitation is 222.1 mm; The monthly average temperature is 26.9℃; 5 cm ground temperature 28℃, 15 cm ground temperature 28.5℃.

the first ten days of July (light summer): this period is hot and rainy, the weather is sultry, and there is a lot of rain. After the rain, shallow hoeing should be done in time to eliminate weeds, and the accumulated water in the ground should be discharged in time to prevent roots from rotting. At this time, the seed nursery is prepared.

Late July (summer heat): After the summer heat, seeds will be harvested. When the fruit horns of peony are crab yellow (the seeds are bright yellow-green), they can be harvested. Take off the peel together and put it in a cool underground room to complete the self-cracking after ripening.

in August

the monthly average precipitation is 153.5mm; The monthly average temperature is 25℃; 5 cm ground temperature is 26.7℃, and 15 cm ground temperature is 27.7℃.

early August (beginning of autumn): the seeds are harvested.

Late August (summer): The summer heat has passed, and the peony grows actively again. Leveling the nursery land, the seedlings can be planted after the summer heat.

in September

the monthly average precipitation is 44.2mm; The monthly average temperature is 2.5℃; 5 cm ground temperature is 2℃, and 15 cm ground temperature is 23.69℃.

in the first ten days of September (Bailu), the seed seedling raising work is completed, and the peony is grafted and cut. Every year peony hoes the ground for the last time, tidies up the land and prepares to plant peony separately.

late September (autumnal equinox): continue grafting and cutting peony, and start planting peony separately.

The average monthly precipitation in October

is 3.78mm; The monthly average temperature is 13.5℃; 5 cm ground temperature is 15.3℃, and 15 cm ground temperature is 17.2℃.

in the first ten days of October (cold dew): after grafting peony, we will continue to plant peony separately and start processing Paeonia suffruticosa.

Late October (first frost): Peony planting is finished, and the fallen leaves of peony are picked up. At the end of October, the soil will be sealed to prevent cold and winter.

November

The monthly average temperature is 6.4℃; The ground temperature is 7.3℃ for 5 cm and 1.6℃ for 15 cm.

in the first ten days of November (beginning of winter), the peony which is more than two years old will be fertilized.

late November (light snow): continue to seal the soil for wintering and apply fertilizer. Underground roots stop growing.

The monthly average temperature in December

is .7℃; 5 cm geothermal 2.2℃, 15 cm geothermal 3.2℃.

early December (heavy snow): water once before freezing if possible.

Late December (winter solstice): Use the slack time to accumulate fertilizer.

note: generally, hoeing is 8-1 times a year. After rain or watering, you must hoe, wet and shallow, and hoe frequently; Less rain, deep hoeing, soil conservation. In a word, peony land should be kept loose and free from weeds.
