Can vines be potted?
In the urban gardening craze, grapevine potted plants have become the new favorite of balcony planting. Through scientific management, pots with a diameter of more than 40cm can achieve a bumper harvest of grapes, which can not only create a three-dimensional green landscape, but also enjoy the fun of fresh fruit picking. By mastering key technologies such as pot soil ratio and light control, window sills can also be transformed into miniature vineyards. Feasibility analysis of grape potted plants 1.1 Spatially adaptable modern dwarf varieties such as "Xia Hei" and "Sunshine Rose" can be controlled within 1.5 meters with regular pruning, making it especially suitable for planting in pottery pots or wooden boxes with a diameter of 40-60cm. 1.2 Cultivate advantageous potted grapes with ease of movement. They can be moved indoors to prevent cold in winter, and can prevent cracks and rain during rainy seasons. They are easier to control pests and diseases than local planting. Core technology for grape potted plants 2.1 Cultivation system Build green mountain pots or pottery pots with strong air permeability, and match them with T-shaped/grid brackets. Lay a 5cm ceramsite layer on the bottom of the basin, which is better with an automatic drip irrigation system. 2.2 The ideal ratio of the substrate formula is garden soil: leaf soil: vermiculite =5:3:2, and 500g of bone meal is added per cubic meter. Keep 1/3 of the soil when changing pots every year. 2.3 Light and warm water management Ensure 6 hours of direct light in spring and autumn, and use 50% sunshade net for protection at 10-15 o'clock in summer. Use the "see the dry and wet" watering method to maintain the air humidity of 60-70% during the fruit hanging period. 2.4 The precise fertilization plan applies nitrogen, phosphorus and potassium 15-30-15 water-soluble fertilizer during the germination period, and uses high-potassium type 10-15-30 after fruit setting. Calcium and magnesium fertilizer is sprayed on the leaves every month to crack down on the fruit. Advanced maintenance of grapevine potted plants adopts the "single arm" shaping method, retaining 6-8 short shoots every winter. Artificial pollination at flowering stage can increase the fruit setting rate by 20%, and the best quality is to retain 50-60 fruits per ear.
Through 3-5 years of fine management, potted grapes can produce 3-5kg per year, which can not only experience the fun of planting, but also harvest safe fresh fruits. Regular replacement of pot soil and renewal of fruiting mother branches can achieve sustained high yields of balcony grape trees.
