How to raise banyan trees
As a representative tree species of Lingnan bonsai, banyan trees are deeply loved by gardening enthusiasts for their vigorous roots and unique shape. Mastering scientific maintenance and pruning techniques can make potted banyan trees show more vitality and artistic beauty. This article will systematically analyze the key points of the entire process of banyan cultivation from environmental control to modeling design. The water management techniques for the core four elements of banyan tree maintenance adopt the principle of "seeing dry and seeing wet". Water is poured every 3-5 days in spring and autumn, sprayed in the morning and evening in summer to increase humidity, and water is controlled until the basin soil is slightly dry in winter. The dry environment in the north needs to be equipped with a humidifier to keep the air humidity>60%. Pay special attention to the difference in water seepage between pottery pots and plastic pots to avoid stagnant water and rotten roots. The light control plan ensures scattered light for more than 4 hours a day, and is protected by sunshade net from 10:00 to 15:00 in summer. Regularly rotate the flowerpot 180° to prevent branches and leaves from growing off the crown. When there is insufficient light, you can use a plant fill light to fill the light for 2 hours a day. Nutrient supply strategy Apply cake fertilizer diluted by 500 times every month during the growing period, and add bone meal + decomposed sheep manure as base fertilizer when changing pots. Starting from September, additional potassium dihydrogen phosphate will be applied to promote lignification. Pay attention to avoid concentrated fertilizer for the first two years of new piles, and add trace element foliar fertilizer to old piles. Environmental control points maintain the growth temperature of 15-30℃, and no lower than 5℃ in winter. Use 0.1% carbendazim to irrigate the roots every quarter, and wash the leaves regularly to prevent red spiders. Use a mixed substrate of red jade soil + river sand + leus soil (6:3:1) to ensure ventilation and water permeability. The best time to prune banyan pruning shape is advanced techniques for pruning. Re-pruning is carried out in late spring and early summer, retaining 3-5 main branches. Cut off inner branches and parallel branches at any time daily. A healing agent needs to be applied to a wound with a diameter of more than 1cm, and the trimming should be completed before the plum rainy season to enhance ventilation. The modeling design principle uses the method of cutting trunks and storing branches to create classic shapes such as cliff style and waterside style. Adjust the direction of branches by coiling aluminum wires, and loosen the anti-wire embedding every 3 months. Cooperate with picking to promote secondary branches, and use leaf phototaxis to shape cloud layers.
Master the key to "cutting in three points and feeding in seven points" and regularly observe the growth status and adjust the maintenance plan. It is recommended to establish a maintenance log to record the sprouting after each pruning. Through the combination of scientific management and artistic decoration, potted banyan trees will surely become a vibrant three-dimensional picture.
