Summer vacation

Shade

1. Shading net

For outdoor maintenance of rose, when the plant is large and large, you need to pull a shading net. Be careful not to block out all light, just half light. Of course, you can also use a solar umbrella if you feel troublesome

2. Bamboo mat or heat insulation board

When the rose is cured against the wall, because the wall absorbs much heat, the heat will be directly transmitted to the rose. At this time, a bamboo mat or heat insulation board needs to be hung against the wall for shading and heat insulation

Set Basin

Choose a pottery basin two circles larger than the original flower pot of rose, lay a layer of broken stones on the bottom of the basin, and then put the rose basin into the large basin. Pay attention not to contact the two pots directly

Paper towels, water moss and shallow root weeds soaked in water can also be stuffed between the two pots to play the role of cooling, heat insulation and moisturizing

Covered Basin

Cover the pot soil with bark or sun resistant plants with shallow roots to prevent the rose pot soil from being dried through. Pay attention to not more than half of the coverage area, and keep ventilation on the other side and observe the dry and wet conditions

Combined potting

If the rose pot is large, the method of combined potting can be used for shading and maintenance, and heat-resistant plants such as perilla and sunflower can be placed around the rose to create shade for the rose

Cool down

The most suitable growth temperature of Chinese rose is 18 ~ 25 degrees. Summer vacation alone is not enough. We need to take some cooling measures at the same time to grow well

Ventilation and cooling

When raising roses on the indoor balcony, even if the window is opened for ventilation, the roses will still be muggy. If you turn on a small fan and blow next to the potted plants, you can well increase the air circulation and reduce the temperature. Do not blow directly into the flowerpot

spray spray

temperature exceeds 33 degrees, the rose will be in a semi dormancy state. At this time, water should be sprayed once a day and spray to the air and ground around the plant. p>

Maintenance

Illumination

Roses like light. Only when there is enough light can they bloom big and colorful. During the vigorous growth period, ensure the light duration of more than half a day every day. When entering the high-temperature and semi dormant period, pay attention to shade and avoid exposure

Watering

During the whole growth process of rose, there should be no water shortage. The temperature is too high, and the water evaporation and consumption of the plant are very large. Spray water to the plant every morning and evening, and water it every 2 ~ 3 days to ensure that the basin soil is wet

Fertilization

During the flowering period, apply rotten soybean cake fertilizer, chicken manure or compound fertilizer every 10 days or so, apply thin fertilizer frequently, and reduce fertilization in high temperature weather

Pest control

Pest

In summer, roses are easily infected by scale insects, aphids and red spiders, mostly due to high temperature and humidity, poor ventilation and poor light. After discovery, cut off the infected branches and leaves immediately, sparse the branches and ventilate, and spray them with 2000 times of 10% imidacloprid wettable powder

Disease

The common diseases of rose include powdery mildew and leaf spot. The diseased leaves and branches should be cut off first, and the diseased parts should be sprayed with Guoguang Yingna and carbendazim solution diluted 500 ~ 1000 times. It can be effectively treated once a week, about 2 ~ 3 times
