The two essentials of raising rose in summer are still in bloom.

The summer temperature is high, the evaporation is fast, the transpiration of the rose is also strong, and the water demand is more, so for the rose, it needs special care in order to get through smoothly. So, if you want to blossom in the summer rose, there are two essentials to know.

The first key point: watering

The purpose of watering in summer is not only to provide water for the growth of rose plants, but also to regulate temperature and humidity. As for the amount of water watered in summer, flower friends should depend on the type of rose, the size of the plant, and the actual dry and wet condition of the pot soil.

General growth period rose, more water content, transpiration intensity, watering should be more; if it is dormant rose, watering can be appropriate less. Under normal circumstances, the rose should be watered once or twice a day, never half of the water, otherwise the rose root system can not absorb enough water and make the leaves curl up and yellowing, the whole plant will die after a long time.

It is best to use soft water for watering in summer. if you use tap water, you need to dry the water for 1 day before watering it when the water temperature is close to the soil temperature. Watering time is appropriate in the morning and evening, do not pour cold water at noon. If the root system of rose is irrigated with cold water at noon in hot summer and cannot be absorbed immediately, but the transpiration of leaf surface is strengthened under high temperature, the phenomenon of so-called "physiological drought" appears, which makes the leaves scorch and, in serious cases, cause the death of the whole plant.

If in the early stage of rose budding and flowering, cold water is watered at noon in summer, it is also easy to cause buds and flowers to fall, which must be paid attention to. It should also be pointed out that due to the high soil temperature in summer, water must be watered in time after showers to eliminate the damp heat in the basin soil and reduce the basin soil temperature. in addition, if there is stagnant water in the basin after a rainstorm, it should be poured out immediately, or use a bamboo stick to pierce several small holes in the basin soil (do not hurt the root), so that the water flows out from the drainage hole at the bottom of the basin, otherwise it is easy to cause rotten roots.

The second key point: fertilization

When fertilizing rose in summer, we should grasp the principle of "applying thin fertilizer frequently". Excessive concentration of fertilizer is easy to cause rotten roots. Generally, rose varieties with vigorous growth should be treated with special organic nutrient solution for rarefied rose about every 10-15 days. Fertilization should be carried out when the basin soil is dry in sunny days, because wet root fertilization is easy to rot roots.

Fertilization time should be in the evening, because the soil temperature is high in summer, fertilization at noon is easy to hurt roots. One permeable water should be irrigated the following day. Fertilizer should also be careful not to splash fat and water on the leaves, so as not to burn the leaves.
