I have an estimate to do this week that includes removal of a large area of dense, mature snake plants.(one side of a 4-plex and 20' wide) There are also other patches about 10X20. Is there a better way to kill them off than hand pull and rake out the rhizomes? This area is bad enough to warrant rental of equipment if that what it will take. Further complicating matters is Brazilian pepper and another spreading weed similar to a hibiscus in the area. On top of that, there are large oak trees in the mix that need to be unharmed. The peppers and other weed are easy to cut off and kill; but snake plants do not seem to respond to glyphosphate and would probably just come back up from the rhizomes...... There will also be some large areas to mulch... I'm thinking running all the stuff through a chipper and using it to get a good base layer down... any thoughts?
