Hello! I am hoping that someone knows a means of killing off caragana. We have an older home, and both the front and back of the property is framed in with old, overgrown caragana (I wouldn't mind it so much, but it's over 6' thick in places and has gotten covered in a silver mildue both summers since we moved here, not to mention the prickles). It's also dispersed through-out one long flowerbed on the side of the property. I've tried to dig out the stuff in the flowerbed as it looks like it was chopped down a few years ago, and is mostly rotted stumps and some new small growth...I found out that the "small" growth (about the diameter of a finger) has roots that go straight down over a meter...yeah! My husband tried to pull out the front stuff with chains and a 4X4...I bet our neighbors think we're rednecks...but that didn't work either. Round-Up also doesn't seem to have much effect. Does anyone have any other suggestions?? I'd like to eventually make our yard a 'caragana-free' zone.

Hi Verena.. sorry to say but apparently from what I gather it is basically impossible to kill caragana, and since pulling it out doesn't work with those roots you say, my only other suggestion to you since you said you wouldn't mind it but it is in bad shape... would be to rejuvenate it.. cut it right back to the ground all the old or diseased canes and new healthier growth will appear and then you can shape it as you want, also i should say they recommend to only cut it back by a third every year for 3 years, and do this is very early spring, before any leaf shoots appear. Sorry this is all i could think of to try to make this bearable for you. Although... now i don't have a clue if this would work or not but maybe they say to cut back by 1/3 because anything more could hurt/kill your bush.. what about cutting it all at ground level and covering with black plastic or something for a year or so? Anything growing that doesn't get light/air would surely eventually die wouldn't it?? Like I said i have no idea, it was just a thought, otherwise maybe just try to get them in better shape like i mentioned.. Good Luck to you, sorry I couldn't give a better answer.

Thanks for the tip. I'll try the black plastic...The plan is to put a latice fence in this spring, on both the front and back (so our little guy can't find his way onto the street) so keeping the caragana isn't an option, but I should be able to tarp off the caragana under the fence and around the posts once the fence is in, and once it looks like it's dead then the area will be getting turned into flowerbeds on both sides of the fence. (I can hardly wait to get to that phase.) Thanks for the advice!

In the south Whiteshell area of Manitoba we have a terrible problem with caragana. Someone planted a hedge 50 years ago and it has now spread through the forest and has completely destroyed some cottage properties. Proof that we should not introduce non-indigenous plants to a pristine area! But,we have found a chemical called "diphenoprop" or "estaprop" available from a local ag. dealer. Sorry I don't know who produces it. It's not cheap, but can save your property. In order to kill the caragana you would have to paint completely around each stem to a width of about 1 ft. However, dealing with such a vast number of plants you should cut it down to about 1 ft. in summer and then in the following spring when it leafs out again start at the back of your property and work your way out, painting completely around the stems of all branches of each plant. Do be very careful when using this chemical. Buy very thick rubber gloves from a farm store, and wear a mask. Wash your jeans right away. A lot or work! Good luck.
