How should the surface of a potted orchid's potting medium be managed?

1. Steamed-bun shape:OrchidsThe pseudobulbs and the upper part of the root system should sit 2-3 cm above the rim of the pot, and mud should be gradually firmed up layer by layer to build a curved mound surface. This type of surface is suitable forCymbidium goeringii (Spring Orchid)andCymbidium faberi (Huilan), and medium and small plants of autumn orchids. 2. Horseshoe shape: when building up the pot surface, gradually firm the soil from the pot rim into a horseshoe shape along the curve. Because this surface has a gentle slope rising on all sides, a thick and broad raised layer of soil, and a top that is flatter and broader than the steamed-bun shape, it is easy for air to circulate and moisture to stay even, so the plants grow vigorously and readily produce flower buds. It is suitable forCymbidium goeringii (Spring Orchid)andCymbidium faberi (Huilan)with well-developed, long root systems and many leaf clusters. 3. Slanted shape: the curve on the front side is smaller than on the back side. This form is suitable for planting medium and small plants with only two or three leaf tufts, or those separated off after division, as well as cases with many small plants attached to a cluster of pseudobulbs. 4. Flat pot surface: the potting medium surface is flat. This form is suitable for planting ordinaryorchidsor rooted pseudobulbs separated off during division propagation, as well as thin, short plants. In addition, summer orchids, autumn orchids,Cymbidium kanran (Cold Orchid), New Year orchids and the like, because they grow strongly, use coarser soil, and are highly adaptable, are mostly planted with a flat pot surface.
