Second, the family balcony vegetable garden environment
1, soil cultivation
To grow vegetables in cities, it is necessary to confirm the history of the soil used. It is best to dig some safe soil in the suburbs, rather than choose polluted soil. The best way is to choose special culture soil according to the types of vegetables in the farmer's market.
2. Soilless culture
If it is really difficult to identify whether the soil quality is qualified, it is recommended to use soilless culture and tap water for cultivation. Soilless culture has the advantages of fast growth, high yield, good quality and less pests and diseases. It only needs to be watered with nutrient solution, which is very convenient to manage.
Three, the balcony vegetables matters needing attention
1, there is too much water.
Like flowers, many vegetables can't be raised well, and the most rare reason is that they are watered too often. Most vegetables should be watered according to the principle of seeing dry and seeing wet. Especially in the seedling stage, frequent watering will lead to the growth of vegetable seedlings in vain, and more seriously, it will lead to the death of vegetable seedlings.
2. No topping in time
Many fruits and vegetables need topping. Cutting off the growing point at the top of the plant is called topping, also called coring. It may be ineffective to prevent plants from growing too tall. Some enemies who plant fruit trees at home must stop topping in time if they find that the saplings only grow tall and have no side branches.
It is a good idea to grow vegetables on the balcony, especially for the elderly at home. Give them something to do and let them pass the boring time. After all, most of us are busy with work. The vegetables recommended above are very suitable for planting on the balcony.
