Bonsai just means that the plant is kept small by containing in a pot with periodic trimming of growth.

Take your "bonsai" Sago and repot into a larger container, add sun, fertilizer and water and you will have what you are looking for.

But MOST importantly, this is not a plant for indoors. It must be grown outside during the spring-summer-fall. You can bring it inside during the winter as long as you water it minimally.

For all intents and purposes, it is not possible to provide sufficient warmth and sun indoors (full time) to keep this plant healthy and attractive.

If you are looking for a houseplant, search elsewhere.

I agree 100%. A bonsai sago is just a name they give sago palms when small and they have a decorative pot and some nice rocks or maybe mulch. It probably sells better when you say its a bonsai. They say its a bonsai but in my opinion, unless you really love the challenge of making and maintaining bonsai, its better off in a real pot with real soil. I have had "bonsai" sago palms before and the rocks are sometimes glued all around the entire plant which isnt very healthy, but you can keep it in that pot until it outgrows it in a year or so. It should be watered well and kept outside in warmer months. It will make a "flush" which are just a new set of leaves usually 2 times a year, but sometimes only once. A larger plant can have 10-20 leaves in a flush but smaller plants have less. When its making a flush it must be in full sun or else you get streched out leaves which sometimes looks nice, but it isnt very proportional to the other leaves and makes the plant very easy to fall in the wind.
If you are looking for a houseplant and only a houseplant I think peace lilies and parlor palms are great. They are always growing and both bloom pretty often also. They love a sunny window. African violets are also very nice. They stay small, but there flowers dont go unnoticed. I just keep mine by a sunny window and water it every time it looks dry at it is almost always in flower (right now its full of them). They are easy. Corn plants (not the one you get corn from) also make great houseplants and can flower when older (mine have yet to do that though). They grow slow making them perfect for the home and can be bought at nice sizes.
Dont get me wrong, sagos have no problem being indoors and mine did great until that new flush of leaves came and the leaves got too long from the lack of sun. They probably wont even flush out very often indoors because its not warm and sunny enough. I wouldnt expect a flush indoors more than every year and a half unless you take it out for the summer.
And with any plant, if you want it to get big and healthy, fertilize it every once in a while, most plants really love it!

Good luck!

Thanks for the info above poster this will come in handy for reference later on. I'm trying to collect as much info on bonsai as I can since I just got started.
