Anyone know of a suitable product for a patch of cut and partially regrown bamboo? It's under a sparse beech and birch canopy, not much else on the floor as it has been so thick before our first cut.
Cheers

Timbrel , i believe is still one of the best ' scrub ' herbicides , very expensive though so normally only used on priority type situations .

If you have the time there is also this alternative.

Spray the Bamboo with roundup and give it time to take then mow the Bamboo down. Keep doing this until the Bamboo uses all its food reserves and hey presto, it dies. Try not to let it get too much green on otherwise it's making food and make sure yo get every single bit. I know a couple of people who have tried it and it works pretty well without having to apply those expensive chemicals.

Cheers guys, have sprayed with roundup 450 having left it to have 2-3 leaves per stem. It's been 2 weeks and no signs of dieback. Might give it another week and run through it with a brush cutter and then give it another dose of roundup on the initial regrowth.
Looks like its a bigger job than I expected

If you are using Roundup I would say that it would be better to allow a fair bit of regrowth to occur first. More leaves = more surface area to absorb the chemical. I have certainly found this works best with rhododendron regrowth anyway....

If you want to get rid of it fast about the only option is to dig it out

Hi there, BTT is spot on Timbril is the stuff.

How deep do you need to go with bamboo, are they very deep rooted ?

I need to dig out an old lawn to put in a garage base that has a lot of bamboo growing in it , having spread from a large clump in a neighbour's garden, and don't want it regrowing through the concrete.

Broadsword is a cheaper alternative to Timbril, similar composition, have used in the past with great success on Japanese Knotweed, Bramble, Gorse etc. Last time I brought some was about £75 for 5 litres, and that goes a long way. Would imagine it will do a good job on Bamboo too.

Also may be worth contacting Agri-chemical dealers / merchants and asking the agronomist what equivilants there are to Timbril, there may be a few products on the market that do the same job and contain the same active ingrediants but for less cost.

Probably worth applying with an adjuvant for that extra bit of take on something like Bamboo.

I have cut down and stump ground bamboo at the request of a client - I assume it worked never got a call back - granted its not the orthodox method but easier than digging it out.
