Bacterial Canker on Sweet Cherry Zone 9B San Jose California
I searched this forum and found a few posts on this topic.
Recommendations where -
- To remove the tree (if canker is on the central stem)
- Apply DuPont Kocide 3000 / copper
- Remove the infected branch or cut out the wound and seal and spray
My sweet cherry on z-dwarf (Planted in spring 2015) started developing a huge canker right at the base where rootstock touches the soil in spring 2017. Now in Jan 2018 I see Canker & gummosis right on top of the tree where the pruning cut was made in 2015.
Tree seems healthy otherwise.
My initial plan was to keep the tree and plant new cherries next to it (5 feet away). Is this a bad idea? Will it spread to the new trees? )My neighbors sprinklers spray on the trees when windy )
Should I pull out the tree ASAP, burn them and treat the area with copper - before planting the new trees?
I would hate to lose 3 years of growth on this cherry
Appreciate any inputs!
