Normally I would alway say that it is always best to follow the fertilization guide on the container, as every manufacturer will have a different feed ratio. In this case, for that high concentration I would use only 1/4 that strength once a month. The best fertilizers on the market are extremely expensive, and are not necessary for this case. The best that I am aware of will run you around $350 USD for a box, so you can see that it may not be the most efficient way to grow a single tree in a pot.

The only thing else I would say would be to add a little calcium and magnesium to this. Dolomitic lime will provide this, as well as keeping the soil pH balanced.
