In urban areas, the choice of suitable crops is based first on the direction of the balcony. In general, the south-to-south balcony is suitable for the vast majority of vegetable varieties, especially cucumbers and tomatoes; the north-to-south balcony can be used to grow a number of chilly, low-lighted leaves, such as lettuce, cabbage, celery, onions, cuisine, etc.; and the east-to-west and west-to-west balconies, where most vegetable varieties are optional. If there is little experience in planting, it is recommended to choose to grow faster and manage simple vegetables。
The balconies are grown with limited roots, and the roots of the crops in the planting containers are limited in terms of the growth space and the intensity of the water and fertilizer supply, and it is advisable to choose either a specific planting matrix, such as nutrient soil, or, as far as possible, a relatively fertile garden. In fertilisation management, it is recommended to purchase a combination of nutrients, which can be regularly ploughed in accordance with the instructions. In cases where soil is grown, some organic or earthworm fattening acids are used to increase soil fertility and air-resort water performance, and short-lived production can be avoided。
With modern technologies in place, home-grown vegetables are hardly too restricted. For example, light conditions are not ideal, with easy-to-move plantations, etc., moving to full light during the day, with the condition that vertically mobile lights be used to compensate for the light with balcony lighting。
I'm going to have to work hard to plant good food on the balcony. For example, diversification helps to mitigate the occurrence of pests and diseases; successive harvests of vegetables such as cucumbers, tomatoes, etc. Need to be followed up during the outcome period, with the condition that they be supplemented with a full amount of nutrient better; in cases where they are properly managed, they can be collected many times, for example, in the form of carnal acids, purple sunflowers and beryllets。
Waiting for the fruits of small seedlings is a test of skill, patience and an extremely “healing” process. Seeding, caring, believing that the pleasure of “sharping and reaping” will be felt and the “dreams of the field” will be realized under the “foundation of the quest”。
