I have a plum tree in my garden which has been growing vigorously, but entirely fails to produce any fruit.
I was planning to cut it back hard and graft some things onto it.

Any thoughts?
When would be best to cut it down?


iirc plums need chums to pollinate them.

Thank you for this article. Can you tell me if you do the same for plums and if so, what rootstock should I use (and where would I get it from)?

The rootstock for plums is st julian, available on ebay. Window for grafting ends march. Same grafting techniques can be used.

Some e-bay rootstocks I've seen have been on the thin side for successful grafting.


Too late! Sounds okay, will just have to see. It's more likely to fail because of either my incompetence or because the tree is too far gone!

Hi guys - great to see it finally!

Yes, not just apples, but basically all fruit can be grafted. Id stick apples to apples (but any kind), pears to pears, and plum rootstock can take plums, sloes, damson etc...
Ive done budding too, and its been even more successful, so if your grafts done take in Feb then you get another bite at it in July and August for budding.

re grafting tape - I use parafilm, but any film is good - its the tightness thats important. PVA glue? Dont think so - you wont get a tight enough quick fix.

The one really important tip to mention is - when you cut either grafts, scion or budding material DONT let your skin touch the cut surface - otherwise you wont get it to take.

Look after the root stock and you can graft again the following spring.

PVA glue is not waterproof either, so will wash away before the graft has taken.

I should clarify. I wrote that before seeing your article. What is new for me is to do a small strip of parafilm to hold the graft in place (and seal it) and then to use a larger piece of parafilm to wrap the entirety of the scion (sealing it from transpirational losses of water). The glue trick is to do the same (small strip of parafilm to hold the graft) but to paint on the glue around the scion and over the graft union. This also reduces transpirational losses.

I haven't done enough to say anything with confidence, but both methods look promising. They should yield higher success rates.

The waterproofness of PVA isn't really an issue if the new grafts are being cared for in a polytunnel, etc... as the scion should be leafing out through it by the time it's moved to an exposed area with rainfall.

Obviously we do things differently either side of the pond. I think from what you describe you are aiming to use the PVA in a similar way that wax used to be used for grafting here. I think it may be better for budding.

Wouldn't the wax have just been applied to the cut end at the top of the scion? The parafilm wrap, or glue paint job would coat the entire scion to reduce water loss.

I don't have any data to state that it's better, but it's worth experimenting with if you're curious!

no, over here I dont actually do anything to the cut end of the scion thats at the top, just wrap the bottom bit thats being fixed to the rootstock. Also, leaving the whole of the scion (apart from the wrapped bit) lets me 'see' if the wood is alive and has 'taken'.

More questions. I didn't expect the root stock to arrive until next year but apparently I can expect them this weekend. What do I do? I am thinking pot them up and wait until next year to identify decent bits of the plum tree that I'm hoping to graft from or do I get on and do that this weekend?

It's temporarily stopped raining but it's a slight struggle standing upright in the wind.

They will be fine heeled in somewhere sheltered.

Grafting wax was traditionally used to seal grafts before plastic grafting tapes became popular.
Grafts where tied then waxed.
Tape saves the bother of having to carry a burner to melt the wax & there's far fewer health & safety issues. It is as Slim says also used on the exposed cuts to reduce transpiration.

I've used electricians insulation tape with success - secret is to make it as tight as you can to press both cambium edges (rootstock and scion) in as close contact as possible.
