Go in with a pick axe, work a small area when ground is dry. Do "patch" style. You have a chance of beating the choppers with a small patch of 8-10 fems. No trails, no hauling in a bunch of stuff. Plant seedling when they have 4th set of true leaves. Plant about 40 to get 8 good females. Leave and dont go back until June 20th. Sex and select final 10. Leave and dont come back until just before first big storm after October 10th.
Good luck, you will need it.
