How to raise Japanese roses
As a treasure among miniature roses, Japanese rose is deeply loved by flower friends for its exquisite plant type and continuous flowering characteristics. This seemingly petite plant actually contains strong vitality. Mastering the five key maintenance tips can make it bloom with stunning beauty within every inch. 1. Select the basin material and choose the red pottery basin or purple sand basin with good air permeability. The bottom must have drainage holes. The diameter is controlled within the range of 15-20cm, and the basin height and crown diameter maintain a golden ratio of 1:1.2. The timing of pot change is judged when the root system is drilled from the bottom hole or the pot soil is hardened. The best operation is in spring and autumn. Keep 1/3 of the heart soil, cut off the old coiled roots, and move them into a new pot. 2. Soil blending secret substrate gold ratio uses a mixed substrate of humus soil: vermiculite: perlite =5:3:2, and adds 5g of decomposed sheep manure to each liter of soil as the base fertilizer. Add vermin cast water-soluble fertilizer once a month. Acid-base balance control is regularly tested with pH paper and maintained in a slightly acidic environment of 6.0-6.5. It can be adjusted with diluted white vinegar water (1:500) or ferrous sulfate solution. 3. Light and shadow control rules Ensure 6 hours of direct light in spring and autumn, and use sunshade nets to filter strong light from 10:00 to 15:00 in summer. Full sunshine maintenance can be carried out in winter, and the light can be extended to 8 hours with a fill light. 4. The dry and wet cycle skills of the smart water supply system adopt the "fingertip detection method": the index finger is inserted into the basin soil for 2 cm and poured thoroughly when there is no moisture. In winter, use long-spout pots to supply water along the edge of the basin to avoid frostbite on the roots. Key points for water quality treatment use tap water that is dried for 3 days and irrigate EM bacterial solution once a month. Potassium dihydrogen phosphate (1:1000) was added before flowering to promote flower bud differentiation. 5. Immediately after shaping and trimming the artistic flowers, cut off the residual flowers and the 2 compound leaves below to retain the buds that grow outward. Retraction pruning is carried out every spring to maintain the mushroom shape within the 30-cm crown width.
Mastering these five core techniques, Japanese rose will continue to bloom on your balcony for 300 days. Regularly observe the status of the plant and adjust maintenance strategies in a timely manner. This miniature rose will definitely be rewarded with blooming flowers.
