One More Peach Tree

I'm not sure why it was capped at 4, but may we please have one more Peach Tree? It seems very odd to me that this particular "tree" (that looks more like a bush) should be limited to 4, while the Coffee, Blackberry, and Blueberry bushes are capped at 5, and all the other trees are either capped at 8 (Cocoa, Apple, Orange, Lemon) or 5 like the bushes (Banana, Pear).

Why not just have all of them capped at the same number. Maybe 10?

I have no idea how they decided on the quantities. But having only 4 peach trees when everything else is either 5 or 8 just seems strange to me.
