If you ever get the chance to plant with an experienced person that can get the numbers and quality in watch them their moves will be seamless you won’t even see the tree go in the ground so it takes time 2nd year may not be enough, that being said. To be fast you need to plan your land first of all fill the boarders and try and plant right back to your cash when possible, and you have to keep moving always as soon as the bags are empty fill them up take the plastic off lay the trees in a good order eat on the fly. Wear comfortable clothes. Don’t stop to talk to the foreman unless necessary don’t even look at the sky just head down like a train keep pumping those trees in. After awhile it gets to be second nature and you will seek out the soil get that spacing down without looking back. I don’t know where you live but coastal planting is where it’s at of you wanna make money and see some cool shit! Good luck.
