california: I recently bought a kit to grow a California Redwood bonsai tree. I am wondering how long it will take to grow. I have researched it a lot and have found much information on proper care and feeding; however, none of these sources will tell me the length that this tree will take to reach maturity. Thank you|||Well technically there is no right answer to this question. The best answer is: a very long time. Basically when growing a bonsai like a redwood from seed you need it to grow to a certain height at which you trim it and keep it from growing any larger, then you have to wait many years (you will need about 10-20) before it will start to resemble more of a tree than a seedling. From there the longer you keep it and care for it, the better and more "mature" it will look, but there really is no such thing as a mature bonsai tree age. If you want to have faster results, I recommend you buy a pre bonsai redwood and start from there (will save you 5-10 years). Hope this helps!
