If this looks familiar, it is because it is the second big camellia to be killed here in the same manner in not much more than two months. The damage is not fresh, likely because the gopher that caused it started chewing on the roots as soon as the other camellia was removed. The other camellia succumbed about two months after a similarly damaged cherry tree was removed.
We are now concerned for a remaining third camellia in the same spot, as well as others in the vicinity. There is also concern that the gopher may take interest in something else, such as the birches. We would typically find and destroy any gopher that causes such problems. The difficulty here is that the area is thoroughly covered with a dense layer of Algerian and English ivies.
All evidence of gopher excavation is obscured. Even if we could locate such excavation, it would be very difficult to cut through the thicket of ivy without collapsing the tunnels that we would need to put the traps into. It would be excellent to get rid of the ivy as well as the gopher, but that would be a major project for another time. As voracious as gophers are, they don’t eat ivy!
For now, we can only watch the adjacent camellia and other camellias in the vicinity for distress. Of course, by the time a problem is noticed, it will likely be too late to do much about it. We could only apply blood meal, and hope that it works as a repellent. These camellias get blood meal as fertilizer anyway, so would only need more applied off schedule and around the trunks.
The remains of the deceased camellia were removed from the site, and respectfully interred into the green waste recycle bin.
