How to repot the flowerpot when the roots are full?
When is the best time to replace soil with flowers?
The flowers we raise are usually potted. Because the soil used in flower pots is limited, and the soil does not contain many nutrients. As time goes by, the plant gradually grows and its root system fills the pot. Moreover, the soil is compacted, making it difficult to water thoroughly. Once watered, it is difficult to penetrate quickly, and fertilizers are not easily absorbed. Therefore, potted flowers should be repotted in time to prevent them from affecting the normal growth of the plants.
Repotting with fresh soil can provide new nutrients to plants and improve the growing environment. Let it absorb sufficient nutrients and maintain vigorous growth. This is the main purpose of changing potted flowers into new pots and soil.
Generally, potted plants can be repotted with soil once every one to two years. The best time to change soil is in spring or autumn, preferably in March or April. At this time, the plant metabolism is slow and new roots have not yet sprouted. When changing pots and soil, the roots of the plants are not easily injured, which is best for plant growth. If the repotting time is too early, the plant will be susceptible to frost damage. If the repotting time is too late, the temperature will gradually increase and new roots will begin to sprout. Repotting the plant will easily cause injury to the plant. In autumn, when the temperature is just right, you can also repot potted plants and change the soil.
However, if during the maintenance process, the soil becomes compacted and there is white powdery substance on the surface, or if the plant’s root system is damaged and rotten during maintenance, the potted plant should be repotted and soiled in time. Just be careful not to damage the roots too much and nurse the seedlings carefully.
When replacing potting soil in order to allow plants to grow normally, it is best to use a mixture of multiple soils instead of a single garden soil. Nutrient-rich leaf rot soil and peat soil can be mixed with some granular soil. For example, large particles of river sand, cinders, perlite, volcanic rocks, etc. have large gaps for water permeability, and some organic fertilizers or retting farmyard manure or slow-release fertilizers can be added.
Make sure the soil is loose, breathable and nutritious. And most potted flowers like slightly acidic soil, so if you have pine needle soil, you can mix it with 10% pine needle soil.
When changing the potting soil, control the water for two days and wait until the potting soil is almost dry before moving the pot. This will facilitate operation and reduce root damage. When repotting, 1/3 of the core soil can be retained to protect the main root from being affected. Gently rake the old soil to expose the new roots, then plant in loose, breathable soil.
If there are rotten roots or excessively long roots, they can be pruned appropriately. After potting, pour in carbendazim or mancozeb to disinfect and prevent root rot. After changing the pot, pay attention to slow down the seedlings and spray moisturizing every day. When the new shoots grow significantly, they can gradually receive light.
