No master class unfortunately lol.
Some tips I can offer through many years of showing my awarded cattleyas.
Staking Cattleyas:
1. As buds are developing, separate the buds with stakes to widen space. This is best as buds get to 80% mature (Before that the buds and ovaries are too firm to move). This prevents the bunching and crowding. During this time you can stake the entire inflorescence too.
2. If only 2-4 flowers, separate in a row. If multifloral, stake straight up.
3. If flowers rotate upside down, you can gently manipulate it by twisting the bud and bud stem aka ovary (not the main stem where ovary attaches, or you will detach it by mistake!) Give a gently turn by twisting 10-15 degrees back and forth about 5 times into the direction you want. Repeat 2-3 times a day over a few days. Preferably done just before the buds open. Can be repeated as flower opens too. But carefully! Tip: hold the ovaries on each end to twist the middle ovary part is best. Or one end on the ovary base (near floral stalk) and other end near or on bud itself (extra careful on the latter to avoid shearing off the bud).
4. Each individual flower can be twist tied to hold in place as well, particularly if they nod downwards. Discretely is best so nothing is seen.
5. Repeat with other inflorescences to achieve a 360 view if possible. If not, then all facing one semi circle is good too.
Many cattleyas are staked as an afterthought and it shows by flowers that are crowded and wrong side up, with many twist ties. This detracts from the 'natural' beauty of the flowers sometimes. Best to prep as the flowers develop. Takes a lot of practice but its worthwhile to showcase your babies (and skill).
