A. Substrates for epiphytes:
1. Standard mix, proven, especially recommended for beginners: Osmunda, Sphagnum, Beech leaves 4:2:1.
2. Variations, tried and tested and recommended:
Osmunda, Pine bark, Sphagnum, Beech leaves 3:2:2:1.
Pine bark, Sphagnum, Beech leaves 2:2:1 (after Elle, That).
Polypodium, Sphagnum, Pine bark, Beech leaves 3:3:3:1 (after Elle, That).
Coke, Sphagnum 1:1.
For small-growing orchids for mounting on bark: Polypodium, Sphagnum 3:1.
Cymbidium mix: peat, half-rotted foliage soil 1:1, some addition of coarse sand.
According to Elle, That: Oak trees- and beech leaves, Sphagnum, Pine bark, Addition of coarse rocky clay or turf soil, Bone meal, Hornspäne.
Mixture for Coelogyne, Lycaste u.a. Genera and species, which require some humus proportions: Osmunda oder Polypodium, Sphagnum, half-rotted leaves 2:2:2. Peat substrate for Phalaenopsis, Dendrobium phalaenopsis u.a.: Grobfaseriger Sphagnum-Torf, Addition of 3kg carbonate of lime per m³, 1,5 to 3 kg complete fertilizer with trace elements.
B. Substrates for terrestrial orchids:
Essentially, only Paphiopedilum come into consideration here. In terms of their composition, the plant materials used have almost even greater contrasts than the epiphyte mixtures.
Standard mix, to be recommended as universally applicable: Osmunda, Polypodium, Sphagnum, Beech leaves 2:1:2:1.
Mixture for robust growing species and hybrids: Osmunda, Sphagnum, coarse-grained Rasenerde 2:2:1.
Torfsubstrat: grobfaseriger Sphagnum-Torf, Sand, Addition per m³ 1,5 to 3 kg complete fertilizer with trace elements.
Mixture for calanthe: Osmunda, Polypodium, Sphagnum, Rasenerde, Kuhdünger 1:1:2:2:1.
Mixture for both epiphytic and terrestrial orchids:
A: 1 to 3 Volume parts STYROMULL or. POLYSTYROL, 1 Part of Sphagnum
B: 2 Volume parts STYROMULL or. POLYSTYROL, 1 Part of peat, 1 Part of Sphagnum
