They are very hearty and very affordable. We took a trip to a specific bonsai store, we probably paid a little more for our bonsai then we would have if we bought it from a big box store but we get a bunch of extra's that we wouldn't have gotten from the big box store. For one, free re-potting for life, two, if our bonsai gets "sick" they will take it in and revive it and three, we have free trimming for life. Another bonus of going to the big box store was we got to pick out the color of our pot and the color of the rocks to make sure they matched our decor.
The cost was very reasonable:
The tree was: $12.99
The pot and tray: $9.99
The rocks: $2.99 (for added drainage in the tray)
The tiny Hut: $0.99
Total Project Cost: $26.96
Side note: Juniper Bonsai's thrive during warmer months outside. So for now our little fella is spending his time on the deck but come early fall he'll be making his appearance indoors.
