Here are some soursop 3 years old, over 6 ft tall in 3 gallon pots, They are growing faster than the ones in bigger pots. The trick is to have a good base such as concrete or plastic to keep the roots from growing in the ground, add about 6 inches of a mix of fresh and composted leaves mixed with peat moss and stick the plants on top, it allows for the roots to grow out the bottom of the pots and sit in a rich moist compost while keeping the top roots more dry, since the peat moss stays wet longer it gives you a couple days in between watering, plus it saves on fertilizer as it accumulates around the base instead of going in the ground.


here are some Bignay over 6 feet in about 2 gallons of dirt, I have a bunch in bigger pots that are the same size.


logs help keep moisture in the ground and also add a continuous supply of carbon. worms breed like crazy in this compost mix.

you can see the roots. I am able to move the pots at will without worrying about breaking roots, although on concrete tiny roots do go into the ground but are easily broke with out harm to the rest of the root system.

Figure i would share as I am always looking for ways to keep plants happy in their pots as long as possible and maximize growing speed as well, There are many people also wondering the size of tree and correlation of pot size so i hope this helps. A side note that i only use rainwater or highly filtered tap water, I don't believe you will get the same results if using unfiltered city water and chemical fertilizers full of salts as it kills the soil bacteria which is the plants immune system, healthier soil healthier plants.
