1. Can a grafted plant stay on the root stock indefinitely or should it be separated at some point? And if so, when?

2. In a c&s show are grafted plants frowned up?

3. If a plant was once grafted but later separated from root stock does that have to be disclosed in a c&s show?

4. Is grafting something I should get into if I want to grow prize winning plants? It intimidates me a little, but sounds interesting.

Your help is greatly appreciated,
Robin

1) IMO&E, it should be - 'Fred' can be grown on its own quite easily, once it's (the scion) outgrown the stock.

2) Usually covered up by strategic potting / top dressing in a / for a Show.

3) Thank you for a question about the details - I would say it depends on what it's growing as at the time of entry - a grafted plant or not.

4) Grafting does put a jump start on slow and slow-and-difficult plants, to get them to maturity / flowering (and seeding) size, there's no doubt. Additionally, most new species (I can think of Digitostigma as a recent example) are grown on grafted stock to get them to maturity / flowering size / pupping/cutting size more quickly, and it works for that reason. For others, it's aesthetics aiding / preventing them.
