How to pot your plant! By
Bob Little
First lets assume you already have your plant or
tree and you have found just the perfect planter for it that will fit the great
location. If you need some advise in that area please see: How
to Find, select and buy the proper planter. before going any further. 
You have several options when potting your plant, depending on if you intend it to be for indoors, outdoors or both.
First consider: If outside do you need it to drain? Usually so
or it will turn into a bog after rains. Will it be in an area that freezes? Some
planters like ceramics may not be the best choice outside in these areas. Is
there a strong wind possible? You may need to add some ballast or consider a
very heavy planter. In that case you may want to upsize it a bit. If used
inside the above may not be a problem but also think about the plant and the
location it is to be used in. We don't want a top-heavy cane or palm to fall
over when the cat jumps on it do we?
Inside (tropical) plants: The way we recommend it - is to leave your plant in the *grow pot and just drop in the decorative planter / liner. Obviously the new planter will need to be a couple of inches larger to accept the grow pot as well as deep enough to hide it. It is a good idea to use a cheap, saucer "inside" the liner to catch water so it wont just rust, sweat or rot your plant. Remember most houseplants do NOT like to sit in water, so you don't need a huge saucer but one is recommended. Some folks like to put in some stones to raise the plant up a bit instead. I don't really like that because of the danger of future leaks, mold, smells, etc. Nothing smells worse then old stagnate water! We also recommend some type of pad under the planter to further protect floor surfaces from scratches, and any future possible leaks. Even the best planters can develop a leak or sweat over time if water is allowed to stand. Fertilizers also can eat away at the inside of planters causing corrosion..
After Using the techniques above you will want to spread a nice
Spanish moss, stone, bark chips or some other ground cover (I like to use Ivy
when practical) to finish off the job. Your plant should now look great and be
very easy to care for. If it ever needs to be replaced, you can very simply pull
it out and set the new one right back in...No fuss no mess. Don't fertilize for
the first few months.
Outside: Depending on location, size and materials you may be able to use the same technique as above but often you will need to direct plant your tree into your planter.
First cover the drain holes (if any) with some window screen or other very porous material to prevent the loss (and mess) of soil and pebbles. I do like to have an inch or two of stone drainage included before planting just to be safe, but it is not always necessary. Fill the bottom with some good quality soil and place the plant in the container, leaving an inch or more at the top so soil wont run out when watering. It's a good idea to loosen up the roots (root ball) before doing this. If the root ball has a tarp or strings, cut this before planting. Some root bound trees need to have the roots cut a bit to encourage growth also. Don't go crazy but take a sharp knife and just make a bunch of slices through the outer roots. This will encourage new feeder roots to grow.
Water it in well and check for any air pockets or settling, fill in as needed. Again, a nice ground cover will finish it off nicely.
