One. tree peony plants management
transportation will damage some Chinese tree peony seedlings. Before planting, you should prune the seedlings. Depending on the degree of damage, the roots and branches should be half-cut or full-cut. After transplanting, the main branches can have sufficient nutrition supply, repair the cut of broken branches.
Two.Tree peony planting
We divide planting time into spring and autumn. For spring, the best time is from mid-March to April 20. For autumn, the best time is from late July to early November. Warmer temperatures can help new roots grow.
Soil preparation: When planting peonies, avoid wet soil. Too much moisture can harm the roots. It is best to plant in high, dry, well-drained, deep, and loose soil.
Neutral or slightly alkaline loam or sandy loam works well. This helps the roots grow deep and strong. When they bloom, the flowers will be big and bright.
PLANTING: Plant 30 cm deeper than the root of the original plant. At the bottom of the pit, add some decomposed organic fertilizer and chemical fertilizer to the soil. Mix them well so the new roots can absorb the fertilizer quickly.
When planting, the root system should be spread out evenly in the hole. It should not be curled together. Fill the hole with good soil, covering the roots first. Then, gently shake the seedlings up.
First, the root system should be fully integrated with the soil. Second, the planting depth (the planting depth should be lower than the original root neck about 3 centimeters above the ground) should be determined.
First, step on the soil to make it solid. Then, fill the soil around the plant. After planting, water it right away. This helps remove air from the soil. It also protects the roots from cold in winter.
Three.Post-planting management
Winter Management:
Tree Peony is usually planted in the fall. The first winter needs special care. Here are the main tips:
(1) timely watering the overwintering water and reasonable fertilization to ensure the nutrition and water required for the roots in winter. The best time to fertilize is before the soil freezes in autumn and winter.
You can use more fertilizer then. This helps protect the rockii tree peony during winter. You can use whole fertilizer or compound fertilizer that is available in stores.
(2) cut off dead, old and useless twigs in winter.
Winter protection can be omitted for Paeonia rockii due to its strong cold resistance, which generally ensures safe winters.
To help plants grow next year in very cold areas, you can prepare them before winter. First, bunch the branches together. Then, in mid-October, bury the plants in soil about one-third to one-half deep. After that, cover the whole plant with soil twice during the first ten days of November. Make sure to add more than 10 cm of soil above the top branches.
Spring Management
(1) water
In the spring, when the temperature goes above freezing, slowly remove the cold-proof material. This helps the branches and leaves to grow.
At this time, the surface is thawing. Young branches grow quickly. If the ground is dry and water is low, new buds may wither. Old branches can die.
It is important to water them on time. After each watering, loosen the soil around the tree peony seedlings.
(2) fertilization
tree Peony loves fertilizer. Fertilization is key in plant care. Fertilizing once in spring is best.
This usually happens from late March to early April. During this time, the buds grow quickly. They need many nutrients to help them grow. Root damage can affect how plants absorb water and fertilizer. To help, use a mixture of 5% DODDO and 3% urea. Spray this mixture on the leaves every 7 to 10 days after the leaves have spread.
Spring pruning
In spring, when the new buds appear on the ground, there is a choice of shaving, so as to avoid too many branches in the future, affecting the tree type and nutrients. When the new bud grows to about 10 cm, you can select a few of them to keep as the main branch (commonly known as fixed stock) and remove the rest.
In order to make tree peony flower big and beautiful, often combine pruning for thinning bud, wipe bud work, so that each branch to retain a bud, the remaining bud removed, and the old branch issued by all the adventitious buds removed, in order to concentrate nutrients, flowering huge.
In addition, the first year to ensure the normal growth of tree peony plants and restore healthy, need to take off bud, usually a bud. If the tree peony is planted in spring, the first year should be removed all the buds, so that the full supply of nutrients to the tree growth.
Summer Management
Summer is the main time for chinese Peony growth. During this season, the plant gathers nutrients and forms flower buds. However, it is also a time when diseases, insects, weeds, drought, and floods can cause damage.
Therefore, strengthening the scientific management of paeonia rockii in summer is beneficial to the healthy growth and good development of rockii tree peony. The main points are as follows:
(1) irrigation and drainage
In summer, the precipitation is large and relatively concentrated, so drainage is one of the important measures for the tree peony pipe, and some areas often appear drought, and timely irrigation. The concrete measure of drainage is to repair the field drainage ditch in time.
Low-lying areas, the tree Peony Garden around the flood cofferdam to prevent heavy rain when the inflow of external ground. Large planting areas should be equipped with drainage pumps for emergency use.
It can also accelerate the water loss of plough layer by deep tillage or increasing the times of tillage. Poor drainage is one of the important reasons for tree peony “degeneration” in rainy areas.
(2) scientific fertilization
After anthesis, apply fertilizer once in time, mainly inorganic fertilizer. To use this method, apply urea and diamine to the ground. Each plant needs 0.05-0.1 kg, depending on the seedling size. The pit should be near the top of the seedling’s root system. Then, add the right amount of water.
(3) pest control
Summer high temperature and high humidity, diseases and pests more serious, mainly leaf diseases and food pests. To prevent and control diseases and insect pests, we should combine prevention with control. This helps the leaves stay healthy and improves the root system’s activity.
One of the concrete measures is to spray leaf protective agent, about two weeks after flowering, leaf spraying 0.5% of lime equivalent bordeaux liquid, to prevent the invasion of bacteria leaves. General effect can maintain about two weeks, continuous spray 2-3 times. The dosage is about 100-150 kilograms per mu.
The other is to spray fungicide. From July to August, tobrazine, Carbendazim, chlorothalonil, Triadimefon and other fungicides spray 3-4 times, generally 7-10 days a spray.
The third is to kill insects. Can Be combined with spraying fungicides, in the liquid pesticides such as pyrethroid insecticides, Omethoate, and so on, to prevent and control eating pests.
(4) weeding by ploughing
Summer is the peak season for weeds. Weeds compete with peonies for water and fertilizer. They also overcrowd the field, reducing air flow and light. This can lead to diseases and insect damage. Weeds weaken photosynthesis and affect how flower buds develop.
Intertillage can not only weed, but also keep moisture. The general summer should be ploughed 5-6 times. In some areas, people spread hay between plant rows. This helps control weed growth and keeps the soil moist and cool.
Cut the bud: After the flower falls off, remove the leftover flower quickly. This helps the roots grow and become strong again.
Fall Management
Autumn is an important period for root growth of rockii tree peony. Timely watering, fertilizing and reasonable pruning can ensure the rapid recovery of the next year’s plant to meet the basic needs of plant growth and development throughout the year. In late autumn, before plants go dormant, use a “root fertilizer.” Apply “frozen water” and compost after the plants are fully mature. You can also use cake fertilizer or other compound fertilizers. Make sure to use enough fertilizer.
In addition, autumn is the period when the diseases and insect pests begin to multiply. We should cut off the diseased and dead branches in time, clean up the weeds and dry branches in the park, so that there is no place for the diseaseweeds and dry branches in the park, so that there is no place for the disease and insect.
