Thanks, Maya for the spray info. We have no red cedar around us for several miles minimum, so CAR shouldn't be a problem. Camp location is a mountain top in N.C. Pa. Our planting method was to strip away a 40"x 40" square of sod, plant tree w/ added black, aged mushroom compost, put down landscape cloth equal to the 40" square. Then we wrapped the trunks w/ aluminum window screen ( stapled ) and piled 3" of pea-sized limestone gravel on top of the landscape cloth. The whole spot was then caged w/ 5' tall concrete mesh and staked w/ 1/2" re-bar. We applied 10 gal. of water over 2 days when planted. Since our location is remote, I drilled ( 4 ) 1/16" holes in the bottom of some 5 gal. buckets to put at each tree location on top of the gravel. When filled, the buckets slow-drip water to the trees over about a 12 hour period. The buckets were placed AFTER the initial 10 gal. watering at planting weekend.
The camp is an old farmstead with plenty of field area. The trees get lots of sun and plenty of breeze. We have a tractor & implements which we plow, disc, pack our food plots with. The apple trees were all planted in those field areas which will NOT be food plots. Don't want to chance root damage to them. Only mowing with tractors ( grass w/ a little clover ) around the apple trees. That's our situation. I thank you again for the expert advice on spraying. I'm going to try to get some pix of the trees next trip up to camp.
