This is an extremely important video if your apple trees suffer from canker. If you are early enough you can quickly and easily remove it however the longer you leave it the more it can spread. Steven (my dad) shows you how to identify and remove canker so that your apple trees stay healthy and productive.

Sir, I live in Himalayans in India. One of my orchard have lot of Canker problem from the past year. Not in Royal Delicious but new varieties like Super Chief and Scarlett 2. (2000m from sea level)
Most of the Canker is in main branch (leader). I can't just cut the whole tree. Is there any other way ?
I hv also got canker on my orchad..its 15-20 trees…how can i control..it..n stop from further spreading..
Thanks for the very helpful video!
Hi I liked your video. My question is.. Can canker start at the base of the tree? If so how do I treat it? I am finding a brownish jellylike substance at the base of my 4 year old Gala apple and I don't know what it is.
We had this same problem with our peach and plum trees. Thank you for explaining what to do about it!
Great video. Thank you!
there is so much information that we need to know, to check, to learn… my headach!! lol. but thanks for the video, it will help me heal my apple tree.
So i work on an orchard and we have over 350 hectares of dwarf apple trees and we are always having to deal with canker. A few things to mention are; Never cut in wet conditions (even cut canker out). Paint your cuts with prunning paint (most have properties to help stop canker). During prunning we don't worry too much about painting cuts smaller than your finger nail as we normally spray the block after with captan or prollific (i don't know what spray i don't do spraying). If canker is on a branch coming off the trunk we cut back atleast 10cm from canker infection area but most of the time just take the whole branch right back to the trunk. We spray our cutters with meths every time we cut off canker. For trunk infections we use angle grinders, with a modified blade which is more like a chain saw than a saw, to grind out canker. if there are 4 to 5 plus infected spots on the trunk we cut the tree down to just above where it was grafted on root stock so it's just a stump ( if root stock is infected and is too much to grind out we remove the whole tree). If the top of the trunk has canker we cut it down to a new leader which doesn't have canker. Hail netting which you rest ontop of your rows help cultivate canker as it increases humidity around the trunk so avoid using it if you can afford more expensive hail netting set ups. (we have taken hundreds of trailer loads of canker offcuts out of some of our orchards because of our hail netting). choose the right root stock for the soil type you plant on. A new block we planted had a clay soil (use to be a swamp centry or so ago), the trees had an m9 root stock (not very vigerous) and after 3 years have still not produced a crop but instead produced plenty of canker due to being too stressed because root stock needed to be more vigerous. If you spot it remove it; if it is on the trunk mark (flagging tape or spray paint) it so someone with a grinder can come along and easily find and remove it.
Why dose he wipe the diseased branch onto the cut area? He can get can of Lysol spray his tools might as well do his hands. Just quit cross contamination!
Which is good paste for Apple canker..
What about burning the canker spots with a small blow torch and sealing it?
I'm in Arizona. Diseases like this don't stand a chance in our desert climate. Wonderful information. Thx for sharing.
I am from INDIA. The canker problem is also in my apple garden. Please share the cheap & effective treatment to cure it.
I have one Ida red dwarf and just found out from this video it has caker on the graft !! so there is no hope !
I found the angle of your cuts to be overly severe. A cut that is perpendicular to the branch will be incorporated nicely into the new branch emanating from the bud that was pruned to. That being said, we all bring something to the art, and a successful outcome determines, reinforces, and perpetuates the technique.
have you considered praying the trees with Colloidal Silver? I tried it two years ago and the active canker has now gone away. I am going to try this year, using it to treat Black Spot once the flowers have set. As it will also give ongoing Canker protection.
When is best time of year to prune out canker for apples & plums? Do you recommend any proprietary wound heal to paint over new cuts?
Useful informative video. Make sure you check focusing to make sure the subject is in focus rather than the background, not a criticism, just advice.
Are there other diseases that look like canker on apple trees?
I have like a growth on the side of my apple tree, like collective round balls. Can canker be a large blob or mound ?
I am from india
enjoyable should do a tree first put the canker bits together show how much came off a tree, then do a tree how to
Dear Huw, Many thanks for sharing this video – I had not realised canker could be managed like this – very useful to know! Can you please offer any tips on the following? I have removed an old apple tree because of bad canker and wish to plant a new apple tree in the same place. Is there a risk it will pick up the canker from the old one? Is there anything I can do to prevent this? Thanks, Richard
Thank you SO MUCH!!!
thanks!

My 3 apple trees have cankers and fire blight from the rains in late august and most of september and may end up dieing next spring so I am ordering 7 new um,, disease resisitant ones. I have taken some cuttings from the 3 I have but they are not disease resistant because most of them are lodi apple cuttings.
Good, informative and clear video. Comments are also useful.
Thank you very much for posting.
