How to care for water-and-land bonsai? A full analysis of practical tips
Watering: Water-and-land bonsai are planted in very shallow pots, so special attention must be paid to replenishing water in time. To prevent the potting soil from being washed away when watering, it is best to use a fine-nozzle watering can. When the climate is dry, a sprayer can be used to mist the pot surface, the trees and the rocks to keep the moss growing well.
Fertilizing: The soil in water-and-land bonsai is relatively little and nutrients are limited, so attention should be paid to fertilizing to keep the trees growing vigorously. Fertilizing is mostly done by spraying diluted organic fertilizer water onto the soil surface. Granular organic compound fertilizer can also be buried in the potting soil.
Repotting: The trees in water-and-land bonsai are generally repotted once every 3 to 5 years, mostly in spring and autumn. When repotting, first remove the decorative stones and accessories (be sure to note their positions), carefully pull out the tree together with its soil, use a bamboo stick to remove about one-half of the old soil, cut off dead roots and some old roots, replace with fresh soil, replant it in the pot in its original position, then put the accessories back in place and lay down the moss.
Placement and protection: Ordinarily, it is best to place it in a well-ventilated spot with good light. In summer, protect it from prolonged fierce sun, and in winter move it indoors to a spot with ample light; it must not be allowed to freeze. During the plant's growing season, take care not to keep it indoors for several days in a row, so as not to affect its growth.
The methods for preventing and controlling pests and diseases in water-and-land bonsai are the same as those for ordinary tree bonsai.
