The kiwi plants also like a soiled land with a pH of 5.5 to 6.5. The soil must also be fertile in terms of organic matter and able to drain well in order to prevent root rot. Watering is required on a regular basis particularly when the flowers are blooming and the fruits growing, however not when it is waterlogged. Around the base, applying mulch can help preserve the moisture, control the temperature and reduce the growth of the weed. Once or twice per week deep watering is usually preferable to the frequent and shallow watering to promote healthy root development.
