I heard of a propane torch to Kill weeds.How effective is that on long rooted weeds and where can I buy it? Does Home Depot carry it ?

Yes, you can torch weeds to kill them. The key is to lightly pass the flame over the foliage to burst the cells in the leaves, not to incinerate the plant. When you slightly scorch the leaves, they will attempt to repair themselves, drawing energy from the root systems. When the stored energy is depleted, the entire plant will die. If you incinerate the weed, the roots will use the stored energy to produce healthy new leaves. Weed torchers are available at most garden centers and should be available at your local Home Depot.

Good luck with your weeds!
