夏日极限操作，给葡萄柚换超大盆：透水层&盆土配置、浇水注意事项/Grapefruit Tree Repotting: Drainage, self-mixed soil & watering

After the initial period of acclimatization, the weather in Germany remained too hot for repotting, so I waited until the temperature dropped recently to do the job. Grapefruit trees grow rapidly compared to other citrus plants. Since I didn't have a pot with a diameter of around 30 cm on hand, I opted for one with a 35 cm diameter. Using a pot of this size for a grapefruit tree of this scale carries some risk, so I needed to be extra careful when preparing the potting mix and the bottom drainage layer. For this repotting, I once again used expanded clay pebbles for the drainage layer at the bottom. However, I used a larger quantity of pebbles this time; this approach ensures excellent drainage while also reducing the total volume of potting soil required. When mixing the soil, I included a higher proportion of perlite and pine bark mulch. Both materials offer good permeability, ensuring the grapefruit's root system doesn't remain in a constantly damp environment. Because I used such a large pot, the watering method needs to be adjusted compared to other citrus plants: I need to reduce the volume of water used and concentrate it around the central trunk area.
