Can roses be exposed to rain?

The benefits of rain

In fact, there are many benefits for roses if they are exposed to rain.

When it rains, you can water the roses so that the water in the pot reaches a saturated state, which is not easy to achieve in daily watering.

Rainwater is generally slightly acidic because carbon dioxide in the air dissolves into carbonic acid in rainwater. It just so happens that roses prefer a slightly acidic growing environment, and being exposed to rain can meet this need of roses.

Secondly, elements such as oxygen and nitrogen contained in the air will be absorbed by roses with rainfall. In particular, nitrogen cannot be directly absorbed by roses. Through rainfall, it can be converted into nitrogen compounds to supplement nutrients for roses. Before it rains, the air will contain some condensation nucleus substances. These substances are rich in trace elements and play an important role in the growth of roses.

Another point is that by letting the rain fall, you can clean the rose plants, absorb the dust on the surface, and make their pores unblocked, which helps the plants breathe and grow better. It can also make the leaves fresher and more beautiful.

Precautions

Although there are so many benefits to letting roses be exposed to the rain, it does not mean that you can just let them be exposed to the rain. There are many things to pay attention to.

First of all, the rose flowers that have just been potted should not be exposed to rain, because the root system has not yet stabilized. They need to be watered when the soil is dry and wet to promote the growth of new roots.

Secondly, in some heavy industrial areas, the air pollution is very serious, and most of the rain that falls is acid rain, which is not conducive to the growth of roses.

Also, it is best to get wet in the rain every few days. It is best not to get wet in the rain when it rains continuously to avoid water accumulation. It is best not to get wet during heavy rain to avoid washing the plants out.

It is best to check the roses after the rain, and it is best to spray some fungicides to prevent infection by pests and diseases.
