easy way to grow in trees i have done before

get some strong firewire fishing line the kind that dosnt get fuked up by the sun make sure it has a string breaking strain like 50 lbs or more and a few coat hangers or strong hard wire and a few good sized light plastic pots get the line putting a heavy weight on in and toss to highest branches you can find then put 4 holes in the pots and loop the wire through them then in the centre tie the line on the wire and after you put seeds in or small plants pull the pot up through the tree getting as close to top as possiblethen with the other end of the line strak it onto the tree then mix a small bit of dirt/mud rub over the tird off wire hiding it
put plenty of water saver crystals added to the pot
