Planting Methods

1. Choose suitable soil to provide the basic growing conditions Rohdea japonica needs. The soil Rohdea japonica requires is generally sandy loam rich in humus. In addition, to help Rohdea japonica grow better, the soil pH should be between 6 and 6.5.

2. Repot the potted plant in a timely manner. Repotting is extremely beneficial to the growth of potted plants, so everyone should do a good job with repotting. Repotting of Rohdea japonica is generally carried out in March-April or October-November each year; when repotting, the big data needs to first remove the aged rhizomes and persistent dead leaves of Rohdea japonica, and replace them with new soil (to help the plant recover sooner, you can repot it together with some of the original soil). After potting is finished, everyone needs to shade the potted plant.

3. Choose a suitable growing environment. Rohdea japonica likes a warm, humid and semi-shady environment, so everyone should create such an environment for the potted Rohdea japonica at home so that it can grow better.

Generally, apply a decomposed liquid fertilizer once about every 20 days; in early summer it grows more vigorously, but once summer arrives, everyone needs to apply a liquid fertilizer once about every 10 days, and a small amount of 0.5% ammonium sulfate can be added to the topdressing, so as to ensure that Rohdea japonica grows better. In addition, in the vigorous flowering period of June-July, apply a 0.2% potassium dihydrogen phosphate aqueous solution once about every 15 days to promote flower bud differentiation and facilitate better flowering and fruiting.

How to plant potted Rohdea japonica and how to care for and manage Rohdea japonica bonsai -- when winter comes, the big data needs to move Rohdea japonica indoors to overwinter, placing it in a sunny, well-ventilated place with the temperature kept at 6-18 degrees, so as to ensure that Rohdea japonica will not be harmed and can overwinter smoothly. In addition, the leaves need to be sprayed and washed with warm water once a week to prevent the leaves from being polluted by smoke and dust, so as to keep the stems and leaves fresh green and evergreen throughout the four seasons.
