How to care for window-sill clivia in winter? A detailed guide to topdressing methods for edible fungi

Clivia can be grown in cellars, or on windowsills and balconies. Ordinary enthusiasts mostly grow clivia on windowsills or balconies. Everyone is concerned about how to care for them well during the cold winter.

My view is that if a greenhouse can grow clivia well, a windowsill or balcony can do so just as well. The key lies in creating good conditions suited to clivia growth.

The conditions for growing clivia are nothing more than water, fertilizer, temperature, light, humidity and temperature difference. For clivia grown on a windowsill or balcony, fertilizer, soil and temperature are the most important; the problem is controlling light, temperature and temperature difference well.

Light:

Clivia is a plant that prefers short, weak light and has low light requirements; generally four hours of direct sunlight, with scattered light the rest of the time, is enough.

Of course, all-day light in winter is ideal, but this can only vary with conditions. The light I am talking about here focuses on controlling artificial lighting. In winter, days are short and nights are long, and ordinary households turn on electric lights in the morning and evening, which lengthens the light exposure for clivia, violates its short-light characteristic, and is not conducive to clivia flowering and shooting up its scape. The solution is to shade it with black cloth at night so that the clivia sees no light.

Humidity:

The relative humidity of the environment in which clivia grows is about 80% during the day. If the humidity is too low, clivia leaves lose too much water, which affects the absorption of carbon dioxide and is not conducive to photosynthesis, inevitably leading to poor nutrition. This is not conducive to the vegetative growth and reproductive growth of clivia, and delays flowering and fruiting.

The solution is: just nail a square wooden frame above the windowsill, and hang plastic sheeting on the top and the other three sides of the wooden frame. Place a water container under the flowerpot; to control temperature, around noon when sunlight is abundant, the temperature inside the plastic tent rises and the relative humidity tends to drop, so you can appropriately spray water with a sprayer to raise the relative humidity of the environment.

Temperature difference:

Clivia, like other green plants, carries out photosynthesis during the day, taking in a large amount of nutrients, and decomposes those nutrients at night. The speed of decomposition is directly related to temperature: when the temperature is high, decomposition is fast, the plant accumulates less surplus, which hinders the plant's growth and development, is even less conducive to flowering and shooting up its scape, and easily causes the scape to be trapped. When growing flowers on a windowsill, most are in bedrooms; heating at night makes the temperature higher, while during the day the temperature can only rise through light, so the temperature is on the low side, leaving clivia in a constant-temperature state with little day-night temperature difference. The nutrients taken in during the day and those decomposed at night are almost equal, making it hard to sustain its survival, let alone healthy growth and flowering with the scape shooting up. With a plastic tent, strong daytime light raises the temperature quickly, heat is concentrated, and the temperature inside the plastic tent can reach 20-28°C, or even higher. At night, appropriately control the opening gap of the plastic sheeting to maintain a certain amount of air flow with the room, achieving the purpose of regulating the temperature inside the plastic tent. Keeping it controlled at 13-15°C is easy to accomplish.
