soil

As the saying goes, if the soil is well prepared, the flower raising is basically half the success. This shows the importance of soil preparation to plants, especially the roses planted on the balcony.

Potted rose soil must be loose and well drained. It is best to use the cultivated soil made of rotten leaf soil. Horse manure soil or loess mixed with sand and sawdust can also be used (both horse manure and sawdust need to be decomposed).

The environment on the family balcony is relatively dry. In order to prevent the basin soil from being too dry, the basin should be of larger specification. Generally, it is better to use a tile basin with a diameter of more than 20cm. Ceramic pots are airtight and should not be planted with roses.

Ventilation and lighting

As we all know, the most headache for flower friends is ventilation and lighting, especially the closed balcony. Even some closed balconies with windows open all the time can't be saved

If the ventilation is really poor, flower friends can also aim an electric fan at the rose, or let the branches of the rose stretch out, climb outside and put them on the window~

As for the light, it's best to have a balcony that can receive half a day's sunshine. If it can't be reached, the planting of roses will be more suspended.

Seedling maintenance

Generally, the roses of Huayou are purchased online. After planting slow seedlings, that is, after the roses start to draw strips, you can add some liquid fertilizer when watering (huaduoduo, biwang, etc.). When the rose is in the peak growth season, bury some organic fertilizer around the basin. Huahua suggests to buy the compound fermentation directly, or retting it yourself, but it must be rotten before it can be used.

In addition, the balcony raises roses. Unless it is an open-air balcony, it's better to give up the idea of letting the roses bloom in a large area. In order to make the roses grow strong, it's necessary to pinch off the delicate flowers and seedlings appropriately, so that the roses can supply nutrition to a small amount of flower buds and branches.

Powdery mildew control

The outbreak of rose powdery mildew is generally regular. Spring and autumn agree with the outbreak, which is also a frequent visitor of balcony roses. The reason is that the air is dry, coupled with lack of ventilation, insufficient light, excessive nitrogen fertilizer and so on, the outbreak of powdery mildew is also appropriate.

In spring and autumn, more phosphorus and potassium fertilizers are used to promote the disease resistance of rose itself, and then strengthen ventilation and increase light.

And use certain drugs to prevent and control. Chlorothalonil should be used once every 15 days when the rose is not ill. If it has broken out, bactericide can be sprayed. 700 times the liquid of most bactericides sold on the market can be used for prevention and control. Triadimefon, mancozeb and manganese zinc can also be used alternately. Note that when preventing and controlling, you must spray all those white places wet in order to work!

Starscream control

Another big problem of raising roses on the balcony, Starscream. This is definitely a pain in the heart of many flower friends, but as long as the preventive measures are done correctly, it is not difficult to control Starscream.

Red spiders are usually produced under high temperature. Therefore, the most outbreaks occur in summer. The growth of red spiders can be significantly inhibited when the humidity is more than 70%, and they can hardly reproduce when the humidity is 80 ~ 90%. If it is a closed balcony, this method can be used. While increasing the humidity, avermectin of acaroid acaroid can be sprayed in turn, about three days apart in summer and about seven days in winter, Only when the eggs hatch can starscreams be killed, so they need continuous spraying.

Other precautions

1. The rose should be trimmed in time after flowering to avoid the residual flowers consuming nutrients on the branches.

2. Every time it rains, the rose should be thoroughly disinfected. Disinfectants such as chlorothalonil can be used to avoid infection with bacteria.

3. The best water for watering flowers is fish tank water. Generally, tap water and vegetable washing water can be used. Water should be poured enough at a time, not half a piece of water. It should be noted that the morning after a long rain should be watered with water, because the family balcony is rarely drenched with rain when it rains, and the surface of the basin soil looks wet. In fact, the soil moisture content is not much. If it is not watered, the roses will be damaged by the strong sun.

It's not that you can't plant roses on the balcony,

But compared with open breeding,

It takes more effort to plant roses on the balcony,

As long as you have confidence, even the balcony can grow beautiful roses~
