It's time to popularize science-how can succulent plants make red edges?

Picture and text: this girl is a little sweet.

Whether succulent plants can grow red edges has something to do with the varieties of succulent plants. Some Sedum sedum can not grow red edges, but most of them have colorful leaves, from dark red, brown, blue, purple to even black. This is because plants are affected by the environment to produce different pigments, such as "β-anthocyanin" and "anthocyanin".

The cultivation of red edges has something to do with the following two important factors:

1. Light

Usually maintain succulent, the light must be sufficient, these pigments can be produced with photosynthesis, but sometimes some pigments can only be irradiated by strong light for a long time, especially the light source containing blue and ultraviolet rays to irradiate the plant. to force it to produce this kind of pigment. If the strong light is exposed for too long, the succulent plants will "change color" and naturally grow red edges. Therefore, in fact, the most important condition for Sedum to grow red edges is that the light must be adequate. However, some areas are affected by the objective living environment, and this condition is sometimes impossible to obtain.

two。 Use artificial ultraviolet rays

I believe that many meat lovers will worry about the lack of light at home, which will eventually lead to the death of succulent people, especially crassulaceae plants, which have a great demand for light. Therefore, if the lighting conditions in the home are not too good, it is indeed difficult to produce colorful leaf effect and red edge effect. If the lighting condition in the home is not too good, the artificial ultraviolet light source can be used to supplement the light, but the effect is not as good as that of the sun. even the artificial simulated ultraviolet radiation lamp can not completely replace the full-spectrum ultraviolet ray of sunlight, and this practice consumes a lot of power, and the regular plant supplementary lights and growth lights on the market are very expensive. The effect of many cheap imitation products purchased online is greatly discounted or many of them do not help.

Or the sun is better, save money, save effort and effort, although the use of artificial ultraviolet light source to supplement light, but still can not completely replace the sun. The problem of facing the balcony itself cannot be solved unless you move. So if you have a south-facing balcony, balcony or a flower friend with a yard at home, you will be one step closer to raising them. If you want succulent plants to be plated with red edges, the main thing is to have plenty of light.

How to choose the supplementary light?

There are a lot of supplementary lights for plants on the market. You can choose plant supplementary lights / growth lights that contain red light, blue light or a bit more complete spectrum. If you want to warm up and replenish the light at the same time in winter, you can choose UVA and UVB radiation lamps for reptiles, but the irradiation distance is not too close, because another important role of them is heating, the surface temperature of the lamp tube is very high, close irradiation will burn plants. In addition, incandescent lamp does not have much effect, it mainly emits yellow and white light and a lot of infrared light. Although very cheap and easy to get, but the electro-optic conversion efficiency is very low, not suitable for plants to supplement light, plants exposed to this light for a long time will become slender and weak. Therefore, plants such as crassulaceae, which are in great demand for sunlight, are certainly not suitable to be maintained in an indoor incandescent environment, and even if they do not die, they will certainly not be in good condition. Therefore, many people worry that Jingtian cannot be raised without sunshine. This is indeed the case. Jingtian has a close relationship with the sun.

Direct sunlight is the best (outdoor, balcony, south-facing balcony).

In the place where there is bright scattered light (not the south balcony near the window), in fact, do not worry, at most there is no bright color pigment effect, just green.

However, if you raise it in a medium-light environment (in the bright part of the room), it is very likely to grow a "water snake waist".

If you stay in a low-light environment for a long time (indoor away from the light), you are sure to die.

The above environments are actually a ladder state of Sedum plants. To choose a different environment for it is to choose what kind of state it wants to present to you. The red edge of succulent plants not only has something to do with the light, but also has a lot to do with the temperature difference, so don't blindly want the red edge, and let the succulent plants take a sauna on a hot day.

In addition, succulent plants such as the 12-volume genus require much less light than sedum.

Can not need all-day direct sunlight, but more suitable for indoor environment with bright scattered light to maintain. This is the difference in habits between different families and genera. "succulent plants" contain countless different families and genera, all of which have different habits and different needs, and cannot be applied to mathematical formulas.

If you really do not have good sunshine and hardware conditions, you might as well try to raise more shade-tolerant plants, such as 12-volume genera, some apricot families and some succulent plants of Liliaceae.
