What kind of fruit should be planted on the enclosed balcony?

Strawberries, this one doesn't take up space either. As long as you master the basic planting points, it is easy to plant well. Fertilize more during the growing period, keep warm below zero in winter, or put it in a sheltered place. Some strawberries I planted have blossomed and produced more fruits from the end of winter to the next spring. Strawberries grown at home are much fresher than those bought in the supermarket. The joy of picking strawberries is hard to express in words.

Little tomato, this can be broadcast almost every year. If you don't want to buy seeds for fear of trouble, you can buy some directly from the fruit stand, take them out, dry them and plant them in flowerpots. However, it is also possible that there are not so many fruits because of the quality of seeds. But it can be used to practice hands first. I planted it several times and it all bore fruit. Yellow cherry tomatoes, red cherry tomatoes, large tomatoes and small tomatoes. All kinds of shapes can be seen as fruits and eaten as fruits. It's beautiful and delicious.

Blueberries, don't fertilize too much at a time. So is watering, general management.
