How to Repot Coin Grass
Coin grass, with its round and cute leaf shape, has become a favorite indoor green plant for many plant enthusiasts. Repotting, as an important part of its propagation and care, not only allows the plant to gain more growth space but also enables the cultivation of new seedlings through division. This article will systematically explain the entire process of repotting coin grass from the best timing to operational details.
Key Points of Repotting Coin Grass
Analysis of the Best Season for Repotting
In spring and autumn (March-April / September-October) when the daily average temperature is between 18-25°C, coin grass is in an active growth period. Repotting at this time allows the roots to quickly adapt to the new environment. High temperatures in summer can cause water loss and wilting, while low temperatures in winter may delay root development, making both seasons unsuitable for repotting.
Preparations Before Repotting
Stop fertilizing and control watering 3 days in advance to keep the potting soil slightly moist. Prepare sterilized gardening shears, breathable ceramic pots, and potting mix materials. For hydroponics, prepare a transparent container and ceramic stones.

Techniques for Dividing and Repotting
Hydroponic plants can directly select 5-8 rooted seedlings, gently rinsing the roots with running water. For soil-grown plants, tap the pot walls to remove the entire plant, then soak in water for 30 minutes to soften the soil before dividing along the natural tillering points, retaining roots that are more than 3 cm long.
Matrix Formulation
It is recommended to use a mixed matrix of decomposed leaf soil: garden soil: river sand in a ratio of 5:2:3, with the addition of 10% earthworm manure to enhance fertility. For hydroponics, a "semi-hydroponic" mode is suggested: a bottom layer of 3 cm of ceramic stones + a middle layer of peat soil + a top layer of 1 cm of coarse sand, which retains water and allows for breathability.
Planting and Care Tips
For soil culture, fill the soil to 2/3 of the pot height, cover the plant with the matrix and gently press, then water thoroughly and place in a scattered light area. For hydroponics, change the water weekly and add 3 drops of nutrient solution, with an additional application of water-soluble fertilizer every month after new leaves have unfolded, maintaining a light intensity of about 2000lx.
Post-Repotting Management Tips
Avoid direct sunlight for the first two weeks and maintain an air humidity of over 60%. Trim yellow leaves promptly and transfer to routine care after new buds have grown 2 pairs of true leaves. For soil culture, apply a diluted 2000x leafy plant special fertilizer every 15 days, and for hydroponics, clean the container monthly to prevent algae growth.
By mastering the timing of repotting and the correct operation methods, the survival rate of coin grass can reach over 95%. After 2-3 months of repotting, a full plant shape can be formed, and proper pruning can cultivate an ornamental potted plant with distinct layers. It is recommended to repot every spring to maintain plant vitality and harvest more new coin grass seedlings.
