White dots on leaves
 

Hi, my daughter was given an olive tree bonzai for her Christmas which is sadly dying. It has white marks on the leaves and is at the end of it's life now, I think.
I want to replace it with a tree that will last for the next 20 years that she can look back on knowing that she has had it since a child. I am a novice for bonzai's.
What reasonably priced tree would be a good option?
Thanks in advance

White dots on leaves
 

First of all, it is spelled bonsai.
I suggest before you buy another bonsai, try to figure out what went wrong with the first one. Where were you keeping it? An olive tree is not a good choice for a beginner's bonsai.
Consider whether you want a tropical or temperate tree. The easiest temperate tree for beginners is Chinese elm, Ulmus parvifolia. Go to a reputable bonsai nursery. Do NOT buy one from anyone who tells you it is an indoor tree; it is not. You can easily find care instructions online. Start with Bonsai4me.com. You will keep it outdoors from spring to fall. In the winter you must keep it in a cool sheltered spot where it can go dormant.
The easiest indoor tree is a Ficus. Again, buy one from a reputable bonsai nursery, not a garden centre or supermarket. Keep it outdoors in full sun spring, summer, and fall. Most Ficus will be all right on a SUNNY windowsill for the winter. Under fluorescent lights is better. Contact your nearest bonsai club for more help.

Thanks Iris,
There is a bonsai tree specialist about 30 miles from where we live, I will take my daughter for a trip this Easter and get her an outdoor tree that is more suitable.
I wish I had kept the receipt from the garden centre as a couple of months for a bonsai is rather sad.
