How do you permanently kill six walnut trees?

Question

Squirrels are spreading them everywhere and it is illegal to see the wood from Walnut trees in East TN.  I have tried stump killer and rock salt but this failed to kill them.

I've read that if you drill holes in the roots and pour in some Roundup it will kill the tree.

So far I hv not had a problem with walnuts. I had several trees cut last year and around 10 were walnut. I want them to grow back so I can harvest them again in 10 years as walnut brings more than other trees.

A family member has his own tree trimming/cutting business. I recently asked his advice about how to kill the invading roots of a tree we are going to remove. (I would have him do it but he lives two states away). He said use Round up on the stump. Spray it well and then wait a week. Spray it again and wait a week, etc. he said to do it at least three times. The roots will absorb the Round up from the stump and die.

I have tried Roundup, stump killer, Epson salt, cutting the tree down and nothing seems to work. They keep coming back & dropping walnuts for the squirrels to plant everywhere,

Bill R. · Answer

I have the exact same problem, not only do the squirrels drop them, they roll into or down to any spot that will root them, and the roots travel and are almost impossible to get rid of. Cutting them down and immediately wrap the stump with aluminum foil and try to band it to hold in a mix of salt, preferably rock salt as rain will dissolve table salt too quick, and a good weed killer or stump killer and cover with a cloth to stop heavy rains wash away the mix and allow just enough water to seep to the roots. Apply this several times a week for an amount of time that it causes the stump to turn gray looking, that will be how to tell it's dead. You have to keep applying as this is one tough tree to kill. Usually seedling sized ones will die if pulled before matureing if you get the whole tap root, if not they'll be back.

Bill R. · Answer

Oh, and as for the larger trees, you need to cut into the center of the stump by making a divet deep enough to hold whatever you are using, but remember, persistence is the answer, you have to keep applying the killing product until you see results, the greying of the wood.
