Rose heat prevention campaign! It can be easily done with 3 steps, and the flowers will bloom continuously and fill the pot!

Summer vacation

Sunshade

1. Sunshade net

When caring for roses outdoors, if the plants are large and numerous, you need to pull up a shade net. Be careful not to provide full shading, just half shading will be enough. Of course, if you don’t find it troublesome, you can also use a parasol.

2. Bamboo mat or insulation board

When roses are kept against the wall, the wall absorbs a lot of heat and the heat will be directly transferred to the roses. At this time, you need to hang a bamboo mat or insulation board against the wall to provide shade and insulation.

Basin

Choose a ceramic pot that is two circles larger than the original rose pot, spread a layer of gravel on the bottom of the pot, and then place the rose pot into the large pot, being careful not to allow the two pots to touch directly.

You can also stuff soaked paper towels, sphagnum moss, shallow-rooted weeds, etc. between the two pots to achieve cooling, insulation, and moisturizing effects.

Raspberry

Covering the potting soil with tree bark or sun-tolerant plants with shallow roots can prevent the rose potting soil from drying out. Be careful not to cover more than half of the area, and leave the other side for ventilation and to observe the dryness and wetness conditions.

Combination potted plants

If the rose pot is large, you can use the combined potting method to provide shade and care, and place heat-resistant plants such as perilla and sunflowers around the rose to create shade for the rose.

Cooling

The most suitable growth temperature for roses is 18~25 degrees. It is not enough to just avoid the heat. Some cooling measures need to be taken at the same time so that they can grow well.

Ventilation and cooling

When growing roses on an indoor balcony, even if you open the windows for ventilation, the roses will still be stuffy. If you turn on a small fan and blow it next to the potted plants, you can increase air circulation and reduce the temperature. Be careful not to blow directly into the flower pot.

Water spray

When the temperature exceeds 33 degrees, the rose will be in a semi-dormant state. At this time, you should spray water once in the morning and evening every day, and spray the air and ground around the plant to cool it down.

Maintenance

illumination

Roses love light and need sufficient light to make the flowers large and colorful. During the peak growth period, it is necessary to ensure more than half a day of light every day. When entering the high temperature semi-dormant period, pay attention to shade and avoid exposure to the sun.

Watering

Roses cannot lack water during the entire growth process. If the temperature is too high, the plant's water evaporation and consumption will be very large. Spray water on the plant every morning and evening, and water it thoroughly every 2 to 3 days to ensure that the soil in the pot is moist.

Fertilization

During the flowering period, apply decomposed bean cake fertilizer, chicken manure fertilizer or compound fertilizer once every 10 days or so, apply thin fertilizers frequently, and reduce fertilization in hot weather.

Pest control

Pests

In summer, roses are easily infected by scale insects, aphids, red spiders, etc., which are mostly caused by high temperature and humidity, poor ventilation and poor light. Once discovered, the infected branches and leaves should be cut off immediately, the branches should be thinned out and ventilated, and at the same time, 10% imidacloprid wettable powder should be sprayed at 2000 times the concentration.

Diseases

Common diseases of roses include powdery mildew and leaf spot. First, cut off the diseased leaves and branches, and spray the diseased area with 500~1000 times diluted Guoguang Inna or carbendazim solution, once a week, about 2~3 times can be effectively treated.
