What herbicides do you prefer and at what ratio for the hack and squirt? Also what time of year is it most productive?
9 oz of 53% mixed with 23 oz water, ( use industrial squirt bottle) hatchet works best in my opinion, ( eastwing handles are best) 1 hack per 4 in dbh, do not overfill gash with herbicide. spray chem on blade and let it run in to gash . I hit some species more like beech,soft maple, olive, honey locust, and sour wood, i want them gone.
do not overfill gash to where it runs out.
if a small target tree is close to a money tree, i dont use chem , jut hack it around a few times, i will hurt it enough it will eventually die.
when you get the hang of it, you can do 1 ac per hr on average, I just finished for the year, completed 190 ac. best time is fall , late summer. but any time after full leaf out and up to sap moving.
I worked on my place in tn last year up till feb and still had good results.
hope this helps
