Cucumber is a vegetable that everyone likes. It can not only be made into delicious food, but also has the effects of beauty and weight loss. Friends who have balconies at home like to plant some plants or vegetables on them. Recently, a flower friend who likes cucumbers asked the gardener, "Can we grow melons on the balcony in winter?" How to grow cucumbers on the balcony in winter? " Next, Uncle Gardener introduced how to grow cucumbers on the balcony in winter. 1. The sowing time of cucumber on balcony is usually in early spring1-March. 2. The selected cultivation containers include flowerpots, wooden pots, professional cultivation boxes and foam plastic boxes. The depth of the plough layer is about 40 cm. 3. Put the cultivated soil for sowing into a pot, and after watering it, sow 2~3 seeds on demand. 4. Sow the soaked seeds evenly on the intensive soil, and then cover with a thin layer of soil with a thickness of about 1cm. After about 5 days, cotyledons will grow out. After this leaf grows, the seedlings will become thinner, and before this leaf grows to 2~3, it will leave the healthiest seedling. 6.2~3 leaves grow out, plant them in a pot, carefully take out the plants in the pot, and be careful not to let the soil at the root fall off. It is recommended to use synthetic resin with good water retention for planting containers, and leave a spacing of about 15cm between each plant. Sufficient base fertilizer, mainly decomposed organic fertilizer, is needed when planting, and it should be combined with watering and fertilization in the fruiting period, and the compound fertilizer can be applied once every 5-7 days. 7. When the leaves grow thick and the vines grow out, you can set up a column and fix the stem and the column with the figure-eight ring tie method. You can also tie a rope between the pillars to facilitate the climbing of cucumber vines. It is important to grow cucumbers on the balcony. Matters needing attention in planting cucumber on balcony: 1. Cucumber root system has weak absorption capacity and is sensitive to high concentration fertilizer. Top dressing should be applied with thin fertilizer frequently, once every 6-8 days, once after the first batch of melons are harvested, and the soil should be cultivated and fertilized. Pay attention to phosphorus and potassium fertilizer to avoid steep growth and premature aging. 2. During cucumber planting on balcony, it is necessary to keep the growth temperature at 20-28.
