Key points of maintenance

1. Lighting management

Cold spray is a kind of indoor flower with beautiful leaf color, which is very shade-resistant, but prefers sufficient light and should avoid direct light. Flowerpots are placed in the north window in summer and in the south window in winter. If the light is too dark, the color of the leaves will fade; if the sun is too strong, the leaves will be burned.

Second, temperature management

Cold hydration is more cold-resistant, it will not freeze at room temperature no less than 6 ℃ in winter, and it will begin to grow above 14 ℃ in winter.

III. Fertilizer and water management

Master the principle of wetting management, keep the basin soil dry and uncracked, moist but not wet. In summer, often spray water on the leaves to keep them clean and shiny. Spray less water on the leaves in winter, otherwise the leaves will appear black spots, or even black and rotten. Watering 28% or 37% liquid nitrogen fertilizer at a time in about two weeks during the growing period makes the plant strong. After autumn, increase the application of phosphorus and potassium fertilizer to strengthen the stem and prevent lodging.

IV. Methods of reproduction

Cold water spray propagation multi-use cutting methods, spring and autumn can be carried out. When the number of families is less, the top of the stem is used as cuttings in May, and the medium is river sand or vermiculite. Under the suitable temperature (20 ℃ to 25 ℃), rooting takes place in about 10 days. When the new bud lengthens from 3 cm to 5 cm, put it on the basin with sandy soil. Pour enough water to fix the root and transfer to normal management.

5. Soil

In order to enhance the pot ornamental effect of cold splash, the growing period should be pruned regularly to promote its branching and maintain full plant shape. If you want to dwarf the cold splash plant, you can prune it properly or pick the heart for 2-3 times. Be careful not to prune too much, otherwise it will easily lead to many and small cold splash leaves, affecting the aesthetics.

VII. Disease and pest control

Change the basin once a year. When the shape of the old plant is scattered and the ornamental value decreases, the regeneration of seedlings by cutting can improve the ornamental value. At the same time, it can also reduce the harm of diseases and insect pests. In the case of poor ventilation, it is vulnerable to aphids. When the basin soil is muddy for a long time, the roots often rot, so we should pay attention to reasonable control of soil and water.
