Before planting, clean the roots and leaves of spring sword with clean water, then trim the residual and rotten roots, and remove all the diseased leaves and dry leaves. Then soak the roots of the spring sword for a while with diluted potassium permanganate solution and dry them for a day before planting.

Water management

Spring Jian likes a more humid environment, but the flowers are afraid of waterlogging, so be careful not to water too much and keep the soil slightly moist, generally speaking, when the basin soil is slightly dry.

When watering, do not pour water directly on the branches and leaves, you can slowly pour through along the edge of the flowerpot, be careful not to accumulate water, otherwise it is easy to rot the roots.

Fertilizer management

Spring Jian likes fertilizer better, so it is necessary to spread a layer of base fertilizer at the bottom of the pot when planting. Potted spring swords that have applied base fertilizer should be careful not to apply fertilizer again this year, otherwise it is easy to burn the roots with overnutrition. The spring sword of the next year can be fertilized properly before flowering or after sprouting new buds, the amount of fertilizer should not be too heavy, it can be applied thinly, and the seedlings can add a little nitrogen fertilizer. It should be noted that it is not suitable to apply fertilizer when the temperature is too high or too low.

Light management

The control of light is an important aspect of the maintenance of spring sword, if the sunshine is too strong or too much, it will cause spring sword leaves to yellowing or even wither and fall off. If the sunshine is too little, it will slow down the growth of spring sword, affect the germination of flower buds, and reduce the amount of flowering. The right amount of sunlight will make the spring sword grow vigorously, sprout more buds and improve the quality of flowering.
