Cultivation and maintenance of potted peony
Peony is known as the "king of flowers". Potted planting can not only decorate the room but also experience the fun of gardening. Mastering scientific cultivation techniques, even the balcony party can make the peonies bloom year after year. This article systematically sorts out the key points for the full-cycle management of potted peonies to help you create your own peony garden. Detailed explanation of potted peony cultivation techniques: Scientific soil matching and standardized planting Select clay pots with particulate matrix (perlite: leus soil: river sand =3:5:2). Before planting, soak the roots with 50% carbendazim 800 times solution for 30 minutes. Keep the main root 20cm long, cut the sick and weak roots obliquely, and pay attention to keeping the root mass intact. Lay 5cm-thick broken tiles on the bottom of the basin as a drainage layer. When planting, let the root system stretch in an umbrella-shaped shape, and cover it with soil to 2 cm above the junction of the roots and roots. The intelligent water control system maintains the substrate humidity of 40%-60% in spring and autumn (it will disperse when you hold it in a ball and let go of it). In summer, it sprays it in the morning and evening to increase humidity, and in winter, it controls the water until the substrate moisture content is 15%. Newly planted plants are replenished with water by dipping pot method, and mature plants are slowly watered along the edge of the pot. Special reminder: 20% of water supply needs to be increased during the flower bud expansion period. Nutrient supply plan In September, bone meal + rapeseed cake (1:3) was applied to Hefei, with 50g per pot buried in topsoil. Spray 0.2% potassium dihydrogen phosphate before flowering, and supplement 200g of decomposed sheep manure after flowering. Remember to ban nitrogen fertilizer during the growth period to avoid excessive branches and leaves affecting flower bud differentiation. Light and temperature control strategy The core points of potted peony maintenance Peony requires 1800-2500Lux light duration, full sunshine in spring, and 50% shade from 10:00-15:00 in summer. Maintain low temperature dormancy of 5-10℃ in winter, and the temperature difference between day and night during the flower bud differentiation period needs to reach more than 8℃. You can rotate the flowerpot so that the plants receive light evenly. Precise water management adopts the "three-look" watering method: look at the leaves (young leaves are slightly wilted), look at the soil (the surface layer is 3cm dry), and look at the weather (continuous sunny days). A rainproof canopy will be erected during the plum season, and sprayed in the morning and evening to cool down during the high temperature season. During the winter hibernation period, water should be replenished once a month, and the water temperature should be consistent with room temperature. Special season maintenance focuses on preventing and controlling red spiders from July to August. Yellow sticky insect boards can be hung with matrine spray. Cut off residual flowers in time after flowering, and retain 2-3 leaves to promote the germination of new buds. The pots are changed in autumn every two years, and 1/3 of the old soil is removed to replenish new substrate.
Through systematic cultivation management and precise maintenance, potted peonies can be formed in 3 years and bloomed in 5 years. Remember to thin buds properly before flowering and retain 1-2 buds at the top of each branch, which can increase the diameter of the flower by 30%. As long as these key technologies are mastered, peonies can also show their prosperity in a square inch potted plant.
