Anyone have a remedy for crepe myrtle suckers,other than manually wringing them off? I have to do this 4 or 5 times a season,and advancing age and general outofshapeness is really making it a tough process.Thanks for listening.
I do the lopper and pruner thing also.I was hoping for a chemical answer.I remember as a kid,we were forced to "sucker" tobacco,and when we broke the sucker off,we squirted mineral oil or something called MH30 on the break,preventing the return of new growth at the sucker point,without damaging the plant.Thanks again.
I use a Glyphosate based weed killer for everything, buy it in the concentrate form so can mix it up to the required strength myself. only thing is that it's a non-selective herbicide, so will kill everything.
When just spraying grass and young broadleaf weeds (before they've developed a thick waxy layer (cuticle) on their leaves) mixing at 1 litre per hectare works great. However when there's more meaty stuff to kill, I mix at the maximum reccomended dose rate....5 litres per hectare.
With this i've managed to wipe out small tree (ash, sycamore, oak) saplings, ground elder, weeds over 4 foot tall, not found anything that survives a good dose of this. A small squirt of detergant in the mix also helps as it breaks down the waxy layer on the leaves....allowing the chemical to be absorbed better.
...would only do the above if you're intending to get rid of the plant from your garden though.
if you're intending to maintain an established shrub without suckers, you can buy a chemical called 'sucker stopper' which you apply to the open wounds left from cutting the suckers off, prevents them from reappearing.
Type it into your search engine, bound to find lots more out on the net if you're interested
I have 2 of them shaped into trees. For 30 years I have been cutting off the shoots at the bottom. The roots sent them up. They can come up several feet away from the trunk. Just one of those things you got to do. I have not found anything to stop them from coming up.
