Do you use red red in a deep basin or a shallow basin?
As a representative of the bulbous plant of the Amarylliaceae family, Zhu Dinghong is deeply loved by gardening enthusiasts for its tall and straight flower arrows and colorful colors. However, many flower lovers often overlook an important detail during the maintenance process-the selection of flower pots. This article will provide an in-depth analysis of flowerpot selection strategies for different growth stages of Zhu Dinghong, and guide you to master the scientific matching rules of deep pots and shallow pots. 1. Core principles for selecting pots for Zhu Dinghong 1. Key points for shallow pot maintenance during the seedling period It is recommended to use a shallow pot with a height of 15-20cm for initial planting of seeds. Its advantages are reflected in three aspects: first, the shallow soil can accelerate water evaporation and prevent new roots from rotting; secondly, limited space can stimulate the lateral development of the root system and cultivate Strong root groups; finally, the shallow pot makes it easier to control the substrate humidity, which is especially suitable for young plants with a diameter of less than 5 cm. It is recommended to use a vegetarian pottery pot with a diameter 3-5cm larger than the seed ball, and gradually increase the container size when changing the pot every spring. 2. Standard selection for deep pots during the adult plant period. High-waisted pots with a depth of ≥25cm should be selected for mature Zhu Dinghong. Such containers can accommodate enough nutrient soil to meet the needs of bulb expansion. An ideal deep basin needs to have: ① 1/3 of the basin bottom is filled with a ceramite drainage layer; ② The number of ventilation holes in the basin wall is>8; ③ The basin diameter is 2-2.5 times that of the bulb. Pay special attention to avoid using containers with a depth of more than 40cm. Too deep may lead to long-term moisture in the lower half of the soil and induce root rot. 2. Advanced skills for selecting pots with red tints 1. Comparative analysis of material properties Through experimental data, common materials are compared: coarse pottery pots have the best air permeability (porosity 32%), red pottery pots are second (28%), and plastic pots are the lowest (3%). Although purple sand pots are beautiful, they are expensive, and glazed ceramic pots are completely unsuitable. It is recommended to use a tile basin with foot pads, which can not only raise the drainage hole, but also adjust the humidity through the pores in the basin wall. 2. The special shape pot adaptation plan is for special shaped flower pots such as chunky and high-footed flower pots. It is recommended to follow the principle of "2:1 height ratio": the total height of the pot should be twice the height of the bulb, and the pot mouth should be kept to 1 times the height of the bulb. For example, to plant 8cm high bulbs, it is best to choose a container with a total height of 16cm and an upper space of 8cm. 3. The whole process of pot replacement and maintenance of Zhu Ding Red. When the pot replacement operation is carried out from March to April every year, containers that are gradually larger are selected according to the size of the bulb. The key steps include: ① After pruning roots, soak in carbendazim solution for 20 minutes; ② Disinfect the new pot with boiling water; ③ Prepare the substrate according to the ratio of legus soil: river sand: vermiculite =5:3:2; ④ Keep 1/3 of the planting depth exposed to the soil surface. After changing the pot, place it in a cool place to slow down the seedlings for 2 weeks, during which time water is strictly controlled.
Through the combination of scientific pot selection and regular pot change, the red corms can maintain a growth rate of 1.5- 2 cm per year. Remember the maintenance formula of "small seedlings promote rooting in shallow pots, and grow plants into deep pots to cultivate bulbs". Combined with the breathable tile pot material, your vermilion red will definitely bloom with gorgeous flowers every year.
