Which plants need to be repotted in spring
A comprehensive analysis of the plants that need to be repotted in spring and a review of the knowledge related to the four kinds of flowers that need to be repotted in spring to grow vigorously. Next, let's introduce them.
Different types of flowers and plants have different growth habits. Some flowers have weak root systems and slow growth, and do not need to be repotted for several years after planting; while some flowers have vigorous vitality and rapid root growth, and over time the roots may fill the entire pot, making it look like the soil is "eaten" away. If repotting is not done in time, it is easy to have issues such as yellowing leaves, cessation of growth, and no flowering.
The following four flowers must be repotted every year. Take advantage of the warm spring weather and get started!
Chlorophytum comosum (Spider Plant)
Chlorophytum comosum is an extremely common potted plant in daily life, with many flower enthusiasts growing it at home. There are many varieties of hanging baskets on the market, such as variegated Chlorophytum comosum, silver-edged Chlorophytum comosum, colored leaf Chlorophytum comosum, and golden hearted Chlorophytum comosum. All types of Chlorophytum comosum have very strong root systems. Their roots are short and thick, resembling small white radishes. They grow very fast and can fill the entire pot in about a year, absorbing all the nutrients in the soil. If the pot is not changed the following year and the soil is not supplemented with new nutrients, it will severely interfere with the subsequent growth of Chlorophytum comosum.
Repotting Precautions
Repotting Chlorophytum comosum is usually done in spring or autumn. When the temperature is around 15 degrees Celsius, it is the best time to repot. For plants that are three years or older, prepare a pair of scissors when repotting and trim 1/5 to 1/4 of the old roots. Old roots have weak vitality and take up unnecessary space in the pot. Trimming old roots can promote the growth of new roots and enhance the plant's growth.
Clivia Miniata (Kaffir Lily)
The roots of Clivia Miniata look like thick chopsticks and are considered fleshy roots. This type of root is delicate and has high soil requirements. The soil in potted Clivia Miniata older than two years significantly decreases in aeration and drainage. Without regular soil replacement, waterlogging can occur inside the pot after watering, leading to root rot and leaf yellowing. Therefore, young Clivia Miniata plants need to be repotted every year, while older plants should be repotted every 1 to 2 years.

Repotting Precautions
When repotting Clivia Miniata, pay attention to the temperature and ensure it is between 15 to 25 degrees Celsius before proceeding. Early spring can experience sudden drops in temperature due to spring cold snaps, and late spring, approaching summer, may have elevated temperatures. Therefore, it is not suitable to repot Clivia Miniata in early or late spring. Experienced gardeners usually choose to repot in the mid-spring, around the end of February to March.
When repotting Clivia Miniata, observe the roots and cut off any rotten, hollow, or insect-damaged ones.
Crinum asiaticum (Red Spider Lily)
Crinum asiaticum is a perennial herbaceous plant of the Amaryllidaceae family, with trumpet-shaped flowers, large blooms, and bright colors, making it highly ornamental. Crinum asiaticum has a powerful bulb. Usually, the plant absorbs nutrients from the soil and stores them in the bulb, and in winter, the pot is moved to a warm room where the plant uses the nutrients stored in the bulb to bloom. To care for Crinum asiaticum, it is necessary to replace the old soil with new soil every year to provide a good growing environment for the bulb.
Repotting Precautions
The optimal planting temperature for Crinum asiaticum bulbs is between 20 to 25 degrees Celsius. There are two seasons in a year most suitable for planting: one is around September in autumn, and the other is April to May in spring.
When planting Crinum asiaticum, it is essential to use loose, well-draining, slightly acidic soil. If the soil fertility is insufficient, the bulb will grow slowly. Lazy gardeners can purchase ready-made nutrient-rich soil from the market. Of course, you can also mix your own soil. Here is a suggested soil mixture: 4 parts of decomposed leaf soil, 2 parts of coarse river sand, and 2 parts of garden soil, with a small amount of well-rotted organic fertilizer as a base fertilizer. Mix all materials evenly and use.
Epipremnum aureum (Golden Pothos)
