I wonder if anyone can advise me on the planting of a grafted Wisteria Floribunda Rosea. Jenny ordered 2 of these from Van Meuwen and they arrived today, 7.5cm pot size. They're both grafted but there are no specific instructions on planting with the graft above or below the ground. I've googled but some say yes plant with the graft below the ground as per roses and others say no plant with the graft above the ground......

When I had mine I read that the graft should be above ground as the rootstock has a tendency to throw up new shoots which will be far more vigorous than the grafted plant. Not only can they throw up runners off the stem they can evidently throw them up from the roots so it is worth keeping grafted plants in a container I think. I'm no expert though, and I failed to realise that s & s love the new buds, mine was stripped bare before it got going in it's second year and the main stem never recovered.  I now have three suckers growing from the rootstock and will see what happens with them over time. |

Ladygardener, from the RHS (quote): 'Avoid over-deep planting. In the majority of plants, the graft should stay proud of the soil or be positioned just below the soil level (roses). One of the exceptions are tree peonies where the graft should be below soil level.' It would seem then that the graft should be above the soil. It also says: 'When mulching, keep the base of the plant free from mulch.' This is part of the section of an article on graft failure so it is obviously important.

Tig, this extract from the above article may be relevant to your post. (Under Symtoms ... ) '•The rootstock often remains alive and may produce suckers. Sadly, the rootstock is often of inferior quality to the plant that has died so it is seldom worth trying to grow it into a replacement plant.' Of course, you never know ...

It's the 'you never know' bit that I'm clinging on to Ron  |

Tig, Ron, thanks very much for your help. I'll keep the graft above the soil.

Sorry Ladygardener, - I have been busy - I would say above as well...it was something that Olaf said to me years ago...not sure anymore what it was but it was about grafting. I have in mind roses down, wood up...which is probably my screwy mind saying rose graft under the ground , the rest above.. |

Rosefriend, thanks. I've just potted them on for Jenny and have kept the graft above the soil.
